  4. Equal-cost multi-path routing - Wikipedia

    en.wikipedia.org/wiki/Equal-cost_multi-path_routing

    Equal-cost multi-path routing (ECMP) is a routing strategy where packet forwarding to a single destination can occur over multiple best paths with equal routing priority. Multi-path routing can be used in conjunction with most routing protocols because it is a per-hop local decision made independently at each router.

  5. IP routing - Wikipedia

    en.wikipedia.org/wiki/IP_routing

    In order to achieve a successful transfer of data, the algorithm uses a routing table to select a next-hop router as the next destination for a datagram. The IP address of the selected router is known as the next-hop address. [1] The IP forwarding algorithm states: [2] Given a destination IP address, D, and network prefix, N:

  6. Routing table - Wikipedia

    The primary function of a router is to forward a packet toward its destination network, which is the destination IP address of the packet. To do this, a router needs to search the routing information stored in its routing table. The routing table contains network/next hop associations. These associations tell a router that a particular ...
