Give them everything they need to get their jobs done. Build networks that accommodate direct access by remote users, using leased lines for large offices and frame relay for cost-savings. Use dial-up for very small offices and individual mobile users and telecommuters. Use VPNs for smaller offices and individuals, and investigate VPNs as a strategic direction throughout the company. Solve congestion problems by segmenting the network.
Fewer users sharing the pipe gives each user more bandwidth.
Change to a switched network. Give each user a dedicated pipe, and your worries end. Use routers for multiprotocol traffic, switches to speed traffic in homogenous environments and load balancers to distribute traffic and prevent overloads. Use multilayer switches to do everything they can switch, route and balance loads. The trends toward Web-hosted managed services and applications outsourcing also require new design practices.
