Provided are a fusion device, system and method for implementing an Internet Protocol Television (IPTV) service. The fusion device integrates a Content Delivery Network (CDN) component and a network component. The CDN component receives a media service request initiated by a Set Top Box (STB), searches in a service policy template database for a service policy template matching a service type carried by the request, initiate a network support request to the network component, and uses the service policy template to provide a service for the STB after receiving a success response message fed back by the network component; and the network component searches in a network policy template database for a network policy template matching a service policy after receiving the network support request, executes the network policy template, feeds back a success response message when the execution succeeds, and uses the network policy template to provide a network resource support for the CDN component. The disclosure fuses a content delivery function and a network service function, which effectively ensures service quality of the IPTV service.

Fusion device, system and method for implementing internet protocol television service

A multicast-supported virtual local area network switching system and a method thereof comprise a switching engine, a CPU unit, further comprising a mapping storage unit for storing the mapping relationship of the virtual local area network and the multicast stream pushed to the switching system by it, and a switching table storage unit for storing the corresponding relation between ingress virtual local area network and egress virtual local area network; the switching engine receives the internet group management protocol message from the user virtual local area network and transmits the message to the CPU unit for processing, if it is Internet group management protocol join/leave message, the CPU unit looks up the mapping storage unit and forwards it in the looked-up multicast virtual local area network; the switching engine receives the Internet group management protocol messages or multicast data frames from the multicast virtual local area network and forwards them in the looked-up user virtual local area network by looking up the switching table storage unit.
