Abstract
The invention discloses a network management system and method for a controlled multicast system based on multicast conversion. The system comprises a network management configuration module, a forwarding list scheduling module, a gateway communication module and a historical record operation module. The method comprises the following steps: S1, reading the configuration information in a configuration file provided by a network manager; S2, starting a scheduling algorithm and waiting for registration application of each translation gateway; S3, receiving the registration applications of the translation gateways, querying topology configuration and channel configuration of the translation gateways in a gateway topology database according to the registration applications of the translation gateways, and generating a forwarding list for the translation gateways; and S4, acquiring running state information and flow statistical information from each translation gateway periodically and carrying out the corresponding processing. According to the invention, the configuration, scheduling, management and monitoring of the translation gateways under one framework are realized and the multicast services are extended to different multicast networks, so that the translation gateways can work cooperatively.
Description
technical field [0001] The invention relates to the technical field of the Internet, in particular to a network management system and method of a controllable multicast system based on multicast conversion. Background technique [0002] High-performance video transmission systems (including video conferencing systems) with technical characteristics such as large data volumes and low delays are typical applications of the next-generation Internet. The application system itself puts forward high requirements. Currently popular video application systems include DVTS system, VLC system and high-definition uncompressed video system, with resolutions from standard definition (720×480) to high-definition (1920×1080), transmission bandwidth from 22Mbps to 800Mbps, with different characteristics, for users Provide different services for different needs. Due to the port speed limit, network congestion and other reasons, the current Internet may not be able to meet the bandwidth requ...
