Abstract
The invention discloses a method for transmitting a multimedia multicasting service. The method comprises the following steps of: centralized controlling a request for multimedia multicasting by using a management server, making a decision by the management server according to the requirement of the service and the status of network resources, and if the resources can satisfy the request for the multimedia multicasting service, configuring a route message of a route node related to the service by the management server and reserving resources for the service so as to finish the building of a multicasting network. The method builds the multicasting network in the manner of concentrated control of the management server so the method is characterized by safety and high efficiency. Resources are reserved for the multicasting network in the network node, a high prior service is provided and a higher service quality is ensured.
Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of transmission method of multimedia multicast service.
Background technology
Along with the development of multimedia services such as video conference in the Internet, video request program and Streaming Media, multicasting technology has become the wideband multimedia key technologies for application.But at present relatively poor, the service quality of the manageability of multicast network can't effectively be guaranteed in the Internet, can't adapt to the demand of following multimedia service.
At present multicast application uses Internet igmpinternet (IGMP) to support main frame and router to carry out multicast.The IGMP agreement is positioned at the IP layer, with the main frame member who helps in the router identification multicast network.IGMP uses the multicast group address 224.0.0.1 that reserves to communicate by letter with local router.Router sends the IGMP inquiry to this address in local area network (LAN), main frame is organized and responded by telling them which wants to link.IGMPv1 has two types message: report (Report) and inquiry (Query).Report message and mail to router by main frame, apply for information mails to main frame by router.
In real network, to realize the forwarding of multicast packet, must on each InterWorking Equipment, move the multicast routing protocol of interoperable.Multicast routing protocol can be divided three classes: dense mode agreement (as the distance vector multicast routing protocol), sparse mode protocol (if any nuclear tree multicast routing protocol) and link-state protocol (open multicast OSPF).
The present invention proposes a kind of new multicast transmission method, need not to come managing multicast router and multicast recipient by conventional I GMP agreement, adopts the mode of management server centralized management, thereby has reduced a lot of network services, has reduced the network service cost.

Describe the present invention below with reference to the accompanying drawings in detail, it is more obvious that purpose of the present invention and effect will become.
Fig. 1 is the topology of networks schematic diagram.It is made up of some router nodes, management server, multicast packet source and a multicast packet recipient.
The present invention is for providing a kind of sending, receiving method of multimedia multicast service.This method comprises:
1. the building process of multicast network:
A. multicast service provider proposes to make up the request of multicast service to management server;
B. management server is according to the demand of business and consider the operating position of Internet resources, and whether decision accepts this request;
C. if the fruit management server is not accepted this multicast service request, then feed back the refusal solicited message to the keeper;
