ID, the ID of ID and this CPU of this groove position, CCU place.
Step S305, obtains the information of all LPU in the machine frame of this equipment place, and wherein, this information includes: this LPU institute
ID and the ID of groove position, place at machine frame；
Step S306, obtains the ID of all CPU on each LPU；
Thus, by step S305 and step S306, the address information having obtained the CPU on LPU is this LPU place machine frame
ID, the ID of ID and this CPU of this groove position, LPU place.
Obviously, if this equipment place machine frame does not exist MPU, CCU or LPU, then it is performed without the obtaining step of correspondence.
Step S202, sends LSP (Link State PDUs, the link-state protocol carrying the address information got
Data cell) message；
In actual implementation process, need to add the address information got in step S301～step S306 to TLV
In (Type Length Value, type lengths values), then, this TLV is added in LSP message and sends, and should
LSP message is saved in LSDB (Link State DataBase, LSD).
In Intermediate System to Intermediate System, LSP message is to use the mode flooded to send, such that it is able to flood in group system
Other cluster-specific equipment all.Other cluster-specific equipment also can send and carry this other cluster-specific equipment and get
The LSP message of address information.
Step S203, receives the LSP message carrying address information that other cluster-specific equipment is sent.
In step S203, the LSP message received also can be saved in LSDB.
Step S204, for each address information carried in the LSP message received, uses SPF (Shortest
Path First, SPF) agreement, calculate the route of the CPU identified from this equipment to this address information.
When carrying out router-level topology, for each address information carried in the LSP message received, calculate from originally setting
The shortest forward-path of the standby CPU identified to this address information, if having calculated at least two forward-paths the shortest, i.e. this
Article at least two, the Cost (expense) of the shortest forward-path is equal, then select the conduct meeting predetermined condition from this equipment to this
The route of CPU, adds to corresponding route table items in route forwarding table as shown in table 1.
Table 1
| Destination address information | Next hop information |
Next hop information in table 1 includes: this equipment connects the interface (i.e. outgoing interface) of next-hop device and this next
The MAC Address etc. of jumping equipment.
Wherein, above-mentioned predetermined condition such as may is that the ID of outgoing interface is maximum or minimum.
Owing to CPU is positioned on cluster device, therefore, the route from this equipment to this CPU calculated is this equipment
The route of CPU to this CPU, be also to the route of this CPU place cluster device from this equipment simultaneously.
Thus, it is intended that the CPU on cluster device can utilize the route that the embodiment of the present application method calculates, to different machines
Other CPU in frame conducts interviews, it is also possible to conduct interviews other CPU in same machine frame.Further, since prior art
The default route of other cluster device in same machine frame is preserved, therefore, when not running Intermediate System to Intermediate System on cluster device
MPU with LPU on the CPU cluster device (for convenience, referred to as purpose cluster device) that needs to access in different machine frames
On CPU time, default route can be first passed through and arrive the cluster-specific equipment in same machine frame, this cluster-specific equipment passes through again
The route that the embodiment of the present application method calculates arrives the CPU on purpose cluster device.Thus, finally achieve in group system
CPU between exchanging visit.
Follow-up, when the cluster device in machine frame there occurs change, such as, increase cluster device newly or decreased cluster
Equipment, now, as it is shown in figure 5, local terminal cluster-specific equipment can perform following steps:
Step S401, it is judged that whether increasing newly or decrease cluster device in the machine frame of this equipment place, setting if having increased cluster newly
Standby, then performing step S402, if decreasing cluster device, then performing step S404；
Wherein, newly-increased cluster device can be MPU, CCU or LPU, the cluster device of minimizing can be MPU, CCU or
LPU。
Step S402, the address information of all CPU on cluster device that acquisition is newly-increased；
Step S403, sends the LSP message of the address information of the CPU carried on newly-increased cluster device；
In actual implementation process, can the address information of the CPU on newly-increased cluster device be added in TLV, so
After, this TLV is added in LSP message and sends, it is thus possible to flood to other cluster-specific all in group system
Equipment.After this other cluster-specific equipment receives this LSP message, can be saved in LSDB.
Step S404, the address information of the CPU on cluster device that acquisition reduces；
Step S405, searches the LSP message of transmission of the address information of the CPU carried on the cluster device of minimizing；
Step S406, has sent the address information of CPU on the cluster device deleting described minimizing LSP message from this
After, send this and send LSP message.
In actual implementation process, can search and carry on the cluster device of minimizing from the LSP message sent
The TLV of the address information of CPU, deletes the address information of the CPU on the cluster device of this minimizing from the TLV found, it
After this LSP message sent is sent, set it is thus possible to flood to other cluster-specific all in group system
Standby.After this other cluster-specific equipment receives this LSP message (for convenience, be designated as LSP message 1), find in LSDB
There is identical for message ID (i.e. burst number) the LSP message of reception with this LSP message, then this has been received LSP message and has updated
For this LSP message 1.
When topology group system being detected there occurs change, such as, and between direct-connected opposite end cluster-specific equipment
Is-is neighbor relation delete, establish is-is neighbor relation with direct-connected new opposite end cluster-specific equipment, link down or
Recover, this equipment place machine frame increase newly or decreases cluster device, have received the new LSP that other cluster-specific equipment is sent
Message etc., each address information that local terminal cluster-specific equipment can carry in LSP message according to receiving in LSDB, again
Calculating the route of the CPU identified from this equipment to this address information, computational methods ibid, and update route as shown in table 1
Forward table.
