Layered Bandwidth Management in ATM/SDH Networks

Abstract

ATM technology offers greater flexibility than STM technology, but in some applications this flexibility has to be compromised to realize a network that performs at least as well as the current STM implementations to achieve guaranteed Quality of Service and favorable economics. This paper presents a layered bandwidth management scheme that exploits the strengths of both STM and A TM technology to realize a more manageable and cost-effective network than is possible by applying only one of these technologies in the integrated A TM and SDH transport network.

ATM scenarios for SDH/SONET networks

“…To enhance network reconfiguration capability, selecting the right network elements to support the three different paths is one of the key concerns in the evolving network from the perspective of guaranteeing quality of service (QoS) and favorable economics. 2 It is very important to ♦ ATM Scenarios for SDH/SONET Networks…”
