Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] In the embodiment of the present invention, the PPP agreement and the PPPoE agreement are encapsulated in a software module PPP / PPPoE module to realize, the user process starts the PPP / PPPoE module at first, after this module completes the PPPoE discovery phase, loads the PPP agreement in the session phase of PPPoE, Establish and maintain PPP links.

[0025] In the embodiment of the present invention, the PPP protocol and the PPPoE protocol are encapsulated in a software module (PPP / PPPoE module). PPP is started by PPPoE, and PPPoE is started by a user process through the PPP / PPPoE module. ...

Abstract

The invention is applicable to the field of broadband access and provides a device and a method for establishing a PPP link based on a TCP / IP protocol. The device includes a PPP / PPPoE module. The PPP / PPPoE module is sealed with a PPP protocol and a PPPoE protocol. The PPP / PPPoE module is arranged between an Ethernet data link layer and an IP layer of a TCP / IP protocol stack. The module is communicated with the Ethernet data link layer and the IP layer and a user process by the corresponding interface, the PPP link is set up and maintained according to the parameters collocated by the user process. In the invention, the PPP / PPPoE protocol is realized by the PPP / PPPoE module and the user process starts the PPP / PPPoE module. After finishing the PPPoE discovering phase, the module loads the PPP protocol in a PPPoE conversation phase, sets up and maintains the PPP / PPPoE link. The user process communicates on the link. The PPP protocol is easily and effectively realized on the Ethernet.

Description

technical field [0001] The invention belongs to the field of broadband access, in particular to a device and method for establishing a PPP link based on the TCP / IP protocol. Background technique [0002] Point-to-Point Protocol (PPP) is a link layer protocol designed for simple links such as transmitting data packets between peer units. This link provides full-duplex operation and delivers packets in order. It is mainly used to establish a point-to-point connection to send data through dial-up or leased line, making it a common solution for simple connection between various hosts, bridges and routers. Using Ethernet (Ethernet) resources, running PPP on the Ethernet to perform user authentication access is called PPPoE. PPPoE not only protects the user's Ethernet resources, but also fulfills the ADSL access requirements. It is currently the most widely used technical standard in ADSL access methods. [0003] PPPoE has two phases: Discovery and Session. In the discovery st...
