4 Long Term Planning 3-5 years typically • How many $ are needed to get a usable network? • What sort of network performance can we get with Y Network Design Issues additional $? • What should our network look like? • What Technology should be used? • What layer should provide protection? Telcom 2110 7 Can classify network design problems in several ways one method is based on geographical size 1. Access Networks Types of Network Design LANs, Campus, Residential networks, Cellular networks, etc 2. Metropolitan Networks (Metro Nets) Interconnection of central offices, POPs, corporate locations in a city, campus backbone network Higher bandwidth, may include leased lines 3. Wide Area Networks (WANs) or Long Haul Networks Telcom 2110 8 Private and Public Backbone networks (UUNET, AT&T) Interexchange Carriers
