In the case of NP failures on LPU veneers, the port on other LPU veneers can't be taken, make available port number sufficient.
In the embodiment of the present invention, in order that the flow table item that input can be based on being preserved in NP to the data of failure LPU veneers
Carry out data transmission, can be that each LPU veneer sets the LPU veneers for backing up, it is mono- to preserve another LPU by the LPU veneers for backing up
The flow table item that NP is preserved in plate, in the case of the NP failures of LPU veneers, master control borad can control the LPU veneers of input to the failure
On data, transmitted to network board via the direct channel being input between the port of the data and network board, and control institute
Network board is stated by the NP of the backup LPU veneers of the LPU veneers of the data transfer to the failure, then the LPU veneers of failure
Backup LPU veneers the flow table item of the data and the Data Matching is transmitted to described by backing up the NP of LPU veneers
Network board；The network board forwards the data according to the flow table item of the Data Matching.
Below the embodiment of the present invention so that the LPU veneers in the network equipment include a LPU veneers and the 2nd LPU veneers as an example
Illustrate.The flow table item being stored with 2nd NP of the 2nd LPU veneers in a NP of a LPU veneers.Institute
The flow table item being stored with the NP for stating a LPU veneers in the 2nd NP of the 2nd LPU veneers.
In the case of a NP failures of a LPU veneers, the number in the master control borad control input to a LPU veneers
According to, transmitted to network board via the direct channel being input between the port of the data and network board, and control the exchange
Web plate is by the 2nd NP of the data transfer to the 2nd LPU veneers.The 2nd LPU veneers, will be described by the 2nd NP
The flow table item of data and the Data Matching is transmitted to the network board.The network board is according to the Data Matching
Flow table item forwards the data.
In the case of the 2nd NP failures of the 2nd LPU veneers, the number in the master control borad control input to the 2nd LPU veneers
According to, transmitted to network board via the direct channel being input between the port of the data and network board, and control the exchange
Web plate is by a NP of the data transfer to a LPU veneers.The first LPU veneers, will be described by a NP
The flow table item of data and the Data Matching is transmitted to the network board.The network board is according to the Data Matching
Flow table item forwards the data.
To the NP by backing up LPU veneers (a LPU veneers) by taking the 2nd NP failures of the 2nd LPU veneers as an example in Fig. 4
(NP) process of carrying out data transmission is schematically illustrated.In the case of for a NP failures of a LPU veneers, pass through
2nd NP of the 2nd LPU veneers carries out data transmission process and is similar to, and will not be repeated here.
In the embodiment of the present invention, the network board forwards the data procedures according to the flow table item of the Data Matching
In, the port of the output data can be determined according to the flow table item of Data Matching.If the flow table item according to the Data Matching is true
Surely it is the port of the LPU veneers of failure to export the port of the data, then the network board should with output by network board
Direct channel between the port of data, exports the port that the data export the data to the LPU veneers of the failure.If
Flow table item according to the Data Matching determines that the port of the output data is the backup LPU veneers of the LPU veneers of failure
Port, then by the NP of the backup LPU veneers of the LPU veneers of failure, export the backup of LPU veneer of the data to failure
The port of the data is exported on LPU veneers.
In the case of a NP failures of a LPU veneers, if the flow table item according to the Data Matching determines output institute
The port for stating data is the port of a LPU veneers, then the network board is by network board and the port for exporting the data
Between direct channel, export the port that the data export the data to a LPU veneers.If according to the data
The flow table item of matching determines the port that the port of the output data is the 2nd LPU veneers, then the network board is by described
With the 2nd NP that be connected of port for exporting the data on 2nd LPU veneers, the output data are to defeated on the 2nd LPU veneers
Go out the port of the data.
In the case of the 2nd NP failures of the 2nd LPU veneers, if the flow table item according to the Data Matching determines output institute
The port for stating data is the port of the 2nd LPU veneers, then the network board is by network board and the port for exporting the data
Between direct channel, export the port that the data export the data to the 2nd LPU veneers.If according to the data
The flow table item of matching determines the port that the port of the output data is a LPU veneers, then the network board is by described
With the NP that be connected of port for exporting the data on first LPU veneers, the output data are to defeated on a LPU veneers
Go out the port of the data.
In Fig. 5 by taking the 2nd NP failures of the 2nd LPU veneers as an example to network board according to the Data Matching flow table item
The data procedures are forwarded to illustrate.In Fig. 5, the 2nd NP failures of the 2nd LPU veneers, the network equipment is according to the data
The flow table item matched somebody with somebody determines the port that the port of the output data is the 2nd LPU veneers, then the network board passes through switching network
Direct channel between plate and the port for exporting the data, exports the data and exports the data to the 2nd LPU veneers
Port.
In the embodiment of the present invention, above by the mode for every LPU veneers setting backup LPU veneers in the network equipment,
So that in the case of any LPU single board defaults, being capable of achieving the treatment carried out data transmission based on the flow table item in NP.
In the embodiment of the present invention, in the case of the NP failures of LPU veneers, the LPU of master control borad control input to the failure is mono-
Data on plate, transmit to network board, and control via the direct channel being input between the port of the data and network board
The network board is by the NP of the backup LPU veneers of the LPU veneers of the data transfer to the failure, and the LPU by failure is mono-
The backup LPU veneers of plate carry out data transmission treatment, if the currently processed business of the backup LPU veneers of the LPU veneers of failure compared with
Many, then the forwarding load for being likely to result in the backup LPU veneers of the LPU veneers of failure is larger.It is each to make in the embodiment of the present invention
Load balancing between LPU veneers, the master control borad of the network equipment can control the network board that the data transfer extremely should
Before the NP of the backup LPU veneers of the LPU veneers of failure, the loading condition of each LPU veneers is determined, however, it is determined that the network equipment
There is LPU veneer of the load less than the backup LPU veneers load of the LPU veneers of failure in LPU veneers, then can control the load small
In failure LPU veneers backup LPU veneers load LPU veneers by the flow table item in the NP of the LPU veneers of failure preserve to
In NP of the load less than the LPU veneers of the backup LPU veneers load of the LPU veneers of failure, and network board is controlled by failure
LPU veneers data transfer to the load less than failure LPU veneers backup LPU veneers load LPU veneers NP.
In the embodiment of the present invention, master control borad control network board is small to the load by the data transfer of the LPU veneers of failure
In after the NP of the LPU veneers of the backup LPU veneers load of the LPU veneers of failure, the backup LPU of the LPU veneers of failure is can control
Flow table item in the NP of the LPU veneers of the failure preserved in the NP of the backup LPU of the LPU veneers of veneer deletion failure, to discharge
The storage resource of the 2nd NP, reduces the load of the 2nd LPU veneers.
In the embodiment of the present invention so that LPU veneers include a LPU veneers, the 2nd LPU veneers and the 3rd LPU veneers as an example
Illustrate.
