What is network connections?
I have a file that appears sometimes in processes running and once Adobe Photoshop said rndal.exe did not initialize. It says it is a RealNetwork Dynamic file and an update from 2003. What is RealNetwork Dynamics? Rea etc. also keeps trying to access the internet which I have denied.
Microsoft Help had no info. Thanks for anything you can provide. Judy
This question was answered on October 30, 2004. Much of the information contained herein may have changed since posting.REAL is a network simulator originally intended for studying the dynamic behaviour of flow and congestion control schemes in packet-switched data networks It provides users with a way of specifying such networks and to simulate their behavior It provides around 30 modules (written in C) that exactly emulate the actions of several well-known flow control protocols (such as TCP), and 5 research scheduling disciplines (such as Fair Queueing and Hierarchical Round Robin) The modular design of the system allows new modules to be added to the system with little effort Source code is provided so that interested users can modify the simulator to their own purposes Online documentation and source code are part of the distribution.
The simulator takes as input a scenario, which is a description of network topology, protocols, workload and control parameters It produces as output statistics such as the number of packets sent by each source of data, the queueing delay at each queueing point, and the number of dropped and retransmitted packets This release includes a graphical user interface (GUI) written in Java by Hani T Jamjoom at Cornell University.The GUI allows users to quickly build simulation scenarios with a point-and-click interface For more details, please see the RealEdit home page.
The GUI also allows scenarios to be simulated on a server generously loaned to Cornell University by Digital Inc This makes it unnecessary for users to download, compile and build the simulator in order to run simulations Instead, the scenarios, once created, are shipped to the server for execution, and the results are shipped back to the GUI for display.
REAL is written in C, and will run on Digital Unix/ SunOS/ Solaris/ IRIX/ BSD4.3/Ultrix /UMIPS systems on VAX, SUN, SPARC, MIPS, Alpha, SGI or DECstation hardware For a full list, see the Installation manual The simulator has been ported by Warren Toomey and Elan Amir to the i386/FreeBSD 2.0.5 platform Click here to get their patches to REAL, or ftp them from ftp://minnie.cs.adfa.oz.au/pub/www/REAL/Real_FreeBSD.tar.gz.
REAL manuals can be found here The Installation manual will help you install the simulator in your local environment The User manual is a step-by-step tutorial on using REAL for beginning users The Programmer's manual is a tour of the files in REAL, and a cookbook for modifying REAL and Nest.
An early description of REAL is in Computer Science Department Technical Report 88/472, UC Berkeley, 1988 It gives an overview of REAL and some examples of network analysis using REAL For copies send mail to Anne Fuller, Office Supervisor, [email protected] For a description of the changes made in REAL 5.0 compared to REAL 4.0, please see the changes page
