Limitations on using IP Routers forNetwork Expansion

> All Services to IP IP Router

Everywhere

> Network Traffic Characteristics

> Majority of the network traffic are pass-through traffic

> Economical Viability

> Switching equipment at L2 layer and beloware always more cost effective than L3

Routers

> The longer the network traffic is kept at L2before handing off to a L3 Router, the

better the savings would be

> Implementation and MaintenanceComplexity Considerations

> Performance Reliability Considerations

> IP is still less reliable than L1/L2 transportmechanism

Routers-Only Scenario

Router + L2 Switching Combo(note: 80% traffic are pass-through traffic)

PTN implementation model at Hubsites

Implementing PTN solution at Hub site enables:

Multi-service grooming of traffic from cell sites ATM IMA, E1/T1 TDM, Ethernet etc.

Using statistical multiplexing to reduce leased line transport cost

Multiple QoS service classes to ensure SLA

PTN implementation model at RNCsites

Implementing ATM switching at 8660/8860 to replace ATM switching done at RNC

Example: UBR+ bandwidth compression ratio 1:8

PTN solution at RNC sites can interwork with MPLS core networks without needing additional L3routers at RNC sites

Compatible with legacy transport system and yet future proofing investment with PTN solution:

Enables seamless migration of TDM/ATM traffic to All-IP networks

Enables Layer 2 to Layer 3 interworking
