This document describes how the currently specified IPv6 flow label can be used to enhance layer 3/4 (L3/4) load distribution and balancing for large server farms.

Hash-based load-balancing techniques are widely used to distribute the load over multiple forwarding paths and preserve the packet sequence of transport-level flows. Forcing a long-lived, i.e., elephant, flow to follow a specific path in the network is a desired mechanism in data center networks to avoid crossing hot spots. This limits the formation of bottlenecks and so improves the network us...

By investigating flow level characteristics of Internet traffic, we are able to trace the root of load imbalance in hash-based load-splitting schemes. We model flow popularity distributions as Zipf-like and prove that under typical Internet traffic mix, a hash scheme cannot balance workload statistically, not even in the long run. We then develop a novel load-balancing packet scheduler for para...

Load flow (LF) study, which is performed to determine the power system static states (voltage magnitudes and voltage angles) at each bus to find the steady state operating condition of a system, is very important and is the most frequently carried out study by power utilities for power system planning, operation and control. In this paper, a radial basis function neural network (RBFN) is propos...

A novel bulk flow TCP and its routing performance of the optical IP networks is analyzed numerically. Four types of data transmission viz. fixed size flow discard, fixed size early flow discard, variable size flow discard and variable size early flow discard for the optical domain are investigated. Various probability density functions for the data transmissions are derived for the computation....

Opportunistic routing (OR) has been proposed to improve the performance of wireless networks by exploiting the multi-user diversity and broadcast nature of the wireless medium. It involves multiple candidate forwarders to relay packets every hop. The existing OR doesn’t take account of the traffic load and load balance, therefore some nodes may be overloaded while the others may not, leading to...

This paper presents distributed algorithms for both radial and looped load flows for unbalanced, multi-phase power distribution systems. The distributed algorithms are developed from tree-based sequential algorithms. Formulas of scalability for the distributed algorithms are presented. It is shown that computation time dominates communication time in the distributed computing model. This provid...

when a dam is constructed on a river path, inevitably sedimentation of alluvial materials occurred. therefore, the initial capacity of the reservoir reduce gradually, and if don’t predict the effects of this phenomena and its proper control methods, the application of the reservoir may be affected. the findings of this thesis confirm that, the sedimentation in reservoirs and the variations of t...

flexible ac transmission systems (facts) controllers with its ability to directly control the power flow can offer great opportunities in modern power system, allowing better and safer operation of transmission network. in this paper, in order to find type, size and location of facts devices in a power system a dedicated improved particle swarm optimization (dipso) algorithm is developed for de...
