Definition of new attributes (TEMPLATE-ID) Definition of new operations (Creation and termination

of a conference) Definition of the errors message of the CSCP protocol New examples. 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

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.
