METHOD AND APPARATUS FOR RECOVERING DATA MISSING IN MULTI-SOURCE HYBRID OVERLAY NETWORK

摘要

In a multi-source hybrid overlay network including a plurality of peers, an apparatus for recovering data loss occurring in the process of tree recovery includes a first counterpart peer connected to the main path recovered in the tree recovery process and at least a first peer when the data recovery policy is a pull method. It recovers data it does not have in a push method through buffer map exchange with a second counterpart peer connected through one candidate path, and sends data that the first counterpart peer does not have to the first counterpart peer in a push method. to provide.
