Glossary
- Frame Relay
- A high-speed WAN link that uses point-to-point virtual circuits. A virtual circuit is a logical connection between two sites.
- A Frame Relay network consists of a backbone, made up of FR switches, that provides the service. Typically, a public Frame Relay supplier offers the Frame Relay service. The router acts as the device that connects your LANs to the Frame Relay WAN.
- IP (Internet Protocol)
- A set of protocols that enables interconnected networks to function as a single system. This protocol defines the IP datagram as the unit of information passed across an internet. It provides the basis for connectionless, best-effort packet delivery service, with no guarantee that the packet reaches its destination; reliability is left to a transport protocol, such as TCP.
- IPX (Internet Packet Exchange)
- A Novell NetWare protocol that transfers information between networks connected by physical media.
- LAN (Local Area Network)
- Any physical network technology that operates at high speed over short distances. For example, Ethernet.
- RIP (Routing Information Protocol)
- A protocol that allows routers to exchange information about destinations for computing routes throughout the network. Does not alter IP packets and routes them based on destination address only.
- static route
- A route that is defined (that is, manually entered) by you in a routing table.
- subnet mask
- An address mask that specifies which parts of an IP address identify a network and which parts identify a host. Subnet masks allow a site with multiple physical LAN segments to use a single IP network number.
- WAN (Wide Area Network)
- Any physical network technology that spans large geographic distances. For example, the Internet.
