  1. Interesting Problem at Cisco DP&NM Members dpnm@tigris.postech.ac.kr Tel: 0562-279-5641 http://dpnm.postech.ac.kr Distributed Processing & Network Management Lab Dept. of Computer Science and Engineering POSTECH

  2. Dear DPNM Members Prof. Hong write: • I have received a request to see if we can investigate the following. • I would like you all to think about this and we can discuss about this at the next Lab meeting, Tuesday 4:00pm.

  3. High-Level Description: The topic we are interested in is to investigate for a particular product what it would involve to convert it from a Java-based management application into applets (i.e. into a browser-based application) from a product standpoint: i.e. technical effort involved, distribution aspects, considerations with regard to startup time and reliability, benefits/tradeoffs, etc.

  4. Detailed Description: • We have ELS/NMS cisco WAN manager which used to have a Motif-based GUI interface. We want to make the GUI web based. We are building Java application using Orbixweb. Our Java client GUI uses idl interface to talk to a C++ backend process. • We also want to make the Java application as Java applets which then can be used from a standard browser. • We would like some one to come and evaluate multiple options to do these and recommend a scaleable solution. • Currently one CWM server supports up to 40 desktops and manages networks with around 2000 nodes and around 500K PVC. When we go to web based solution, we would like to support 100's of Web Clients. • Please let me know what you can do to contribute in this area.

  5. Problem • How to convert from Java application to Java applet? (Java application using OribixWeb & C++ backend process)

  6. Problem • What problems exist in Java applet distribution and what solutions to the problem? • security, upload time, disparate JRE …

  7. Problem • How to manage scalability, with the performance point of view? • supports up to 40 desktops • manages around 2000 nodes and around 500K PVC • supports 100's of Web Clients

  8. Problem • What advantages/disadvantages does Java applet has over Java application? • No user program, real ubiquity / startup time, reliability ...
