Software components

The software consists of two components: the InterGroup node and the RSGC client. The InterGroup node provides the core functionality of the system and must be run on a multicast-enabled host. The RSGC client connects to the InterGroup node via TCP and provides the APIs to the system.

System Requirements

InterGroup node

In order to run the InterGroup node you must have a Java^TM virtual machine (JVM) installed on your system. The InterGroup node is designed to work with JVMs that support Java^TM 2 Platform, Standard Edition (J2SE^TM) version 1.3 or higher.

This version of the InterGroup node has been tested on the following system configurations:

• SPARC architecture/SunOS 5.7/Sun JDK 1.3.0
• SPARC architecture/SunOS 5.7/Sun JDK 1.4.0
• Intel architecture/Windows 2000/Sun JDK 1.4.0-beta3
• Intel architecture/Linux Mandrake release 7.2 (Odyssey) for i586 - kernel 2.4.17-w /Sun JDK 1.3.1
• Intel architecture/Linux Red Hat release 7.2 (Enigma) - kernel 2.4.9-13/Sun JDK 1.3.1_02

For information on obtaining and installing a JVM on your system please visit the Java Technology Products and APIs page (for Solaris, Windows and Linux operating systems) or the Java Platform Ports page (for other operating systems).

RSGC client

The RSGC client is available in Java, C++ and Python. The system requirements for the Java client are the same as for the InterGroup node.

The C++ client depends on the dsds (Distributed Systems Department Shared) library, the requirements for this library to compile and to work are:

• GNU g++ 3.x or higher.
• The POSIX thread library pthread.
• The BSD socket library (with the latest api).
• pkg-config.

• The cppunit library for the unit tests to work.
• The openssl library for the security feature of dsds and SGL (Secure Group Layer in rsgc)

This version of the C++ client has been tested on the following system configurations:

• SPARC architecture/SunOS 5.8
• Intel architecture/Linux Red Hat releases 7.3, 8.0, 9.0
• Intel architecture/FreeBSD release 5.x
• Intel architecture/Windows XP Pro

The Python client is a SWIG wrapping of the C++ client code, so it depends on the C++ client. It has been tested with Python 2.2. This is an early release version.
