Resource and Connection admission control in real-time Transport protocols with deterministic QoS guarantees
Proceedings of INFOCOM'95, 1995Co-Authors: N.d. GeorganasAbstract:Real-time multimedia applications will require guaranteed quality of service (QoS) such as a bound on the maximum message delay and/or on the maximum message loss rate. This poses an exciting challenge to the highspeed Transport protocol design and implementations. In this paper, we study the resource and Connection admission control algorithms, and give the necessary and sufficient conditions for the schedulability, of n real-time Transport Connections at a destination host under preemptive and non-preemptive deadline scheduling policy for deterministic QoS guarantees. These necessary and sufficient conditions form the mathematical basis for the deterministic QoS guarantees in real-time Transport communication services. On the basis of these necessary and sufficient conditions, we give the Connection admission control algorithms for deterministic QoS guarantees. We also calculate the buffer space needed for each real-time Transport Connection. The results show that real-time Transport Connections with deterministic QoS guarantees can reserve the buffer space at the establishment phase, and no flow control mechanism is required during the data Transport phase. Our results could be applied to other fields as well, such as real-time operating systems.

Resource and Connection admission control in real-time Transport protocols
Multimedia Computing and Networking 1995, 1995Co-Authors: N.d. GeorganasAbstract:Support for real-time multimedia applications is becoming an essential requirement for future high-speed networks. Many of these real-time applications will require guaranteed quality of service (QoS) such as a bound on the maximum message delay and/or on the maximum message loss rate. This poses an exciting challenge to the high speed Transport protocol design and implementations. In this paper, we study the resource and admission control algorithms for real-time Transport Connections, and give a necessary and sufficient condition for the schedulabiltiy of n real-time Transport Connections at a destination host under deadline scheduling policy for deterministic guarantees of QoS. We propose the deadline scheduling with interrupt points policy, under which we give a necessary and sufficient condition of the schedulability of n real-time Transport Connections for statistical guarantees of QoS. These necessary and sufficient conditions form the mathematical basis for the QoS guarantees in Transport communication services. Based on the necessary and sufficient conditions, we give the Connection admission control algorithms for deterministic guarantees and statistical guarantees of QoS respectively. We also calculate the buffer space needed for each real-time Transport Connection. Our results could be applied to other fields as well, such as real-time operating systems.

The land use—Transport Connection: An overview
Land Use Policy, 1996Co-Authors: Peter Newman, Jeffrey KenworthyAbstract:There is a growing international movement, ‘The New Urbanism’, which seeks to reconnect Transport with land use and in particular to establish transit-oriented development where higher-density, mixed-use areas built around high-quality transit systems provide a focused urban structure that can help to loosen the grasp of automobile dependence. There are many case studies around the world of cities which demonstrate this process of reconnecting land use and Transport. The cases of Singapore, Hong Kong, Zurich (Switzerland), Copenhagen (Denmark), Freiburg (Germany), Toronto and Vancouver (Canada), Portland, Oregon (USA) and Perth (Australia) are briefly described here to show the various levels of achievement in very different environments around the world.

Influence of the Pipeline Effect on the Delay of the Multipacket Message in Multilink Transport Connection
Communications in Computer and Information Science, 2016Co-Authors: Vladimir Kokshenev, Pavel Mikheev, Sergey Suschenko, Roman TkachyovAbstract:A stochastic model is proposed of the process of information transfer of multipacket messages in a multilink Transport Connection with distortion of the packets on separate areas of hops, differentiated by accounts of the pipeline effect. We investigate the influence of the level of distortions of protocol data units in a separate part of Transport Connections and the duration of the timeout of non-use of an end-to-end acknowledgment in probability-time characteristics of the Transport protocol.
