CSCP draft is completely updated and alinged with: BFCP (draft-ietf-xcon-bfcp-06.txt ) draft Connection Establishment in the BFCP (draft-ietf-xcon-bfcp- connection-00.txt) draft

3. 3 Some Advantages of CSCP Based on BFCP Reduces the number of protocols required to be supported by clients and servers in the conference. It can modify the "variable" data and the "common" data using the same operations. The extension of the " variable" or " common " data does not imply the extension of the CSCP protocol. Easy to implement. Work properly in all kind of environment, for instance, wireless. Small message size, therefore, small amount of time to retransmit the message.
