Embodiment
First some concepts that the present invention relates to simply are introduced herein.FC network configuration process mainly comprises Four processes: host exchange election, distribution Domain_ID, FC Network reconfiguration.If following table 1 is FC network configuration flow table:
Table 1FC network configuration flow table
Switch starts and after link negotiation, if switch finds to lay oneself open to a multi-exchange environment, will cause a host exchange election process, inter-exchange is communicated by the port be connected, and elects host exchange.The Domain_ID that host exchange is responsible for all switches in whole FC network distributes.Inter-exchange elects host exchange by EFP message (being used for carrying out host exchange election and propagating in FC network the message of Domain_ID of distribution), carries priority and the switch name of switch in EFP message.In election process, the switch of priority the highest (being worth minimum) is as host exchange, if multiple stage switch priority is identical, then the switch that switch name is minimum is as host exchange.In election process, every platform switch all first think the priority of oneself and switch name minimum, record oneself priority and switch name as the priority of host exchange and switch name, send EFP message to all direct-connected neighboring switch, notice priority and the switch name of the host exchange of its record.When every platform switch receives EFP message (comprising the SW_ACC response message of response EFP message), priority in message and switch name and the priority of host exchange oneself recorded and switch name are compared, if priority and the switch name of the host exchange of discovery local record are less, the host exchange then carrying local record by responding SW_ACC message notifies that the other side upgrades, and can not notify other adjacent direct-connected switch; If the priority of the host exchange of discovery local record and switch name are larger, then upgrade priority and the switch name of the host exchange of local record, and the adjacent direct-connected switch to other sends the renewal of EFP message notifying.Like this, by between two relatively can select priority and the minimum switch of switch name as host exchange, and each switch have recorded priority and the switch name of host exchange, and the switch name of host exchange is as FC network of network.
When starting switch election, every platform switch all can start the timer that time-out time is 2*F_S_TOV (defaulting to 5 seconds).After timer expiry, every platform switch all can do following judgement: the host exchange priority of local record is 0XFF, then representing in whole FC network does not have switch to become host exchange, then makes the interconnected port of the inter-exchange of all unlatchings enter isolation; If the host exchange priority of local record is identical with switch name with the priority of oneself with switch name, then the machine is as host exchange, starts to distribute Domain_ID.
After host exchange is elected, host exchange will be responsible for each switch in whole FC network and distribute Domain_ID; First host exchange distributes Domain_ID to oneself, and then send DIA message (message of notice application Domain_ID) to its adjacent direct-connected downstream switch, notice starts to apply for Domain_ID.After downstream switch receives DIA message, can arrange the link receiving DIA message is upstream primary link, and sends RDI message (application distributes the message of Domain_ID), for asking Domain_ID to host exchange.After host exchange receives RDI request message, for it distributes Domain_ID, and send back message to it.After non-principal switches receives the back message of host exchange, the Domain_ID of self is set, and then sending DIA message to its downstream neighboring switch (except the primary link of upstream other adjacent direct-connected downstream switch), notice downstream neighbor starts to apply for Domain_ID.After downstream switch receives DIA message, send RDI message request and distribute Domain_ID, this RDI message is passed through upstream primary link to host exchange direction forwarding by the intermediary switch sending DIA message to it, after distributing Domain_ID by host exchange, send back message, after intermediary switch receives back message, then this back message is transmitted to the switch in downstream, the switch in such downstream just gets Domain_ID by the mode of hop-by-hop.
Between Domain_ID allotment period, all switches also need to record the E port receiving RDI request message, and ISL belonging to this E port is the downstream primary link of switch.Host exchange (comprises when often distributing a Domain_ID and distributing to oneself), the all downstream switch Domain_ID of EFP message notifying to be sent to downstream primary link to distribute and upgrade (Domain_ID list comprises the switch name of all Domain_ID of having distributed and corresponding switch in whole FC network).Receive the switch of EFP message, upgrade the Domain_ID list that the machine is preserved, and forward the EFP message received to downstream primary link, hop-by-hop carries out, until every platform switch all preserves a up-to-date Domain_ID list in whole FC network.
Non-principal switches, when to host exchange request Domain_ID, can specify the Domain_ID wanting to obtain.Host exchange, when receiving such RDI request message, can distribute the Domain_ID of application as far as possible; If this Domain_ID unavailable (such as given other switch or not allowing to distribute in the scope of Domain_ID), host exchange distributes other an available Domain_ID.After non-principal switches receives the back message of RDI, or accept this Domain_ID, or isolation receives the E port of message.The distribution of Domain_ID adopts the principle of first asking first to distribute, and first available Domain_ID is found out in every sub-distribution from Domain_ID pond.
