<p>Method and system for multicasting circular transmission data in data network, which including following steps : a. A server transmits a group of data to one or more segments with 'scale' which is stored in the memory ; b. Providing catalogue information for client machines ; c. Separately and circularly transmitting data which is need to be transmitted by network to respective multicasting packet ; d. The client machine randomly adds one or more multicasting packets for receiving data according to the received catalogue information, and register the origin point at the time of starting receiving according to the scale of data segment, then checking and connecting data. The system which used said method can relieve the load of servers and the backbone of network, moreover, it can download data momentary, immediately and reliably, and it can also use data as soon as possible, so that the user who used the client machine timely, conveniently and reliably feels like unicasting.</p> |
