Service Differentiation in the Internet to Support Multimedia Traffic

Abstract

Abstract. The current best-effort infrastructure in the Internet lacks key characteristics in terms of delay, jitter, and loss, which are required for multimedia applications (voice, video, and data). Recently, significant progress has been made toward specifying the service differentiation to be provided in the Internet for supporting multimedia applications. In this paper, we identify the main traffic types, discuss their characteristics and requirements, and give recommendations on the treatment of the different types in network queues. Simulation and measurement results are used to assess the benefits of service differentiation on the performance of applications.

Efficient algorithms of video replication and placement on a cluster of streaming servers

“…We are also interested in providing differentiated services from server side to requests of various clients (Tobagi et al, 2001;Zhou and Xu, 2004). The replication and placement framework in this article provides a flexible way to statically maintain multiple replicas of a video with different initial encoding bit rates.…”

Dimensioning of the IP-Based UTRAN with Multiple Node Bs for Elastic Traffic Using DiffServ QoS

“…Each DiffServ PHB has its own queue. Typically in the IP DiffServ architecture, a combination of Priority Queuing (PQ) and Weighted Fair Queuing (WFQ) is applied to support different service classes [9]. PQ is used to provide premium service (like delay-and jitter-sensitive real time services) for the highest priority; and WFQ is used in addition to serve lower priority service classes with different priorities and fairness.…”

Distributed bandwidth broker for QoS multicast traffic

“…With those traffics the dropping of the probes would occur earlier, thus making congestion more evident. Let us consider the case of VoIP traffic: according to G.711 [15], CBR traffic is generated with rate Ö of 64 Kbps, composed of frames of bits with frequency 125 sec. If 10 Mbps, then the available bandwidth in a slot is ¡ ½ ¾ ¼ bits.…”
