SCTP and TCP Variants: Congestion Control Under Multiple Losses
White Papers Inefficiency in the current specification of SCTP's congestion control is characterized, which degrades performance when there are multiple packet losses in a single window. An SCTP variant, called New-Reno SCTP is presented, which introduces three...

Video Quality Assessment From the Perspective of a Network Service Provider
White Papers This paper considers the problem of estimating the quality of a decoded video that is transmitted over an unreliable packet-switched network. The goal is to allow the encoder to calculate the expected decoder distortion without any direct...

Charging From Sampled Network Usage
White Papers IP flows have heavy-tailed packet and byte size distributions. This make them poor candidates for uniform sampling-i.e.selecting 1 in N Flows-since omission or inclusion of a large flow can have a large effect on estimated total traffic.

TCP-Illinois: A Loss and Delay-Based Congestion Control Algorithm for High-Speed Networks
White Papers TCP-Illinois uses packet loss information to determine whether the window size should be increased or decreased, and uses queueing delay information to determine the amount of increment or decrement. This paper introduces a new congestion control...

On Scheduling and Real-Time Capacity of Hexagonal Wireless Sensor Networks
White Papers Since wireless ad-hoc networks use shared communication medium, accesses to the medium must be coordinated to avoid packet collisions. Transmission scheduling algorithms allocate time slots to the nodes of a network such that if the nodes transmit...
