Traditionally, it is necessary to implement such proportional delay scheduling algorithms at all the routers of the network for receiving proportional delay between different classes. In this paper, we propose a new and simple model, which does not provide proportional delay but delay jitter between different classes. In addition, we point out that for receiving proportional jitter in such a DiffServ Network, it is only necessary to implement a proportional jitter scheduling algorithm at the boundary of the network. Furthermore, we propose some networks using RJPS (relative jitter packet scheduling) and WTP (waiting time priority) at different positions (core or egress) and a playout buffer delay adjustment algorithm (Concord algorithm) at the receiver. Finally we compare its performance in terms of normalized end-to-end delay with different loss probabilities at the playout buffer. Our first result showed that a proportional jitter DiffServ network achieves better performance while keeping the cost of implementation lower in some cases.","PeriodicalId":398555,"journal":{"name":"2nd European Conference on Universal Multiservice Networks.

However, the limited bandwidth of the satellite channel, the rotation of the satellite around the Earth, and the mobility of users makes QoS provisioning and mobility management a challenging task. One important mobility problem is the intra-satellite handoff management. The main contribution of this work is to propose a novel bandwidth allocation scheme along with a connection admission control strategy for LEO satellite networks. Our bandwidth allocation scheme that we call the selective look-ahead strategy (SILK), is specifically tailored to meet the QoS needs of multimedia connections. In SILK, bandwidth allocation for a connection that has stringent call dropping probability (CDP) requirements will differ significantly from that of a more tolerant application. The performance of SILK is compared to that of various bandwidth allocation schemes proposed in the recent literature. Extensive simulation results show that, compared with the other bandwidth allocation schemes, SILK offers low CDP providing for reliable handoff of on-going calls, acceptable call blocking probability (CBP) for new calls, while maintaining resource utilization high.","PeriodicalId":398555,"journal":{"name":"2nd European Conference on Universal Multiservice Networks.

A key impediment for broadband deployment is that there is no universal support for IP multicast in the Internet, because of several difficulties ranging from scalability problems to the accounting of network traffic and the enforcement of quality of service to subscribers. Also, measures that regulate the amount of traffic that can be generated from a given publisher such as committed access rate (CAR) agreements will severely limit the amount of data that can be published by a given node. In this paper, a new framework is discussed which dynamically builds an application level multicast network employing the peer nodes of a given application as network routers, thus greatly reducing the network bandwidth requirements for data broadcast. The paper discusses the current measures of network traffic accounting currently employed by Internet service providers and shows how the peer to peer model can circumvent several of the limitations of the present day Internet.","PeriodicalId":398555,"journal":{"name":"2nd European Conference on Universal Multiservice Networks.

SLA management allows a service provider to offer different levels of service guarantees and to differentiate itself from its competitors. It improves the service provider's ability to satisfy customer expectations, as the customer knows exactly what to expect in terms of quality of service. SLAs are also a key requirement for the deployment of multimedia over the Internet, i.e. for next generation networks. The Internet today is, however, a best-effort network, without the need for such strict contractual guarantees. Therefore, numerous initiatives are currently being undertaken to specify SLAs and to identify the new challenges for the provider's service and network management. The aim of this paper is to present a high-level overview of the main SLA-related issues: the actors involved in SLA negotiations, the technical specification of SLAs and the mapping of SLAs to service classes. We give an overview of ongoing SLA-related initiatives in the industrial world, standardisation bodies and the research community.","PeriodicalId":398555,"journal":{"name":"2nd European Conference on Universal Multiservice Networks.

The scheme focus on QoS considerations and a complete range of choices is presented. These choices go from a safe scheme for the network operator to a fair scheme to the customer. The in-between cases are also covered. Specific and general problems, like the incidence of users disconnecting dynamically is also discussed. The aim of this scheme is to encourage the users to disperse the resource demand instead of having a large number of direct connections to the source of the data, which would result in a higher than necessary bandwidth use from the source. This would benefit the overall performance of the network. The implementation of this task must balance between the necessity to offer a competitive service and the risk of not recovering such service cost for the network operator. Throughout this paper reference to multicast charging is made without making any reference to any specific category of service. The proposed scheme is also evaluated with the criteria set proposed in the European ATM charging project CANCAN.","PeriodicalId":398555,"journal":{"name":"2nd European Conference on Universal Multiservice Networks.
