High-performance supra-high-speed packet-switched networking using neural arbiters.

The past few years have visualized tremendous research interests along with associated breakthroughs in Optical Fiber Communications (OFCs) and Artificial Neural Networks (ANNs). The first one has resulted in the elimination of the transmission-speed bottleneck of the pre-mid-1980 era, and hence cost-effective deployment of optical fibers in both short- and long-haul telecommunication networks. And the second has led to the development of massively parallel interconnection structure with simple, i.e., of the add-compare-select type, processing elements for solving large-scale, multi-criterion decision making problems in both on-line and off-line fashions at very high speed. To utilize effectively the vast fiber bandwidth, researchers have proposed the Wavelength Division Multiplexing (WDM) technique which reduces the impact of speed mis-match between nodal processing and link transmission. Further enhancements in performance can be achieved when neurally arbitrated multi-connected regular topology--constructed using WDM--is used as the operational connection structure of any arbitrary physical topology. This dissertation deals with the development of new and efficient techniques for evaluating architecture and packet routing strategy, and enhancing performance using ANNs, of the Manhattan Street Network (MSN) which is a special kind of two-connected regular mesh topology. MSN uses uni-directional links with adjacent channels carrying packets in opposite directions. The end nodes of every row and column are directly connected using wrap-around links. A new analytical technique for evaluating the architecture of arbitrarily large MSNs in a traffic-distribution-specific manner has been developed. The validity of this technique has been verified through computer simulation. A novel simple analytical technique for evaluating deflection routing in the MSNs has also been developed. The advantage of this technique lies in the fact that although it computes the Mean Packet Transfer Time (MPTT) by simply adding the Mean Inter-Node Distance (MIND), deflection and waiting penalties, it offers a reasonable degree of accuracy as ratified by simulation. Finally, it is shown that when Grossberg\u27s ANN along with a fuzzy logic based pre-processor is used for packet route arbitration, congestion-free operation of a network can be easily achieved.Dept. of Electrical and Computer Engineering.

Impact of Virtualization and SDN on Emerging Network Coding

IETF/IRTF draftInternet DraftNetwork Coding is a technique used to code packets and be able to recover coded packets from loses. It requires at least two participating nodes in the path of the packet, one to encode and another to decode. This document discusses the impact of virtualization and Software-Defined Networking (SDN) on the emerging network coding. This document also discusses the integration of network coding in various layers of the network stack and the APIs required from the network coding entity to program it from a controller

Cloud Computing, Networking, and Services

Cloud computing, networking, and their related service (CCNS) management including grid computing (as appropriate) have recently emerged out of hypes to viable computing/networking tools for reducing infrastructure deployment and servicemanagement costswithout sacrificing the quality of service/experience (QoS/E). There are many definitions of CC; see for example, IETF Website, http://trac.tools. ietf.org/area/app/trac/wiki/Clouds and NIST website, http://www.nist.gov/itl/cloud/. The concept of CC has since been expanded to cover other types of resources as well. These resources include storage resources (DropBox, Microsoft SkyDrive, Google Drive, etc.), communications resources (software defined networking, Networkingas- a-Service or NaaS, etc.), and others. Consequently, the term CC is being commonly used for applications and services that utilize distributed virtualized computing, communications, storage, and any other resources, in general

Cooperative Management Of Enterprise Networks In A Mobile Environment

A mobile Computer Supported Cooperative Work (CSCW) environment is a natural setting for the integrated management of enterprise networks. This allows the sharing of scarce management expertise. The infrastructure for such systems is likely to proliferate soon, thanks to the rapid growth in mobile data communication systems. But these systems have severe bandwidth restrictions and have limited battery power on mobile terminals. Therefore, many of the standard clientserver applications are not suitable for a mobile environment. However, the mobile environment offers a potentially useful facility in terms of broadcasting that allows multiple experts to work together with out adding any significant overhead on the communication and computing infrastructure. This paper analyses the requirements for supporting CSCW management applications in a mobile environment. 1. INTRODUCTION The world is witnessing substantial growth in networked information systems.
