Fixed Point of a TCP/RENO DiffServ Network With a Single Congested Link
White Paper The DiffServ network under consideration run TCP RENO, uses a multi-PI AQM for marking at the core and token bucket for coloring at the edges. Before proceeding with the fixed point problem, the paper describes a limitation of the current leaky... [30 Oct 2007]
Dimensioning Network Resources in DiffServ Over MPLS Based Expedited Forwarding Service Subclasses
White Paper The authors use the highest Differentiated Service Code Point (DSCP) values in DiffServ architecture, and employ the traffic engineering possibilities through MPLS techniques in order to introduce new premium services by splitting the expedited... [09 Aug 2006]
Performance Enhancements of UMTS Networks Using End-to-End QoS Provisioning
White Paper The DiffServ Code Point was utilized in the E2E UMTS QoS provisioning to differentiate different types of traffic. This paper investigates end-to-end Quality of Service (QoS) provisioning approaches for UMTS networks in a DiffServ IP network... [18 Jul 2008]
MPLS DiffServ: A Combined Approach
White Paper It talks about different approaches to map DiffServ Code Point (DSCP) to Label Switched Path (LSP) and their advantages and disadvantages. Differentiated Service (Diffserv) is the scalable Quality of Service (QoS) that is provided by many Internet... [11 Jul 2008]
An Integrated QoS Control Architecture for IEEE 802.16 Broadband Wireless Access Systems
White Paper After analyzing the current strategies to provide IntServ for the Internet connection via IEEE802.16-2004 WirelessMAN, a mapping rule and a fast signaling mechanism for providing both InterServ and DiffServ are given under Point to Multi-Point... [22 Nov 2005]
QoS Controlling for IBM Network Processor Based Gigabit Metro Switch
White Paper Contemporary many NPs have diffserv-based intrinsic QoS technologies which are multi-field classification, DiffServ attributes marking, flow metering, flow measuring, packet dropping, packet scheduling, DSCP(DiffServ Code Point) remarking, etc. [17 Jul 2008]
Providing Integrated QoS Control for IEEE 802.16 Broadband Wireless Access Systems
White Paper A mapping rule for providing DiffServ between IP layer and MAC layer is given. A fast signaling mechanism is designed to provide cross layer integrated QoS for Point to Multi- Point (PMP) mode. This paper proposes a new integrated QoS architecture... [22 Nov 2005]
Short-Term Fairness for TCP Flows in 802.11b WLANs
White Paper However, the growing need for Quality of Service (QoS) guarantees is difficult to implement in distributed systems like WLANs, where the random access protocol and the unpredictability of the wireless channel hamper their interaction with well... [20 Oct 2005]
A New Three Color Marker for TCP Flows
White Paper This paper presents an extensive performance evaluation of a new adaptive packet marking scheme, which relies on three different service classes, provided by the DiffServ network. In Differentiated Services networks, packets may receive a different... [14 Jan 2008]
Designing the Optical Internet of Greece
White Paper This paper also summarizes the expected new services and the policy based management methods, which are planed to be deployed (QoS differentiation and guarantees, MPLS, diffserv, DEN) in order to maximize the influence of this modern high-speed... [24 Feb 2004]
VoIP primer: How it works - and what the jargon means
Comment On private networks - LAN, WAN or in the carrier's core - application performance can be assured using two distinct quality of service parameters: DiffServ and MPLS. With DiffServ, information about priority is places in a packets header; with MPLS... [10 Feb 2005]
Performance Evaluation of a New Adaptive Packet Marking Scheme for TCP Over DiffServ Networks
White Paper In Differentiated Services networks, packets may receive a different treatment according to their Differentiated Services Code Point (DSCP) label. As a consequence, packet marking schemes can be devised to differentiate packets belonging to a same... [14 Jan 2008]
