Description
Technical field
The present invention relates to network communication technology field, more particularly to one kind builds network management and control bus in IP communication networks
Method.
Background technology
Traditional IP communication networks are based on IP technical systems, the calculating for completing to route using distributed route computing method,
And the route forwarding table of foundation generation carries out the forwarding of business datum, forms the service channel of communication network.Communication network is formed
The precondition of correct service channel is that route-exchanging device and link device etc. are configured with correct all kinds of parameters and work
In correct state.
NMS in tactics IP communication network, is worked based on service channel, at network management control center and
Transmission management control message between the built-in administration agent of managed device.Before network is introduced into normal operating conditions or work
During when there is unusual condition, service channel can become unavailable, and NMS will be unable to carry out effectively network
Management and control.Therefore, active service NMS can only play a part of to make something perfect even more perfect for communication network, it is impossible to send in realizing snow
The important function of charcoal.
Current tactics IP communication network is more fragile, it is difficult to manage, and main cause has at 2 points, one be network-based control and
Management plane is excessively complicated；Two be network before Routing Protocol establishes necessary forward table, packet can not be forwarded.
To meet actual combatization demand, should build and open i.e. open network, realize that network control is separated with service bearer.In service channel not
During energy normal work, can also realize that the management to communication network is controlled, as long as physical link connection between route-exchanging device, i.e.,
The communication capacity on basis can be provided for upper strata management and control message.
The content of the invention
The invention provides a kind of method that network management and control bus is built in IP communication networks.Network management and control bus is by handing over
The software and hardware entity changed in routing device is constituted, using network itself exchange, transfer resource, in the premise for being independent of IP routes
Under, using flooding+know route by the way of, the transmission channel of full-mesh each other, all nets are set up automatically between switching node
Network device power-up can receive management and control.As shown in Fig. 2 increasing a network management and control bus protocol software in route-exchanging device newly
Module, by the mutual collaboration between network management and control bus protocol, builds a virtual network management and control in IP communication networks
Bus, its logic are illustrated as shown in Figure 3.When service channel is available, transmitted by service channel；When service channel it is unavailable
When, management control message will be transmitted in being automatically imported network management and control bus.
Realize that the method for the present invention comprises the steps：
1) a set of network management and control bus protocol software module is designed, is embedded in the master control system of route-exchanging device；
2) increase data forwarding control strategy in the exchange network of route-exchanging device, exchange network cannot be route
The management control message of forwarding send IP protocol stack to be for further processing；
3) increase data forwarding control strategy in the IP protocol stack of route-exchanging device, IP protocol stack cannot be route
The management control message SCN Space Cable Network management and control bus protocol module of forwarding is for further processing；
4) network management and control bus protocol module will be unable to routing forwarding management control message be packaged into network management and control bus message
And routing mechanism is propagated in a network using flooding+knowing；
5) network management and control bus protocol module controls message from decapsulate management in the network management and control bus message for receiving, such as
The destination address of fruit management control message is that this node is then sent IP protocol stack to be for further processing.
The method have the benefit that：One is constructed in IP communication networks not rely on IP routes, manually need not match somebody with somebody
Put, the automatic virtual network management and control bus set up of starting shooting, provide a reliable transmission channel for management control message.Work as net
When the IP parameter configuration errors of network node or abnormal communication network route, remain able to carry out effective management and control to network.Using
Network management and control bussing technique, can increase substantially the controlled ability of communication network, realize to the continual monitoring of network,
Control, optimization, fault diagnosis etc..
