Description
Technical field
The invention belongs to Computer Multimedia Technology, particularly a kind of implementation method of the load simulator that stream media service system is tested.
Background technology
Streaming Media (Stream Media) is meant the continuous time-base media that uses the stream transmission technology in Internet/Intranet, as audio frequency, video or multimedia file.
Stream media service system can be under network environment, for the user who adopts set-top box, personal computer and other type stream media terminal provides movie-on-demand, live telecast service and other media services.
Stream media service system generally refers to head end (center) system.Generally include important component parts such as streaming media server, certificate server, charging and applied business Management Support System, video acquisition manufacturing terminal system, media content searching system, digital copyright management (DRM), media store and dissemination system.
Wherein streaming media server is the most crucial parts of stream media service system, and its management also transmits a large amount of streaming medium contents.Send the mode of Streaming Media according to it, be divided into clean culture and multicast services again.Need to set up an independent data channel between client and media server, each packet of sending from a station server can only send a client computer to, and this load mode is called clean culture.Each user must distinguish convection media server and send independent inquiry, and streaming media server must send the packet copy of being applied for to each user.The IP multicasting technology makes up a kind of network with multicast-capable, allows router once packet to be copied on a plurality of passages.Adopt the multicast mode, the separate unit server can send continuous data stream simultaneously and not have time-delay hundreds of thousands platform client computer.Streaming media server only need send a packets of information, rather than a plurality of.All send the client of request and share same packets of information.Information can send to the client computer of arbitrary address, reduces the total amount of transmission over networks packets of information.Clean culture and multicast are two kinds of main methods of service that load simulator of the present invention will be accepted.
The load of stream media service system refers to stream media terminal.Common stream media terminal generally includes set-top box, personal computer, mobile phone, palmtop PC, special information terminal etc.Stream media terminal contains a DST PLAYER.It can pass through net connection with head-end system, sends service requests such as movies on demand, and accepts the stream medium data that head-end system sends, and decodes, and plays out Streaming Media in real time.DST PLAYER also has the function of " VCR pattern " remote controller operations such as carrying out F.F., rewind down, time-out, play, stop.It is by these remote controller operation requests are sent to streaming media server, and streaming media server cooperates alternately with DST PLAYER finishes these operations.These operations are main operations of stream media service system load.It also is the main operation that load simulator of the present invention will be simulated.
