SELECTIVE CACHING IN A PACKET NETWORK AND PACKET LOSS REPAIR USING SELECTIVE CACHING

摘要

The invention relates to selective caching in a packet network and to packet loss repair in a packet network using selective caching of packets. The invention provides a method of selective caching at an intermediate node in a packet network during a packet transfer session between a sending node and at least one receiving node via the intermediate node in which packet caching is initiated depending on at least one service quality factor related to the packet transfer service provided by a transfer path between the intermediate node and at least one receiving node during the transfer session. The invention also provides a method of packet loss repair using packets cached at an intermediate node.
