Abstract

The invention discloses an IP address distribution method, a controller and a gateway device in an SDN-EPS. The method applied to the SDN controller comprises the steps that the SDN controller sends flow table information used for capturing an address distribution signaling downwards to the gateway device, receives the address distribution signaling captured by the gateway device according to the flow table information and responses to the address distribution signaling. The distribution method and system, the controller and the gateway device which are provided by the invention solve the problem that IP address management is unavailable in the SDN-EPS network because a control surface and a forwarding surface are separated.

Description

technical field

[0001] The present invention relates to the field of mobile communication, in particular to a method for allocating IP addresses in a Software Defined Network (SDN for short)-Evolved Packet System (EPS for short) network, a controller and a gateway device. Background technique

[0002] In the existing technology, the OpenFlow protocol is a forwarding / control separation protocol proposed by Stanford University in 2008. The external control plane entity uses the OpenFlow protocol to control the forwarding plane equipment to realize various forwarding logics, and the main function of the forwarding plane equipment is Controlled forwarding according to the flow table issued by the OpenFlow controller. The OpenFlow protocol has further evolved into a software-defined network (Software Defined Network, referred to as SDN) technology, that is, software programming can be used on the control plane to implement various complex network applications, for example, using ...
