Abstract

The invention provides a method for preventing a filtering resource from being exhausted and network access equipment. The method comprises the following steps of: detecting the residual capacity of the filtering resource within a detection period; and if the residual capacity is less than or equal to a preset value, clearing the filtering resource according to the idle time and / or life cycle of each piece of information in the filtering resource. The network access equipment comprises a detection module and a clearing module. In the scheme provided by the invention, the residual capacity of the filtering resource is detected within the detection period, and the filtering resource is cleared once the residual capacity is less than the preset value, so that the filtering resource is prevented from being exhausted and access of legal users is ensured.

Description

technical field [0001] The embodiments of the present invention relate to the field of network technologies, and in particular, to a method and network access equipment for preventing filter resource exhaustion. Background technique [0002] With the rapid development of Internet technology, due to the existence of various illegal users, Internet security problems are becoming more and more serious. For example, an illegal user may use any source Internet Protocol (Internet Protocol, IP for short) address to launch an attack, disrupting network accounting and management based on the source IP address. In order to prevent such an attack based on the source IP, in the prior art, the source IP address is mapped to a media access control address (Media Access Control, MAC for short), so as to be able to identify the source of the attack, thereby quickly eliminating the network attack. [0003] Currently, network access devices generally support writing the user's IP address, MA...
