北辰社区网络一期工程可为园区用户提供超过3600个信息点10/100Mbps以太网接入,在未来还将使用ADSL和CableModem等技术提供更广范围的高速接入服务。社区网络由双三角形型结构的骨干网络和楼内接入网络、Internet服务系统三部分构成。网络为分层的星型结构,并保留相应的冗余链路。它的特点是:用户接入带宽高。用户接入线路为10/100Mbps以太网,速度快、技术标准、接入成本低:技术设备先进成熟。骨干网采用千兆以太网技术,全部选用Cisco的网络产品;支持宽带多媒体应用功能。网络骨干带宽为2Gbps,一期用户接入网络带宽10/100Mbps:并且在全网提供不同的QoS机制保证多媒体信息服务质量;同时应用FEC、PortTrunking、GEC等多种技术提高网络带宽、负载通
The first phase of the Beichen Community Network can provide over 10,600 points of Ethernet 10/100 Mbps access to campus users. It will also provide a wider range of high-speed access services using technologies such as ADSL and CableModem in the future. The community network consists of a double triangle-shaped backbone network and an in-building access network and an Internet service system. The network is a layered star structure with the corresponding redundant links. Its features are: high user access bandwidth. User access lines for 10 / 100Mbps Ethernet, fast, technical standards, access to low cost: Advanced technology and equipment mature. Backbone network uses Gigabit Ethernet technology, all use Cisco’s network products; support for broadband multimedia applications. The backbone network bandwidth of 2Gbps, a user access network bandwidth 10 / 100Mbps: and in the whole network to provide different QoS mechanisms to ensure the quality of multimedia information services; at the same time using FEC, PortTrunking, GEC and other technologies to improve network bandwidth,
