چکیده
In t.his paper we study the problem of optimal Ijuffer space priority control in an ATM network node. 'l'lie bulfer of a transmission link is shared among the cclls of several traffic classes waiting for transmission t.lirough t,he link. When the number of cells to be st,ored in the buffer exceeds the available buffer space, ccr ia i i i cells have to be dropped. Different traffic classes have different sensitivities to cell losses. By a.ppropriately selecting the classes of cells which are dropped in case of overflow, we can have the more sensit.ive classes suffer smaller cell losses. Arriving cells rnight. be blocked from entering the system or they rr1a.y be dropped after they are already in the buffer. Ilel~ending on the control that we have on the system, t.tiree classes of policies are distinguished. In each one, policies that schedule the buffer allocation in some opt irnal manner are identified.

Mobile ad hoc network congestion control is a significant problem. Standard mechanism for congestion control (TCP), the ability to run certain features of a wireless network, several mutations are not common. In particular, the enormous changes in the network topology and the joint nature of the wireless network. It also creates significant challenges in mobile ad hoc networks (MANET), density ...
متن کاملGeneralised Minimum Queuing Delay: An Adaptive Multi-rate Service Discipline for ATM Networks - INFOCOM '99. Eighteenth Annual Joint Conference of the IEEE Computer and Communications Societies
In this paper, we propose a generalised minimum queuing delay (GMQD) service discipline for high speed networks, mainly asynchronous transfer mode (ATM) networks. This proposed scheme is similar to service disciplines based on fair queuing, but instead of using only a single service rate for each session for its entire connection lifetime, multiple service rates are used. The service rate of an...
متن کاملMeasurement Based Optimal Source Shaping with a Shaping+Multiplexing Delay Constraint - INFOCOM 2000. Nineteenth Annual Joint Conference of the IEEE Computer and Communications Societies
Most on-line (i.e., not stored) Variable Bit Rate sources would find it difficult to a priori declare the traffic parameters required by a connection admission control strategy. There is thus the problem of measurement based on-line estimation of source parameters. In this paper we address the problem of selection of source parameters based on minimising a bufferbandwidth cost function in the n...

A n ATX system needs a sophisticated and real-time connection admisszon controller not only to guarantee the required quality-of-service (QoS) for existing calls but also to raise the system efficiency. Input process has a powerspeciral-density (PSD) which explicitly contains the correlation behavior of input t...
