Cluster Line-card Chassis main control unit 2 connects, and is connected with the exchange frame main control unit 1 in another exchange frame 1, exchange frame main control unit 2.
When using annexation shown in Fig. 5, if control crosspoint 2 occurs exception, Cluster Line-card Chassis main control unit 1 occurs
It is abnormal, then in line card inframe, worked by Cluster Line-card Chassis main control unit 2, and the control crosspoint being connected with Cluster Line-card Chassis main control unit 2
2 there is exception, so as to cause Cluster Line-card Chassis main control unit 2 be led to the Cluster Line-card Chassis main control unit of another line card inframe
Letter, also cannot be communicated with exchange frame main control unit.
After using the annexation shown in Fig. 6, if control crosspoint 2 occurs exception, Cluster Line-card Chassis main control unit 1 occurs
It is abnormal, then in line card inframe, worked by Cluster Line-card Chassis main control unit 2, although the control with the connection of Cluster Line-card Chassis main control unit 2 exchanges single
Unit 2 occur it is abnormal, but the control crosspoint 1 being connected with Cluster Line-card Chassis main control unit 2 can with normal work, therefore, Cluster Line-card Chassis
Main control unit 2 can be communicated with the Cluster Line-card Chassis main control unit of another line card inframe, with friendship by controlling crosspoint 1
Change frame main control unit to be communicated.
When using annexation shown in Fig. 5, can transmit between control crosspoint 1 and control crosspoint 2 a large amount of
Message.And after using the annexation shown in Fig. 6, it is possible to reduce transmit between control crosspoint 1 and control crosspoint 2
Message amount, so as to solve the problems, such as bandwidth bottleneck therebetween.
The embodiment of the present application proposes a kind of network equipment (i.e. the multi-chassis cascading network equipment), and the network equipment can be using figure
Any one annexation shown in 3- Fig. 6.Wherein, the network equipment is by least one exchange frame, at least two Cluster Line-card Chassis groups
Into.Exchange frame can include exchange frame main control unit, control crosspoint, F2 crosspoints；Cluster Line-card Chassis can include Cluster Line-card Chassis
Main control unit, line card unit, F13 crosspoints.
In one example, F2 crosspoints are used for second routing of the datum plane for completing the network equipment, if F2
Crosspoint cannot normal work, then second routing can be caused to complete, so as to cause the forwarding exception of datum plane, led
Cause message cannot normal transmission, and cause service disconnection.And, if F2 crosspoints corresponding control information cannot be sent to
F2 crosspoints, may result in F2 crosspoints cannot normal work, accordingly, it would be desirable to by F2 crosspoints corresponding control information
It is sent to F2 crosspoints.
Wherein, the corresponding control information of F2 crosspoints, for configuring to F2 crosspoints, such as F2 crosspoints event
The detection of barrier, the F2 crosspoints of reset failure, the program of upgrading F2 crosspoints, list item of renewal F2 crosspoints etc..It is right
In the content of control information, can be software upgrade procedure, update list item, with regard to the content such as configuration of F2 crosspoints, this Shen
This content please be limited in embodiment.
Wherein, the corresponding control information of F2 crosspoints is safeguarded on the primary main control unit of system, and primary by system
What main control unit was issued, and the primary main control unit of system can be Cluster Line-card Chassis main control unit or exchange frame main control unit.Below
With reference to two kinds of situations, the process that issues of control information is illustrated.
If situation one, Cluster Line-card Chassis main control unit are elected as the primary main control unit of system, in one example, due to line card
Frame main control unit is connected with exchange frame main control unit by controlling crosspoint, therefore, Cluster Line-card Chassis main control unit can exchanged
During frame main control unit no exceptions, control information is sent to into exchange frame main control unit by controlling crosspoint.Due to handing over
Change frame main control unit to be connected with control crosspoint, F2 crosspoints respectively, therefore, exchange frame main control unit can be by control
Crosspoint processed receives the control information from Cluster Line-card Chassis main control unit, and the control information is sent to F2 crosspoints.
In another example, as Cluster Line-card Chassis main control unit is connected with control crosspoint, therefore, Cluster Line-card Chassis main control unit, Ke Yi
When exchange frame main control unit occurs abnormal, control information is sent to into control crosspoint.Due to controlling crosspoint and line card
Frame main control unit, F2 crosspoints connect respectively, therefore, crosspoint is controlled, can be received from Cluster Line-card Chassis main control unit
Control information, and the control information is sent to into F2 crosspoints.
