|---|
| Autonomous System | A collection of networks under common administration sharing a common routing strategy. Routing Domain |
| Bandwidth | Difference between highest and lowest frequencies available for network signals. |
| Border Gateway Protocol | Interdomain routing protocol that replaces Exterior Gateway Protocol (EGP). |
| Convergence | Speed and Abililty |
| Cost | Arbitraty Value |
| Delay | Time between sender and first response. |
| Dynamic Routing | Automatic Adjustment |
| Exterior Protocol | Used between networks that do not share a common administration. |
| Flash Update | Sending an update sooner than the standard update periodic update interval. |
| Gateway of Last Resort | Router to which all unroutable packets are sent. |
| Holddown | IGRP feature that rejects new routes for the same destination for some period of time. |
| hop | Passage of data packet between two network nodes. |
| hop count | Routing metric used to measure distance between a source and a destination. RIP uses it. |
| Interior Protocol | Used for routing networks that are under a common network administration. |
| IGRP | Developed by CISCO to address teh problems with routing in large networks. |
| Load | Amount of activity on a network resource. |
| Metric | Measurement |
| MTU | Maximum packet size, in bytes, that a particular interface can handle. |
| Multiprotocol Routing | Routing - router delivers pakcets from several routed protocols, such as TCP/IP and IPX, over the same data links. |
| Next-hop | IP address this computed by the IP routing protocol and software. |
| Path Determination | Decision in which the path traffic shoul take through the network cloud. |
| Poison Reverse Update | IGRP feature intended to defeat larger routing loops. |
| Reliability | Ratio of expected to receive keepalives from a link. |
| Routed Protocol | Protocol that can be routed by a router like Appletalk, DECnet, and IP. |
| Routing Protocol | Protocol that accomplishes routing through the implementation of a specifc routing protocol like IGRP, OSPF and RIP. |
| Split horizon | IGRP feature designed to prevent routers from picking up erroneous routes. |
| Static Routing | Routing that is explicitly configured and entered into the routing table. |
| Tick | Delay on a data link using IBM PC clock tick 1/18 second equals one ? |
