“…However, most of the work so far has focused on transmission and traffic regulation over asynchronous transfer mode (ATM) networks [8], [26], of which perhaps the simplest example is the Leaky Bucket controller [24]. Video over ATM was of interest because of two reasons: 1) ATM was thought of as one of the candidate transport technologies for future broadband integrated services data networks (B-ISDN) all the way to the end user and 2) ATM networksareabletoprovideQuality-of-Service(QoS)guarantees .…”

Abstract-We consider the problem of designing systems for the transmission of video signals of the quality found in current television broadcasts, over high-speed segments of the public IP network. Our most important contribution is the definition of a network/coder interface for IP networks which gathers channel state information, and then sets parameters of the video coder to maximize the quality of the signal delivered to the receiver, while remaining fair to other data or video connections. This interface plays a role analogous to that of a Leaky Bucket controller, in that it specifies traffic shaping parameters which result in simultaneous good Quality-of-Service (QoS) for the source and good network performance. Since the network is not assumed to provide any form of QoS guarantee, fundamental to our construction is a hidden Markov model for the channel, based on which the interface solves a problem of optimal stochastic control, to decide how to configure the encoder. Other contributions are a) modifications to the standard Internet transport protocol, to make it suitable for the transport of delay-constrained traffic and to gather channel state information, and b) the design of an error-resilient video coder. Experimental studies reveal that the proposed system is able to stream video signals of the quality of current TV-broadcasts, among hosts in wide-area networks connected to the experimental vBNS backbone.

“…If the ABR connection is multiplexed with several VBR sources, B(n) is the difference between the ABR peak rate C and the aggregated rate of VBR sources. If the VBR sources are modeled as ON-OFF sources (in the literature, bursty traffic expected for ATM networks are usually modeled as ON-OFF sources [10,11]), then (see Appendix) the available bandwidth B can be modeled by the following first order stochastic difference equation…”

Available bit rate (ABR) is an emerging asynchronous transfer mode (ATM)-based telecommunication service, which dynamically allocates bandwidth to the users according to the available bandwidth in the network. However, research shows that ABR-based connections suffer from congestion at LAN-ATM gateway when ATM network abruptly reduces the bandwidth available to the gateway. Gateway congestion may result in high packet loss. This paper proposes a gateway congestion control mechanism, which controls the rate of outgoing enterprise traffic according to the available bandwidth at the gateway. Our analysis shows how to achieve a stable system and keep the packet loss below a desired threshold. Analytical results are validated by simulation. ᭧

The control of cell processes plays a central role in ATM network management and strongly influences the overall system overload behavior and the quality of service. One of the crucial control functions is the usage parameter control according to the user-network contract for a connection. Due to the slotted time of the ATM cell process discretetime models are suited for performance analysis. In this paper we first present queueing models operating in discrete-time for the cell rate monitoring, where arbitrary renewal cell input processes are taken into account. Subsequently cell processes of ON/OFF-type are considered, where the lengths of ON-and OFF-phases can be arbitrarily distributed. Numerical results are discussed aiming the proper choice of the source traffic descriptor parameter values like cell delay variation tolerance, sustainable cell rate and burst tolerance for different cell process characteristics to be enforced.
