Now the backbone network of ddn ifl our coufltry has covered over 30 big cit 1es of china , i . e . most users may efljoy the services of ddn 目前我国ddn骨干网已经覆盖到全国30多个大城市，也就是说全国的大部分用户都可以使用ddn业务。
For example , a gigabit ethernet lan could be used to support high - speed clustering or implement a high - speed internet backbone between remote networks 比如说，千兆以太局域网可以用来支持高速群集，或实现远程网络之间的高速internet骨干网。
" the fast ethernet backbone has improved the reaction time of our network , and it has been able to maintain that even as our user community grows , " he said 他说： “快速以太骨干网改进了网络的响应时间，甚至在用户群体增加时仍然能保持响应时间。 ”
The wide - band accessing technology can allow the users make best use of the main meshwork earring capacity , and ultimately provide the high speed access to network for users 宽带接入技术让用户充分利用骨干网的承载能力，最终实现用户到网络的高速接入。
When there is a backbone ip network in the province , the gsn , a generic term for both the sgsn and the ggsn , can serve as an access node to the backbone ip network 当省内有ip骨干网络时， gsn （ gprs服务节点与关口节点的统称）节点作为ip骨干网的接入节点。
Abstract : this paper deals with the principles and realization of the third - level interchange routing technique , and presents the design considerations of the network 文摘:文章着重描述了第三层交换式路由技术原理和实现方法，并给出建设企业骨干网的设计思想。
If there is a backbone ip network , the gsn nodes are directly connected to it . if not , these backbone nodes can be connected on a pppfratm basis 当省内有ip骨干网时， gsn节点等直接连接到ip骨干网上，当没有ip骨干网时，可以用pppfratm等方式将各骨干节点连接起来。
Our new router and backbone is upgraded which are capable to handle multiple separate international connections and fulfill high traffic demand of nowadays internet market 有关工程将骨干网路backbone升级至光纤骨干optical fiber ，可处理更大量的外国连接及应付日益增加的网络需求。
This also results in that several traditional communication networks converge into one uniform ip network to provide digital , video and voice services , which has been widely adopted in back - bone networks 目前骨干网已经采用统一的ip网络，而接入网则有多种类型，流行的有xdsl 、 cablemodem 、以太网接入等。
