Queue Dynamics Of RED Gateways Under Large Number Of TCP Flows
White Papers As the number of competing flows becomes large, the queue behavior of RED can be described by a two-dimensional recursion. This paper considers a stochastic model of a RED gateway under competing TCP-like sources sharing the capacity.

Queue Management For TCP Traffic Over 3G Links
White Papers This paper proposes 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 end-to-end connection and dedicated to one host.

Queue Management Strategies To Improve TCP Fairness In IEEE 802.11 Wireless LANs
White Papers This paper proposes two different queue management techniques to alleviate the unfairness problem, with one based on Selective Packet Marking (SPM), and the other based on Least Attained Service (LAS) scheduling.

Reducing Queue Oscillation At A Congested Link
White Papers Queue length oscillation at a congested link causes many undesirable properties such as large delay jitter, underutilization of the link and packet drops in burst. The main reason of this oscillation is that most queue management schemes determine...

Rate Stable Resource Allocation In OFDM Systems: From Water-Filling To Queue-Balancing
White Papers Water-filling is too myopic when considering longtime average performance, e.g.delay, queue lengths, and even long-run throughput. This is because such policies ignore variable state (queue length) information, while, in fact, such an information...

Aggregate Traffic Performance With Active Queue Management And Drop From Tail
White Papers Active queue management (AQM) refers to a family of packet dropping mechanisms for router queues that has been proposed to support end-to-end congestion control mechanisms in the Internet. This paper examines the performance of AQM mechanisms by...

A Variable Structure Control Approach To Active Queue Management For TCP With ECN
White Papers In this paper, a variable structure (VS) based control scheme has been designed in Active Queue Management (AQM) supporting explicit congestion notification (ECN). It has been shown that the TCP connections through the congested routers can be...

An Extensive Examination Of Data Structures Using C# 2.0 - Part 2: The Queue, Stack, And Hashtable
White Papers This paper examines three of the most commonly studied data structures: the Queue, the Stack, and the Hashtable. The Queue and Stack are specialized Lists, providing storage for a variable number of objects, but restricting the order in which the...

Efficient Queue Management For TCP Flows
White Papers Packets in the Internet can experience large queueing delays during busy periods. Backbone routers are generally engineered to have large buffers, in which packets may wait as long as half a second (assuming FIFO service, longer otherwise).
