Please see Single IP Address
Router
An intelligent, multi-network interface device that will forward a packet received
from one interface to another. When a packet is received, its destination network
address is checked against the routing table, based on which it determines which next-
hop router to forward the packet to. (The next-hop router should in theory be one hop
closer to the destination.)
Routing Protocol
A protocol that is used to exchange its routing table with all of its neighbor routers
(distance vector based), or all of the routers in the network (link state based).
Routing Table
A router relies on a routing table to determine where to forward a received packet.
The routing table normally contains, for each destination network, the network
address of the next hop router, the hop count to the destination, and aging count,
among other information.
The aging count is for information aging purposes: the routing table is periodically
exchanged and kept up-to-date. If a router fails, any of the networks reachable only
through this router will become unreachable. The routing table will reflect such
failure either by (1) a router detecting the failure, and broadcasting the failure to
everyone else, or (2) when the corresponding routing entries in the routing table age
out (no update from other routers for a long time).
RSVP
The ReSerVation Protocol, a protocol that is used to simulate QOS (Quality Of
Service) negotiation in a fundamentally non-multimedia-capable network, such as
frame relay, in order to support multimedia applications.
Single IP Address
This is a feature that allows the local network to be divided into a public sub-network
and a private sub-network. All devices in the private sub-network will be represented
by the router to the WAN side (outside) as one single IP address, and therefore is
effectively “hidden” and not accessible from the outside, although such devices can
still access the outside at will. All devices in the public sub-network will conform to
the standard IP address scheme, and will be accessible from the outside as usual.
Static Route
A route in the routing table that is manually configured rather then learned through
routing table exchanges.
