Embodiment
Earlier some notions that the present invention relates to are carried out brief account here.The FC network configuration process mainly comprises four processes: host exchange election, distribution Domain_ID, FC Network reconfiguration.Like following table 1 is FC network configuration flow table:
Table 1FC network configuration flow table
Switch starts and through after the link negotiation, if switch is found to lay oneself open to a multi-exchange environment, will cause a host exchange election process, and inter-exchange communicates through the port that links to each other, and elects host exchange.The Domain_ID that host exchange is responsible for all switches in the whole FC network distributes.Inter-exchange is elected host exchange through EFP message (being used for carrying out the message of host exchange election and the Domain_ID that propagation distributes in the FC network), carries the priority and the switch name of switch in the EFP message.In election process, the switch of priority the highest (value is minimum) is as host exchange, if many switch priority are identical, then the switch of switch name minimum is as host exchange.In election process; Every switch thinks earlier that all the priority of oneself and switch name are minimum; Write down oneself priority and switch name priority and switch name as host exchange; Send the EFP message to all direct-connected neighboring switch, announce the priority and the switch name of the host exchange of its record.When every switch is received EFP message (the SW_ACC response message that comprises response EFP message); Priority in the message and switch name priority and the switch name with the own host exchange that writes down compared; If the priority and the switch name of the host exchange of discovery local record are littler; Then notify the other side to upgrade, and can not notify other adjacent direct-connected switch through responding the host exchange that the SW_ACC message carries local record; If the priority and the switch name of the host exchange of discovery local record are bigger, then upgrade the priority and the switch name of the host exchange of local record, and upgrade to other adjacent direct-connected switch transmission EFP message notifying.Like this, can select the minimum switch of priority and switch name as host exchange through comparison in twos, and each switch all write down the priority and the switch name of host exchange, the switch name of host exchange is as the FC network of network.
When the election of beginning switch, every switch all can start the timer that time-out time is 2*F_S_TOV (defaulting to 5 seconds).Behind the timer expiry; Every switch all can be done to judge: the host exchange priority of local record is 0XFF; Then representing does not have switch can become host exchange in the whole FC network, makes the interconnected port of inter-exchange of all unlatchings get into isolation then; If the host exchange priority of local record is identical with the switch name with switch name and the priority of oneself, then this machine begins to distribute Domain_ID as host exchange.
After host exchange is elected, host exchange will be responsible for each switch distribution Domain_ID in the whole FC network; Host exchange is at first given and oneself is distributed Domain_ID, sends DIA message (message of notice application Domain_ID) to its adjacent direct-connected downstream switch then, and notice begins to apply for Domain_ID.After the downstream switch was received the DIA message, it was upper reaches primary link that the link of receiving the DIA message can be set, and sent RDI message (application distributes the message of Domain_ID) to host exchange, was used to ask Domain_ID.Host exchange is received after the RDI request message, for it distributes Domain_ID, and sends back message using to it.Non-host exchange is received after the back message using of host exchange; The Domain_ID of self is set; And then to its downstream neighboring switch (other adjacent direct-connected downstream switch except the primary link of the upper reaches) transmission DIA message, the notice downstream neighbor begins to apply for Domain_ID.After downstream switch is received the DIA message; Transmission RDI message request is distributed Domain_ID, to its intermediary switch of sending the DIA message this RDI message is transmitted to the host exchange direction through upper reaches primary link, after host exchange distribution Domain_ID; Send back message using; After intermediary switch is received back message using, this back message using is transmitted to the switch in downstream, the switch in downstream just gets access to Domain_ID through the mode of hop-by-hop so again.
Between allotment period, all switches also need write down the E port of receiving the RDI request message at Domain_ID, and ISL is the downstream primary link of switch under this E port.(comprise to oneself and distributing) when host exchange is allotted a Domain_ID at per minute; Primary link sends all downstream switch Domain_ID distribution renewals of EFP message notifying (Domain_ID tabulates, and comprises the switch name of interior all Domain_ID that distributed of whole FC network and corresponding switch) downstream.Receive the switch of EFP message, upgrade the Domain_ID tabulation that this organizational security is deposited, and primary link is transmitted the EFP message of receiving downstream, hop-by-hop carries out, and every switch is all preserved a up-to-date Domain_ID tabulation in whole FC network.
