Architecture - The Office Communications Server 2007 architecture

January 29, 2008
Architecture - The Office Communications Server 2007 architecture can consist of four main components—Front End Servers, perimeter servers, application servers, and Active Directory servers. We have added Conferencing Server since it is a required part of an OCS installation.  Front End Servers manage connection processing, security and authentication, protocol processing, conference creation, conference management, and the hosting of optional third-party applications.  When users sign in (logon-login) from their client devices/applications, they are registered with the Front End Server pool. The Front End Server controls both incoming and outgoing calls made by the Office Communicator clients.  The Front End Server translates the dialed number into canonical format, applies dialing authorization, and selects the appropriate IP-PSTN gateway to route calls.    Prior to any security procedures the SIP message MUST be converted into MIME-Multipart Internet Mail Extension format. MIME is a standard that allows the embedding of arbitrary documents and other binary data of known types (images, sound, video, and others) into e-mail handled by Internet electronic mail interchange protocols.
 
The Front End Server also indexes the SQL Server 2005 database to translate (map-resolve) the normalized (canonical) number to a user URI-Uniform Resource Indicator. Note: URI refers to the complete SIP telephone address not just the mail URL-Uniform Resource Locator.  If the Front End Server does not receive an acknowledgement from any one of the SIP clients of the call recipient, the configured InfoAgent or Outbound Router logic running on the Front End Server detects that the call recipient is not answering the call.
