ICESS - Traffic control scheme of VCNs' gigabit ethernet using BP
Embedded Software and Systems, 2005Co-Authors: Dae-young Lee, Sang-hyun BaeAbstract:VCNs (Virtual-Connection Networks) of gigabit-ethernet can be efficiently used to transport packet data services. The switching system will sup-port voice and packet data services simultaneously from end to end applications. To guarantee quality of service (QoS) of the offered services, source rate to send packet data is needed to control the network overload condition. Most existing control algorithms are shown to provide the threshold-based feedback control technique. However, real-time voice calls can be dynamically connected and released during data services in the network. If the feedback control information delays, quality of the serviced voice can be degraded due to a time delay between source and destination in the high speed link. An adaptive algorithm based on the optimal least mean square error technique is presented for the predictive feedback control technique. The algorithm attempts to predict a future buffer size from weight factor (slope) adaptation of unknown functions, which are used for feedback control. Simulation results are presented, which show the effectiveness of the algorithm.

Kokshenev, Roman TkachevAbstract:A model of a Virtual Connection managed by transport protocol with a mechanism of forward error correction in the selective repeat mode in the form of a Markov chain with discrete time is offered.

an architecture and methodology for mobile executed handoff in cellular atm networks
IEEE Journal on Selected Areas in Communications, 1994Co-Authors: Anthony S. Acampora, Mahmoud NaghshinehAbstract:An architecture is presented for a high-speed cellular radio access network based on ATM transport technology. Central to this approach is a new concept known as the Virtual Connection tree which avoids the need to involve the network call processor for every cell handoff attempt. Such an approach can readily support a very high rate of handoffs, thereby enabling use of physically small radio cells to provide very high system capacity, but may occasionally cause the volume of traffic to be handled by one cell site to exceed that cell site's capacity. A simple analytical methodology is developed which can be used for admission control, the purpose of which is to limit the number of in-progress calls such that two new quality of service metrics (overload probability and average time in overload) can be kept suitably low. Finally, a general framework is presented for overall system organization and signaling. >

A user tunable access lightwave network
Journal of Lightwave Technology, 1993Co-Authors: Rafael Gidron, Anthony S. AcamporaAbstract:A new approach to reconfiguration management of a wavelength-multiplexed multihop lightwave network is proposed. Unlike earlier approaches, this «User Tunable Access Lightwave Network» employs a fixed Connection diagram among the multihop access stations but allows each user to select its «home» access station by means of a wavelength agile optical transmitter, capable of retuning on a time scale comparable with the setup time of a new Virtual Connection. By so doing, it becomes possible to effect a reconfiguration with minimal impact upon existing Virtual Connections. A traffic-driven heuristic is presented which can rapidly adapt to time-varying traffic patterns and which can be implemented on a distributed basis within the multihop access stations, with each station requiring knowledge of only its own generated traffic

verizon experience with ng ethernet services evolution to a converged layer 1 2 network
IEEE Communications Magazine, 2005Co-Authors: Haida Chamas, William A Jorkma, S Liu, L Che, M A AliAbstract:This article presents Verizon's experience with deploying metro Ethernet services and some of our laboratory activities related to the convergence of layer 2/1 networks. Such convergence leverages the existing SONET and optical transport network infrastructure, and integrates layer 1 and layer 2 transport, control, and management planes within the network. Integrated service provisioning is featured, including service logic and policy that controls the admission, path selection, and transport bandwidth adjustment requirements of provisioning an Ethernet Virtual Connection within the metro Ethernet network.
