This paper first introduces the general problems met when building Broadband Community Access Network which supports Integrated Services, and then presents some solutions and achievements on multicast service, QoS provision, security, network accounting and billing. In the third section, this paper gives the architecture of a community network, which is a broadband access network based on high-speed switching Ethernet, and provides integrated services, such as digital TV, IP telephone, WWW, Email, and so on. This paper also gives an implementation of this broadband access system, which can afford the special requests of classified transfer, QoS and security, and at the same time provides the accounting and billing function. Lastly, this paper indicates the unfinished part of this broadband access system, and describes the future development.
