Abstract

The invention discloses a communication method, a communication system and the virtual client terminal equipment and relates to the Internet field. In the IPv4 to IPv6 transition network environment, communication between a user terminal and a vCPE can be realized through an IPv4 protocol, switching between IPv4 and IPv6 can be realized through the vCPE which is taken as an agent gateway, so not only can the IPv4 function and the IPv6 function be supported, but also requirements of the related user side equipment for the IPv6 supporting capabilities can be reduced, and the related user side equipment such as the user terminal, CPE, BRAS, and so on, are supposed to support only the IPv4 protocol and are not supposed to support various IPv6 transition technologies.

Description

technical field

[0001] The invention relates to the field of the Internet, in particular to a communication method, a communication system and virtual client terminal equipment. Background technique

[0002] In the transition network environment from IPv4 to IPv6, the solution that is currently attracting attention is vCPE (virtual customer terminal equipment), that is, at the operator controllable level, such as BRAS (Broadband Remote Access Server, broadband remote access server) layer, for CPE (Customer Premise Equipment , client terminal equipment) functions are virtualized.

[0003] figure 1 It is a schematic diagram of an existing vCPE solution. refer to figure 1 , in order to support both IPv4 and IPv6 functions, user-side related equipment such as user terminals, CPE, and BRAS need to support both IPv4 and IPv6 protocols. Support capabilities are spotty, hindering network migration. In addition, user terminals use DHCP (Dynamic Host Configuration Protocol) / DHCPv...
