IP routing (original) (raw)
Dans le domaine des réseaux, le routage IP désigne l'ensemble des méthodes de l'Internet Protocol utilisées pour router un paquet à travers un réseau. Par extension, cela désigne également l’ensemble des politiques internationales sur la configuration des réseaux, notamment internet.

| dbo:abstract | IP routing is the application of routing methodologies to IP networks. This involves not only protocols and technologies but includes the policies of the worldwide organization and configuration of Internet infrastructure. In each IP network node, IP routing involves the determination of a suitable path for a network packet from a source to its destination in an IP network. The process uses static configuration rules or dynamically obtained from routing protocols to select specific packet forwarding methods to direct traffic to the next available intermediate network node one hop closer to the desired final destination, a total path potentially spanning multiple computer networks. Networks are separated from each other by specialized hosts, called gateways or routers with specialized software support optimized for routing. IP forwarding algorithms in most routing software determine a route through a shortest path algorithm. In routers, packets arriving at an interface are examined for source and destination addressing and queued to the appropriate outgoing interface according to their destination address and a set of rules and performance metrics. Rules are encoded in a routing table that contains entries for all interfaces and their connected networks. If no rule satisfies the requirements for a network packet, it is forwarded to a default route. Routing tables are maintained either manually by a network administrator, or updated dynamically by a routing protocol. A routing protocol specifies how routers communicate and share information about the topology of the network, and the capabilities of each routing node. Different protocols are often used for different topologies or different application areas. For example, the Open Shortest Path First (OSPF) protocol is generally used within an enterprise and the Border Gateway Protocol (BGP) is used on a global scale. BGP is the de facto standard for worldwide Internet routing.

(fr) 操作系统拥有 IP转发（英語：IP forwarding）功能，意味着该系统能接收从接口传送进来的 网络数据包（英語：network packets），如果识别到该数据包不用于该系统自身，那么系统将会将该网络数据包传送到另外一个网络去，用恰当地方式转发该数据包。 一个典型的场景是需要去搭建一个路由器以连接两个不同网络。 (zh) |
