Intermodule collision detecting method, system and master control board

Abstract

A method for detecting collision between modules includes configuring address pool of NAT module on master control board, sending APR table item to master control board by interface board, deleting collision table item in APR table item then storing APR table item when collision of APR table item sent from interface board to NAT address pool configured on master board is detected out, informing interface board to delete off its stored collision table item, holding set NAT address pool data and sending NAT address pool data to interface board by master control board. The system used for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to network forwarding technology, in particular to a method, system and main control board for conflict detection between modules. Background technique [0002] A variety of modules with different functions are involved in the network forwarding technology. The same or related content may be repeatedly set or established between different modules, resulting in the incorrect execution of module functions, thus causing conflicts. In order to ensure the normal execution of module functions, conflict detection is required between modules. [0003] In the following, address resolution protocol (Address Resolution Protocol, ARP) and network translation protocol (Network Address Translation, NAT) are taken as examples for illustration. ARP is a protocol that converts IP addresses into physical addresses. Specifically, the ARP module stores a mapping table including IP addresses to physical addresses. The entries in the ARP mapping ta...
