METHOD AND APPARATUS FOR MITIGATING BUFFERING DELAY AT A NETWORK EDGE

摘要

A method for mitigating buffering delay in a TCP- encapsulated data stream transmitted over a network, the method comprising conducting the following steps at a node (200) in said network: receiving a first packet through a first interface (241), said first packet comprising data of said TCP- encapsulated data stream; receiving a second packet through a second interface (211), said second packet comprising an acknowledgment of segments of said TCP - encapsulated data stream; analyzing said first packet and said second packet to estimate an amount of outstanding data; using said amount of outstanding data to determine a state of buffer occupancy; updating a TCP Window field in said second packet in function of said state of buffer occupancy, and transmitting said updated second packet through said first interface.
