Protocols for existing and planned applications
- Technologies: Ethernet, Token Ring, FDDI, ATM, ISDN...
- Routing: static, dynamic; fixed (PVCs)
- Network: TCP/IP, AppleTalk, NetBEUI, IPX/SPX….
- Services: NIS, DNS, print,mail,ftp, telnet…..
- Addressing: flat or hierarchical; fixed or dynamic
Timing and delay considerations
- access time and response time (function of amount of traffic generated by users, available bandwidth, networking devices)
- what is the element of delay that most impacts response time ?
- Users want minimum delay and maximum throughput
- Switch performance: 500,000 pps
