METHODS AND SYSTEMS FOR TRANSMITTING DATA THROUGH AN AGGREGATED CONNECTION

摘要

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.

1. A method for processing data packets received at a network node, comprising the steps of:
step (a): receiving data packets from a network interface of the network node; step (b): selecting a first tunnel according to a selection policy; step (c): selecting none or at least one second tunnel according to the selection policy; step (d): transmitting original encapsulating packets (OEPs) through the first tunnel, wherein the OEPs encapsulate the data packets, wherein each of the OEPs has an original encapsulating packet global sequence number (OEP-GSN); step (e): transmitting at least one duplicate encapsulating packet (DEP) through the at least one second tunnel when at least one second tunnel is selected, wherein the at least one DEP encapsulates data packet information based on at least one of the data packets, wherein each of the at least one DEP has a duplicate encapsulating packet global sequence number (DEP-GSN); wherein the OEP-GSN is stored in a field of each of the OEPs and the DEP-GSN is stored in a field of each of the at least one DEP.
