Wherein, this other RB equipment is the RB equipment that needs to obtain a large amount of LSP messages, as: other RB equipment is specifically as follows the RB equipment of the current TRILL of being linked into network; Perhaps, the current RB equipment that reboot operation has occurred; Perhaps, the current RB equipment that the masterslave switchover operation occurs.
take application scenarios shown in Figure 1 as example, suppose that RB4 is the RB equipment of the current TRILL of being linked into network, the perhaps current RB equipment that reboot operation has occurred, the perhaps current RB equipment that the masterslave switchover operation has occurred, : exist a plurality of needs to be synchronized to the LSP message (being the LSP message of all RB equipment in the TRILL network that records in local LSDB) of RB4 on RB3, and the LSP message that exists a plurality of needs to be synchronized to RB4 on RB5 (is the LSP message of all RB equipment in the TRILL network that records in local LSDB, its can with RB3 on to need to be synchronized to the LSP message of RB4 identical).
In the embodiment of the present invention, RB equipment utilization TRILL topology of networks is determined the synchronizing sequence of each LSP message, specifically comprise: RB equipment utilization TRILL topology of networks obtains the SPF(Short Path First take this RB equipment as root, SPF) tree, and determine RB equipment corresponding to each LSP message; RB equipment determines that the priority of synchronizing sequence of the LSP message that RB equipment nearest apart from this RB equipment on the SPF tree is corresponding is the highest, determine priority second height of the synchronizing sequence of the LSP message that RB equipment near apart from this RB equipment second on the SPF tree is corresponding, by that analogy, until determine the priority of the synchronizing sequence of LSP message corresponding apart from this RB equipment RB equipment farthest on the SPF tree.Further, RB equipment is being determined RB equipment corresponding to LSP message not on the SPF tree time, and RB equipment determines that the priority of synchronizing sequence of this LSP message is minimum.
In sum, exist a plurality of when being synchronized to the LSP message of other RB equipment on an interface of RB equipment, this RB equipment is on the SPF tree take this RB equipment as root, determine the RB equipment nearer apart from this RB equipment, the priority of the synchronizing sequence of the LSP message that it is corresponding is higher, apart from this RB equipment RB equipment far away, the priority of the synchronizing sequence of the LSP message that it is corresponding is lower.In addition, for the RB equipment on the SPF tree not, the priority of the synchronizing sequence of the LSP message that it is corresponding is minimum.
In the embodiment of the present invention, RB equipment is according to the synchronizing sequence of each LSP message, the LSP message that successively a plurality of needs is synchronized to other RB equipment sends to respectively other RB equipment, specifically comprise: RB equipment preferentially sends the highest LSP message of priority of synchronizing sequence to other RB equipment, send afterwards the high LSP message of priority second of synchronizing sequence to other RB equipment, by that analogy, the most backward other RB equipment sends the minimum LSP message of priority of synchronizing sequence.Wherein, when the priority of the synchronizing sequence of a plurality of LSP messages was identical, this RB equipment can also should send to respectively other RB equipment by a plurality of LSP messages successively according to the LSP-ID of a plurality of LSP messages, and this process of transmitting repeats no more.
Below in conjunction with application scenarios shown in Figure 1, existing realization and the embodiment of the present invention are described in detail.
In prior art, when RB4 is the RB equipment of the current TRILL of being linked into network or when the RB equipment of reboot operation having occurred or the RB equipment of masterslave switchover operation having occurred, have a plurality of synchronous LSP messages for the treatment of on the interface of the upper corresponding RB4 of RB3, RB3 treats that according to a plurality of the LSP-ID of synchronous LSP message sends the LSP message to RB4; Have a plurality of synchronous LSP messages for the treatment of on the interface of the upper corresponding RB4 of RB5, RB5 treats that according to a plurality of the LSP-ID of synchronous LSP message sends the LSP message to RB4.
The LSP-ID size order of supposing each RB equipment is consistent with the number order of RBx,: the LSP message that RB3 is at first corresponding with RB1 sends to RB4, the LSP message that RB2 is corresponding sends to RB4 afterwards, the LSP message that RB3 is corresponding sends to RB4 afterwards, the LSP message that RB5 is corresponding sends to RB4 afterwards, the LSP message that RB6 is corresponding sends to RB4 afterwards, and the LSP message that RB7 is corresponding sends to RB4 afterwards.In like manner, the LSP message that RB5 is at first corresponding with RB1 sends to RB4, the LSP message that RB2 is corresponding sends to RB4 afterwards, the LSP message that RB3 is corresponding sends to RB4 afterwards, the LSP message that RB5 is corresponding sends to RB4 afterwards, the LSP message that RB6 is corresponding sends to RB4 afterwards, and the LSP message that RB7 is corresponding sends to RB4 afterwards.
Based on this, RB4 receives at one time from the message of the LSP corresponding to RB1 of RB3 and from the message of the LSP corresponding to RB1 of RB5, receive afterwards from the message of the LSP corresponding to RB2 of RB3 and from the message of the LSP corresponding to RB2 of RB5, by that analogy.Obviously, the same time receives from the message of the LSP corresponding to RB1 of RB3 and during from the message of the LSP corresponding to RB1 of RB5, only has the LSP message of a RB1 effective, thereby cause synchronous efficiency low.
