Selective Aggregated Session Control with QoS Provisioning for GMPLS Networks

Abstract

In this investigation the new AggSess admission control (AC) algorithm is presented for use in GMPLS networks. AggSess AC algorithm is tested on simulated network model, on which classical threshold AC algorithm is compared to the AggSess AC implementation. Main QoS characteristics are analyzed, experimental data are depicted and future research subjects are described. Ill. 6, bibl. 7, tabl. 2 (in English; abstracts in English and Lithuanian).A.

Evaluation of AggSessAC Admission Control Solution to Improve Network Revenue

“…This approach utilizes a novel admission control principle, where new flow initialization packets are collected into bundle and analysed in an intermediary manner using mutually comparisons among them, thus extending the decision-making capabilities. This paper is the continuation of previous research [12], [13], where authors focused on comprehensive explanation of conceptual idea of proposed Aggregated Session Admission Control (AggSessAC) algorithm underlining its cardinal difference from existing admission control algorithms and proposed its implementation in NGN optical networks using theoretical Matlab programming environment based model. The Matlab realization allowed to demonstrate potential of selective and mutually comparative admission strategy, but did not allow evaluating parameters such as aggregation delay (waiting time) as well as bundle size impact on the overall results, because of lack of a credible timescale.…”

“…The main feature of the AggSessAC method is based on a concept of bundle of a new flow initialization packets (demands) that are being analysed intermediary [12]. Demands handling strategy difference is depicted in Fig.…”

“…Today large flows intensity and router performance allows us to offer a new connection admission control paradigm, which was introduces by authors of the current paper in previous publications [12], [13]. This approach utilizes a novel admission control principle, where new flow initialization packets are collected into bundle and analysed in an intermediary manner using mutually comparisons among them, thus extending the decision-making capabilities.…”
