SDN-based network sharing method and apparatus for supporting multiple operators

摘要

A method for performing Software Defined Network (SDN)-based network sharing by a controller to support multiple operators is provided. The method includes configuring a plurality of flow tables in which an independent packet processing operation policy is defined per operator; and transmitting the plurality of configured flow tables to a network equipment, to establish an independent packet processing operation policy per operator in the network equipment.

1. A method for performing Software Defined Network (SDN)-based network sharing by a controller to support multiple operators, the method comprising:
configuring a plurality of flow tables in which an independent packet processing operation policy is defined per operator, wherein the per-operator independent packet processing operation policy is a policy for searching for an optimized path for a packet flow per operator according to at least one of a bandwidth allocated to a link per operator, priority of per-operator packet processing, traffic statistics related to utilization of a currently used link, and existence of an operator's proxy server; and transmitting the plurality of configured flow tables to a network equipment, to establish an independent packet processing operation policy per operator in the network equipment, wherein the plurality of configured flow tables are configured to not be connected to each other in the network equipment.