Further, RB4 can generate stable forwarding-table item after need to receiving LSP message that RB1 corresponding LSP message, RB2 corresponding LSP message, RB3 corresponding LSP message, RB5 corresponding LSP message, RB6 are corresponding and LSP message corresponding to RB7; Obviously in aforesaid way, RB4 can need to receive for a long time all LSP messages, thereby cause the forwarding-table item rise time long.
In the embodiment of the present invention, when RB4 is the RB equipment of the current TRILL of being linked into network or when the RB equipment of reboot operation having occurred or the RB equipment of masterslave switchover operation having occurred, there are a plurality of synchronous LSP messages for the treatment of on the interface of the upper corresponding RB4 of RB3, therefore RB3 obtains the SPF tree take RB3 as root, B3 is nearest due to the RB3 distance R, and the priority of the synchronizing sequence of the LSP message that therefore definite RB3 is corresponding is the highest; Due to RB1 and RB2 distance R B3 second near, therefore determine priority second height of the synchronizing sequence of the LSP message that RB1 and RB2 are corresponding; Not on SPF tree, the priority of the synchronizing sequence of the LSP message that therefore definite RB5, RB6 and RB7 corresponding is minimum due to RB5, RB6 and RB7.
The LSP-ID size order of supposing each RB equipment is consistent with the number order of RBx, and when the priority of the synchronizing sequence of a plurality of LSP messages is identical,, according to the LSP-ID of a plurality of LSP messages, should send to respectively other RB equipment by a plurality of LSP messages successively; : the LSP message that RB3 is at first corresponding with RB3 sends to RB4, the LSP message that RB1 is corresponding sends to RB4 afterwards, the LSP message that RB2 is corresponding sends to RB4 afterwards, the LSP message that RB5 is corresponding sends to RB4 afterwards, the LSP message that RB6 is corresponding sends to RB4 afterwards, and the LSP message that RB7 is corresponding sends to RB4 afterwards.
In the embodiment of the present invention, when RB4 is the RB equipment of the current TRILL of being linked into network or when the RB equipment of reboot operation having occurred or the RB equipment of masterslave switchover operation having occurred, there are a plurality of synchronous LSP messages for the treatment of on the interface of the upper corresponding RB4 of RB5, therefore RB5 obtains the SPF tree take RB5 as root, B5 is nearest due to the RB5 distance R, and the priority of the synchronizing sequence of the LSP message that therefore definite RB5 is corresponding is the highest; Due to RB6 and RB7 distance R B5 second near, therefore determine priority second height of the synchronizing sequence of the LSP message that RB6 and RB7 are corresponding; Not on SPF tree, the priority of the synchronizing sequence of the LSP message that therefore definite RB1, RB2 and RB3 corresponding is minimum due to RB1, RB2 and RB3.
The LSP-ID size order of supposing each RB equipment is consistent with the number order of RBx, and when the priority of the synchronizing sequence of a plurality of LSP messages is identical,, according to the LSP-ID of a plurality of LSP messages, should send to respectively other RB equipment by a plurality of LSP messages successively; : the LSP message that RB5 is at first corresponding with RB5 sends to RB4, the LSP message that RB6 is corresponding sends to RB4 afterwards, the LSP message that RB7 is corresponding sends to RB4 afterwards, the LSP message that RB1 is corresponding sends to RB4 afterwards, the LSP message that RB2 is corresponding sends to RB4 afterwards, and the LSP message that RB3 is corresponding sends to RB4 afterwards.
Based on said process, RB4 receives at one time from the message of the LSP corresponding to RB3 of RB3 and from the message of the LSP corresponding to RB5 of RB5, receive afterwards from the message of the LSP corresponding to RB1 of RB3 and from the message of the LSP corresponding to RB6 of RB5, receive afterwards from the message of the LSP corresponding to RB2 of RB3 and from the message of the LSP corresponding to RB7 of RB5.Obviously, the same time receives from the message of the LSP corresponding to RB3 of RB3 and during from the message of the LSP corresponding to RB5 of RB5, LSP message both is all effective, can greatly improve the synchronous efficiency of LSP message.
Further, RB4 can generate stable forwarding-table item after need to receiving LSP message that RB1 corresponding LSP message, RB2 corresponding LSP message, RB3 corresponding LSP message, RB5 corresponding LSP message, RB6 are corresponding and LSP message corresponding to RB7; Obviously in aforesaid way, RB4 can receive all LSP messages (being that RB4 only uses the half the time of prior art just can complete the synchronous of whole net LSP message) in a short period of time, thereby significantly shortens the lock in time of LSP message and the stabilization time of forwarding-table item.Further, the link of RB4 access TRILL network is more, and the synchronizing speed of the LSP message of whole net is just faster, and namely synchronous LSP message time of using just still less.
