YD/T 2297-2011 in English

本标准规定了在宽带接入汇聚网中基于TR-101架构的IPv6用户会话和IPv6会话组的概念，定义了相关网元的技术要求。本标准还规定了在IPv6用户会话周期中，通过用例、机制、协议和相关的交互来保证IPv6用户会话的实现及针对IPv6流所需要采取的流量特殊处理。本标准中涉及的IPv6流的分类仅限于在IP网络层和传输协议层。
本标准适用于IPv6网络或在宽带接入时使用IPv6的情况。

Scope

This standard specifies the concepts of IPv6 user sessions and IPv6 session groups based on the TR-101 architecture in broadband access aggregation networks, and defines the technical requirements for related network elements. This standard also stipulates the implementation of IPv6 user sessions through use cases, mechanisms, protocols and related interactions during the IPv6 user session cycle and the special traffic processing required for IPv6 flows. The classification of IPv6 flows involved in this standard is limited to the IP network layer and transport protocol layer. The IPv6 user session cycle includes the following series of possible stages:
　•Detection and creation of IPv6 user sessions;
　•Application and change of IPv6 user session policies, including authentication, authorization and accounting, monitoring, session groups, etc.;
　•IPv6 user session Resume and terminate. This standard applies to IPv6 networks or when IPv6 is used in broadband access. Unless explicitly stated in this standard, IP protocol, PPP protocol and DHCP protocol versions all refer to version 6.
