Method and system for transferring contents based on multi-source multicast

摘要

The present invention relates to multi-source multicast transmission. The present invention relates to a multi-source multicast-based content transmission method including a plurality of multicast groups, wherein a source node of each multicast group divides original content to generate a packet. And transmitting the generated packet to a network node and a reception node included in each multicast group, wherein the network node classifies the packet based on each multicast group, and network-codes the classified packet. The node transmits the network coded packet based on the multicast group address, and the receiving node of each multicast group uses the packet received from the source node and the network coded packet received from the network node. Recovering. According to the present invention, when network coding is applied in a multi-source multicast transmission-based network, a packet is mixed and transmitted based on a multicast group, and an effective packet is delivered to a receiving node, thereby improving the effective throughput of the network. have.
