"A proposed framework of QoS management over multicast transport"
نویسندگان
چکیده
This paper describes a framework of QoS management for one-to-many multicast communications in the context of a new multicast transport protocol called the Enhanced Communication Transport Protocol (ECTP). ECTP is a transport protocol designed to support Internet multicast applications, such as audio and video, which is currently being standardised in ITU.T SG7. ECTP operates over IP networks that have IP multicast forwarding capability. This framework consists of QoS management operations: “Negotiation, Monitoring and Maintenance” and ECTP connection management functions: “Connection creation, Data Transfer and Termination”. We propose a mapping architecture for QoS management operations over ECTP connection management functions to address the QoS needs of multicast applications. KeywordsQuality of Service (QoS) management, Enhanced Communication Transport Protocol (ECTP), Resource ReSerVation Protocol (RSVP).

Meeting QoS Guarantees by End-to-End QoS Monitoring and Adaptation
The design and implementation of the transport layer of a native ATM protocol stack and its embedding into an overall architecture that provides end-to-end quality of service (QOS) is presented. Within this architecture, the typical transport functionalities are enlarged with QOS monitoring and adaptation mechanisms. A QOS-based application programming interface is proposed that shields applica...
متن کاملCall Admission and Resource Reservation for Multicast Sessions
Many multicast applications, including audio and video, require quality of service (QoS) guarantees from the network. Hence, multicast admission control and resource reservation procedures will be needed. In this paper we present a general framework for admission control and resource reservation for multicast sessions. Within this framework, efficient and practical algorithms that aim to effici...

In this paper, we present MRMA, a multicast resource management architecture des...
متن کاملQoS for multimedia on the Internet
The growth of multimedia on the Internet is evidently increasing. The advances in the video compression (e.g., H.263) and audio compression (e.g., G.729) that enables transmitting video and audio streams over low speed links, and the vast growth of palm and ubiquitous computing create a strong motivation and new challenges for wireless multimedia. On the other hand, providing high bandwidth hig...
