|---|
| Bandwidth | needed to relieve network congestion |
| Virtual Circuit | it exists only when needed and is established within the switch. |
| Symmetric Switch | provides switched connections between ports with the same bandwidth |
| Asymmetric Switch | provides switched connections between ports of unlike bandwidth |
| Memory Buffering | allows traffic from the 100 Mbps port to be sent to a 10 Mbps port |
| Store and Forward | the entire frame is received before any forwarding takes place. |
| Cut-Through | the switch reads the destination MAC address and begins forwarding the frame before it is completely received |
| VLANs | logically segment the physical LAN infrastructure into different subnets |
| Frame Filtering | a technique that examines particular information about each frame |
| Frame identification | uniquely assigns a user-defined ID to each frame |
| Functionality | the network must work. |
| Scalability | the network must be able to grow |
| Adaptability | the network must be designed with an eye toward future technologies |
| Manageability | The network should be designed to facilitate network monitoring and management |
| Bandwidth | Data capacity of a link |
| Delay | Length of time required to move a packet from source to destination |
| Load | Amount of activity on a network resource such as a router or link. |
| Reliability | Usually refers to the error rate of each network link |
| Hop Count | Number of routers a packet must pass through |
| Ticks | Delay on a data link using IBM PC clock ticks (approximately 55 milliseconds). |
| Cost | Arbitrary value, usually based on bandwidth, dollar expense, or other measurement, that is assigned by a network administrator |
| Convergence | when all routers in an internet are operating with the same knowledge |
| Exterior Routing Protocols | used to communicate between autonomous systems. |
| Interior Routing Protocols | used within a single autonomous system. |
| RIP | A distance vector routing protocol. |
| IGRP | Cisco's distance vector routing protocol. |
| OSPF | A link-state routing protocol |
| EIGRP | A balanced hybrid routing protocol. |
| Standard Access Lists | check the source address of packets that could be routed |
| Extended Access Lists | check for source and destination packet addresses |
| Ethernet | novell-ether |
| Token Ring | sap |
| FDDI | snap |
