National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Resource Optimization in Hybrid Note Networks with 100G Systems, Period Covered by the Report: Sep. 1, 2009-Feb 28, 2013.

DE141133374

Publication Date	2009
Personal Author	Veeraraghavan, M.
Page Count	13
Abstract	Discuss (i) how the research adds to the understanding of the area investigated; (ii) the technical effectiveness and economic feasibility of the methods investigated; and (iii) how the project is otherwise of benefit to the public. The discussion should be written in terms understandable by an educated layman Research-and-Education Network (REN) providers have deployed both connectionless IP-routed and dynamic circuit networks. The objective of this project is to determine how these two networks can be integrated in a manner that offers both resource optimization and user-performance improvements. This will allow an integrated packet/circuit network to scale better to multi-Terabits/sec capacities as will soon be required to support the high-performance networking needs of DOE scientists. The first solution investigated, Hybrid Network Traffic Engineering System (HNTES 1.0), was an online method for identifying long-duration flows arriving on the IP-routed network, and then setting up a dynamic circuit to redirect these flows to the high-speed circuit network. We changed our focus to size from duration after recognizing that long-duration flows may not be high in the rate dimension. Instead, high-rate flows are often generated by data transfer nodes dedicated to moving large-sized datasets, and high-rate flows are the ones that can have adverse effects on delay-sensitive flows. Furthermore, the need to port mirror packets to a server cluster in HNTES 1.0 for online detection of heavy-hitter flows could be cost-prohibitive.
