Recently I have worked on a project where I have to stream a video on Internet which will be then accessed by the Servers on different locations and those servers will then stream the same video to the sub-ordinate systems simultaneously. Using this we can reduce the Load on Main Streaming Server as well as we can save lot of bandwidth as if all the server/systems connect to the Main server directly bandwidth usage of both the server and the client will be very high.
Scenario:
1) Video will be streamed from a Server on Internet.
2) Many other Servers will connect to the Server.
3) These servers will then stream the same video on their network (e.g. on LAN).
4) Users of local system will access the video from secondary servers. Read the rest of this entry »
