The Network Simulator ns-2: Topology Generation Topology generation is required for network simulations. In NS-2 you may create a topology for simulation using one of the following methods: by using the Inet topology generator. by using the GT-ITM topology generator. by using the Tiers topology generator. by using the other topology generators. by hand Inet Topology Generator Generating graphs from Inet topology generator Download the Inet Topology Generator from University of Michigan and create a internet topology using the configuration parameter. Conversion of Inet output to ns-2 format Use to convert the inet topology to ns. The command to execute the script is: inet2ns ns.topology Georgia Tech Internetwork Topology Models Generating graphs from GT-ITM topology generator. Download the GT-ITM Topology Generator software. The GT-ITM topology generator can be used to create flat random graphs and two types of hierarchical graphs, the N-level and transit-stub. Take a look at the examples in Daniel Zappala's homepage . Also look at the documents under docs subdirectory of GT-ITM's distribution. For example, we need to create a transit-stub graph with 200 nodes. So we create a specification file, say ts200, that goes like this:

The Geometry and Topology of Three-Manifolds by William P. Thurston Electronic version 1.1 - March 2002 - with an index! http://www.msri.org/publications/books/gt3m/ This is an electronic edition of the 1980 lecture notes distributed by Princeton University. The text was typed in TeX by Sheila Newbery, who also scanned the figures. Typos have been corrected (and probably others introduced), but otherwise no attempt has been made to update the contents. Genevieve Walsh compiled the index. Numbers on the right margin correspond to the original edition's page numbers. Thurston's Three-Dimensional Geometry and Topology , Volume 1 ( Princeton University Press , 1997) is a considerable expansion of the first few chapters of these notes. Later chapters have not yet appeared in book form. Please help improve this document by sending to Silvio Levy at levy@msri.org any useful information such as reports of typos, omissions, and departures from the printed notes that are not purely stylistic references for results attributed without citation references to solutions of then-open problems HERE IS THE STUFF I've broken it down into chapter or portions about 20 pages long.

The model is animated to show how traffic flows over the links. More information on their work can be found in the paper "Network Performance Visualization: Insight Through Animation" by J.A. Brown, McGregor A.J and H-W Braun. These striking images are 3D hyperbolic graphs of Internet topology. They are created using the Walrus visualisation tool developed by Young Hyun at the Cooperative Association for Internet Data Analysis ( CAIDA The underlying data on the topological structure of the Internet is gathered by skitter , a CAIDA tool for large-scale collection and analysis of Internet traffic path data.

50. Network Topology Introduction Get Computer network topology overview and learn how computers get connected, physical and logical design. http://www.networktutorials.info/topology.html

Configure a Network Communication Devices IT Certifications Computer Glossary ... Links An Overview of Computer Network Topology Physical Topology means the physical design of a network including the devices, location and cable installation. Logical Topology refers to the fact that how data actually transfers in a network as opposed to its design. Topology can be considered as a virtual shape or structure of a network. This shape actually does not correspond to the actual physical design of the devices on the computer network. The computers on the home network can be arranged in a circle shape but it does not necessarily mean that it presents a ring topology. Computer network topologies can be categorized in the following categories. Hybrid networks are the complex networks, which can be built of two or more above mentioned topologies. Bus Topology Bus topology uses a common backbone to connect all the network devices in a network in a linear shape. A single cable functions as the shared communication medium for all the devices attached with this cable with an interface connector. The device, which wants to communicate send the broadcast message to all the devices attached with the shared cable but only the intended recipient actually accepts and process that message.

