QoS-Aware Multicasting in DiffServ Domains

by Zhi Li, Prasant Mohapatra , 2002
"... Although many QoS-based multicast routing protocols have been proposed in recent years, most of them are based on per-flow resource reservation, which cannot be deployed within differentiated services(DiffServ) domains. In this paper, we propose a new QoS-aware multicast routing protocol called QMD, ..."

A New Routing Architecture for DiffServ Domains

by Shiping Chen, Yibei Ling, Key Words - SIAM Journal , 2003
"... This paper proposes a new DiffServ routing architecture (PAP) that integrates the admission control signaling and the QoS routing. It differs from traditional routing in its ability to route most Expedite Forwarding (EF) traffic along the shortest paths while making use of alternative paths to absor ..."

Price-Based Call Admission Control in a Single DiffServ Domain

"... We consider the problem of scalable call admission control (CAC) in a DiffServ network and propose a new CAC scheme. Initially, a certain fraction of the bandwidth of the network is reserved for admission-controlled traffic, and this reservation is carried out according to the hose model, a model th ..."

Quality of Service in a DiffServ Domain using Policy-Based Management

by Marcial P. Fernandez, Aloysio de C.P. Pedroza, José F. Rezende , 2001
"... This paper proposes a framework that offers QoS in a DS domain using Policy-based Management and fuzzy logic techniques. The QoS controller recon gures all DS nodes according to ingress traffic and domain policies. Policy Based Management is used in this framework to provide QoS in DS domain, contro ..."

A Tree Building Technique for Overlay Multicasting in DiffServ Domains

by Baijian Yang, Abdol H. Esfahanian, Lionel Ni - in diffserve domain,” International Conference on Internet Computing , 2003
"... Overlay multicasting technology is now considered as a promising alternative to the native IP multicasting. While many studies are currently focused on how to build an overlay tree/mesh on top of conventional networks in a self-organized fashion, only limited attention has been directed toward QoS p ..."

S provisioning. QoS can be provisioned by leveraging the implementation of differentiated services in the Internet. In this paper, we have proposed an incremental insertion tree-building algorithm to avoid extensive signaling overhead in differentiated service domains. The simulation results depict

Policy-Based Management providing QoS in a DiffServ Domain

by Marcial Porto Fernandez, Aloysio Castro, P. Pedroza, Jos Ferreira De Rezende
"... The Differentiated Services architecture has been proposed to offer quality of service in the Internet. Most works on Diffserv (DS) handles QoS guarantees in a per node basis, which assumes that assuring QoS in a single node also leads to the desired QoS in the entire DS domain. Nevertheless, this i ..."

Performance Analysis of DiffServ Domain with Heterogeneous Queuing and Scheduling Schemes

by Mohsin Iftikhar
"... The Internet is consisting of many different interconnected network domains. Each network domain is having its own policies and procedures to provide Quality of Service (QoS) to the end-user. The target of provisioning and managing end to end QoS solution in the internet is one of the main challenge ..."

Analytical Model of Pre-Congestion Notification (PCN) for Multimedia Traffic over DiffServ Domains

by Jinjing Jiang, Raj Jain
"... Abstract—IETF Pre-Congestion Notification (PCN) working group is working on mechanisms to ensure quality of service of voice and video traffic within a DiffServ domain in the Internet. These mechanisms operate at the domain boundary based on congestion information from within the domain. The reactio ..."
