Problems solved by technology

When traditional Ethernet switches process multicast packets, they simply broadcast on each port. This method makes the multicast packets flood to the network that does not support multicast. When there are many such networks, it will cause bandwidth loss. great waste

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0018] Such as figure 1 Shown, the realization system of igmpsnooping agreement under vxworks system of the present invention comprises:

[0019] The CFG (Configuration, configuration) sub-module is used for operations related to the configuration of the igmpsnooping protocol. For example, configure the enabling status of the igmpsnooping protocol, the interval for sending query packets, and the aging time of router ports.

[0020] TimerExpiry (timer overtime) sub-module, there are two port sets...

Abstract

The invention provides a system for realizing the igmpsnooping protocol under the vxworks system, including: a CFG submodule, which is used to be responsible for operations related to the configuration of the igmpsnooping protocol; a TimerExpiry submodule, which has two port sets in the state machine of the module; Packet Process module, which receives IGMP messages and performs corresponding processing according to message types; Event Handler module, mainly responds to changes in the network topology; Igmpsnooping Operation module, mainly for internal switching chips and vxworks operating systems operate. After the invention implements the igmpsnooping protocol under vxworks, it can be widely used in the fields of communication, military affairs, aviation, aerospace and the like, and has better reliability and real-time performance than linux.

Description

technical field [0001] The invention relates to an implementation system, in particular to an implementation system of the igmpsnooping protocol under the vxworks system. Background technique [0002] With the rapid development of computer and network technology, users are increasingly demanding on the quality of communication, and the demand for network bandwidth shows a linear upward trend. The needs of users are no longer limited to simple voice and data communication, and the era of multimedia video communication integrating voice, data and images has come. When traditional Ethernet switches process multicast packets, they simply broadcast on each port. This method makes the multicast packets flood to the network that does not support multicast. When there are many such networks, it will cause bandwidth loss. Great waste. Most commercial Ethernet switches use the Linux operating system. With the continuous improvement of technology, the igmpsnooping (internet group ma...
