Methods and systems for transmitting data through an aggregated connection

Abstract

The present invention discloses methods and systems for processing data packets received at a first network node and for processing encapsulating packets received at a second network node. The first network node receives data packets from its network interface. It then selects a first tunnel and selects none or at least one second tunnel according to a selection policy. Original encapsulating packets (OEPs) are transmitted to a second network node through the first tunnel and at least one duplicate encapsulating packet (DEP) is transmitted through the at least one second tunnel. The second network node receives an encapsulating packet with a global sequence number (GSN) through an aggregated connection. The second network node determines whether one or more data packets corresponding to the encapsulating packet have been received earlier. The second network node may then determine whether or not to forward the one or more data packets.
