Chapter 1: What's New in RealServer G2?

RealServer G2 is designed on a new architecture that allows greater extensibility and interoperability with third-party solutions.

New Features

In addition to the improvements added to RealSystem G2, RealServer G2 includes many new features.

License Files

Previous versions of RealServer used an encrypted license key string, which was used during installation and placed in the configuration file, to indicate which features were available.

RealServer G2 introduces new license files that allow for greater flexibility in upgrading available features.

Additional Information
See "License Information".

RealSystem Administrator

RealServer G2 includes RealSystem Administrator, a new HTML interface for working with nearly every aspect of Server operations. Use this tool to fine-tune RealServer features, monitor Server activity, and play sample presentations.

RealSystem Administrator can be accessed from any Web browser on the network. Security features for RealSystem Administrator are also included.

Additional Information
See "Customizing RealServer".

New Protocols

RealServer G2 now uses RealTime Streaming Protocol (RTSP) as its control protocol and RealNetworks' proprietary RDT as its packet protocol.

New URL Format

A visible change in this version of RealServer is the change in URLs that point to RealServer presentations.

New Configuration File Format

The configuration file, which stores all the settings used by the RealServer, is now in Extensible Markup Language (XML) format. This new format allows greater flexibility and extensibility by third parties. The file is easy to modify with the new RealSystem Administrator, or you can still use a text editor to make changes.

Additional Information
See Chapter 4: Customizing RealServer Features.

Open Architecture

Most features are handled by separate files, called plug-ins. Located in the plug-ins directory, these plug-ins are read by RealServer when it starts and they control what happens to client requests. The RealServer open architecture allows third-party companies to develop plug-ins that can be added easily to RealServer for future functionality. This open architecture lends itself to modularity and customizability.

Additional Information
See Chapter 4: Customizing RealServer Features.

New Splitting Method

In addition to the splitting method of previous versions, splitters can now rebroadcast material upon request.

Additional Information
See "Pull Splitting".

Control Access to Ports Based on IP Address

RealServer G2 allows you to limit access to RealServer based on the IP address of the requesting client just as earlier versions did, but RealServer G2 adds the ability to restrict access to certain ports. In this way, you can better control traffic flow on your RealServer computer.

Additional Information
See "Limiting Access Via IP Address".

Authentication

New options for verifying the identity of visitors to your RealServer presentations include Windows NT authentication.

Additional Information
See Chapter 10: Authenticating RealServer Visitors.

New Monitoring Methods

Use the constantly updating G2 Java Monitor in RealSystem Administrator. Zoom in for a closer look. Change the colors of the display.

Additional Information
See "G2 Java Monitor".

If you have Windows NT, use the NT Performance Monitor with the RealServer rmserver.pmc file.

Additional Information
See "Using Windows NT Performance Monitor".

Integration with Windows NT User Groups

RealServer works with Windows NT User Authentication to give access to users who are already in the NT user group lists.

Additional Information
See "Windows NTLM Challenge/Response".

Compatibility With Previous Releases

RealServer G2 is fully compatible with RealServer 3.0 through 5.0:

To use new features, such as RealText, in an existing presentation, you must update the presentation by creating a SMIL file and modifying the URL that refers to the presentation.
