Differentiated Services Ensuring Qos on Internet
نویسندگان
چکیده
Differentiated Services is the most advanced method for traffic management which provides QoS. QoS is essential for today’s internet. QoS represents set of techniques necessary to manage throughput, packet loss and delay. Traffic Conditioners or Policers are the most important components of differentiated services. In this research, different Traffic Conditioners or Policers are compared on the basis of QoS parameters (Performance metrics) which are throughput, packet loss and delay to provide QoS on internet. Traffic classification and traffic conditioning are important functions of differentiated services also known as admission control which are governed by service level agreement (SLA). Traffic classification and traffic conditioning is done by traffic conditioners at edge routers. Goal of this research is to choose the best Traffic Conditioner to apply from source to destination pair because only one traffic conditioner can be applied from source to destination so that QoS can be guaranteed.

A Fuzzy Based Three Color Meter/Marker for Diffserv Networks (RESEARCH NOTE)
Differentiated Services (Diffserv) which was proposed by Internet Engineering Task Force (IETF), is a scalable and robust model for providing the end-to-end QoS. In the Diffserv networks, metering mechanisms are used to measure traffic stream. The single rate Three Color Meter (srTCM) [1],which was proposed by IETF, meters an IP packet stream and marks its packets either green, yellow, or red....
متن کاملAdvanced operations research techniques for multi-constraint QoS routing in internet
Internet Traffic has grown exponentially over last few years due to provision of multiple class services through Internet backbone. With the explosive use of Internet, contemporary Internet routers are susceptible to overloads and their services deteriorate drastically and often cause denial of services. In this paper, an analysis is made how forecasting technique, routing algorithm and Genetic...

The need for Quality of Service (QoS) on the Internet is increasing everyday due to the wide dissemination of new communication services with more stringent demands from the network. There have been several proposals for QoS provisioning, particularly, the Integrated Services and Differentiated Services frameworks developed on the Internet Engineering Task Force (IETF). As the deployment of Dif...
متن کاملAchieving End-to-End QoS in the Next Generation Internet: Integrated Services Over Differentiated Service Networks
Currently there are two approaches to provide Quality of Service (QoS) in the next generation Internet: An early one is the Integrated Services (IntServ) with the goal of allowing end-to-end QoS to be provided to applications; the other one is the Differentiated Services (DiffServ) architecture providing QoS in the backbone. In this context, a DiffServ network may be viewed as a network element...
