Embodiment Construction

[0058] The present invention will be further described in detail through specific embodiments and in conjunction with the accompanying drawings.

[0059] see Figure 6 , is a schematic diagram of networking of an implementation manner of the access system of the present invention. The access system of the present invention includes several home gateways RG, access nodes AN, access controller (Access Concentrator), AAA server, address server and IP edge. There are several residential gateways RG (Residential Gateway) connected to the access node AN. The access node AN is connected to the IP edge through the packet switching network PSN, and the access node AN is also connected to the access controller. This connection can be directly connected, or It is connected through network logic, and the access controller is respectively connected with the AAA server and the address server. The connection may be directly connected or connected through network logic. AN identifies PPPoX ...

Abstract

The invention discloses an access system, which comprises a user device, an access node and an access controller. The access controller is connected with the access node and accesses in the user device. The access node accesses in the user device and distinguishes forwarding controlling from a data message. The controlling message is transferred and the user data message is transmitted between the user and the access controller. The benefit resulted from the technology is that the access controller in the invention manages a PPP and the access network realizes isolation between controlling and transmission, thus removing the obstacle of supporting the multicast by the PPP and solving the problems of difficulty and instability existing in the access server.

Description

technical field [0001] The present invention mainly relates to the technical field of communication, in particular to an access system and method. Background technique [0002] The Point to Point Protocol (abbreviation: PPP) provides a standard method for transmitting multi-protocol data packets over a point-to-point connection. PPP was originally designed to provide an encapsulation protocol for traffic transmission between two peer nodes. In the TCP-IP protocol set it is a data link layer protocol used for synchronous modulation connections. [0003] PPP mainly consists of the following parts: [0004] Encapsulation: A method of encapsulating multi-protocol datagrams. PPP encapsulation provides multiplexing technology for simultaneous transmission of different network layer protocols on the same link. The PPP package is carefully designed to maintain compatibility with most commonly used hardware; [0005] Link Control Protocol (LCP): The LCP provided by PPP is compre...
