路由器的一个重要功能是路由的管理和维护，目前具有一定规模的网络都采用动态的路由协议，常用的有：RIP、EIGRP、OSPF、IS - IS、BGP等。
A major function of the router's routing management and maintenance, now has a certain scale of network is a dynamic routing protocol, the commonly used are: RIP, EIGRP, OSPF, is as-is, BGP, etc.
OSPF协议是一种动态路由协议，它利用内部的链路状态数据库来维护和计算路由，它的路由算法是本协议的关键部分。
The OSPF protocol is a dynamic routing protocol, which uses of the link state database to maintain and calculate routings. Its routing algorithm is the most important part.
在动态路由，设备自动建立和维护路由表的使用路由协议交换信息的周围的网络拓扑。
In dynamic routing, devices build and maintain their routing tables automatically by using routing protocols to exchange information about the surrounding network topology.
基于位置的路由协议由于不必维护明确的路由，在这种高度动态的网络中具有很好的扩展性。
The position based routing protocols have scalability in the dynamic networks because they needn't maintain explicit routings.
由于不必维护明确的路由，基于位置的路由协议即使在网络高度动态的情况下也具有很好的扩展性。
The position based routing protocols are adaptable to the dynamic mobile Ad hoc networks due to not maintain explicit routing, and this is an advantage in the topology changing frequently MANET.
该协议在路由发现以后，以所发现的路径做为基础路径，在其周围一定跳数范围内维护了一个路径修复区域。
Focusing on the AODV routing repair strategy and based on the hop count on the base path and the destination node, HAODV maintenances a repair area around the base path within certain number of hops.
路由协议通常使用较多的短报文进行路由的产生和维护，路由效率较低，不适合在超短波信道上运行。
Routing protocol usually use short packets to find out and maintain the routing information, which leads to the low efficiency. Thus it dose not fit the channel.
改进内容为：（1）借鉴DSR协议的特点，使其路由表维护多条路由记录；
The improvement is:(1)Multi-records are maintained in the routing table referring to the advantages of DSR protocol;
OSPF协议是一种动态路由协议 ，它利用内部的链路状态数据库来维护和计算路由 ，它的路由算法是本协议的关键部分 。
The OSPF protocol is a dynamic routing protocol, which uses of the link state database to maintain and calculate routings.
