Connection Admission Management in ATM Networks Supporting Dynamic Multi-Point Session Constructs
Pratyush Moghé, Izhak Rubin · 1995
A framework for admission management of session-level requests exhibiting space/time heterogeneity is developed. A single sub-threshold based link-level connection admission scheme for a mix of uni-point/static session and multi-point/dynamic session Virtual Channel Link requests (VCLRs) is designed and evaluated under different scenarios. Aside from external blocking, internal loss is introduced as an important QOS parameter for multipoint/dynamic session services. Concepts of service-optimal and throughput-optimal sub-thresholds are formulated. Finally, we outline a network algorithm that designs link-level sub-thresholds in accordance with end-to-end session-level QOS parameters.
