Embodiment Construction

[0035] Aiming at the defect in the prior art that the same routing information is discarded in each periodic update message due to the low buffering performance of the low-end routing equipment, and thus the routing information may never be learned, the present invention proposes Each time an update message is sent, the routing information is obtained from different locations for grouping. Before the update times out, try to make the low-end routing device receive different routing information.

[0036] The present invention provides a routing information protocol optimization method, which is applied to a system including high-end routing equipment and low-end routing equipment. The method is as follows: figure 2 shown, including the following steps:

[0037] Step 201, the high-end routing device sets a routing information update timer, and a pointer position for acquiring routing information for the first time.

[0038] Step 202 , each time the update timer expires, the hi...

Abstract

The invention discloses a method for optimizing a routing information protocol, comprising the following steps: a routing information updating timer and a pointer position for acquiring routing information for the first time are arranged on high-end routing equipment; when the updating timer exceeds time, after deviating the pointer relative to a node where the routing information is acquired previously, the high-end routing equipment acquires the routing information in the corresponding node; and the high-end routing equipment sends a routing information group package to low-end routing equipment. In the invention, a routing sending sequence is changed by a sending end to enable a receiving end to receive all routings so that the routing information loss caused by the full buffer of a low-end router can be prevented.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a routing information protocol optimization method and device. Background technique [0002] Such as figure 1 As shown, the DUT (Device Under Test, the device under test) is an aggregation layer or core layer device with high routing performance. LSW (Local Switch, local switch) 1, LSW2, . . . , LSWn are access layer devices, and their routing performance is relatively low. Each device uses RIP (Routing Information Protocol, Routing Information Protocol) as a routing protocol. When the DUT has more routing information to be synchronized to the LSW, the DUT will package these routing information into update messages and send them to the LSW; after receiving the update messages, the LSW will first store them in the buffer and then read them from the buffer and process. Due to the low performance of the LSW, after receiving a certain number of update packets, the buffer i...
