Description

Technical Field

[0001] The disclosed embodiments relate to the field of automatic testing technology, and in particular, to an automatic testing system and method for metropolitan area network access equipment. Background Art

[0002] With the development and progress of communication technology, the number of Internet Protocol version 6 (IPv6) users in the entire network has exploded. However, fixed home networks will gradually become a bottleneck restricting the development of IPv6. Compared with mobile network users, fixed-line broadband home users have access methods that involve network terminal devices such as home gateways and home routers. These devices have differences in their own support for IPv6, applicability to home networking, and network address allocation methods. Each of these links will determine whether users can ultimately use the IPv6 network. It can be seen that the home network, as the "last mile" of network access, has become an important link in determining the scale of IPv6 users and traffic.

[0003] When accessing the MAN, there is a lack of testing methods for IPv6 function support, Internet Protocol version 4 (IPv4) / IPv6 dual-stack network compatibility, and consistency of IPv6 network address allocation. On the other hand, MAN access devices rely heavily on the existing network access environment for function and performance testing, and lack the ability to simulate related network topologies.
