Problems solved by technology

[0008] At the same time, when the performance of the streaming media server reaches the range that the streaming media server can bear, it will inevitably lead to a decline in service quality. At this time, not only the streaming media playback effect of the subsequent orderer will be affected, but the streaming media of all clients that the streaming media server is providing services will be affected. Playback will deteriorate
[0009] 2. It brings huge bandwidth pressure to the intermediate network, and it is also easy to cause service quality to

Example Embodiment

[0037] Example 1:

[0038] Please refer to Figure 2. This embodiment 1 includes the following steps:

[0039] S1-1. When receiving the client's request instruction for the first-class media source, terminate the request instruction and maintain its connection with the client;

[0040] Generally speaking, when a client requests first-class media source data, it will send a request to the streaming media source through the router it is connected to. The request carries client information so that the streaming media source can return to the client according to the request Corresponding streaming media data, and as a result, when multiple users request the same streaming media source, the streaming media source must return multiple copies of data at the same time, which causes pressure on the streaming media source and the intermediate network.

[0041] However, in the first embodiment, the routing device terminates the request instruction when it receives the client's request, thereb...

Example Embodiment

[0063] Example 2:

[0064] In order to realize the real-time support for the change of client information in the routing proxy table during the streaming media data transmission process, this embodiment 2 provides the following technical solutions, please refer to Figure 3, including the following steps:

[0065] S2-6-1. Implement monitoring whether the client information associated with the streaming media source in the routing proxy table has changed; the change may include a new client requesting the streaming media source to join, or the original The client suspends the operation of receiving data from the streaming media source and exits.

[0066] S2-6-2. If there is no change, the current copy unicast status will be maintained;

[0067] S2-6-3. When a change occurs, according to the changed client information, the received data is copied and unicasted to the client respectively.

[0068] It can be seen that the number of copies can be updated in real time as the information ...

Example Embodiment

[0072] Example 3:

[0073] Please refer to Figure 4, embodiment 3 describes a method for realizing streaming media data transmission, which supports the original client's exit at any time during the process of receiving data from the streaming media source; the specific solution is in embodiment 1 or embodiment 2. On the basis of, it also includes the following steps:

[0074] S3-7. The routing device detects that a client has exited a media source;

[0075] Two cases can be used to illustrate:

[0076] In the first type, the routing device receives an exit instruction from the client to the first-class media source;

[0077] In the second type, the routing device does not receive the heartbeat message of the client within a preset time, and thus detects that the connection relationship with the client is disconnected. In order to implement this solution, the routing device can start a timer for the client, and if the timer expires, the routing device considers that the client has...

Abstract

The present invention discloses a method and a route device which can realize the transmission of flow media data. The method is applicable to the route device between the flow media resource and the customer terminal to provide the data transmission. The aforesaid method comprises the steps as follows: terminating a request order of the terminal customer to the flow media resource, recording the information of the flow media resource and the customer terminal and respectively maintaining the connection between the customer terminal and the flow media resource; copying the data received from the flow media resource and send the data to the relative customer terminal according to the customer terminal information of the flow media resource. The present invention can be used for transmitting the data between the flow media resource and the customer terminal. The present invention comprises a recording unit, a customer terminal maintaining unit, a flow media resource maintaining unit and a copy and transmission unit. The present invention reduces the requirement to the capability of the flow media resource and the bandwidth pressure of the medium network, and the present invention ensures the quality of the service.

Description

Technical field [0001] The invention relates to the technical field of transmission of streaming media data in Ethernet, and in particular to a method and a routing device for realizing the transmission of streaming media data. Background technique [0002] As an important communication carrier, the network is used to transmit all kinds of business data in people's production and life. It mainly includes three communication modes: unicast, broadcast and multicast (multicast). Because the scope of use of the broadcast transmission method is limited to the LAN of the Layer 2 switch, the common business data transmission method can only be selected in unicast and multicast. [0003] Theoretically speaking, the multicast transmission method can transmit data to multiple hosts that need (join the group) at one time, and will not affect the communication of other hosts that do not need (not join the group), so it also has unicast And the advantages of broadcasting are the most promisin...
