R Glossary

Route Server

A physical device that runs one or more network layer routing protocols, and which uses a route query protocol in order to provide network layer routing forwarding descriptions to clients.

Router

A physical device that is capable of forwarding packets based on network layer information and that also participates in running one or more network layer routing protocols.

Routing Computation

The process of applying a mathematical algorithm to a topology database to compute routes. There are many types of routing computations that may be used. The Djikstra algorithm is one particular example of a possible routing computation.

Routing Constraint

A generic term that refers to either a topology constraint or a path constraint.

Routing Information Protocol

Based on distance-vector algorithms that measure the shortest path between two points on a network, based on the addresses of the originating and destiantion devices. The shortest path is determined by the number of “hops” between those points. Each router maintains a routing table, or routing database, of known addresses and routes; each router periodically broadcasts the contents of its table to neighboring routers in order that the entire network can maintain a synchronized

database.1

Routing Protocol

A general term indicating a protocol run between routers and/or route servers in order to exchange information used to allow computation of routes. The result of the routing computation will be one or more forwarding descriptions.

RS

Remote single-layer (Test Method): An abstract test method in which the upper tester is within the system under test and there is a point of control and observation at the upper service boundary of the Implementation Under Test (IUT) for testing one protocol layer. Test events are specified in terms of the abstract service primitives (ASP) and/or protocol data units at the lower tester PCO.