FC Network reconfiguration occurs that FC network merges, switch leaves or network manager is triggered by factors such as orders, can be understood as FC network re-start host exchange election and Domain_ID distribution before preparation.FC Network reconfiguration, is divided into non-interrupted (Non-disruptive) and interrupts (Disruptive) and reshuffle.In non-interrupted reconfiguration course, transfer of data can not be interrupted; The transfer of data of interrupting whole FC network in reconfiguration course all can be interrupted.FC Network reconfiguration can flood BF message (BuildFabric in FC network, triggering FC network carries out non-interrupted and reshuffles) or RCF message (ReConfigureFabric, triggering FC network carries out interruption and reshuffles), and empty host exchange priority that switch preserves and host exchange name, the Domain_ID list of all switches in FC network, make FC network re-start host exchange election.
The service condition table of table 2BF/RCF:
Switch is (except just at inundation BF and RCF message) at any time, and in initiation or when receiving BF message first, start non-interrupted and reshuffle, simultaneously start-up time is that F_S_TOV(defaults to 5 seconds) timer.Before timer expiry, switch spreads BF message in FC network, the Domain_ID list of removing all switches in local host exchange priority of preserving and host exchange name, FC network prepares to carry out host exchange election, starts host exchange election process after timer expiry.Switch is (except just at inundation RCF message) at any time, in initiation or when receiving RCF message first, starts interruption and reshuffle, and simultaneously start-up time is that F_S_TOV(defaults to 5 seconds) timer.Before timer expiry, switch spreads RCF message in FC network, remove host exchange priority that the machine preserves and host exchange name, Domain_ID that the Domain_ID list of all switches in FC network, the machine are run prepares host exchange election, after timer expiry, start host exchange election process.The switch of initiating to reshuffle sends BF (RCF) message to direct-connected switch to the port that the inter-exchange of all unlatchings is interconnected; BF (RCF) message that the switch receiving BF (RCF) message receives to the port repeat that the inter-exchange except other all unlatching receiving message is interconnected is to direct-connected switch.Finally, all in FC network switches all sent or have received BF (RCF) message.
Fig. 1 is the flow chart of network integration processing method embodiment one of the present invention, as shown in Figure 1, present embodiments provides a kind of network integration processing method, can specifically comprise the steps:
Step 101, when multiple network to be fused occurs that domain identifier conflicts, according to the cutout network in the described multiple network to be fused of pre-configured network fusion policy acquisition and a non-cutout network.
When carrying out the network integration to multiple network to be fused, the edge switch in network to be fused needs to judge whether existence domain identifies Domain_ID collision problem to multiple network to be fused by network parameter negotiations process.Network to be fused herein can for completing the FC network of FC network configuration, and domain identifier is the domain identifier of the switch in network to be fused.Before the network integration, in a network to be fused, the domain identifier of switch is independently for other networks to be fused, and therefore the problem that domain identifier conflicts may appear in two or more network to be fused.In the present embodiment, when multiple network to be fused occurs that domain identifier conflicts, first according to the multiple cutout network in the multiple network to be fused of pre-configured network fusion policy acquisition and a non-cutout network.Wherein, network fusion policy is configured according to the actual conditions of FC network, and it is specially a FC network and does not interrupt convergence strategy, and it is selected to protect one of them or several network to be fused not to carry out interruption by this network fusion policy and reshuffles.This step is from multiple network to be fused, select according to this network fusion policy need to carry out interrupt reshuffling cutout network and do not need to carry out interrupting reshuffling non-cutout network.
Step 102, reshuffles optical fiber RCF message to the transmission that floods of the switch in described cutout network, carries out Network reconfiguration to make the switch in described cutout network according to described RCF message.
After getting cutout network and non-cutout network, edge switch in this step in non-cutout network only floods to the switch in cutout network and sends RCF message, and the switch stopped in network does not flood to the switch in non-cutout network and sends RCF message, and the switch in non-cutout network does not process the RCF message that the switch in cutout network sends to the switch in non-cutout network.Then, the switch in cutout network, after receiving RCF message, carries out Network reconfiguration according to this RCF message, needs cutout to wait for a period of time.But not the switch in cutout network can not receive RCF message, therefore carry out Network reconfiguration without the need to cutout.
