天津是我国通信网络和信息产业较为发达的地区之一,目前,天津中国电信的数据通信网已覆盖了整个天津地区。天津地区的金桥网络也正处于进一步完善阶段,很快会发展成为一个较大的信息服务网络。此外,许多专用网络也正在建设之中,可以预见随着这些网络的不断完善和发展,今后必将成为天津信息港工程的重要基石。然而,目前天津地区的几大网络均为独立系统,各自都有通往Internet的国际通道,由于它们之间互不相连,相互间的信息交换都是通过国外的Internet交换中心(均经由美国Internet)进行的,这样大大增加了各网络国际出口的压力,使得整个网络的信息传输速度减慢、性能下降,对于一些要求通信速率较高的应用来说,已无法正常工作。因此,从网络发展的角度出发,必须尽早解决这种不合理的问题。解决这个问题的一个主要方法就是将
Tianjin is one of the more developed regions in China for its communications network and information industry. At present, the data communications network of China Telecom in Tianjin has covered the whole of Tianjin. Tianjin Jinqiao network is also in the further improvement stage, will soon develop into a larger information service network. In addition, many private networks are under construction. It is foreseeable that as these networks continue to improve and develop, they will surely become an important cornerstone of Tianjin Port of Information in the future. However, at present, several major networks in Tianjin are independent systems and each has its own international gateway to the Internet. Because they are not connected to each other, information exchange between them is conducted through foreign Internet exchange centers ), Which greatly increased the pressure on the international export of each network, making the entire network slowed down the transmission of information, performance degradation, for some applications require higher communication speed, has been unable to work properly. Therefore, from the perspective of network development, such unreasonable problems must be solved as soon as possible. One of the main ways to solve this problem is to be