Non-host exchange can be specified and want the Domain_ID that obtains to host exchange request Domain_ID the time.Host exchange can distribute the Domain_ID of application as far as possible when receiving such RDI request message; If this Domain_ID unavailable (for example given other switch or not in allow distributing the scope of Domain_ID), host exchange distribute other an available Domain_ID.Receive the back message using of RDI when non-host exchange after, or accept this Domain_ID, or isolate the E port of receiving message.The principle that the distribution of Domain_ID adopts request earlier to distribute is earlier distributed at every turn and from the Domain_ID pond, is found out first available Domain_ID.
The FC Network reconfiguration is the merging of generation FC network, switch leaves or the network manager triggers through factors such as orders, is appreciated that host exchange is elected and the preceding preparation of Domain_ID distribution for the FC network carries out again.The FC Network reconfiguration is divided into non-interruption (Non-disruptive) and interrupts (Disruptive) and reshuffles.Transfer of data can not interrupted in the non-interruption reconfiguration course; The transfer of data of interrupting whole FC network in the reconfiguration course all can be interrupted.The FC Network reconfiguration BF message (BuildFabric that can in the FC network, flood; Triggering FC network carries out non-interruption and reshuffles) or RCF message (ReConfigureFabric; Triggering the FC network interrupts reshuffling); And empty the Domain_ID tabulation of all switches in host exchange priority that switch preserves and host exchange name, the FC network, make the FC network carry out host exchange again and elect.
The operating position table of table 2BF/RCF:
Switch is (except just at inundation BF and RCF message) at any time, when initiating or receiving the BF message first, begins non-interruption and reshuffle, and be the timer of F_S_TOV (defaulting to 5 seconds) start-up time simultaneously.Switch spreads the BF message before the timer expiry in the FC network; Remove the Domain_ID tabulation of all switches in local host exchange priority of preserving and host exchange name, the FC network and prepare to carry out the host exchange election, beginning host exchange election process behind timer expiry.Switch is (except just at inundation RCF message) at any time, when initiating or receiving the RCF message first, begins to interrupt reshuffling, and be the timer of F_S_TOV (defaulting to 5 seconds) start-up time simultaneously.Switch spreads the RCF message before the timer expiry in the FC network; Remove the Domain_ID tabulation of all switches in host exchange priority that this organizational security deposits and host exchange name, the FC network, the Domain_ID of this machine operation prepares the host exchange election, beginning host exchange election process behind timer expiry.The switch that initiation is reshuffled sends BF (RCF) message to the interconnected port of the inter-exchange of all unlatchings and gives direct-connected switch; The switch that receives BF (RCF) message is given direct-connected switch to transmitting BF (RCF) message of receiving except that the interconnected port of the inter-exchange of other all unlatchings of receiving message.Finally, all switches all sent or had received BF (RCF) message in the FC network.
Fig. 1 is the flow chart of network integration processing method embodiment one of the present invention, and as shown in Figure 1, present embodiment provides a kind of network integration processing method, can specifically comprise the steps:
To a plurality of when treating that UNE carries out the network integration, treat that the edge switch in the UNE need be judged a plurality of whether existence domain sign Domain_ID collision problems of UNE of treating through the network parameter negotiations process.The UNE of treating here can be for accomplishing the FC network of FC network configuration, and domain identifier is a domain identifier of treating the switch in the UNE.Before the network integration, a domain identifier of treating switch in the UNE is independently for other treat UNE, so the problem of domain identifier conflict may appear in two or more UNE of treating.In the present embodiment, when domain identifier when conflict appears in a plurality of UNEs of treating, obtain a plurality of a plurality of cutout networks and non-cutout networks of treating in the UNE according to pre-configured based on network fusion policy earlier.Wherein, based on network fusion policy is that the actual conditions according to the FC network are configured, and it is specially a FC network and does not interrupt convergence strategy, and it is selected to protect one of them or severally treat that UNE does not interrupt reshuffling through this based on network fusion policy.This step for according to this based on network fusion policy from a plurality of selection needs interrupt reshuffling the UNE cutout network and needs non-cutout networks of interrupting reshuffling not treated.
