• Previous topologies– FIDDI– ATM (LANE)– SONET
Topology (cont)

• Distribution to Access layer = Gig E– SONET– ATM (ISP hand off)
• DSL Mega central
Logical Layout
Physical Layout
IP route summarization
Hardware
• FIBER– MM fiber– SM fiber (blown and conventional)
• Switches & Routers– Homogeneous core advantages
• Cisco (emphasis on open standards)
Challenges• SLA – Your everything
– Service Level Agreements should be customer based NOT tech “cool” driven.
– Money flows with service support philosophy not with trophy building.
– Service Identification • What’s on your network?• How critical is it?
– fire alarms, security, ID systems, HVAC, temperature alarms on refrigerators, Medical systems, student systems, payroll, research projects, Voice, etc..
• How to best monitor each service.• SLA with service providers
– Power• UPS, generator