Below in conjunction with the annexation shown in Fig. 4, said process is described in detail.Under this application scene, it is assumed that by
Cluster Line-card Chassis main control unit 1 safeguards the corresponding control information of F2 crosspoints, and exchange frame main control unit 1 is primary exchange frame master control list
Unit, exchange frame main control unit 2 are standby exchange frame main control unit.Based on this, in order to send control information to F2 crosspoints, hand over
The priority of the priority higher than exchange frame main control unit 2 of frame main control unit 1 is changed, the priority of exchange frame main control unit 2 is higher than
The priority of control crosspoint.
Cluster Line-card Chassis main control unit 1 can exchange single with monitor in real time exchange frame main control unit 1, exchange frame main control unit 2, control
Unit 1, the state of control crosspoint 2.If 1 no exceptions of exchange frame main control unit, and control crosspoint 1 do not occur it is different
Often, then control information is sent to exchange frame main control unit 1, exchange frame master by controlling crosspoint 1 by Cluster Line-card Chassis main control unit 1
Control unit 1 after the control information is received, by the control information be sent respectively to F2 crosspoints 1, F2 crosspoints 2,
... F2 crosspoint N1.
If there is exception in exchange frame main control unit 1 and/or control crosspoint 1, and exchange frame main control unit 2 do not occur it is different
Often, 2 no exceptions of crosspoint is controlled, then control information is sent to by Cluster Line-card Chassis main control unit 1 by controlling crosspoint 2
Control information is sent respectively to F2 exchanges after control information is received by exchange frame main control unit 2, exchange frame main control unit 2
Unit 1, F2 crosspoints 2 ... F2 crosspoint N1.
If exchange frame main control unit 1 and exchange frame main control unit 2 occur exception, control crosspoint 1 and control exchange single
First 2 no exceptions, then Cluster Line-card Chassis main control unit 1 control information is sent to into control crosspoint 1 or control crosspoint
2, crosspoint 1 or control crosspoint 2 are controlled after control information is received, control information is sent respectively to into F2 exchanges
Unit 1, F2 crosspoints 2 ... F2 crosspoint N1.
If there is exception in exchange frame main control unit 1 and exchange frame main control unit 2, control crosspoint 1 (or control is exchanged
2) there is exception in unit, but control crosspoint 2 (or control crosspoint 1) no exceptions, then Cluster Line-card Chassis master control list
Control information is sent to control crosspoint 2 (or control crosspoint 1) by unit 1, control crosspoint 2 (or control is handed over
Unit is changed 1) after control information is received, by control information be sent respectively to F2 crosspoints 1, F2 crosspoints 2 ... F2
Crosspoint N1.
Obviously, after using aforesaid way, even if there is exception in exchange frame main control unit 1 and exchange frame main control unit 2,
As long as there is a control crosspoint no exceptions in control crosspoint 1 and control crosspoint 2, it is possible to by control letter
Breath is sent to F2 crosspoints, so that F2 crosspoints can be with normal work, it is to avoid the forwarding exception of datum plane, message
Can be with normal transmission, it is to avoid service disconnection.
It is above-mentioned when being using annexation shown in Fig. 4, the example of control information is sent to F2 crosspoints, when using figure
3rd, during annexation shown in Fig. 5, Fig. 6, the process for sending control information to F2 crosspoints is similar, is in exchange frame
When main control unit 1 and exchange frame main control unit 2 occur abnormal, by the control crosspoint for exchanging inframe, control information is sent out
F2 crosspoints are given, be will not be described here.
If situation two, Cluster Line-card Chassis main control unit are elected as the primary main control unit of system, in one example, if another
There is exception in the exchange frame main control unit for exchanging inframe, then F2 of another exchange inframe is exchanged single by the exchange frame main control unit
The corresponding control information of unit is sent to another control crosspoint for exchanging inframe；So that the control crosspoint will be received
Control information be sent to another exchange inframe F2 crosspoints.If another exchanges the exchange frame main control unit of inframe not
Generation is abnormal, then the exchange frame main control unit will be the F2 crosspoints of another exchange inframe corresponding by controlling crosspoint
Control information is sent to the exchange frame main control unit that another exchanges inframe；So that another exchanges the exchange frame master control list of inframe
The control information for receiving is sent to another F2 crosspoint for exchanging inframe by unit.
