Embodiment Construction

[0110] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0111] PPPoE communication can be divided into two stages: discovery (discovery) stage and session (session) stage. The discovery phase is used for the PPPoE client and the PPPoE server to obtain the peer’s Media Access Control (MAC) address from each other, and the PPPoE server assigns a session ID (session ID) to the PPPoE client; the sessi...

Abstract

Disclosed are a processing method, device and system of a point to point protocol over Ethernet (PPPoE). The invention provides a processing method, device and system of a PPPoE. The method includes the following steps: a forwarding device receives a PPPoE control message sent by a PPPoE client; the forwarding device sends the PPPoE control message to a control device; the forwarding device receives first information sent by the control device, wherein the first information is information needed by the PPPoE client in sending a first PPPoE data message and is distributed by the control device according to the PPPoE control message; and the forwarding device sends the first information to the PPPoE client. The processing method, device and system of the PPPoE are capable of realizing support of the PPPoE under a scene in which control and forwarding are separated so that the PPPoE can be realized on an SDN device.

Description

technical field [0001] The present invention relates to communication technology, and in particular to a processing method, device and system for an Ethernet-based point-to-point protocol (Point to Point Protocol over Ethernet, PPPoE). Background technique [0002] A software-defined network (Software Defined Network, SDN) can provide an open network interface and provide network development-related applications for network equipment vendors, network operators, or third parties. Openflow protocol (Openflow, OF) is the key technology of SDN. OF is based on the architecture of separation of control and forwarding, including OF controller and OF switch. OF controller can be responsible for the processing of various protocols, running applications, and external Provide a programming interface; the OF controller can issue a flow table to the OF switch, and the OF switch forwards based on the flow table. [0003] PPPoE is a protocol widely used by network operators, and the curre...
