Glossary

Adaptation capability: A property of a link interface that connects a particular data link to a transport node. Within GMPLS, this property characterizes the interface's ability to perform a nesting function; that is, to use a locally terminated LSP that belongs to one network layer as a data link for some other network layer(s).
All-pairs shortest path problem: The computational problem of finding the shortest paths between every pair of vertices in the TE network graph.
Alternative LSP: See also Recovery LSP.
Availability: The availability of a network or a network element is the probability that the network or network element can deliver some specified Quality of Service (QoS) at some point in time.

Backup Designated Router (BDR): A routing controller elected among neighbors in a multi-access network. The BDR is expected to assume the functions of the DR when it detects that the DR is non-functional. The BDR establishes routing adjacencies with each of the neighbors in the network.

See also Designated Router (DR).
Best disjoint paths: Two or more paths that have the smallest number of TE links, transport nodes, and SRLGs in common.

Command Line Interface (CLI): The basic management interface at which an operator can issue a series of text commands to control the managed device. The CLI may be run through a directly attached terminal, or over a remote access protocol such as Telnet.
Common Object Request Broker Architecture (CORBA): A network management technology that takes an object-oriented approach to management...
