In RRPP networks, each node uses centralized model treatment RRPP messages.As shown in Fig. 2 distributed apparatus is (such as
Host node, transmission node, Edge node and assistant edge node etc.) include a master control borad and two interface boards, two RRPP
Port distribution is on two interface boards.In the receive process of RRPP messages, interface board is receiving RRPP reports by RRPP ports
Wen Hou, RRPP messages are sent to master control borad and handled.In the transmission process of RRPP messages, master control borad generation RRPP reports
Text, and RRPP messages are sent to interface board, RRPP messages are sent by RRPP ports by interface board.Above-mentioned processing mode for
It is a bigger consumption for the performance of quick detection.For example, the master control borad generation hello packet of host node, and will
Hello packet is sent to interface board 1, and interface board 1 sends hello packet by the master port on interface board 1.Host node
After interface board 2 receives hello packet by the secondary port on interface board 2, hello packet is sent to master control borad, master control
Plate determines the result of quick detection.Because the precision of quick detection is in ms ranks, hello packet is between master control borad and interface board
Transmit, the transmitting-receiving performance for quick detection has large effect.
Based on above-mentioned discovery, in the embodiment of the present invention, by the packet receiving state machine of master control borad and state machine of giving out a contract for a project all in RRPP
Independent operating on interface board where port, to avoid the straddle of RRPP messages from transmitting.
Situation one, as shown in figure 3, the distributed treatment of host node.
If the role of this node is host node, when master port is located at the interface board of host node, then need in the interface
Plate enables state machine of giving out a contract for a project, and the interface board enables transmission timer, and periodically sends the 4th link detection message (i.e.
Hello packet).Further, when secondary port is located at the interface board of host node, then need to enable packet receiving state in the interface board
Machine, and the interface board enables reception overtime timer, and receive the 4th link detection message of the master port for carrying out autonomous node；Such as
For fruit before overtime timer time-out is received, the interface board receives the 4th link of the master port come autonomous node by secondary port
Detection messages, then interface board determine that link does not break down；If before overtime timer time-out is received, the interface board passes through
Secondary port does not receive the 4th link detection message of the master port for carrying out autonomous node, then interface board determines that link breaks down, and
The information that link is broken down notifies the master control borad to host node.
Based on above-mentioned processing, when link does not break down, the interface board where master port periodically sends the 4th chain
Road detection messages, the interface board where secondary port receive the 4th link detection message, do not have message between interface board and master control borad
Interaction.Interface board where secondary port is not received come autonomous node before overtime timer time-out is received by secondary port
During four link detection message of master port, the information that link is broken down notifies the master control borad to host node, afterwards
Event handling is carried out by master control borad.
In the embodiment of the present invention, when master port is located at different interface boards from secondary port, when the interface where master port
When plate needs the ISSU to upgrade, the interface board where master port is before ISSU upgradings, to the interface board send chain where secondary port
Road detection messages, the interface board where master port is carried in the link detection message need the information that ISSU upgrades.Master port institute
Interface board ISSU upgrading complete after, to the interface board transmission link detection messages where secondary port, the link detecting
Interface board where master port is carried in message has completed the information of ISSU upgradings.Can be in the link detection message
Hello packet.
Interface of the interface board where the carrying master port from the interface board where master port is received where secondary port
When plate needs the link detection message of the information of ISSU upgradings, the interface board where master port is obtained from link detection message needs
The information for wanting ISSU to upgrade, when not receiving the 4th link detection message from the interface board where master port within a specified time
When, determine that link does not break down.Interface board where secondary port is receiving the carrying master from the interface board where master port
When interface board where port has completed the link detection message of the information of ISSU upgradings, master is obtained from link detection message
Interface board where port has completed the information of ISSU upgradings, when not receiving within a specified time from connecing where master port
During four link detection message of oralia, determine that link breaks down；When within a specified time receiving where master port
During four link detection message of interface board, determine that link does not break down.
Situation two, as shown in figure 4, the distributed treatment of transmission node.
