Route Server
A physical device that runs one or more network layer routing pr otocols, 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 comput ation.
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 t able 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 observa tion
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.
