The Internet Protocol (IP) is a series of specifications set out by various standards organizations, primarily the Internet Engineering Task Force (IETF). “network-aware” and make sophisticated decisions about internetworking based on current conditions in the network, including (but not limited to) route availability, route congestion, and opportunities for multicast (the delivery of a message or information from one source to multiple destinations in a single transmission). Each router utilizes a continuously updated routing table that
gives the routers a real-time updated network “map” that allows the routers to work in parallel to manage the flow of IP packets within the network. The decisions that a router is able to make on specific traffic flows can add substantially to the manageability, efficiency, and scalability of a network.