If the role of this node is transmission node, due to the possible packet receiving of the master port of transmission node, therefore in master port
The interface board at place starts packet receiving state machine, and the interface board is handled the RRPP messages received on this interface board, without
RRPP messages are sent to master control borad.Due to the possible packet receiving in the secondary port of transmission node, therefore in the interface where secondary port
Plate starts packet receiving state machine, and the interface board is handled the RRPP messages received on this interface board, without RRPP is reported
Text is sent to master control borad.Further, when interface down (failure) of transmission node, generated by the master control borad of transmission node
Linkdown (link failure) message, and the port on the interface board for passing through transmission node sends linkdown messages.
Situation three, as shown in figure 5, the distributed treatment of fringe node.
If the role of this node is fringe node, because the edge port on fringe node only has one, and edge section
Point simply periodically sends the 3rd link detection message (i.e. Fast-Edge-Hello messages), therefore, when edge port is located at
During the interface board of fringe node, it is only necessary to state machine of giving out a contract for a project is enabled in the interface board, the interface board enables transmission timer,
And periodically send the 3rd link detection message.
Situation four, as shown in fig. 6, the distributed treatment of assistant edge node.
If the role of this node is auxiliary fringe node, because the edge port on assistant edge node only has one,
And assistant edge node simply receives the 3rd link detection message (i.e. Fast-Edge-Hello messages), therefore, works as edge port
During positioned at the interface board of assistant edge node, it is only necessary to enable packet receiving state machine in the interface board, the interface board, which enables, to be connect
Overtime timer is received, and receives the 3rd link detection message from fringe node；If at the appointed time (it is fixed to receive time-out
When device time-out time) in receive the 3rd link detection message from fringe node, then interface board determine link do not occur therefore
Barrier；If not receiving the 3rd link detection message from fringe node within a specified time, interface board determines link
Failure, and the information that link is broken down notifies the master control borad to assistant edge node.
Based on above-mentioned processing, when link does not break down, the interface board of assistant edge node is receiving overtime timer
Before time-out, the 3rd link detection message from fringe node will be received, there is no message interaction between interface board and master control borad.
When link breaks down, interface board will be unable to receive the 3rd from fringe node before overtime timer time-out is received
Link detection message, the information that interface board breaks down link notify the master control borad to assistant edge node, Zhi Houyou
Master control borad carries out event handling.
Situation five, as shown in fig. 7, the distributed treatment of striding equipment.
When two RRPP ports (Primary port and secondary port of such as host node) positioned at two different equipment (main equipment and from
Equipment) when, main equipment and slave unit have exchange channels for realizing the function of host node between main equipment and slave unit, energy
It is enough to send control message.In the case, when master port is located at slave unit, it is necessary to enable state machine of giving out a contract for a project in slave unit, and
Slave unit enables transmission timer, and periodically sends the 4th link detection message (i.e. hello packet).When secondary port is located at
, it is necessary to enable packet receiving state machine in main equipment during main equipment, and main equipment enables reception overtime timer, and receives and come from main side
4th link detection message of mouth；If before overtime timer time-out is received, received by secondary port from master port
4th link detection message, it is determined that link does not break down；If before overtime timer time-out is received, pass through secondary port
The 4th link detection message from master port is not received, it is determined that link breaks down.Aforesaid way can avoid message from existing
Transmitted between main equipment and slave unit, reduce the passage consumption of message transmissions, a certain degree of load balancing can also be realized.
In the embodiment of the present invention, when interface board needs ISSU to upgrade, if interface board is used for transmission link detection messages,
Then before ISSU upgradings, interface board notice master control borad enables transmission timer, and replaces interface board transmission link detection messages,
After ISSU upgradings are completed, interface board notice master control borad stops transmission timer, and stops replacing interface board transmission link to examine
Observe and predict text.Further, if interface board is used for receives link detection messages, before ISSU upgradings, interface board notice master
Control plate enables reception overtime timer, and replaces interface board receives link detection messages, after ISSU upgradings are completed, interface board
Notify master control borad to stop receiving overtime timer, and stop replacing interface board receives link detection messages.
In the embodiment of the present invention, when master control borad needs ISSU to upgrade, if backup master where master control borad on node be present
Plate is controlled, before ISSU upgradings, master control borad notice backup master control borad is operated instead of master control borad；In ISSU upgrading completions