Step 103, carries out fusion treatment by the cutout network after described non-cutout network and Network reconfiguration.
After switch in cutout network carries out Network reconfiguration, the cutout network after non-cutout network and Network reconfiguration is carried out fusion treatment.Reshuffle because a cutout network need treated in UNE in the present embodiment carries out cutout, non-cutout network is reshuffled without the need to carrying out cutout, therefore without the need to carrying out the operation of host exchange election contest, thus decreases the time of fusion taken because host exchange election contest.
Present embodiments provide a kind of network integration processing method, when multiple network to be fused occurs that domain identifier conflicts, according to the cutout network in the multiple network to be fused of pre-configured network fusion policy acquisition and non-cutout network, and edge switch in non-cutout network only floods to the switch in cutout network and sends RCF message, but not cutout network is reshuffled without the need to carrying out cutout, and the cutout network after non-cutout network and Network reconfiguration is carried out fusion treatment; The present embodiment to multiple completed FC network configuration but the FC network that Domain_ID exists conflict merges time, can to continue to flow fusion by one of them FC network, and shorten 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 embodiments provide a kind of network integration processing method, this sentences two FC networks and carries out being fused to example and be described technical scheme of the present invention, and the present embodiment can specifically comprise the steps:
Step 201, receives the RCF message that the edge switch in non-cutout network sends.
This step is the RCF message that the switch in cutout network receives the edge switch transmission in non-cutout network, this RCF message be edge switch in non-cutout network when multiple network to be fused occurs that domain identifier conflicts, send after obtaining cutout network in multiple network to be fused and a non-cutout network according to pre-configured network fusion policy.
Step 202, carries out Network reconfiguration according to RCF message.
Switch in cutout network, after receiving RCF message, carries out Network reconfiguration according to this RCF message, needs cutout to wait for a period of time.But not the switch in cutout network can not receive RCF message, therefore carry out Network reconfiguration without the need to cutout.
Step 203, carries out fusion treatment by the cutout network after non-cutout network and Network reconfiguration.
After switch in cutout network carries out Network reconfiguration, the cutout network after non-cutout network and Network reconfiguration is carried out fusion treatment.Reshuffle because a cutout network need treated in UNE in the present embodiment carries out cutout, non-cutout network is reshuffled without the need to carrying out cutout, therefore without the need to carrying out the operation of host exchange election contest, thus decreases the time of fusion taken because host exchange election contest.
Particularly, the step 203 in the present embodiment specifically can comprise the steps: the host exchange information of host exchange in the described non-cutout network of the edge switch notice received in described non-cutout network; Obtain the domain identifier that the host exchange in described non-cutout network distributes.
Present embodiments provide a kind of network integration processing method, when multiple network to be fused occurs that domain identifier conflicts, according to the cutout network in the multiple network to be fused of pre-configured network fusion policy acquisition and non-cutout network, and edge switch in non-cutout network only floods to the switch in cutout network and sends RCF message, but not cutout network is reshuffled without the need to carrying out cutout, and the cutout network after non-cutout network and Network reconfiguration is carried out fusion treatment; The present embodiment to multiple completed FC network configuration but the FC network that Domain_ID exists conflict merges time, can to continue to flow fusion by one of them FC network, and shorten 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 embodiments provide a kind of network integration processing method, this sentences two FC networks and carries out being fused to example and be described technical scheme of the present invention, and the present embodiment can specifically comprise the steps:
Step 301, when two FC networks occur that domain identifier conflicts, obtains cutout network in two FC networks and a non-cutout network according to pre-configured network fusion policy.
When the FC network having completed FC network configuration to two merges, two FC networks first carry out the negotiation of FC network parameter, find in negotiations process that domain identifier conflict appears in these two FC networks, namely in these two FC networks, certain two switch have employed identical domain identifier.When two FC networks occur that domain identifier conflicts, the present embodiment obtains cutout network in these two FC networks and a non-cutout network according to pre-configured network fusion policy.Network fusion policy herein may be used for protecting original FC network not interrupt reshuffling, and also may be used for the larger FC network of protection and does not interrupt reshuffling, can certainly arrange other Preservation tactics according to actual conditions.When network fusion policy is for the protection of original FC network, this step is the FC network newly added according to the cutout network that this network fusion policy gets, and non-cutout network is legacy network.When network fusion policy is for the protection of larger FC network, this step is the FC network that in two FC networks, scale is less according to the cutout network that this network fusion policy gets, and non-cutout network is FC network larger in two FC networks.
