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.

Actual Connection Admission Control (CAC)implementation inside the RSVP-TE protocol in MPLS-TE networks is highly limited, since the applied threshold CAC cannot provide Quality of Service (QoS) aware decision making on MPLS-TE network nodes. This prevents an effective end-to-end QoS control in a fully dynamic, application driven Label Switched Path (LSP) setup scenario. Authors of this paper have developed effective and flexible Fuzzy logic driven CAC solution (Fuzzy-CAC) which is capable of sustaining the parameters of QoS within the accepted limits and provide the dynamic setup of an application-controlled LSP. In this paper we present basic results as well as more in details discuss several adaptation approaches that help Fuzzy-CAC to operate under rapidly changing traffic characteristics.
