Planning Assumptions and Constraints
- technology, in-house expertise and manpower
- financial resources, aversion to risk
- research/educational needs of various departments
- scope of the project (backbone, departments)
Key Technologies
- bridges -have knowledge of Ethernet or Token Ring; have no knowledge of TCP/IP or Apple Talk; designed to improve network performance by filtering network traffic; inexpensive, fast, easy to install and manage
- routers - operate at layer 3 of OSI RM; have knowledge of higher layer protocols like TCP/IP or AppleTalk; effective in controlling the flow of traffic; enforce security polices; control the propagation of broadcasts; fairly expensive
