Embodiment Construction

[0021] The following combination figure 1 An embodiment of the present invention is described:

[0022] figure 1 It is a flow chart of a session distinguishing method in an embodiment of the present invention. The method includes:

[0023] 102. When it is determined that the second user equipment needs to create a second session, send a prefix allocation request to the second edge device, where the second session is different from the session already created by the client front-end device.

[0024] For example, the first user equipment behind the customer front-end equipment accesses the network through the customer front-end equipment, the customer front-end equipment obtains a 56-bit IPv6 prefix, and selects a 64-bit IPv6 prefix for the first user equipment within the range of the 56-bit IPv6 prefix. A bit IPv6 prefix is ​​assigned to the first user equipment. Afterwards, the second user equipment behind the customer front-end device needs to create a session, and the se...

Abstract

The invention relates to the field of network communications, in particular to a session distinguishing method and session distinguishing equipment. The session distinguishing method comprises the following steps of: when a second user device needs to establish a second session, transmitting a prefix distributing request towards a second edge device, wherein the second session is different to the session established by a client front-end device; receiving the distributed prefix of the second edge device according to the prefix distributing request, wherein the distributed prefix is different to a corresponding prefix of the established session of the client front-end device; and binding the prefix, a medium access control address of the second user device and a connected port. By adopting the technical scheme provided by the embodiment, because the corresponding prefix of the second session, the medium access control address of the second user device and the connected port are bound, different sessions can be distinguished on the same client front-end device and can be supplied to later devices of the same client front-end device.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a session distinguishing method and device. Background technique [0002] In the access network, an Internet Protocol session (Internet Protocol session, IP session) represents a network access connection session associated with an IP address of a user equipment, and is established between the user side and an IP edge device (Edge device) A session connection is used for network management of access users, such as billing and status. Wherein, the edge device may be a broadband network gateway (Broadband Network Gateway, BNG) or a broadband access server (Broadband Remote Access Server, BRAS), and the user side may be a customer-premises equipment (Customer-premises equipment, CPE), such as a home gateway ( Home Gateway, HGW), or the user equipment (User Equipment, UE) behind the client front-end equipment. [0003] An IP session based on Internet Protocol version 6 (IPv6) i...
