Terminal access quantity control method and system

Abstract

The invention relates to the technical field of networks and discloses a terminal access number control method. The method aims to solve the problem that due to the fact that an existing distributed device can not limit the terminal access number accurately, the terminal access number exceeds limitation. The method mainly comprises the steps that a forwarding plane periodically reads media access control MAC address numbers of a port, and informs the read MAC address numbers to a control plane; the control plane checks whether records exist in a forwarding table after extracting MAC addresses of messages, and judges whether the MAC address numbers of the port reach the limitation value; if yes, a control switch of the up-sending control plane is turned off when source MAC searching fails, and processing of the messages is stopped; if not, the control switch of the up-sending control plane is turned on when source MAC searching fails so that the control plane can process the messages. The invention discloses a terminal access number control system. According to the method and the system, the terminal access numbers of the port can be controlled accurately, impact on the control plane from the messages can be reduced, and processor resources of the control plane are saved.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method and a system for accurately limiting the number of terminals connected to a port on a distributed switch device. Background technique [0002] With the development of network technology, the requirements for equipment utilization are getting higher and higher. For the current switching equipment, it is required to be able to access enough terminals and have a strong forwarding capability. When the number of connected terminals is too large, network resources will be excessively occupied, and some terminals that need network bandwidth cannot obtain enough bandwidth, resulting in too slow network speed, which affects the use of users. [0003] This problem is more obvious on distributed equipment. Distributed equipment is generally used as mid-to-high-end equipment and is used in the aggregation-level access layer in the local area network, and the number of terminals c...

AI Technical Summary

Problems solved by technology

On distributed devices, there will be two obvious problems in the access of a large number of terminal devices: First, because data packets are always sent to the data control plane, a large amount of processor resources will be consumed, which cannot adapt to the network scale and the growth of attack traffic. It also poses a great hidden danger to the normal operation of the equipment control plane

Second, the number of terminal access cannot be accurately limited, which often causes the number of terminal access to exceed the limit