Step 302, floods to the switch in cutout network and sends RCF message, carry out Network reconfiguration to make the switch in described cutout network according to described RCF message.
If network fusion policy is configured to protect original FC network not interrupt reshuffling; the network that then stops is the FC network newly added; this step is that edge switch in original FC network floods to the switch in the FC network newly added and sends RCF message; make the switch in the FC network newly added carry out Network reconfiguration according to this RCF message, Network reconfiguration herein can for emptying the domain identifier of the switch in the FC network that newly adds.Edge switch in the original FC network of the present embodiment only floods to the switch in the FC network newly added and sends RCF message, and switch in the FC network newly added does not flood to the switch in original FC network and sends RCF message, the switch simultaneously in original FC network does not also process the RCF message that the switch in the FC network newly added sends to the switch in original FC network.If network fusion policy is configured to protection, larger FC network does not interrupt reshuffling; the network that then stops is the FC network that scale is less; to be edge switch in larger FC network to the switch in the less FC network of scale flood this step sends RCF message; switch in the FC network making scale less carries out Network reconfiguration according to this RCF message, and Network reconfiguration herein can for emptying the domain identifier of the switch in the less FC network of scale.Edge switch in the FC network that the present embodiment is larger only floods to the switch in the less FC network of scale and sends RCF message, and the switch in the less FC network of scale does not flood to the switch in larger FC network and sends RCF message, the switch in simultaneously larger FC network does not also process the RCF message that the switch in the less FC network of scale sends to the switch in larger FC network.
Step 303, the host exchange information of host exchange in the non-cutout network of the cutout network notifications after Network reconfiguration, and be from switch by the switch configuration in described cutout network.
After sending RCF message to the switch in the switch in the FC network newly added or the less FC network of scale, two FC networks start again to carry out the negotiation of FC network parameter.Switch in cutout network to the host exchange information of host exchange in the non-cutout network of the cutout network notifications after Network reconfiguration, and is all set to from switch by the edge switch in non-cutout network.In the present embodiment, edge switch in non-cutout network only need carry out Network reconfiguration to the FC network newly added or the less FC network of scale, and original FC network or larger FC network are without the need to carrying out Network reconfiguration, principal and subordinate's exchanger information wherein still retains.This step is specially edge switch in original FC network to the FC network notifications host exchange information newly added after Network reconfiguration, and directly by the switch configuration in the FC network that newly adds for from switch, without the need to again campaigning for host exchange again, thus avoid the time of fusion taken because of host exchange election contest.Or, this step is specially edge switch in larger FC network to the less FC network notifications host exchange information of the scale after Network reconfiguration, and be directly from switch by the switch configuration in FC network less for scale, without the need to again campaigning for host exchange again, thus avoid the time of fusion taken because of host exchange election contest.
Step 304, distribute instruction to the host exchange transmission mark in non-cutout network, described mark distribution indicates the host exchange be used to indicate in non-cutout network to identifying from switch allocation domain in described cutout network.
In two FC network convergence process, need occurring that the domain identifier of conflict is redistributed, only need redistribute the domain identifier of the switch in cutout network in the present embodiment, the domain identifier of the switch in non-cutout network can remain unchanged.When the edge switch in original FC network is from switch, this step edge switch be specially in non-cutout network sends mark to the host exchange in non-cutout network and distributes instruction, identifies to distribute to indicate the host exchange be used to indicate in non-cutout network to identifying from switch allocation domain in described cutout network.Particularly, edge switch in original FC network distributes instruction to the host exchange transmission mark in original FC network, and described mark distribution indicates the host exchange be used to indicate in original FC network to identifying from switch allocation domain in the described FC network newly added.Namely can be distribute a domain identifier from switch in the FC network newly added to the host exchange in original FC network, this domain identifier be different from the domain identifier of each switch in original FC network, thus avoids the phenomenon that occurs that domain identifier conflicts.Or, edge switch in larger FC network can initiate application to the host exchange in larger FC network, be distribute a domain identifier from switch in the FC network that scale is less by this host exchange, this domain identifier is different from the domain identifier of each switch in larger FC network, thus avoids the phenomenon that occurs that domain identifier conflicts.
Or, when the edge switch in non-cutout network is host exchange, then direct by the host exchange in non-cutout network to identifying from switch allocation domain in described cutout network, namely direct by the host exchange in original FC network to identifying from switch allocation domain in the FC network newly added, or directly by the host exchange in larger FC network to identifying from switch allocation domain in the less FC network of scale.
