3.1 Collaboration Protocols

Collaboration protocols enable people to collaborate in desktop or browser-based workspaces to achieve their common goals. These services also provide a manageable infrastructure and extensible application platform for improving the efficiency of business processes.

Collaboration protocols provide audio and video conferencing, Instant Messaging, email, presence notification, web conferencing, whiteboarding, Voice over IP (VoIP) telephony, collaborative file transfer, content management, application-sharing and similar services through Windows or web-based consoles.

Collaboration protocols are implemented across multiple client and server products, such as Windows, Office, Microsoft Exchange Server, Windows SharePoint Services, Microsoft NetMeeting, Lync Server (previously Office Communications Server), Office Groove, and SharePoint Workspaces.
