چکیده

Two time delay neural network (TDNN) based forecasting systems are proposed to perform dynamic bandwidth reservation for real-time, variable bit rate (VBR) video service in ATM networks. Both multilayered perceptron (MLP) and pi-sigma network (PSN) based systems are found to give highly reliable predictions even in a nonstationary environment. Their performance is quantiied through simulation experiments on clippings from the movie, \Star Wars". In particular, the PSN-TDNN based dynamic bandwidth reservation achieves high network utilization , loss-free transmission and reasonable delay, and its lower computational requirements make it suitable for on-line operation.

Dynamic bandwidth allocation for stored VBR video in ATM endsystems

The paper introduces a scheme for delivery of variable bit-rate (VBR) coded video from a video server over ATM networks. To solve the problem of long term variations in bandwidth requirements, a dynamic bandwidth allocation scheme is proposed. This is based on renegotiation of bandwidth during the duration of the call. An algorithm is presented, that determines optimized renegotiation points fo...

Dynamic Reservation TDMA Protocol for Wireless ATM Networks Jean-Fran

A Dynamic Reservation TDMA Multiple Access Control (DR-TDMA) protocol that extends the capabilities of Asynchronous Transfer Mode (ATM) networks over the wireless channel is proposed in this paper. DR-TDMA combines the advantages of distributed access and centralized control for transporting Constant Bit Rate (CBR), Variable Bit Rate (VBR) and Available Bit Rate (ABR) tra c e ciently over a wir...

Content-based Dynamic Resource Allocation for VBR Video in Bandwidth Limited Networks

In bandwidth limited access networks, dynamic resource allocation can increase the link utilization and decrease the required network bu ering. In this paper, we propose a new policy in which the visual content of video is used to determine the bandwidth needed for its transmission. The policy is based on a novel framework of content-based video tra c modeling, introduced in [5]. Based on simul...

Source Modeling, Queueing Analysis, and Bandwidth Allocation for VBR MPEG-2 Video Traffic in ATM Networks

In this paper we study source modeling, queueing analysis and bandwidth allocation issues of VBR MPEG-2 video traffic in ATM networks. We propose a mini-source based discrete-time Markov modulated deterministic process (D-MMDP) to model the macro-frame smoothed VBR MPEG-2 traffic. It is shown that such a modeling technique is sufficiently accurate and simplies the involved queueing analysis for...

Content-based VBR Video Tra c Modeling and its Application to Dynamic Network Resource Allocation

In bandwidth limited networks and network interfaces, dynamic resource allocation can substantially increase the link utilization and also decrease the required network bu ering. In general, there are two important tradeo s e ecting the network utilization. First, tradeo between e ciency of the real-time dynamic resource allocation and the policy controlling the renegotiation frequency. Second,...
