Internet access method of network card and network card

Abstract

The invention provides an internet connection method of a network card and a network card. The method comprises the following steps: the network card acquires an IP address allocated by a base station after being connected with a client; the network card acquires an IP mask and a gateway address according to the IP address; the network card sends the IP address, the IP mask and the gateway address to the client after receiving an IP address allocation request from the client; and the network card returns a physical address to the client after receiving a physical address acquisition request from the client, so that the client can surf the internet according to the network card according to the IP address, the IP mask, the gateway address and the physical address. The technical scheme for internet connection, provided by the invention, can support various usage scenarios, and the internet connection way is very flexible, simple to implement and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a network access method of a network card and the network card. Background technique [0002] At present, the LTE network card uses Point-to-Point Protocol over Ethernet (PPPoE) dial-up on Ethernet to access the Internet. PPPoE dial-up Internet access is to encapsulate the Point-to-point protocol (PPP) in the Ethernet A network tunneling protocol in the (Ethernet) framework, which enables Ethernet users to connect to a remote access device through a simple bridge device. Through the PPPoE protocol, the remote access device can control and charge each access user. [0003] The workflow of the PPP protocol includes two stages of discovery and session. The discovery stage is stateless, and the purpose is to obtain the Media Access Control (MAC) address of the Ethernet of the PPPoE terminal and establish a unique PPPoE Session-ID. . In the discovery phase, based on the topol...

Problems solved by technology

[0005] In the prior art, if users using the Windows XP system want to access the IPv6 network, they need to tunnel with the IPv6 network under the premise of installing the IPv6 protocol; specifically, a router or a personal computer (Personal Computer; PC ) as a gateway to forward packets to the IPv6 network; and in the process of PPPoE dial-up Internet access, because it is a point-to-point connection, there is no corresponding gateway to forward packets. When users use PPPoE dial-up Internet access under the Windows XP system, they cannot access the IPv6 network , so the usage scenarios of PPPoE dial-up Internet access in the prior art are limited, and the Internet access method is not flexible
