Drop Probability Assurance for Delay-insensitive Applications
نویسندگان
چکیده
Loss differentiation is recommended as a service differentiation provided by an Assured Forwarding (AF) Per-Hop Behavior (PHB) in Differentiated Service (DiffServ) architecture. An Active Queue Management (AQM) technique is addressed as a suitable alternative to realize the service differentiation because the AF PHB should attempt to minimize longterm congestion while permitting short-term congestion in order to accommodate traffic bursts. In this paper, we introduce a desirable property of assured drop probability. We modify an existing AQM algorithm for the property so that it assures a target drop probability in a properly provisioned network. We evaluate it with other comparable schemes through simulation.

Optimization of active queue management based on proportional control system
This paper shows the design and performance of an AQM (Active Queue Management) enabled router. The design is based on a classical proportional control system. The application of such a router is to enhance streaming media over IP performance by avoiding bursty packet drop situations, control the router queue delay, and balancing packet drop, delay, and link utilization. The selected AQM equili...
متن کاملBEDS: A proposal for Best Effort Differentiated Services
We propose extending the traditional Best-Effort service with several Qualify-of-Service classes named ”Best-Effort Differentiated Services (BEDS)”. Each class has a different policy for degrading the quality of packet forwarding during congestion. For example, one class may constrain the packet queuing delay (delay-conservative), while another class may constrain the packet drop probability (d...
متن کاملTraffic Sensitive Quality of Service Controller
Internet applications have varied Quality of Service (QoS) Requirements. Traditional applications such as FTP and email are throughput sensitive since their quality is primarily affected by the throughput they receive. There are delay sensitive applications such as streaming audio/video and IP telephony, whose quality is more affected by the delay. The current Internet however does not provide ...
متن کاملNF-TCP: A Network Friendly TCP Variant for Background Delay-Insensitive Applications
Delay-insensitive applications, such as P2P file sharing, generate substantial amounts of traffic and compete with other applications on an equal footing when using TCP. Further, to optimize throughput, such applications open multiple connections. This results in an unfair and potentially poor service for other applications having stringent performance objectives. In this paper, we propose NF-T...
متن کاملApproximation Method for Performance Analysis of Queueing System with Multimedia Traffics
We consider a single server queueing system with two types of traffic where traffic of type 1 (such as data) are delay-insensitive and loss-sensitive and traffic of type 2 (such as voice) are delay-sensitive and loss-insensitive. To provide the required Quality of Service (QoS) of each type of traffic, we adopt the strict priority scheme for delay and push-out scheme with threshold for loss. Th...
