Problems solved by technology

[0007] The deficiency of the method for analyzing the detailed information of the PPP protocol message is: to analyze all the PPP user link building messages, the processing is complicated, and the equipment is easily overloaded
[0008] The disadvantage of the method of detecting the actual online status of the user is: by detecting the actual online status of the user, when the user is found to be offline, the link will be dismantled. The impact of the physical link is too large, which may lead to dismantling by mistake
If the access device cannot correctly determine the establishment status of the PPPOE connection and the PPP connection, the processing related to the user and the upper layer PPP processing device will have an incorrect impact

Embodiment Construction

[0031] The specific implementation of the present invention will be described below with reference to the drawings.

[0032] Step 1: After the access device receives the PPP LCP config request (link control protocol configuration request) message from the user, it simulates the user to initiate the PPPOE Discovery process. When the PADS (PPPOE session confirmation) message sent by the upper PPPOE processing module is successfully received, the PPPOE connection is considered to have been established. Save the session ID.

[0033] Step 2: When the PPPOE connection status is established, encapsulate and modify the user's upstream PPPOA message to form a PPPOE encapsulated Ethernet data frame. Downstream processing is the opposite. PPPOE connection establishment does not mean that PPP connection establishment. On the basis of PPPOE connection establishment, PPP can confirm the connection establishment through further interactive processing of PPP link control protocol. After the PPP c...

Abstract

The invention disclosed a method in a different system dynamic link layer access channel to establish point-to-point agreement, including the following steps: received from the user's point-to-point communication protocol Link Control Protocol allocation request text, simulated users peer-to-peer communication protocol Ethernet initiated discovery stage process; The uplink from the users Step transfer mode point-to-point communication protocol to amend a package, a point-to-point communication protocol Packaging Ethernet data frames; peer-to-peer communication protocol connections, set up to answer Link Control Protocol Message response timer, timer set up within the waiting time; Detection no time to wait Link Control Protocol response to a newspaper article to answer, terminate the access equipment peer-to-peer communication protocol Ethernet connectivity, access equipment back to the original state, prepared to begin the new connection. This method avoids the excessive intervention of the process, can dynamic build, maintain and remove point-to-point agreement channel to ensure the efficient use of the network.

Description

Technical field [0001] The present invention relates to a method for dynamically establishing a point-to-point protocol channel, in particular to a method for dynamically establishing a point-to-point protocol channel on an alien link layer path. Background technique [0002] PPP protocol (Point-to-Point Protocol), that is, point-to-point protocol, is designed to establish a reliable point-to-point data transmission method. It can encapsulate data packets of multiple protocol types, including link layer control protocols, to establish , Configure and test data link links, network layer control protocols, to establish and configure different network layer protocols. The PPP protocol is currently the most commonly used way to connect a user's computer to a network switching device to access the Internet. [0003] In the access network that adopts ATM (Asynchronous Transfer Mode, asynchronous transfer mode) technology, users use PPPOA (PPP Over ATM, asynchronous transfer mode point-...
