The simulation results show that coordination at the edge of the network makes better use of the available bandwidth and improves the TCP's performance over ATM ABR for a range of performance metrics such as the cell loss ratio, the packet retransmission ratio and the throughput.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).

In a dynamic, synergistic, and geographically broad environment, cross-domain resource management is becoming an important factor for application quality of service. We present a middleware architecture and initial implementation of that middleware that satisfies applications according to expected requirements, application service level agreement and distributed networked resources in and beyond the local environment. The networked resources are grouped in a hierarchical manner and their usage is optimized through the resource management system. This framework presents the same interface for any given resource type, with only the parameters changing to reflect that resources' specific requirements. This system enables interoperability, dynamic service discovery, and management functions such as monitoring, controlling and reporting, and dynamic reconfiguration and management.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).

This paper considers the combination of the pricing scheme and the whole QoS control framework. Firstly, a multi-level market model for the Internet differentiated services is presented. Based on it, a flexible QoS control framework is proposed. It consists of three major blocks: intelligent agent (IA), pricing broker (PB) and local pricing agent (LPA). Among them, a hybrid-pricing scheme is used as a tool for traffic control. The proposed framework provides a simple and flexible way to improve QoS over the networks via pricing technology.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).

It proposes a set of two protocols, the subnet protocol with efficient broadcast (SP-EB) and the pro-active link-state routing protocol (PALSR). PALSR is a pro-active link-state routing protocol while SP-EB is a datagram protocol that uses the topology information from PALSR to reduce redundancy in the flooding of broadcast traffic. In addition to providing an efficient broadcast mechanism, the solution also provides for unicast datagram delivery, although this is not discussed in this study. OPNET simulations were carried out to evaluate the relative performance, in terms of throughput, message drop rate and delay, of this solution versus the ideal flooding mechanism in performing network broadcast. Simulations showed that the proposed solution should be supported by a fair channel access mechanism. The simulation results also demonstrated that performance improvement is evident in a typical multi-hop PRNET and most significant when the network is near fully connected.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).

The Receiver-driven Layered Multicast (RLM) is one of the most popular receiver-based rate adaptation algorithms. However, RLM is relatively slow in adapting changes in the bandwidth of the network. Its adaptive control is based on packet loss rate. A number of extensions and variants of RLM have been proposed in the literature to improve some of these weaknesses. However, the responses of the receivers are improved at the expense of protocol complexity. In this paper, a receiver-based adaptive multimedia system using the RLM protocol for rate control is implemented. The RLM algorithm is modified to minimise congestion in the network and to reduce the processing overhead. We have also investigated whether the interframe jitter is an appropriate measure of the network congestion, and how it can be used to decide whether a receiver can subscribe to a higher layer at a given point of time. A heuristic method is used to determine the interframe jitter values that the system can tolerate. The modified RLM algorithm is also integrated with the encoding and decoding of the MPEG video to evaluate the overall performance. The preliminary results demonstrate that rate control using the inter-frame jitter has better video quality than that using packet loss rate.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).

We design and evaluate two different aggregation schemes (asymmetric simple and full-mesh). Information aggregated includes available bandwidth, delay and cost. In the past, the definition of the cost function has received much less attention. We study two approaches: the Markov decision process (MDP) approach and the competitive on-line (COL) routing approach. Our simulation results show that the proposed asymmetric simple aggregation scheme yields a very good performance while it significantly reduces the amount of advertised information. Among these two link cost functions, the MDP-based approach provides a systematic way of defining the call admission function and yields a better network utilization than the COL-based approach.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).

Nowadays the Internet is no longer a communication tool dedicated to universities and governments for research purposes and low cost communication. In a period of more or less 5 years, the Internet has become a very familiar and popular tool. However, the growth in the number of Internet users, the number of hosts connected to the World Wide Web, and the number of companies establishing a Web presence has brought to light a weakness in the Internet protocol (IPv4): the network address space is not adequate to sustain its continued growth into the next millennium. This paper explores an emerging architecture of the Internet based on network address translation (NAT) and the alternatives thereof. To this end, it presents and compares various mechanisms for alleviating the network address shortage by separating public and private address spaces. The benefits and shortcomings of NAT are described, as well as a new network address reuse mechanism known as Realm specific IP (RSIP). Furthermore, this paper extensively describes improvements to the latter mechanism which is becoming very popular. Finally, the paper explains how network address reuse technologies are about to break into the adoption of the newly designed Internet protocol, IP version 6.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).

These are mainly found on circuit-switched networks where there is dedicated bandwidth allocation, ensuring a good transmission link. However as packet switched networks become more evolved due to their interesting properties of being able to share the available bandwidth, multicast communication is increasingly employed on these networks. To provide reliability in point-to-multipoint communications system across a satellite link, especially for real-time applications, a scheme employing a novel forward error correction (FEC) is presented. The scheme uses an XOR (exclusive-OR) coding technique to generate the redundancy. Its attraction is the ability to adjust the rate of coding according to the varying condition of the link. By using this transmission strategy, the proposed scheme is implemented at the transport and the data link layer to enhance multicast communication services.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).
