什么是承载网络(carrier network) 承载网络的定义 已有4人参与

查了很多中文文献，都没有给出具体的定义，而且大部分跟承载网络有关的论文都是电信运营商的员工发表的，且大部分跟运行商网络建设有关。 查找外文资料，发现一个比较靠谱的定义（或者描述），虽然这个不是在文献中出现的，但是个人感觉已经可以帮助理解承载网络的定义了。 Part of the Telecom glossary: A carrier network is the proprietary network infrastructure belonging to atelecommunications service provider such as Verizon, AT&T or Sprint. Telecom carriers are authorized by regulatory agencies to operate telecommunications systems. Carrier networks are made up of large, complex configurations of hardware, interconnected to provide communications services to people spread over large geographic areas. Specific device types served by a carrier network include telephony equipment, CATV(community access television) receivers, satellite television receivers, mobile computingdevices, PCs (personal computers), and certain specialized items such as medical and surveillance equipment. Carrier networks distribute massive quantities of data over great distances. The long-distance signal-conveying medium in a carrier network is sometimes called the backbone. Most of the backbone is built around fiber optics, although some portions of some networks still employ "copper" (cable). Internet service to individual end users can take place through fiber optics (in the best-case scenario) although cable, wireless, and satellite Internetmodes are more common. In rural areas, some end users rely on twisted pair telephone lines for their Internet access. 原文链接 http://whatis.techtarget.com/definition/carrier-network 另外：http://www.imweihai.com http://bbs.imweihai.com |
