Embodiment Construction

[0032] Below in conjunction with accompanying drawing and embodiment the scheme of the present invention will be further described:

[0033] see figure 1 , the protocol stack routing table maintenance device in this example is composed of two parts: a routing management module and a protocol stack module, wherein the protocol stack module includes a routing table maintenance module and a message processing module;

[0034] The message processing module is used to send a message to the routing table maintenance module according to the destination IP address of the message when receiving a message (a message forwarded by the local machine or a message sent to the machine by other devices, the same below). Query the corresponding routing information, and process the corresponding message according to the query result returned by the routing table maintenance module;

[0035] The routing table maintenance module is used to maintain the local routing table and provide a routing qu...

Abstract

The invention relates to a control forwarding technology on network equipment and discloses a protocol stack routing table maintaining method. The problem that in the prior art, the processing capacity of whole equipment is lowered caused by the fact that a large amount of system internal storage is consumed because of a maintaining mode of a protocol stack routing table is solved. In the method, if a protocol stack module does not inquire route information corresponding to a message locally, the target IP address of the message is used as a key word, routing information is subscribed appointing a route management module, when the routing information of the route management module subscribed on the protocol stack module changes, the changed routing information is issued to the protocol stack module, when the routing information which is not subscribed by the protocol stack module changes, issuing is not carried out, so that the protocol stack module does not need to maintain all routing table items, and accordingly system internal storage occupying is lowered, and in addition, the invention further discloses a corresponding maintaining device which is suitable for control forwarding of the network equipment.

Description

technical field [0001] The invention relates to the control and forwarding technology of network equipment, in particular to a system and method for maintaining the routing table of the protocol stack in the network equipment. Background technique [0002] With the development of Internet technology, there are more and more new services and new functions, requiring network equipment (such as routers or switches) to ensure the robustness of the control plane and the efficient and uninterrupted forwarding of the forwarding plane, so most of the current network equipment Both are designed to separate control and forwarding, that is, the control plane and data forwarding plane run on different CPUs, the control plane is responsible for routing control and calculation, and the data forwarding plane is responsible for message forwarding, and the control and forwarding perform their own duties. , ensuring the reliability of the control plane and the efficiency of the data forwardin...