51. Open Problems In Algebraic Topology Problems in algebraic topology, listed by Mark Hovey, mathematician at Wesleyan University. http://claude.math.wesleyan.edu/~mhovey/problems/

Mark Hovey's Algebraic Topology Problem List This list of problems is designed as a resource for algebraic topologists. The problems are not guaranteed to be good in any wayI just sat down and wrote them all in a couple of days. Some of them are no doubt out of reach, and some are probably even worseuninteresting. I ask that anybody who gets anywhere on any of these problems, has some new problems to add, or has corrections to any of them, please keep me informed (mhovey@wesleyan.edu). If I mention a name in a problem, it might be good to consult that person before working too hard on the problem. However, even if the problems we work on are internal to algebraic topology, we must strive to express ourselves better. If we expect our papers to be accepted in mathematical journals with a wide audience, such as the Annals, JAMS, or the Inventiones, then we must make sure our introductions are readable by generic good mathematicians. I always think of the French, myselfI want Serre to be able to understand what my paper is about. Another idea is to think of your advisor's advisor, who was probably trained 40 or 50 years ago. Make sure your advisor's advisor can understand your introduction. Another point of view comes from Mike Hopkins, who told me that we must tell a story in the introduction. Don't jump right into the middle of it with "Let E be an E-infinity ring spectrum". That does not help our field. Here are the problems: Major problems in the field Morava K- and E-theory Elliptic cohomology Applications ... Miscellaneous Unstable modules and algebras over the Steenrod algebra (coming soon)

Paolo Salvatore University of Rome Tor Vergata A topological version of the cyclic Deligne conjecture The Deligne conjecture states that the Hochschild complex of an associative algebra admits the action on the chain level of the little discs operad. McClure-Smith proved a topological version, with the Hochschild complex replaced by the totalization of an operad in based spaces. I will show that a cyclic operad in based spaces yields an action of the framed little discs. I will present various examples and in particular an application to spaces of embeddings. David BenZvi University of Texas at Austin Real Lie Groups and Derived Algebraic Geometry I will discuss joint work in progress with David Nadler, in which we apply homotopical techniques to study representations of real Lie groups. Our main result recovers the categories of Harish-Chandra modules for real Lie groups completely formally from their much simpler complex counterparts. In particular this allows us to prove Langlands duality results for real groups by "base-change" from the known results for complex groups.

Order Parameters, Broken Symmetry, and Topology James P. Sethna Laboratory of Atomic and Solid State Physics, Cornell University, Ithaca, NY, 14853-2501 Abstract: We introduce the theoretical framework we use to study the bewildering variety of phases in condensed-matter physics. We emphasize the importance of the breaking of symmetries, and develop the idea of an order parameter through several examples. We discuss elementary excitations and the topological theory of defects. Paper published originally in 1991 Lectures in Complex Systems, Eds. L. Nagel and D.

At least one was ``plasma'', which made up stars and thus

Aims and Scope Instruction to Authors Preparation of Manuscripts TAIA Home ... Topology and its Applications is a research journal devoted to many areas of topology, and is published by Elsevier Science B.V. in Amsterdam. The journal, which began in 1971, has published over one hundred volumes. The Editors-in-chief of the journal are Professor Jan van Mill (Amsterdam) and Professor Jerry E. Vaughan (Greensboro). They and four managing editors will handle submissions. The journal will publish 27 issues in 2004; an issue contains about 110 pages. Aims and Scope of the Journal The journal is primarily concerned with publishing original research papers. However, a limited number of carefully selected survey or expository papers will also be included. The mathematical focus of the journal will be that suggested by the title, research in topology. It is felt that it is inadvisable to attempt a definitive description of topology as understood for this journal. Certainly the subject includes the algebraic, general, geometric, and set-theoretic facets of topology as well as areas of interaction between topology and other mathematical disciplines, e.g., topological algebra, topological dynamics, functional analysis, category theory, etc. Since the roles of various aspects of topology continue to change, the non-specific delineation of topics serves to reflect the current state of research in topology. The journal occasionally publishes "Special Issues." Typically these are centered around a particular topic, research related to the works of an individual, or papers presented at a focused research conference. There is a list of

Sign Up Now! Bus, ring, star, and other types of network topology In networking, the term "topology" refers to the layout of connected devices on a network. This article introduces the standard topologies of computer networking. Topology in Network Design One can think of a topology as a network's virtual shape or structure. This shape does not necessarily correspond to the actual physical layout of the devices on the network. For example, the computers on a home LAN may be arranged in a circle in a family room, but it would be highly unlikely to find an actual ring topology there.
