Virtual Briefing -- February 2003 -- End-to-End Performance Measurement Systems
While current technology to assess network performance characteristics is quite primitive, there is work under way to provide tools and infrastructure that will allow us to better understand performance issues. The February Virtual Briefing will focus on current activities to determine performance capabilities in end-to-end environments and current research in new measurement systems.

'Selfish' routers slow the Internet | CNET News.com
That's the conclusion two Cornell University computer scientists came to after finding that computer networks tend to be "selfish" when each tries to route traffic by the fastest pathway, causing that path to become congested and slow.
If the routers that direct the packets of data could be programmed with some altruism, the information might be able to reach its destination a little faster while allowing other packets to also move more quickly.
Eva Tardos and Tim Roughgarden described their work on Friday in a talk titled "Selfish Routing and the Price of Anarchy," at the annual meeting of the American Association for the Advancement of Science in Denver. Their presentation was part of a symposium called "Game Theoretic Aspects of Internet Computation" which explores the application of economic principles to the Internet

A Hierarchy of Network Measurements for Grid Applications and Services -- PDF Document
DRAFT
October 4, 2002
This document describes a naming system needed for the description of network measurements useful for Grid applications and services. The goal of this work is to identify the various types of network measurements according to the network characteristic they measure and the network entity on which they are taken. The application of this naming system will facilitate the creation of common schemas for describing network monitoring data in Grid Monitoring and Discovery Services, and thus help to address portability issues between the wide variety of network measurements used between sites of a Grid.
rfc2330 - Framework for IP Performance Metrics
The purpose of this memo is to define a general framework for particular metrics to be developed by the IETF's IP Performance Metrics effort, begun by the Benchmarking Methodology Working Group (BMWG) of the Operational Requirements Area, and being continued by the IP Performance Metrics Working Group (IPPM) of the Transport Area.
DMTF - Education - The CIM Tutorial Online
The Common Information Model (CIM) is a common data model of an implementation-neutral schema for describing overall management information in a network/enterprise environment. CIM is comprised of a Specification and a Schema. The Specification defines the details for integration with other management models (i.e. SNMP's MIBs or the DMTF's MIFs) while the Schema provides the actual model descriptions.
Dubbed the "OptIPuter"-for optical networking, Internet Protocol, and computer storage and processing-the envisioned Grid infostructure will tightly couple computational, storage and visualization resources over parallel optical networks using the IP communication mechanism.

Division of Advanced Networking Infrastructure and Research
Full Proposal Deadline(s) (due by 5 p.m proposer's local time): May 08, 2003
The Networking Research Testbeds (NRT) program will create a new generation of networking technologies through the process of ideation, realization and experimentation carried out on a diverse set of research testbeds. Through this program, researchers will be able to test and refine new concepts and architectures on a number of independent testbeds that have been designed and built by networking researchers themselves. While all NRT's will emphasize cutting-edge research, each individual testbed will be designed to support activities in a defined thrust area. NRT's can therefore range in size from small campus-size testbeds to larger regional or national-scale testbeds, depending on the level of collaboration, partnership and the project mission. The underlying platform may be based on different technology components -such as wireless, fiber-optic or overlay networks - depending on the level of flexibility and control required by the associated research program. We encourage collaborative projects with highly ambitious goals and pioneering visions that step outside today's Internet-centric paradigm. Projects must contribute in a significant way to expanding the frontiers of networking through exploration of new theories and architectures, and development and testing of prototype systems.

This workshop will be an opportunity for researchers around the world to discuss and exchange experience on the performance of transport and application protocols (TCP, UDP, HTTP, FTP, etc.) over fast long-distance networks. This year, a particular emphasis will be on TCP congestion control. Each day will start with a plenary talk and end with a panel. In between, formal presentations of papers will be followed by extensive and informal Q&A sessions

Self-Configuring Network Monitor
The ultimate goal of this infrastructure is to provide accurate, comprehensive, and on-demand, application-to-application monitoring capabilities throughout the interior of the interconnecting network domains. In this project we are designing and implementing a self-configuring monitoring system that uses special request packets to automatically activate monitoring along the network path between communicating endpoints.
Here is the full report published at NSF.
The path forward that this report envisions - extensive cyberinfrastructure to enable all levels of S&E research and education, geographic and institution independence, cross-discipline sharing of data and insights, and technical depth in all dimensions, not just processor speed - truly has the potential to revolutionize all fields of research and education.
Protocol promises faster Web services - Tech News - CNET.com
A proposed method for sharing information between systems linked on the Internet promises to speed collaborative applications by up to 10 times the current rates.
The protocol, developed by Jonghun Park, a professor at Pennsylvania State University's School of Information Sciences and Technology, is based on an algorithm that lets it use parallel instead of serial methods to process requests. Such a method boosts the efficiency of how resources are shared over the Internet. The new protocol is called Order-based Deadlock Prevention Protocol with Parallel Requests.

NSF Network Research Testbeds Workshop
The NSF Workshop on Network Research Testbeds was held on October 17-18, 2002 , bringing together 23 key networking researchers to discuss the focus, needs, and hardware and software structures for a new generation of network research testbeds - testbeds that will allow for disruptive experimentation with network infrastructure, and that will enable and enhance cutting edge networking and network-application research over the next decade and beyond. The report of this workshop (see below) documents the findings and recommendations of this workshop. Given the critical role of testbeds in networking research, and the many benefits that flow from a vibrant research activity in such testbeds, workshop participants recommend that NSF initiate a significant new program to provide core funding for network research testbeds.
The end2end-interest list is currently maintained as a service of USC/ISI's Postel Center for Experimental Networking (PCEN).
The end2end-interest list is for discussion of research and design issues that are broadly related to the end-to-end aspects of computer networking protocols and architecture, and in particular the consequences of the end-to-end principle underlying TCP/IP. It is sponsored by the End-to-End Research Group, whose historical roots go back to the original ARPA-funded research project that developed the Internet architecture and protocols, and which now forms one group within the Internet Research Task Force (IRTF).
