    Provider edge router (PE): An MPLS-specific router in the network's access layer that interconnects with customer edge routers to provide layer 2 or layer 3 VPN services. [27] Customer edge router (CE): Located at the edge of the subscriber's network, it interconnects with the PE router for L2VPN services, or direct layer 3 IP hand-off in the ...

  3. Routing protocol - Wikipedia

    en.wikipedia.org/wiki/Routing_protocol

    Routers perform the traffic directing functions on the Internet; data packets are forwarded through the networks of the internet from router to router until they reach their destination computer. Routing algorithms determine the specific choice of route. Each router has a prior knowledge only of networks attached to it directly.

  4. Routing - Wikipedia

    en.wikipedia.org/wiki/Routing

    Packet forwarding is the transit of network packets from one network interface to another. Intermediate nodes are typically network hardware devices such as routers, gateways, firewalls, or switches. General-purpose computers also forward packets and perform routing, although they have no specially optimized hardware for the task.

    en.wikipedia.org/wiki/Wireless_router

    Some wireless routers have one or two USB ports. These can be used to connect printer or desktop or mobile external hard disk drive to be used as a shared resource on the network. [2] A USB port may also be used for connecting mobile broadband modem, [3] aside from connecting the wireless router to an Ethernet with xDSL or cable modem. A mobile ...

    eth0 is the interface name of the network interface card representing an Ethernet port. ppp0 is a PPPoE interface, which is configured as the default route in this example. A default route is recognized by the destination 0.0.0.0 and the flag G. A network router is identified by the network mask 255.255.255.255 and the flag H.

  7. Network layer - Wikipedia

    en.wikipedia.org/wiki/Network_layer

    The network layer provides the means of transferring variable-length network packets from a source to a destination host via one or more networks. Within the service layering semantics of the OSI (Open Systems Interconnection) network architecture, the network layer responds to service requests from the transport layer and issues service requests to the data link layer.

  9. Multiprotocol Label Switching - Wikipedia

    en.wikipedia.org/wiki/Multiprotocol_Label_Switching

    An MPLS router that performs routing based only on the label is called a label switch router (LSR) or transit router. This is a type of router located in the middle of an MPLS network. It is responsible for switching the labels used to route packets.
