Embodiment Construction

[0025] In order to solve the above-mentioned technical problems, the present invention proposes a kind of route updating method based on RIP protocol, the technical scheme of the embodiment of the present invention is:

[0026] figure 1 It is a flowchart of the technical solution of the present invention, wherein the first routing device and the second routing device are neighbor devices, and the second routing device sends a routing update message to the first routing device, including the following steps:

[0027] Step 101: The first routing device calculates the processing time of a single routing update message and the maximum sending rate of the routing update message sent by the second routing device according to the received single routing update message from the second routing device.

[0028] In this step, the single routing update message sent by the second routing device received by the first routing device is after the first routing device sends the routing update ...

Abstract

The invention discloses a routing update method based on the routing information protocol. The method includes: the first routing device calculates the processing time of a single routing updating message and the second The routing device sends the maximum sending rate of the routing update message, and carries the calculated single routing update message processing time and the maximum sending rate in the routing update request message and sends it to the second routing device, so that the second routing device periodically sends The routing update message group is sent to the first routing device to update the local routing table of the first routing device. The number of routing update messages contained in the routing update message group is not greater than the maximum sending rate, and the sending cycle of the routing update message group is not less than The product of the number of routing update packets contained in the routing update packet actually sent by the second routing device and the processing time of a single routing update packet.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a routing update method and device based on routing information protocol. Background technique [0002] The Routing Information Protocol (Routing Information Protocol, RIP) is a protocol based on the Distance-Vector (Distance-Vector) algorithm, and it exchanges routing information through User Datagram Protocol (User Datagram Protocol, UDP) messages. [0003] Each router running the RIP protocol manages a routing database, which contains routing entries to all reachable destinations, and these routing entries contain the following information: [0004] (1) Destination address: the address of the host or network. [0005] (2) Next hop address: In order to reach the destination, the interface IP address of the adjacent router that needs to pass through. [0006] (3) Outbound interface: the outbound interface through which the router forwards packets. [0007] (4) Metric v...
