An Overlay-based Congestion Management for Differentiated Services Network
نویسندگان
چکیده
This paper presents a new overlay-based congestion management mechanism that provides the proportional fairness among competing aggregates and the improvement in packet loss ratio for Differentiated Services (DiffServ) network. In the proposed scheme, a QoS control packet is sent from the ingress to the egress router every fixed time interval. The ingress router employs a simple additive increase and explicitly decreases algorithm to adjust the aggregate’s sending rate according to the QoS information reflected back from the egress routers. For the performance evaluation of the proposed scheme, we present the simulation of the proportional fairness of aggregates traffic and packet loss ratio.

Distributed Dynamic Capacity Contracting: An overlay congestion pricing framework for differentiated-services architecture
Several congestion pricing proposals have been made in the last decade. Usually, however, those proposals studied optimal strategies and did not focus on implementation issues. Our main contribution in this paper is to address implementation issues for congestion-sensitive pricing over a single domain of the differentiated-services (diff-serv) architecture of the Internet. We propose a new cong...
متن کاملCongestion and Error Control in Overlay Networks
In recent years, Internet has known an unprecedented growth, which, in turn, has lead to an increased demand for real-time and multimedia applications that have high Quality-of-Service (QoS) demands. This evolution lead to difficult challenges for the Internet Service Providers (ISPs) to provide good QoS for their clients as well as for the ability to provide differentiated service subscription...
متن کاملAn Edge-to-Edge Overlay Congestion Control Architecture for the Internet
This paper proposes an edge-to-edge overlay congestion control architecture for managing traffic aggregates. Motivated by scalability issues, the core rate-based scheme breaks up congestion in the intermediate network(s) and distributes it across overlay edges leading to superior besteffort performance. Consolidation of bottlenecks at overlay edges also enables the creation of purely edge-based...
متن کاملApplication of Robust Control Issues in Differentiated Services Networks
The rapid growth of the Internet, the massive amount of data traffic it carries and increased demand to use the Internet for time-sensitive voice and video applications necessitates the design and utilization of effective congestion control algorithms. Existing TCP/IP protocol suite has been designed for best effort (delay tolerant) services and cannot effectively support time sensitive applica...
