An analytical framework for modeling a network of Random Early Detection (RED) queues with mixed traffic types (e.g. TCP and UDP) is developed. Expressions for the steady state goodput for each flow and the average queuing delay at each queue are derived. The framework is extended to include a class of RED queues that provides differentiated services for flows with multiple classes. Finally, th...

In this paper, we propose a first-order discrete model for random early detection (RED) with nonlinearity, focusing on the average queue size in router. The RED is representative router-based algorithm congestion control. Congestion avoided by discarding packets at using packet drop probability function and RED. Our proposed replaces linear of original nonlinear can continuously change nonlinea...

cell free dna (cfdna) is a genetic biomarker that is present in serum or plasma in high concentration in many types of cancer. identification of circu-lating cancer related dna molecules in serum or plasma is a non-invasive tool for early diagnosis and prognosis in many cancer patients. for this review, study selection and data extraction were performed by the authors. detection of point mutati...

Active buffer management can improve the performance of Transmission Control Protocol/Internet Protocol-based networks. Random early detection (RED), an active queue management scheme, has been proposed by the Internet Engineering Task Force for next-generation Internet routers. RED uses a number of parameters, such as buffer thresholds, a packet drop probability and a weight parameter. RED suf...

We propose a novel active queue management scheme tailored to the specific characteristics of third generation (3G) cellular networks. Such links are often the bottleneck for an endto-end connection and dedicated to one host. Taking advantage of these specific characteristics, we developed a queuing scheme that is simpler than popular Random Early Detection (RED) schemes. Despite its simplicity...

Many applications require fast data transfer over high speed and long distance networks. Compound TCP(CTCP) is a novel congestion control algorithm for high-speed and long delay networks. This paper develops a discrete time dynamic feedback model of a congestion control system with CTCP under random early detection (RED). We find that periodic doubling bifurcation occurs when varying the RED co...

The Internet is established on the best-effort service model. The Transmission Control Protocol employed in the current Internet has both fairness and efficiency issues. Pricing scheme has been proposed to address the fairness issue and prevent aggressive users occupying excessive network resource. Random early detection (RED) for the incipient congestion in routers, together with explicit cong...

This paper studies congestion control in local wireless networks supporting transmission control protocol (TCP) under random early detection (RED). In general, congestion delays may cause instability of the routers running active queue management (AQM) protocols such as RED. Moreover, its management efficiency could be reduced by serious queue oscillation. To improve these two drawbacks, we pro...

Abstract—Today’s computer networks support only best-effort service, yet future packet networks will have to support realtime communication services that allow clients to transport information with performance guarantees expressed in terms of delay, delay jitter throughput, and loss rate. Random Early Detection (RED) algorithm is one of the scheduling mechanisms used in IP network. RED is an a...

AQM (Active Queue Management) mechanism, which performs congestion control at a router for assisting the end-to-end congestion control mechanism of TCP, has been actively studied by many researchers. For instance, RED (Random Early Detection) is a representative AQM mechanism, which drops arriving packets with a probability being proportional to its average queue length. The RED router has four...
