目前,我国Internet取得了突飞猛进的发展,已形成ChinaNet、CERNet等几大网络,如何实现这些网络的互联是人们关注与思考的重要课题。最近,第一家全国范围内的Internet交换中心(NetworkAccess Point,NAP)在北京成立,它使网络互联问题得到了效解决。据了解,该NAP使我国主要Internet间互联带宽由原来不到10Mbps大幅度提高到100Mbps以上。那么,NAP到底是什么呢?为提高不同ISP之间的互访速率,节约有限的骨干网络资源,以及为国内或本地区的各个网络实现互通,NAP将提供一个快速的交换通道。
At present, China’s Internet has made rapid development. ChinaNet and CERNet have formed several major networks. How to realize the interconnection of these networks is an important issue that people pay attention to and think about. Recently, the first nationwide Internet Access Point (NAP) was established in Beijing, which solved the interconnection problem. It is understood that the NAP Internet connectivity in China’s main Internet bandwidth from less than 10Mbps substantially increased to 100Mbps above. So, what exactly is NAP? In order to increase the speed of mutual visits between different ISPs, save limited backbone network resources, and provide intercommunication for various networks in China or in the region, NAP will provide a fast exchange channel.
