Embodiment Construction

[0036] The present invention will be described below in conjunction with the accompanying drawings.

[0037] see figure 1 It is a schematic diagram of a system architecture of a data communication device according to an embodiment of the present invention.

[0038] The data communication device can be a router or a switch, which can realize the function of packet forwarding of network data.

[0039] The data communication device includes a main control board and N service boards branched from the main control board. figure 2 The given N service boards are service board 1, service board 2... and service board N.

[0040] The main control board is used to control and manage the data communication equipment system, and has an ARP table management module, and the main control board runs the ARP table management module to update the ARP table entries on the entire system.

[0041] Each service board receives messages independently from each other and is responsible for the main...

Abstract

The invention provides a APR protocol implementation, comprising the following steps: each service board processes the received a ARP massage and synchronously reports the ARP table information on the ARP massage to a main control board; the main control board receives the ARP table information synchronously reported by the multiple service boards, and updates the total ARP table on the main control board; the main control board updates the ARP table information of multiple service boards with the updated total ARP table information. According to the invention, the multiple service boards process the received ARP protocol massages in parallel, the data communication traffic between the service boards and the main control board is reduced, the main control board updates each service board with the latest total ARP table information, and the method is suitable for ARP massage transfer of cross-board services.

Description

technical field [0001] The invention relates to the field of computer network data communication, in particular to a distributed ARP (Address Resolution Protocol) protocol implementation method in data communication equipment such as routers or switches in the field. Background technique [0002] At present, in data communication devices such as high-end routers or switches, the following two methods are mostly used for processing the ARP protocol, that is, a centralized ARP protocol processing method and a distributed ARP protocol processing method. [0003] Taking the data communication equipment in the prior art as an example, the general data communication equipment includes a main control board and a plurality of service boards connected to the main control board. The centralized ARP protocol processing method includes the following step: [0004] (1) Each service board of the data communication device receives an ARP protocol message and sends it to the main control b...
