Abstract:
1. A method of admission control for inelastic applications traffic (IAT) in a communication network, comprising: (a) configuring a passive control state (PCS), an active on-demand control state (AoDCS), and an active continual control state (ACCS) for performance measurements in the network; (b) executing the PCS when there is an active session between IAT-based devices on monitored interconnect segments of the network; (c) executing the AoDCS when there is low probability of a new session between the IAT-based devices; (d) executing the ACCS when there is high probability of a new session between the IAT-based devices; (e) switching from the PCS to ACCS when there is no active session during a first pre-determined time interval T (f) switching from the ACCS to AoDCS when there no active session during a second pre-determined time interval T (g) switching from the ACCS to PCS when an IAT call is placed; and (h) switching from the AoDCS to PCS when an IAT call is placed; wherein admit and reject decisions for placed IAT calls are made based on the results of the performance measurements performed during the respective control state.
