Problems solved by technology

If the MAC addresses of the two PPPoE clients are the same, a PPPoE link point-to-multipoint situation will occur, that is, one PPPoE session (same Session ID) corresponds to two PPPoE clients, resulting in data processing errors

Embodiment Construction

[0024] Aiming at the above-mentioned problems existing in the prior art, the embodiment of the present invention provides a PPPoE session ID allocation scheme, which is used to solve the problem of session ID allocation conflict after the PPPoE server is restarted, to provide guarantee for data processing, and to improve the reliability of PPPoE session. After the PPPoE server discovers a conflict in the use of the session identifier, it removes the old link, speeds up the PPPoE client to rebuild the session, and improves resource utilization. In addition, it also prevents the PPPoE client from still sending through the faulty link before it perceives the PPPoE link fault. CPU resource waste caused by data.

[0025] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] The PPPoE session identification allocation scheme provided by the embodiment of the present invention is applied to a system including a ...

Abstract

The invention discloses a PPPoE session identification distribution method and device. The method includes: after the PPPoE server receives the PPPoE request sent by the PPPoE client, selects a session identifier in an idle state, and broadcasts a detection request message carrying the session identifier and the MAC address of the server; If a probe response message carrying the session ID returned by the PPPoE client is received, the PPPoE link corresponding to the session ID between the PPPoE client returning the probe response message is removed, and the The session identifier is assigned to the PPPoE client that sends the PPPoE request; otherwise, the session identifier is assigned to the PPPoE client that sends the PPPoE request. The invention can solve the problem of the conflict of session identification allocation after the restart of the PPPoE server, and improve the reliability of the PPPoE session.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a method and equipment for allocating PPPoE session identifiers. Background technique [0002] PPPoE (Point-to-Point Protocol over Ethernet, point-to-point protocol carried on Ethernet) can provide Internet access services for hosts on Ethernet through a remote access device, and realize control and billing functions for each accessed host , and are widely used in environments such as community networking. [0003] The PPPoE protocol adopts the Client / Server (client / server) method, encapsulates the PPP message in the Ethernet frame, and provides a point-to-point connection on the Ethernet. The PPPoE server uniquely identifies the session based on the MAC (MediaAccess Control, Media Access Control) address and session ID (Session ID) of the peer PPPoE client device. On the same PPPoE server, if multiple PPPoE clients with the same MAC address request to establish ...
