Wherein, the system for multicast control in the VOD management system utilizes a media service module to interact with users and adds a service control and management module. The service control and management module is utilized for looking up a multicast group in a preset allowable time slot at a starting time requested by users. Based on the method as above, the present invention looks up a multicast group in a preset allowable time slot at a starting time requested by users. If the multicast group is nonexistent, the present invention creates a new multicast group for the user, thus trying to save bandwidth and synchronously improving particular experience for users.
Description
Technical field
The present invention relates to the multicast control technology, particularly relate to the system and method for the multicast control in a kind of ordering business management system.
Background technology
The media content demand (telecommunication) service of IP based network is subjected to user's favor gradually.What bring thus is that Media Stream carries out the transfer bandwidth bottleneck and also is on the rise on network, particularly more obvious in the mobile communications network environment.
Traditional IP communication has dual mode: the one, between a source IP main frame and a purpose IP main frame, carry out, and be called clean culture; The 2nd, in a source IP main frame and network, carry out between all other the IP main frame, be called broadcasting.If information is sent to a plurality of particular hosts in the network but not All hosts, then or adopt broadcast mode, or by source host respectively many destination hosts in network send the IP bag with mode of unicast.Not only information can be sent to unwanted main frame when adopting broadcast mode to realize, and waste bandwidth, also may be because the route winding causes serious broadcast storm.Owing to the transmission that repeats of IP bag, the waste massive band width has also increased the load of server when adopting mode of unicast to realize.So traditional clean culture and broadcast communication mode can not solve single-point effectively and send the problem that multiple spot receives.
The IP multicast is meant that certain that in IP network packet is delivered in the network determines the node subclass, and this subclass is called multicast.The basic thought of multicast is that source host only sends a piece of data, and the destination address in this piece of data is a multicast address.All recipients in the multicast can receive same data copy, and have only the main frame in the multicast just can receive these data.
Multicast is with the obvious advantage, does not wrap to unwanted main frame because it for broadcasting, sends IP, has avoided network risks; It saves massive band width with respect to clean culture.Therefore, existing media content demand (telecommunication) service uses multicast mode mostly.
But it is handling that multicast does not consider how to satisfy the user as far as possible.Use multicast mode and send stream medium data, the reception that the user can only be passive.Because user's time point difference of beginning to watch, and the user may select modes such as F.F., playback to adjust progress in broadcast, and therefore simple multicast can't satisfy above-mentioned requirements fully.In the prior art, solution one is that same program is play in turn, the 2nd, begin a plurality of multicasts from the different time successively.The former, but, the user can only wait for that it is poor that specific aim is experienced, and the user can not control progress equally though can satisfy the requirement that all users watch in case missing starting point; The latter has satisfied the user to a certain extent and has selected and the channel of expecting to be close, but certainly will cause bandwidth to waste for no reason.
