Ip fast path4/16/2023 IP: The Internet Protocol (IP) specifies the origin and destination for each data packet. The following protocols help data packets find their way across the Internet: A routing protocol is a protocol used for identifying or announcing network paths. In networking, a protocol is a standardized way of formatting data so that any connected computer can understand the data. *Packet headers are small bundles of data attached to packets that provide useful information, including where the packet is coming from and where it is headed, like the packing slip stamped on the outside of a mail parcel. But for medium-sized and large networks, dynamic routing is much more efficient. They also make this determination based on how long it takes packets to reach their destination - similar to the way Google Maps, Waze, and other GPS services determine the best driving routes based on past driving performance and current driving conditions.ĭynamic routing requires more computing power, which is why smaller networks may rely on static routing. Dynamic routers use various routing protocols (see below) to determine the shortest and fastest paths. This essentially sets in stone the routes data packets take across the network, unless the administrator manually updates the tables.ĭynamic routing tables update automatically. A network administrator manually sets up static routing tables. Routing tables can either be static or dynamic. As a packet travels to its destination, it may be routed several times by different routers. Routers do this millions of times a second with millions of packets. It then determines where to route the packet based on information in its routing tables. Routers work in the following way: when a router receives a packet, it reads the headers* of the packet to see its intended destination, like the way a train conductor may check a passenger's tickets to determine which train they should go on. Routing tables are like that, but for network paths rather than trains. Think of train timetables, which train passengers consult to decide which train to catch. A routing table records the paths that packets should take to reach every destination that the router is responsible for. Routers refer to internal routing tables to make decisions about how to route packets along network paths. These are the kinds of choices network routers constantly make. For a data packet to get from Computer A to Computer B, should it pass through networks 1, 3, and 5 or networks 2 and 4? The packet will take a shorter path through networks 2 and 4, but networks 1, 3, and 5 might be faster at forwarding packets than 2 and 4. These Internet routing decisions are made by specialized pieces of network hardware called routers.Ĭonsider the image below. In packet-switching networks, such as the Internet, routing selects the paths for Internet Protocol (IP) packets to travel from their origin to their destination. The principles of routing can apply to any type of network, from telephone networks to public transportation. Network routing is the process of selecting a path across one or more networks.
