|  AcerRouter 700 User Guideprivate/public networkPlease see Single IP AddressRouterAn intelligent, multi-network interface device that will forward a packet receivedfrom one interface to another. When a packet is received, its destination networkaddress 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 hopcloser to the destination.)Routing ProtocolA 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 TableA router relies on a routing table to determine where to forward a received packet.The routing table normally contains, for each destination network, the networkaddress 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 periodicallyexchanged and kept up-to-date. If a router fails, any of the networks reachable onlythrough this router will become unreachable. The routing table will reflect suchfailure either by (1) a router detecting the failure, and broadcasting the failure toeveryone else, or (2) when the corresponding routing entries in the routing table ageout (no update from other routers for a long time).RSVPThe ReSerVation Protocol, a protocol that is used to simulate QOS (Quality OfService) negotiation in a fundamentally non-multimedia-capable network, such asframe relay, in order to support multimedia applications.Single IP AddressThis is a feature that allows the local network to be divided into a public sub-networkand a private sub-network. All devices in the private sub-network will be representedby the router to the WAN side (outside) as one single IP address, and therefore iseffectively “hidden” and not accessible from the outside, although such devices canstill access the outside at will. All devices in the public sub-network will conform tothe standard IP address scheme, and will be accessible from the outside as usual.Static RouteA route in the routing table that is manually configured rather then learned throughrouting table exchanges. |
