浙江省电信公司是国内规模最大的电信公司之一,在宽带建设在全国兴起之后,浙江省电信做了很多调研;并组织国内外多家知名的网络厂家进行宽带技术交流。最终经过多方专家的评选,浙江电信选择“光纤+以太网接入”方式做为其主要的接入方式;用户认证采用 PPPOE 的方式。并且计划在2001年到2002提供30万以上的用户接入。由于浙江省采用“光纤+以太网接入”方式,并且认证采用 PPPOE 方式,这就要求宽带接入汇聚层设备、接入层设备采用二层设备,可以支持 DHCP,支持 IGMP等。通过考察,浙江电信发现,随着电信宽带建设的深入展开宽带接入过程中的一系列问题也接踵而来。具体表现如下:
Zhejiang Telecom is one of the largest telecom companies in China. After the rise of broadband construction in the whole country, Zhejiang Telecom made a lot of research and organized many well-known domestic and foreign network manufacturers to exchange broadband technologies. After the final selection by many experts, Zhejiang Telecom chose “fiber + Ethernet access ” as its main access method; user authentication using PPPOE way. And plans from 2001 to 2002 to provide more than 300,000 users access. As Zhejiang adopts “fiber + Ethernet access ” mode, and the authentication uses PPPOE mode, which requires broadband access convergence layer equipment, access layer equipment using Layer 2 devices that can support DHCP, support for IGMP and so on. Through investigation, Zhejiang Telecom found that with the development of telecom broadband in-depth development of broadband access in the course of a series of problems ensued. Specific performance is as follows:
