Abstract
The invention provides a method for guaranteeing smoothness of a media stream in a complex network structure. A straight through high bandwidth physical network line is built between two center nodes having frequent business contact of the system, so as to transmit audio video data between nodes guaranteeing the task, and guarantee the audio video transmission quality. When the nodes need better business services, a special line needs to be built between every two nodes to transmit the media stream required by the business, so that the problem that low network bandwidth environment cannot meet the business requirement is solved.
Description
Technical field
The invention belongs to audio/video communication field, specifically relate to ensure in a kind of complex network structures the method that Media Stream is unobstructed.
Background technology
In the distributed large-scale audio frequency and video service system of combination, the internodal networking structure of system centre comprises netted and tree-shaped, and the bandwidth of network line between each node to other Centroid is different, during different routed path transfer of data can bandwidth different, cause the real network media flow transmission environment of whole audio frequency and video service system very complicated, when carrying out media stream data communication, the difficult quality guarantee of multichannel audio-video frequency transmission.Use peak time in system, when carrying out audio video transmission task between arbitrary two nodes, internodal complex network transmission environment can affect the quality of audio video transmission, occurs the problems such as audio frequency and video card pauses, time delay is larger.And the current network configuration of custom system causes the network bandwidth cannot meet media business requirement in system between Centroid, but improve the network bandwidth cost of whole system and to do very much and consuming time too of a specified duration, be unfavorable for the expansion of user function business, therefore need to propose new method and solve this problem.
Summary of the invention
For solving the problem, the present invention proposes to ensure in a kind of complex network structures the method that Media Stream is unobstructed, by setting up a straight-through higher bandwidth physical network circuit frequently between two Centroids in the contact of audio frequency and video service system service, for the inter-node transmission audio, video data carrying out audio frequency and video service role, ensure audio video transmission quality.
Technical scheme of the present invention is achieved in that
Ensure in complex network structures to comprise the following steps the method that Media Stream is unobstructed:
Step 1, carries out direct physical connection by second piece of network interface card on the streaming media server of source Centroid and object Centroid, becomes a leased-line link, arranged by two network interface card IP simultaneously, form a local area network (LAN);
Step 2, registers in O&M terminal the special line between source Centroid and object Centroid, and registration parameter comprises: source IP address, object IP address, transmission ends slogan, special line attribute; The use strategy of special line attribute and special line, at least comprises: the priority of the transport property of special line, special line hand-off process and special line;
Step 3, center service reads the special line log-on message of local Centroid from database, when special line priority is high priority, notify that local streaming media server enables special line passage, obtain object media source IP address, complete the action of streaming media link switching, use leased-line link to carry out media flow transmission;
Step 4, streaming media server possesses the monitoring function to original link and leased-line link, the original link of Real-Time Monitoring and leased-line link network connection state and network link quality, and the Link State monitored and the service of information dispatching centre is processed;
Step 5, the link-state information that center service feeds back to according to described streaming media server judges, link-state information comprises: link connects normal, the abnormal two kinds of situations of link connection; When original link connects abnormal, center service notification streams media server carries out link switching automatically, and when leased-line link connects abnormal, center service processes according to the special line handover scheme selected in advance;
Step 6, the leased-line link that user terminal displays place Centroid has, and the object Centroid showing private line access; When user terminal receives center service alert message, manually can operate, allow described streaming media server carry out link switching, another circuit of the automatic switchback of Media Stream needed for systemic-function business be transmitted, thus realizes link switching function; Abnormal information various in link is carried out display to present simultaneously, feed back to user.
Further, in described step 2, the transport property of special line comprises one-way transmission and transmitted in both directions, one-way transmission namely only active Centroid program request object Centroid time just use special line carry out media data transmission, and during object Centroid program request source Centroid, do not use special line to carry out media stream data transmission.
Further, in described step 2, special line hand-off process comprises manual switchover and automatic switchover two schemes is selected for user, manual switchover shows as: when leased-line link occurs connecting abnormal, center service is given a warning to the user terminal being carried out program request by special line, by the manual program request image again of user terminal, recover business performed on leased-line link; Automatic switchover shows as: when leased-line link connects abnormal, the media services of center service notification streams carry out link switching automatically, allow Media Stream needed for system business transmit from original link, handover scheme comprises simultaneously: carry out program request recovery according to original medium source address, recover according to subcode stream program request, recover according to pure audio streaming on demand.
Further, in described step 2, the priority of special line comprises high priority and low priority two kinds, and during high priority, system business preferentially uses special line to carry out media flow transmission; During to low priority, system business preferentially uses original circuit to carry out media flow transmission; Register parameter to be configured in O&M terminal simultaneously, after configuration, preserve database.
Further, described step 3 is simultaneously further comprising the steps of: after leased-line link is set up, only for the transmission of stream medium data, can not transmission system signaling, and the signaling of system is still by former line transmission.
The beneficial effect that the present invention produces is: 1) further ensure that audio frequency and video service system audio frequency and video business is unobstructed; 2) improve audio frequency and video service system stability; 3) problem that low network band width environment cannot meet service needed is solved, more efficiency, economy.
