MADCAP

Purpose

MADCAP, or Multicast Address Dynamic Client Allocation Protocol, is a technology aimed at making it easy for clients to renew and release Multicast addresses, enabling clients to dynamically "connect" and "disconnect" from multicast network transmissions.

The development of standards for MADCAP is ongoing, and falls under the Multicast Address Allocation (malloc) Working Group at the IETF.

Where Applicable

Developers can use MADCAP to:

• Dynamically obtain a multicast address for a client, enabling that client to participate in network multicast transmission reception.
  
  
• Enumerate the available MADCAP transmissions available from a given server.
  
  
• Release multicast addresses when appropriate.

The Microsoft®Windows® 2000 implementation of MADCAP adheres to the MADCAP recommendations published by the IETF, which are available on the IETF web site (www.ietf.org). Since MADCAP has not been ratified as an RFC, and is rather in Internet Draft form, the technology is subject to growth and evolution. Microsoft Corporation is actively involved with the standards process on an ongoing basis.

Developer Audience

MADCAP is designed for use by C/C++ programmers. Familiarity with Windows networking and multicast technology is required.

Run-time Requirements

MADCAP requires Windows 2000.
