Abstract

The invention relates to a method to definite-time list item process in communication device. It uses time label counter parameter when taking definite-time process to the item on list. Thus, the precision of definite-time process is improved. Moreover, it can adjust the precision by adjusting the number of counter of the time label. The invention could satisfy the request of precision of different people. And it is especially suited for ageing treatment for communication device. For example, the invention is used to take ageing treatment for MAC address list, even if the ageing refresh granularity precision request of MAC address is not very high during process, the maximum error may caused is only half of threshold value of ageing time, when the width of the chosen time label is one.

Description

technical field

[0001] The invention relates to the technical field of network communication, in particular to a method and a device for periodically processing entries in a communication device. Background technique

[0002] In the field of network communication technology, it often involves the need to regularly process the entries in a certain table, for example, for each dynamically maintained MAC address in the MAC (Media Access Control) address table in the switch Table entries need to be aged regularly. Similarly, there are other entries in the network communication equipment that have similar processing requirements to the MAC address table, such as frame buffer address management. For the allocated frame buffer address, if a certain If the frame buffer address allocated by this abnormal situation cannot be returned, then only protective measures are taken, that is, if the frame buffer address is not returned within the specified time (ie, the aging time threshold), ...
