A Simulation Study of Using ER Feedback Control to Transport Compressed Video over ATM Networks

چکیده
Transporting video over asynchronous transfer mode (ATM) networks has been an active area of research. The Variable Bit rate (VBR) service in ATM networks is primarily designed and used for real time application like compressed voice and video. Due to compressed video is inherently bursty, the bandwidth could not be efficiently utilized. The explicit rate (ER) flow control designed for Available Bit Rate (ABR) service provides a powerful control scheme to network congestion that it may be modified to VBR service for utilise the bandwidth and control the Quality of Service (QOS) of real time video or voice. In this paper, we present a simulation study of using modified ABR flow control algorithm Enhanced Proportional Rate Control Algorithm (EPRCA) to support compressed video over the ATM network, and compare its performance with VBR transmission. .

The Feedback Based Mechanism for Video Streaming Over Multipath Ad Hoc Networks
Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...

In this paper, the operation of MPEG-2 decoder bu er is modeled and simulated when a VBR MPEG2 stream is delivered through an ATM network with jitter. End-to-end packet based analysis is performed for delivery of MPEG-2 transport streams over ATM networks. A novel approach to analyzing the decoder bu er in the presence of network jitter is given in this paper. The probability density function o...

We have developed fully functional Video Server and Client applications which can transmit, receive, decom-press and display compressed video over various networks. Our video transport allows dynamic rate control feedback, loss detection and repair request from Clients to the Server. Our experiments show how feedback-before-degradation scheme for rate adaptation maintains desired QoS for video ...
متن کاملPerformance of TCP over ABR with Long-Range Dependent VBR Background Traffic over Terrestrial and Satellite ATM networks
Compressed video is well known to be self-similar in nature. We model VBR carrying long-range dependent, multiplexed MPEG-2 video sources traffic. The actual traffic for the model is generated using fast-fourier transform of the fractional gaussian noise sequence. Our model of compressed video sources bears similarity to an MPEG-2 transport stream carrying video, i.e., it is long-range dependen...
متن کاملStatic Load Balancing of Hierarchical MPEG2 Video Streams Over VBR and ABR Services
If compressed video services such as video on-demand (VOD) and TV broadcasting will be widely provided over ATM networks, the question arises as to which class of service and which congestion control scheme are suitable for the delivery of such inherently bursty traffic. In this paper we study through intensive simulation the capabilities of VBRrt and ABR associated with rate based congestion c...
