Embodiment Construction

[0040] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0041] In general, existing multicast technologies require the support of routers, but due to the configuration of routers and the bottleneck of upgrades due to the fact that routers are too old or do not have this function, large-scale multicasting is difficult to achieve, and the network management Difficult, cannot guarantee the quality of service.

[0042]The present invention is based on the streaming media data processing method and system of application layer multicast, adopts application layer multicast, deploys the server (edge ​​server) in the metropolitan area network close to the user end, replaces the router to complete the multicast (multicast of the router) It is completed at the network layer, and the multicast of the server is completed at the application layer), and by setting up servers uniformly, ne...

Abstract

The invention relates to a method and a system based on application-layer multicast (ALM) for processing streaming media data. The method comprises the following steps: sending a channel URL (uniformresource locator) address to request the authorization for watching the channel; accessing to a resource allocation server to request the resource allocation according to the returned address of the resource allocation server after the authorization; request a first edge server to provide streaming data according to the returned address of the first edge server sent by the resource allocation server; and receiving the streaming data sent by the first edge server. The invention further relates to an ALM-based system for processing streaming media data. Accordingly, the method and the system ofthe invention can effectively verify and monitor the streaming media data, ensure the low bandwidth consumption of backbone networks and valid authentication of user identity and right and facilitatethe actual operation and management.

Description

technical field [0001] The invention relates to a method and system for processing streaming media data based on application layer multicast, in particular to a method and system for processing live broadcast of streaming media data at the application layer. Background technique [0002] Streaming Media (Streaming Media) refers to the continuous audio / video data streams transmitted and played in chronological order on the data network. Streaming media does not need to download the entire file before playing, but only caches part of the content, so that streaming media data can be transmitted while streaming Play while playing, saving download waiting time and storage space. [0003] In the streaming media live broadcast service, users can select the channel currently being broadcast live, watch the content of the program being played at the studio in real time, and store the content while watching the broadcast program. Users can choose to join a channel and switch between ...
