[e2e] Software release of JavaSim 1.0

* Apology if duplicate copies are received *

We are pleased to announce the (long overdue) public release of JavaSim.
JavaSim, based on JDK 1.3, combines some of the latest innovations in
network modeling and simulation research.

The current version for JavaSim (v1.0) is available for download from

        http://javasim.cs.uiuc.edu/
        http://www.javasim.org/

JavaSim includes the following features:

  * A loosely coupled component architecture that decouples component
    binding from contract binding.  Components can be designed,
    implemented, and tested in isolation of the rest of the system.

  * A generic network modeling framework that is general enough to
    accommodate new network architectures. New algorithms/protocols
    can be easily implemented and inserted.

  * An innovative real-time process-driven simualtion technique that
    simulates real systems realistically.

  * An essential set of network components for composing network
    simulation scenarios in the best-effort, integrated, and
    differentiated services architecture, as well as mobile ad hoc
    environments.

  * A dual-language environment in which Java is used to implement
    network components and a script language is used as the glue that
    integrates and configures components at run time.  Currently Tcl and
    Python are supported.

  * Fidelity of simulation results has been validated through comparison
    against results obtained from ns-2 and well-known theoretical results.

  * Rich utility functions and plotting tools to facilitate on-line
    monitoring and display of simulation results.

  * With smaller memory footprint, JavaSim exhibits better scalability
    than ns-2 (SSFNET) in network simulation scenarios of more than 10,000
    <4,000) nodes (on a PC with dual Pentium III 6000 MHz and 256 MByte
    RAM).

The JavaSim developers can be reached at javasim at cs.uiuc.edu. JavaSim
announcements are available by subscribing to the javasim-announce mailing
list To subscribe, send a mail to javasim at cs.uiuc.edu with the body
"subscribe javasim-announce"

The project has been supported in part by National Science Foundation,
DARPA/ITO (Quorum and NMS), MURI, Ohio Stateuniversity and University of
Illinois at Urbana-Champaign.

We look forward to feedback from users of JavaSim.
