In this paper we propose a scalable framework for providing differentiated QoS multicast channels for end users with heterogeneous requirements based on the Source Specific Multicast (SSM) model, which we name QoS Source Specific Multicast (QSSM). By encoding each QoS service class into a multicast group address and by maintaining the corresponding mapping table at the edge of each DiffServ dom...

Conventional Quality of Service (QoS) control techniques are designed for achieving network-level QoS objectives. Due to the large differences between network-level and application-level QoS properties, these techniques cannot provide desirable QoS for video users. Previous work has been conducted to design a packet scheduling approach where application requirements and network-level QoS object...

This memo analyzes provider-to-provider Quality of Service (QoS) agreements suitable for a global QoS-enabled Internet. It defines terminology relevant to inter-domain QoS models. It proposes a new concept denoted by Meta-QoS-Class (MQC). This concept could potentially drive and federate the way QoS inter-domain relationships are built between providers. It opens up new perspectives for a QoSen...

Existing routing algorithms treat Quality of Service (QoS) parameters and secure routing as completely separate entities requiring separate algorithms. In this paper we propose secure QoS Distance Vector and secure Bellman-Ford-Moore routing algorithms that meet QoS requirements and satisfy security concerns. Security is achieved by placing filters in the network. The routing algorithms generat...

This paper outlines an architecture that intends to ensure Quality of Service (QoS) to applications using the publisher-subscriber paradigm. The key idea is to subscribe information not only by subject and content but also according to QoS parameters. This must be done with cooperation of all intervenients: publishers, which should tag information they are producing with application-level QoS p...

QoS is essential, but for mobile environment, it is difficult to achieve QOS when compared to wired network due to poor communication environment and mobility problems. In this document we explore the prominent efforts done in literature to provide schemes to do QoS in Wireless. We especially concentrate on resource reservation schemes. This document addresses cellular network QoS (mobile user ...

In this paper, the authors develop a comprehensive framework for QoS management based on soft probabilistic contracts. The authors approach also encompasses general QoS parameters, with “response time” as a particular case. In addition, the authors support composite QoS parameters, for example, combining timing aspects with “quality of data” or security level. They also study contract compositi...

Quality of service (QoS) is an important consideration in networking, but it is also a significant challenge. Providing QoS guarantees becomes even more challenging when you add the complexities of wireless and mobile networks. This paper discusses the challenges and solutions involved in providing QoS in wireless data networks. Multiple techniques for providing service guarantees are presented...

The evolution of the Internet as an important communications infrastructure for the public and the convergence of various network services and applications over the Internet have been intensifying the demand for QoS-support in the Internet. The main goal of QoS-support in the Internet is to provide assured network performance relative to the various applications’ needs at reasonable incremental...

Quality of service (QoS) has been always controversial in resource shared networks. Scheduling as a packet prioritizing mechanism at Data Link Layer (DLL) contributes to QoS guarantee provisioning significantly. In this paper, a novel packet scheduler is developed in wireless cellular networks. The proposed scheme provides QoS-guaranteed service for the applications running on the sensor nodes ...
