Below in conjunction with application example of the present invention, embodiment of the present invention technique scheme is described in detail:
The point-to-point resource-sharing schedule system of application example video of the present invention can adopt distributed structure/architecture, and be easy to expansion, reliability is high, has fabulous concurrency.Relative to traditional single-point scheduler, application example video of the present invention point-to-point resource-sharing schedule system can realize being registered in the user on different scheduler, realize sharing the intercommunication of resource information, break user's barrier that single-point is followed the tracks of, improve and point-to-pointly share rate.Whole system is reliable and stable, when have server rolls off the production line time (such as proxy server), system does not need to restart or out of service, can realize reaching the standard grade or lower line process of server.System is mainly divided into proxy server and server two parts that burrow, proxy server is responsible for management and the scheduling of resource, the network in charge client id that burrows is distributed, burrow (NAT (Network Address Translation, network address translation) penetrates) and heartbeat is safeguarded.
As shown in Figure 4, be overall architecture and the mutual schematic diagram of application example system of the present invention, as shown in Figure 5, be application example service framework schematic diagram of the present invention, Fig. 4 specifically comprises:
1., after nodal terminal A (being driven or alternate manner by JS) obtains the download address of video file, nodal terminal A, to the request of service equalizer, obtains proxy server and the server address that burrows;
2., data cube computation set up by nodal terminal A and proxy server;
3., nodal terminal A sets up data cube computation with the server that burrows;
4., nodal terminal A to Proxy request the Resources list, proxy server initiates inquiry to dispatch server, then Query Result is returned to nodal terminal A;
If the Query Result 5. returned is for empty, namely also do not have nodal terminal to download this file, 8. nodal terminal A, just from CDN downloading data, jumps to;
If 6. return results not for empty, nodal terminal B has this file, nodal terminal A burrows to moving server application;
7., after nodal terminal A and nodal terminal B connects, from nodal terminal B downloading data;
8. after, nodal terminal A downloads to data, to proxy server report resource info (namely this nodal terminal existing the data resource of video file), resource information is transmitted to dispatch server by proxy server, and resource information is saved in memory database by dispatch server.
Role server function declaration in Fig. 4:
(1) control machine in
Middle control machine and control server, be responsible for detecting the whether keep-alive of other servers, maintenance service equalizer and proxy server, service equalizer with burrow server, proxy server and dispatch server, burrow server and the relation that burrows between database.Assisting by middle control machine, whole dispatching patcher achieves Consistency service framework (being described in detail afterwards).
(2) equalizer is served
Be responsible for the scheduling of proxy server and the server that burrows, according to the state status of these two kinds services, in conjunction with the geographical location information etc. of nodal terminal, nodal terminal be accurately assigned to suitable proxy server and the server that burrows.
(3) proxy server
Be responsible for nodal terminal mutual, request be given to the dispatch server of specifying by nodal terminal ID, be " agency " of dispatch server.By this role of proxy server, proxy server can realize distributed deployment, and Consumer's Experience can be better, and dispatch server can realize clustering and dispose, and manages more convenient.
(4) dispatch server
For preserving the information of nodal terminal (peer), realizing adding, the function of deletion and Query Information, by filename Hash (hash also has direct transliteration to be " Hash ") algorithm, realizing distributed and clustering management.And between dispatch server, achieve nodal terminal information sharing, break the shared barrier of single dispatch server, nodal terminal has been dispatched more reasonable, share rate higher.
(5) burrow server
Responsible node terminal ID assignment, heartbeat is safeguarded, the function that burrows (NAT penetrates).Another function realizes using the RTMFP (Real Time Media Flow Protocol, real-time media stream protocol) needed for flash p2p (point-to-point based on flash).
(6) burrow database
Be a distributed memory database service, for preserving the Back ground Information (for realizing burrowing) of nodal terminal, realize adding, deleting and inquire about the function of the information that burrows, realize distributed storage by nodal terminal ID.
The point-to-point resource-sharing schedule system of application example video of the present invention achieves Consistency service framework, and by this framework, system achieves service dispatch equilibrium assignment, improves stability and the redundancy ability of service, makes whole system more healthy and stronger.
The basic principle that realizes of application example video of the present invention point-to-point resource-sharing schedule system is, all servers all timing report and submit status data to middle control machine, the state of each server analyzed by middle control machine, determining that server state changes, such as load abnormal, network jitter, to delay machine etc., more new data is reported and submitted to Servers-all, Servers-all is after receiving status data, judge and self have the server of data interaction whether normal, if there is abnormal state, server is just no longer to this abnormal server allocating task, special in system (proxy server and the dispatch server of taking distributed type assemblies mode, burrow server and the database that burrows), just can calculate the server that can accept request by certain algorithm, request forward to this server, and perform data recovery policy.Originally be assigned to the request occurring abnormal server, and other server can be evenly distributed to, can not have an impact to integrity service while Deterministic service.Like this when certain server of internal system occurs abnormal, serve without any impact, for system outside (nodal terminal) without any change.
The point-to-point resource-sharing schedule system of application example video of the present invention adopts this technical scheme, live scheduling can be achieved with less server, in conjunction with adobe flash technology, for sports event live broadcast, support multiple terminal, play stable, while saving bandwidth, save equipment, save expenditure.Dispatch relative to traditional single-point, native system achieves the isostasy of dispatch server by service equalizer, added the structure of dispatch server by proxy server simultaneously, request is evenly distributed to the dispatch server dispatched in cluster by proxy server according to user ID, user profile is also evenly stored in different dispatch servers, realizes request and store all achieving distributed management.Meanwhile, achieve sharing of resource between dispatch server, resources centralized management makes dispatching distribution more reasonable, shares more concentrated, relative to single-point scheduling, has and higher shares rate, thus reduce bandwidth cost.