By taking the annexation shown in Fig. 5 as an example, if to be elected as system primary for the exchange frame main control unit 1 in exchange frame 2
Main control unit, then the exchange frame main control unit 1 safeguard the corresponding control information of F2 crosspoints.If the exchange frame in exchange frame 1
Main control unit 1, control 1 no exceptions of crosspoint, then the exchange frame main control unit 1 in exchange frame 2 is by controlling to exchange single
Control information is sent to the exchange frame main control unit 1 in exchange frame 1 for unit 1, and the exchange frame main control unit 1 in exchange frame 1 is connecing
After receiving the control information, by the control information be sent respectively to F2 crosspoints 1, F2 crosspoints 2 ... F2 crosspoints
N1。
If there is exception in the exchange frame main control unit 1 in exchange frame 1, but the exchange frame main control unit 2 in exchange frame 1,
Control 1 no exceptions of crosspoint, then the exchange frame main control unit 1 in exchange frame 2 will control letter by controlling crosspoint 1
Breath is sent to the exchange frame main control unit 2 in exchange frame 1, and the exchange frame main control unit 2 in exchange frame 1 is receiving control letter
After breath, by the control information be sent respectively to F2 crosspoints 1, F2 crosspoints 2 ... F2 crosspoint N1.
If there is exception in the exchange frame main control unit 1 in exchange frame 1, exchange frame main control unit 2, but control crosspoint
1 no exceptions, then the exchange frame main control unit 1 in exchange frame 2 by control information be sent to control crosspoint 1 control exchange
Unit 1 after control information is received, by control information be sent respectively to F2 crosspoints 1, F2 crosspoints 2 ... F2 exchange
Unit N1.
Obviously, after using aforesaid way, even if the exchange frame main control unit 1 in exchange frame 1 and exchange frame main control unit 2
There is exception, as long as control 1 no exceptions of crosspoint, it is possible to which control information is sent to F2 crosspoints, so as to
So that F2 crosspoints can be with normal work, it is to avoid the forwarding exception of datum plane, message can be with normal transmission, it is to avoid in business
It is disconnected.
When using annexation shown in Fig. 6, the process for sending control information to F2 crosspoints is similar, here
Repeat no more.

Control crosspoint is being received after the message of Cluster Line-card Chassis main control unit, and message is sent to the main control unit of purpose frame.
If purpose frame is Cluster Line-card Chassis, the main control unit of purpose frame is Cluster Line-card Chassis main control unit；If purpose frame is exchange frame, purpose frame
Main control unit be exchange frame main control unit.Additionally, exchange frame main control unit can be by for purpose frame (this exchange frame master control list
Cluster Line-card Chassis or exchange frame outside first place exchange frame) message be sent to be connected with this exchange frame main control unit each control
Crosspoint processed.Control crosspoint is being received after the message of exchange frame main control unit, and message is sent to purpose frame
Main control unit.If purpose frame is Cluster Line-card Chassis, the main control unit of purpose frame is Cluster Line-card Chassis main control unit；If purpose frame is exchange
Frame, then the main control unit of purpose frame is exchange frame main control unit.
In one example, for the annexation shown in Fig. 3 and Fig. 5, Cluster Line-card Chassis main control unit is only handed over a control
Unit connection is changed, based on this, the message for purpose frame can be sent to and this Cluster Line-card Chassis master control list by Cluster Line-card Chassis main control unit
Message is sent to the main control unit of purpose frame for the control crosspoint of unit's connection, the control crosspoint.Enter by taking Fig. 3 as an example
Message for exchange frame is sent to control crosspoint 1 by row explanation, Cluster Line-card Chassis main control unit 1, and control crosspoint 1 will report
Text is sent to exchange frame main control unit 1.

Level.Therefore, control crosspoint 1 after message is received, the exchange frame main control unit 1 message being sent in exchange frame 1.Control
Crosspoint processed 2 after message is received, the exchange frame main control unit 1 message being sent in exchange frame 1.
Exchange frame main control unit 1 in exchange frame 1 can be respectively received from control crosspoint 1 message, from
The message of control crosspoint 2, and this two parts of messages are identical.Therefore, exchange frame main control unit 1 can retain and exchange from control
The message of unit 1, and the message from control crosspoint 2 is abandoned, or, retain the message from control crosspoint 2, and
Abandon the message from control crosspoint 1.
Obviously, after using aforesaid way, if exchange frame main control unit 1 receives the link of message from control crosspoint 1
Generation is abnormal, leads to not receive the message from control crosspoint 1, then exchange frame main control unit 1 can be with from control
Crosspoint 2 receives message, so as to ensure that message can improve message transmissions with normal transmission to exchange frame main control unit 1
Reliability.In the same manner, if exchange frame main control unit 1 occurs exception from the link that control crosspoint 2 receives message, lead to not connect
Receive from control crosspoint 2 message, then exchange frame main control unit 1 can with from control crosspoint 1 receive message,
So as to ensure that message with normal transmission to exchange frame main control unit 1, can improve the reliability of message transmissions.
