BGP --Border Gateway Protocol. The predominant interdomain routing protocol used in IP networks.
Border Gateway Protocol --See BGP.
FIB --Forwarding Information Base. A table that contains a copy of the forwarding information in the IP routing table.
Forwarding Information Base --See FIB.
label --A short, fixed-length identifier that tells switching nodes how the data (packets or cells) should be forwarded.
label binding --An association between a label and a set of packets, which can be advertised to neighbors so that a label switched path can be established.
Label Distribution Protocol --See LDP.
Label Forwarding Information Base --See LFIB.
label imposition --The act of putting the first label on a packet.
label switching router --See LSR.
LDP --Label Distribution Protocol. The protocol that supports MPLS hop-by-hop forwarding by distributing bindings between labels and network prefixes.
LFIB --Label Forwarding Information Base. A data structure in which destinations and incoming labels are associated with outgoing interfaces and labels.
LSR --label switching router. A Layer 3 router that forwards a packet based on the value of an identifier encapsulated in the packet.
MPLS --Multiprotocol Label Switching. An industry standard on which label switching is based.
MPLS hop-by-hop forwarding --The forwarding of packets along normally routed paths using MPLS forwarding mechanisms.
Multiprotocol Label Switching --See MPLS.
Resource Reservation Protocol --See RSVP.
RIB --Routing Information Base. A common database containing all the routing protocols running on a router.
Routing Information Base --See RIB.
RSVP --Resource Reservation Protocol. A protocol for reserving network resources to provide quality of service guarantees to application flows.
traffic engineering --Techniques and processes used to cause routed traffic to travel through the network on a path other than the one that would have been chosen if standard routing methods were used.
Virtual Private Network --See VPN.
VPN --Virtual Private Network. A network that enables IP traffic to use tunneling to travel securely over a public TCP/IP network.
