Abstract

Official abstract text for this publication.

A packet processing method adapted to a software-defined network is provided. The packet processing method includes the following steps: receiving an upstream packet transmitted to a remote network from a user equipment; removing a tunnel header of the upstream packet, and transmitting the upstream packet to the remote network; receiving a downstream packet transmitted to the user equipment from the remote network; selecting one of a plurality of routing paths coupled to the user equipment to transmit the downstream packet; and adding a tunnel header corresponding to the selected routing path to the downstream packet, and transmitting the downstream packet to the user equipment through the selected routing path.

First claim

Opening claim text (preview).

What is claimed is: 1 . A packet processing method, adapted to a software-defined network, comprising: receiving an upstream packet transmitted to a remote network from a user equipment; removing a tunnel header of the upstream packet, and transmitting the upstream packet to the remote network; receiving a downstream packet transmitted to the user equipment from the remote network; selecting one of a plurality of routing paths coupled to the user equipment to transmit the downstream packet; and adding a tunnel header corresponding to the selected routing path to the downstream packet, and transmitting the downstream packet to the user equipment through the selected routing path. 2 . The packet processing method as claimed in claim 1 , further comprising: determining a transmission proportion between the routing paths according to a status of each of the routing paths by a controller; transmitting the transmission proportion from the controller to an aggregation equipment; and selecting one of the routing paths by the aggregation equipment to transmit the downstream packet according to the transmission proportion between the routing paths. 3 . The packet processing method as claimed in claim 1 , wherein for each service flow between the user equipment and the remote network, the packet processing method further comprises: receiving a plurality of upstream packets of the service flow; and sorting the upstream packets according to sequence numbers of the upstream packets, and sequentially transmitting the sorted upstream packages to the remote network. 4 . The packet processing method as claimed in claim 3 , wherein the sequence numbers are located in tunnel headers of the upstream packets.
