Method, system and media server for establishing multicast channel

Founds method, system thereof and media server multicast channel

technical field

[0001] The invention relates to a interactive network television (IPTV) use field, the invention claims a method, system thereof and media server a base multicast channel of.

Background method

[0002] The multicast method and unicast prior art, comprising a network bandwidth of the power transmission suitable base of the user strip-shaped along with the advantage of grows, and bellows (IPTV media server and bearing network load. Therefore, a high-efficient and deploys IPTV service, economically for multicast process end of the detecting terminal-to-terminal media stream pushing. The direct broadcasting program energy to the user terminal by the bearing network, there are two multicast: modedynamic multicast mode and static multicast mode. A lower dynamic multicast mode, a exchanger and device is then all receiving groove (multicast group) and user is added request, wherein receiving and transmitting the releasing channel, programAnd the channel (multicast group) having user elements, AC on-off scram arranged on the multicast stream. Multicast static mode static distributing each groove (multicast group) is exchange device multicast routing entry and transmitting entry, no matter second circuit and a watching, a multicast provided with eight to a network element device. The electrostatic multicast groove; the channel switching speed of user is fast, service sensing is good, which is in a network bandwidth demand; No matter the dynamic multicast capable of realizing network traffic minimizing which are condition, possibly, when the user receiving the new groove (multicast group) fixed with a multiple time. Currently and static multicast groove of the lifting user experience.

[0003] The IPTV media server a plurality of media is generally, and providing broadcasting service for receiving program current integrated equal; the network port the global network, each multicast channel possibly a random port, after to form the static multicast routing entry of the straight of data: devicePort of * multicast channel of. The position where I a multicast channel form's the multicast routing entry condition on the exchanger, a media server 10 port is connected with the exchanger on, wherein the Ethernet (eth) l port emit's multicast channel the lower form 10 multicast routing clauses (sl, g1) on the exchanger, wherein form's exchanger ge2 corresponding to the gelO 9 clauses is a redundancy entry. The founds channels 300, the lower is 3000 clauses on the exchanger, wherein the exchanger the multicast entry of the limit, generally from 1000 to 2000, wherein the printed with the media server multicast channel of.
