METHODS AND SYSTEMS FOR ESTIMATING MISSING DATA

摘要

The present invention discloses methods and systems for recreating missing data packets of a data session established between a first communications router and a second communications router through an aggregated connection. The first communications router receives data packets belonging to a data session from the second communications router through the aggregated connection. The data packets are destined to a first host reachable through the first communications router. The first communications router transmits the data packets to the first host and determines whether there is one or more missing data packets. If there is one or more missing data packets, the first communications router determines global sequence number(s) (GSN) and per tunnel sequence numbers (PTSN) of the one or more missing data packets and recreates payload(s) of the one or more missing data packet(s). One or more new data packets are then transmitted to the first host. The one or more new data packets comprise payload of the one or more missing data packets and are assigned with GSN(s) and PTSN(s) of the one or more missing data packets.
