  2. Source routing - Wikipedia

    en.wikipedia.org/wiki/Source_routing

    In computer networking, source routing, also called path addressing, allows a sender of a data packet to partially or completely specify the route the packet takes through the network. [1] In contrast, in conventional routing , routers in the network determine the path incrementally based on the packet's destination.

  3. Internet Protocol Options - Wikipedia

    en.wikipedia.org/wiki/Internet_Protocol_Options

    Loose Source Routing is an IP option which can be used for address translation. LSR is also used to implement mobility in IP networks. [3] Loose source routing uses a source routing option in IP to record the set of routers a packet must visit. The destination of the packet is replaced with the next router the packet must visit.

  4. IP routing - Wikipedia

    en.wikipedia.org/wiki/IP_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.

  6. Protocol-Independent Multicast - Wikipedia

    en.wikipedia.org/wiki/Protocol-Independent_Multicast

    In SSM, an IP datagram is transmitted by a source S to an SSM destination address G, and receivers can receive this datagram by subscribing to channel (S,G). See informational RFC 3569. PIM-SM is commonly used in IPTV systems for routing multicast streams between VLANs, subnets or local area networks. [5]

  7. 0.0.0.0 - Wikipedia

    en.wikipedia.org/wiki/0.0.0.0

    This generally means that no intermediate routing hops are necessary because the system is directly connected to the destination. [9] The CIDR notation 0.0.0.0 / 0 defines an IP block containing all possible IP addresses. It is commonly used in routing to depict the default route as a destination subnet. It matches all addresses in the IPv4 ...

  8. Routing protocol - Wikipedia

    en.wikipedia.org/wiki/Routing_protocol

    Routing protocols, according to the OSI routing framework, are layer management protocols for the network layer, regardless of their transport mechanism: IS-IS runs on the data link layer (Layer 2) Open Shortest Path First (OSPF) is encapsulated in IP, but runs only on the IPv4 subnet, while the IPv6 version runs on the link using only link ...

  9. Default gateway - Wikipedia

    en.wikipedia.org/wiki/Default_gateway

    The IP-address could be 91.198.174.2. In this example, none of the internal routers know the route to that host, so they will forward the packet through router1's gateway or default route. [1] Every router on the packet's way to the destination will check whether the packet's destination IP-address matches any known network routes.
