Resolvent of Two Connections to CERnet and ChinaNet for Campus Network

校园网双出口方案探讨

CHINANET Architecture And Access Modes

CHINANET网络构成及接入方式

Because of the bandwidth bottle-neck between CHINANET and CERNET , the public network can 't access campus network at high speed .

由于CHINANET和CERNET之间的带宽瓶颈，限制了公网访问校园网的速度。

These forward-looking statements are based on ChinaNet 's current expectations and beliefs concerning future developments and their potential effects on the company .

这些前瞻性声明基于当前的对于未来中网在线的发展和对公司预期及信心的潜在影响。

The data and multimedia communication networks in service in Hubei province includes PSPDN , DDN , CHINANET and the public multimedia network .

湖北省已开通运行的数据及多媒体通信网有：分组交换网、数字数据网、CHINANET及中国公众多媒体通信网等。

The Bottleneck of bandwidth between CERNET and ChinaNet is greatly restricted to user of CERNET in speed .

由于教育网和公网的瓶颈问题，给教育网用户上公网受到很大的限制。

There can be no assurance that future developments affecting ChinaNet will be those anticipated by ChinaNet .

我们不能确保中网未来新产品是否能和我们预期的吻合。

According to this characteristic , we ask to a same rapid speed to visit CERNET and ChinaNet , which is the double export issue .

在省域网的建设中，我们希望解决这一问题，达到访问公网和教育网同样的快速的目标，于是我们采用了双出口。

The paper introduces briefly the current situation of CHINANET development , analyses its architecture and access modes and describes the basic scheme about future roaming in the whole network .

本文简介了CHINANET的发展现状，较详尽地剖析了它的网络结构和接入方式，并就未来全网漫游的原则方案进行了基本阐述。

Internet in China is primarily consisted of four networks at present : ChinaNET , CERNET , ChinaGBN and CSTNET .

目前中国的互联网主要由ChinaNET、CERNET、ChinaGBN、CSTNET等网络组成。

CHINANET and the multimedia network will surely be the future developing focus , Hubei broadband multimedia communication network will be based on ATM and linked to the national backbone network .

CHINANET及中国公众多媒体网无疑是今后发展的重点。湖北省宽带多媒体通信网将基于ATM技术，以便与国家骨干网相衔接。

CERNET users have installed the second line to connect with Internet so as to reduce the cost of CERNET and to widen the bandwidth for CHINANET .

教育科研网（CERNET）用户可通过加装第二条线路连接Internet，以降低使用CERNET的费用，加大访问公网的带宽。

The paper discusses implementation and configuration measures of route about campus network interconnecting and connecting to Internet by CERNET and CHINANET . Also introduces how to perform data distributary , access list and policy based routing in router .

对采用CERNET和CHINANET两条链路接入Internet的路由配置方法及在路由器上实现数据分流、访问列表和策略路由作了讨论。

The virtual private network ( VPN ) is a new service launched over the CHINANET in recent years , consisting of virtual private dial-up network ( VPDN ), IPSec-based VPN and MPLS-based VPN services to meet the demands of various customers .

虚拟专网是中国宽带互联网（CHINANET）近年来发展的新业务，主要有虚拟专有拨号网络（VPDN）业务、基于IPSec的VPN业务和基于MPLS的VPN业务，来满足不同用户的需求。

CERNET users are always affected by the communication bottleneck between CERNET and ChinaNET . Even if the users have access lines for the two networks at the same time , they also have to inconveniently switch the connection between the two networks by hand .

教育网接入用户长期受到ChinaNET和CERNET之间通信瓶颈的影响，即使同时拥有两个网络的接入线路，用户也需要靠手动切换来选择网络，很不方便。
