Towards this end, we develop a hybrid error control architecture which takes into account the use of hierarchical video coding. Additionally, the architecture also includes a module which estimates the packet error rate and round trip time observed by the receiver and adjusts the level of redundancy used based on the estimate. By choosing different options in the architecture, we get different error control schemes. In this paper, we investigate the performance of five different error control schemes, namely ARQ, pure FEC, hybrid FEC/ARQ, hybrid FEC/ARQ with priority-dependent redundancy, and adaptive hybrid FEC/ARQ with priority-dependent redundancy. We evaluate the performance of these schemes using MPEG-2 video traces. The results show that pure FEC offers the worst overall performance. The ARQ scheme offers the best performance under low bit error rate and short round trip time, while the priority-aware hybrid FEC/ARQ with or without FEC adaptation offers the best performance under other conditions.","PeriodicalId":122125,"journal":{"name":"10th IEEE Workshop on Local and Metropolitan Area Networks.

H.323 is an ITU-T standard for real-time voice and video communication over packet networks. During the past two years it has become the standard on the Internet for VoIP. Another relatively recent alternative example is SIP (Session Initiation Protocol) for establishing multimedia sessions, that has been adopted as an RFC by the IETF. The cost to transmit digital information end-to-end is dropping dramatically, while there has been a tremendous increase in the available bandwidth. Not only has this been true in backbone networks, it has be-come the trend in access networks for both fixed and wireless access. The price/performance of end-user electronics is dropping while, at the same time, there has been a tremendous increase in computational power. As far as personal communication and mobility is concerned, we are in the position to create new applications and services that go far beyond what telephony systems have been concerned with and able to accomplish. One of the main contributing factors is the Internet Protocol, which allows these new applications to benefit from the fact that end-user devices are now able to use multiple services and events over a single access. The result is that we are now able to build new interactive services, which can combine both voice and data simultaneously.","PeriodicalId":122125,"journal":{"name":"10th IEEE Workshop on Local and Metropolitan Area Networks.

Its LAN-like environment enables pre-registered users to communicate with each other using a PC at any time. An STM-based system, which transfers Ethernet frames to/from users' PCs using HDLC (high-level data link control) protocol over ISDN access lines, has already been developed. Access systems that directly provide an Ethernet interface to users such as shared STM-PDS (synchronous transfer mode passive double star) and cable modem systems have recently been introduced. The communication services provided with the current access systems are basically Internet protocol (IP) services. Such access systems will be required to support protocol-free communication services as well as group communication services. We propose a new system architecture that is applicable to many kinds of access systems including shared STM-PDS and cable modem systems. It is based on MAC-over-IP where Ethernet frames from users' PC are encapsulated into IP packets in the edge device and filtered using the PC MAC (media access control) addresses in the center node. This paper describes the system architecture and its operations. The system can provide protocol-free services and guaranteed security to users. The processing load of the center node is reduced by cutting through the decapsulation of MAC-over-IP packets by controlling the ARP (address resolution protocol) packets. Performance evaluation results for a prototype system are presented.","PeriodicalId":122125,"journal":{"name":"10th IEEE Workshop on Local and Metropolitan Area Networks. Selected Papers (IEEE Cat.