After getting access to cutout network and non-cutout network; Edge switch in this step in the non-cutout network only switch in the cutout network floods and sends the RCF message; And the switch in the cutout network not the switch in non-cutout network flood and send the RCF message, and the switch in the non-cutout network does not process the RCF message that the switch of switch in non-cutout network in the cutout network sends.Then, the switch in the cutout network carries out Network reconfiguration according to this RCF message after receiving the RCF message, needs cutout to wait for a period of time.But not the switch in the cutout network can not receive the RCF message, therefore need not cutout and carries out Network reconfiguration.
After switch in the cutout network carries out Network reconfiguration, the cutout network after non-cutout network and the Network reconfiguration is carried out fusion treatment.Reshuffle owing in the present embodiment the cutout network that need treat in the UNE stops, non-cutout network need not to stop and reshuffles, and therefore need not to carry out the operation of host exchange election contest, thereby has reduced the time of fusion that takies because of the host exchange election contest.
Present embodiment provides a kind of network integration processing method; When domain identifier when conflict appears in a plurality of UNEs of treating; Obtain a plurality of cutout network and non-cutout networks of treating in the UNE according to pre-configured based on network fusion policy; And the edge switch in the non-cutout network only switch in the cutout network floods and sends the RCF message, but not the cutout network need not to stop and reshuffle, and the cutout network after non-cutout network and the Network reconfiguration is carried out fusion treatment; Present embodiment is accomplished the FC network configuration but Domain_ID when existing the FC network of conflict to merge to a plurality of, the fusion that can one of them FC network continues to flow, and shortened time of fusion.
Fig. 2 is the flow chart of network integration processing method embodiment two of the present invention; As shown in Figure 2; Present embodiment provides a kind of network integration processing method, this sentence two FC networks be fused to the example technical scheme of the present invention is described, present embodiment can specifically comprise the steps:
This step receives the RCF message that the edge switch in the non-cutout network sends for the switch in the cutout network; This RCF message is that the edge switch in the non-cutout network domain identifier when conflict occur at a plurality of UNEs of treating, obtains according to pre-configured based on network fusion policy and a plurality ofly treats to send after the cutout network in the UNE and the non-cutout network.
Switch in the cutout network carries out Network reconfiguration according to this RCF message after receiving the RCF message, need cutout to wait for a period of time.But not the switch in the cutout network can not receive the RCF message, therefore need not cutout and carries out Network reconfiguration.
Step 203 is carried out fusion treatment with the cutout network after non-cutout network and the Network reconfiguration.
After switch in the cutout network carries out Network reconfiguration, the cutout network after non-cutout network and the Network reconfiguration is carried out fusion treatment.Reshuffle owing in the present embodiment the cutout network that need treat in the UNE stops, non-cutout network need not to stop and reshuffles, and therefore need not to carry out the operation of host exchange election contest, thereby has reduced the time of fusion that takies because of the host exchange election contest.
Particularly, the step 203 in the present embodiment can specifically comprise the steps: to receive the host exchange information of host exchange in the said non-cutout network of the edge switch announcement in the said non-cutout network; Obtain the domain identifier that the host exchange in the said non-cutout network distributes.
Present embodiment provides a kind of network integration processing method; When domain identifier when conflict appears in a plurality of UNEs of treating; Obtain a plurality of cutout network and non-cutout networks of treating in the UNE according to pre-configured based on network fusion policy; And the edge switch in the non-cutout network only switch in the cutout network floods and sends the RCF message, but not the cutout network need not to stop and reshuffle, and the cutout network after non-cutout network and the Network reconfiguration is carried out fusion treatment; Present embodiment is accomplished the FC network configuration but Domain_ID when existing the FC network of conflict to merge to a plurality of, the fusion that can one of them FC network continues to flow, and shortened time of fusion.
