A router may create or maintain a table of the available routes and their conditions and use this information along with distance and cost algorithms to determine the best route for a given packet.

IP addresses route a packet across the whole global Internet, while MAC addresses help the packet make the small, local hop between hardware devices.
IP地址在整个全球因特网中路由数据包，而MAC地址则帮助数据包在两个硬件设备间做狭小的局部的传递。
If the route table lookup shows that the packet is destined for a non-local subnet, the router forwards the packet to the next-hop router using the next-hop router's MAC address.
如果查找路由表显示包的目的地不在本地子网，路由器就利用下一跳路由器的MAC地址把包转发给下一跳路由器。

If a route is not found, the packet is sent to the source host's default gateway, also called a router.
如果找不到路径，数据包就被送往发送端主机的默认网关，有时也称为路由器。
When mobile host changes its position, the route of the flow changes, which may causes the change of packet delay as routers on the new route may gain different path length and queuing delay.
当移动主机位置改变时，数据流的路由改变了，那么分组延迟可能会改变，因为新的路由上的路由器会获得不同的路径长度和不同的排队延迟。
Simulation demonstrated that the algorithm could dynamic adjust the route which can make the product of packet delay and energy consumption of routing path to be minimization in AD hoc networks.
仿真表明，该算法可以动态调整网络路由路径，使所选路径的平均分组时延与分组能量消耗乘积达到最小。
If the route table lookup shows that the packet is destined for a nonlocal subnet, the router forwards the packet to the next-hop router using the next-hop router's MAC address.
如果查找路由表显示包的目的地不在本地子网，路由器就利用下一跳路由器的MAC地址把包转发给下一跳路由器。
Variations in packet arrival time, called jitter, can occur because of network congestion, timing drift, or route changes.
包到达时间的变化，称作抖动，将会由于网络拥塞，定时漂移或路由变更而产生。
Therefore the mobility and the packet delivery are key factors to the research of route optimization.
切换频率和数据报传送频率是路由优化研究要考虑的两个重要因素。
The route selection strategy guarantee the node will forward packet to travel with the best link, and no circle occurs.
路由选择算法保证了节点发送数据沿着最好的链路进行，并且不会形成环路。
External packet filters and IP Layer-4 and Layer-7 switches can also handle and route client requests.
外部数据包过滤器以及IP的第4层和第7层之间的转换也可以处理和发送客户机请求。
