Abstract:

Ethernet access is a primary way to implement broadband access. An integrated software system of broadband access switch should include the device driver, configuration interface, applications and network management, etc. The VLAN technology in access switch can utilize effectively the bandwidth and enhance the data safety. This paper first introduces the architecture of our access switch, and then provides the framework of the software system. We will emphasis on the design and implementation of the major modules in the software system of our broadband access switch.

Key words: broadband access, VLAN, IGMP, Spanning Tree