Fig. 3 is the flow chart of network integration processing method embodiment three of the present invention; As shown in Figure 3; Present embodiment provides a kind of network integration processing method, this sentence two FC networks be fused to the example technical scheme of the present invention is described, present embodiment can specifically comprise the steps:
Step 301 when the domain identifier conflict appears in two FC networks, is obtained two cutout network and non-cutout networks in the FC network according to pre-configured based on network fusion policy.
When the FC network of having accomplished the FC network configuration to two merges; Two FC networks carry out the FC network parameter earlier to be consulted; Find in the negotiations process that the domain identifier conflict appears in these two FC networks, promptly certain two switch has adopted identical domain identifier in these two FC networks.When the domain identifier conflict appearred in two FC networks, present embodiment obtained cutout network and a non-cutout network in these two FC networks according to pre-configured based on network fusion policy.The based on network fusion policy here can be used to protect original FC network not interrupt reshuffling, and also can be used to protect larger FC network not interrupt reshuffling, and can certainly other protection strategies be set according to actual conditions.When based on network fusion policy was used to protect original FC network, the cutout network that this step gets access to according to this based on network fusion policy was initiate FC network, and non-cutout network is a legacy network.When based on network fusion policy was used to protect larger FC network, the cutout network that this step gets access to according to this based on network fusion policy was the less FC network of scale in two FC networks, and non-cutout network is a FC network larger in two FC networks.
Step 302, the switch in the cutout network floods and sends the RCF message, so that the switch in the said cutout network carries out Network reconfiguration according to said RCF message.
If based on network fusion policy is configured to protect original FC network not interrupt reshuffling; The network that then stops is initiate FC network; This step is that the switch of edge switch in initiate FC network in original FC network floods and send the RCF message; Make the switch in the initiate FC network carry out Network reconfiguration according to this RCF message, the Network reconfiguration here can be for emptying the domain identifier of the switch in the initiate FC network.Edge switch in the original FC network of the present embodiment only switch in initiate FC network floods and sends the RCF message; And the switch in the initiate FC network not the switch in original FC network flood and send the RCF message, the RCF message that yet the switch of the switch in the initiate FC network in original FC network do not sent of the switch in original FC network is not handled simultaneously.If based on network fusion policy is configured to protect larger FC network not interrupt reshuffling; The network that then stops is the less FC network of scale; This step is that the switch of edge switch in the less FC network of scale in the larger FC network floods and send the RCF message; Make the switch in the less FC network of scale carry out Network reconfiguration according to this RCF message, the Network reconfiguration here can be the domain identifier of the switch in the less FC network of the scale of emptying.Edge switch in the larger FC network of the present embodiment only switch in the less FC network of scale floods and sends the RCF message; And the switch in the less FC network of scale not the switch in larger FC network flood and send the RCF message, the RCF message that the switch in the simultaneously larger FC network does not also send the switch of the switch in the less FC network of scale in larger FC network is not handled.
Step 303, the host exchange information of host exchange in the non-cutout network of the cutout network notifications after Network reconfiguration, and the switch in the said cutout network is set to from switch.
After switch in the less FC network of the switch in initiate FC network or scale sent the RCF message, two FC networks begin to carry out once more the FC network parameter to be consulted.The host exchange information of host exchange in the non-cutout network of the cutout network notifications of edge switch in the non-cutout network after Network reconfiguration, and the switch in the network that will stop all is set to from switch.In the present embodiment; Edge switch in the non-cutout network only needs initiate FC network or the less FC network of scale are carried out Network reconfiguration; And original FC network or larger FC network need not to carry out Network reconfiguration, and principal and subordinate's exchanger information wherein still keeps.This step is specially the initiate FC network notifications host exchange information of edge switch after Network reconfiguration in original FC network; And the switch in the direct initiate FC network is set to from switch; Need not to campaign for again again host exchange, thereby avoided campaigning for the time of fusion that takies because of host exchange.Perhaps; This step is specially the less FC network notifications host exchange information of the scale of edge switch after Network reconfiguration in the larger FC network; And directly the switch in the less FC network of scale is set to from switch; Need not to campaign for again again host exchange, thereby avoided campaigning for the time of fusion that takies because of host exchange.
