in average queue length for a RED controlled queue. 1 1 The RED Algorithm In computer network traffic modeling the Random Early Detection (RED) algorithm is a congestion control mechanism which involves the dropping of packet arrivals at

The RED algorithm is one of the active queue management methods promoted by the IETF for congestion control in backbone routers. We analyze the dynamic behavior of a single RED controlled queue receiving a Poisson stream with time varying arrival rate, describing the aggregate tra#c from a

Assume that each object in a database has m grades, or scores, one for each of m attributes. For example, an object can have a color grade, that tells how red it is, and a shape grade, that tells how round it is. For each attribute, there is a sorted list, which lists each object and its grade

-depth understanding of the RED algorithm. Using the tools developed in this paper, we present a critical analysis of the RED algorithm. We explain the role played by the RED configuration parameters on the behavior of the algorithm in a network. We point out a flaw in the RED averaging mechanism which we believe is a

Abstract-This paper presents Random Early Detection (RED) gateways for congestion avoidance in packet-switched networks. The gateway detects incipient congestion by computing the average queue size. The gateway could notify connections of congestion either by dropping packets arriving

are extracted using ridge energy direction algorithm. It uses two directional filters i.e. horizontal and vertical oriented. The final template is generated by comparing the two templates and considering the predominant edge. This final template is match with the stored one using hamming distance and the match

-congestion-controlled realtime applications threatens unfairness to competing TCP traffic and possible congestion collapse. We present an end-to-end TCP-friendly Rate Adaptation Protocol (RAP), which employs an additive-increase, multiplicative decrease (AIMD) algorithm. It is well suited for unicast playback of realtime

It has been observed that Internet gateways employing Transport Control Protocol (TCP) and the Random Early Detection (RED) control algorithm may exhibit instability and oscillatory behavior. Most control methods proposed in the past have been based on analytical models that rely on statistical