Step 304, the host exchange in non-cutout network are sent sign and are distributed indication, and said sign distributes indication to be used for indicating host exchange the identifying from the switch allocation domain in said cutout network of non-cutout network.
In two FC network convergence process, need redistribute the domain identifier that conflict occurs, only need in the present embodiment domain identifier of the switch in the cutout network is redistributed, the domain identifier of the switch in the non-cutout network can remain unchanged.When the edge switch in original FC network is during from switch; The host exchange of edge switch in non-cutout network that this step is specially in the non-cutout network sends sign distribution indication, and sign distributes indication to be used for indicating host exchange the identifying from the switch allocation domain in said cutout network of non-cutout network.Particularly; The host exchange of edge switch in original FC network in original FC network sends sign and distributes indication, and said sign distributes indication to be used for indicating host exchange the identifying from the switch allocation domain in said initiate FC network of original FC network.Promptly can be to distribute a domain identifier from switch in the initiate FC network to the host exchange in original FC network, this domain identifier be different from the domain identifier of each switch in original FC network, thereby avoids occurring the phenomenon of domain identifier conflict.Perhaps; Edge switch in the larger FC network can be initiated application to the host exchange in the larger FC network; By this host exchange is to distribute a domain identifier from switch in the less FC network of scale; This domain identifier is different from the domain identifier of each switch in the larger FC network, thereby avoids occurring the phenomenon of domain identifier conflict.
Perhaps; When the edge switch in the non-cutout network is host exchange; Then directly by the identifying in said cutout network of the host exchange in the non-cutout network from the switch allocation domain; Promptly directly by the identifying in initiate FC network of the host exchange in original FC network, perhaps directly by the identifying in the less FC network of scale of the host exchange in the larger FC network from the switch allocation domain from the switch allocation domain.
Fig. 4 is the mutual sketch map of the FC network integration among the network integration processing method embodiment three of the present invention; As shown in Figure 4, this sentences and treats that UNE is that original FC network A and initiate FC network B are that example describes, and comprises switch 1 and switch 2 in the FC network A; It is the switch that SW_NAME is respectively 0X1 and 0X3; This moment switch 1 be the host exchange in the FC network A, switch 2 be in the FC network A from switch, comprise switch 3 in the FC network B; Be that SW_NAME is the switch of 0X2, this moment, switch 3 was the host exchange in the FC network B.When FC network A and FC network B merged, the two advanced line link was consulted.After accomplishing link negotiation, FC network A and FC network B are carried out the FC network parameter and are consulted, and in the process of carrying out the negotiation of FC network parameter, the Domain_ID that detects the switch 3 in switch 2 and the FC network B in the FC network A conflicts.When the Domain_ID conflict occurring; Obtaining the cutout network according to pre-configured based on network fusion policy is the FC network B; Non-cutout network is the FC network A, and 3 switches 2 in the FC network B of switch in the FC network A flood and send the RCF message at this moment, and the FC network B is interrupted reshuffling.Wait for F_S_TOV (about 5 seconds) then, think F_S_TOV during this period of time in accomplished the whole net of FC network B RCF flood.FC network A and FC network B are carried out the FC network parameter once more and are consulted; Be the switch 2 announcement host exchange information of switch 3 in the FC network B in the FC network A; Through the network negotiate process switch in the FC network B 3 is set to from switch, thereby need not to carry out again the host exchange election contest.Apply for Domain_ID from switch 3 through exchanging 1 to the master then, apply for that Domain_ID is 0x3, no longer form and conflict with other switches from switch 2.
Present embodiment provides a kind of network integration processing method; When domain identifier when conflict appears in a plurality of UNEs of treating; Obtain a plurality of cutout network and non-cutout networks of treating in the UNE according to pre-configured based on network fusion policy; And the edge switch in the non-cutout network only switch in the cutout network floods and sends the RCF message, but not the cutout network need not to stop and reshuffle, and the cutout network after non-cutout network and the Network reconfiguration is carried out fusion treatment; Present embodiment is accomplished the FC network configuration but Domain_ID when existing the FC network of conflict to merge to a plurality of, the fusion that can one of them FC network continues to flow, and shortened time of fusion.
