Microsoft Backs ICE To Ease Realtime Communications-- Posted by XanTium on November 10 21:38 EST
From crn.com:
Microsoft is backing Interactivity Connectivity Establishment (ICE) technology, which the company said will facilitate secure VoIP and other realtime communications over the Web.
Microsoft is building ICE into upcoming versions of its MSN Messenger instant-messaging client and the fuller Communicator client, slated to arrive in the Office 12 time frame next fall. The ICE component also will flow into the stack of Xbox Live, Microsoft's online gaming console.
ICE, which Microsoft said is backed by Cisco Systems and a half-dozen as-yet-unnamed technology companies, launches in parallel with the Session Initiation Protocol (SIP), which typically kicks off any realtime messaging or VoIP communication.
"It sends out an ICE discovery message, saying in essence: 'I'm about to set up a realtime media [session], but I need your help. I think my IP address is thus. Tell me if it looks like my IP is thus,' " Russell Bennett, program manager for Microsoft's Real Time Collaboration Group, said.
This verification process puts the real IP address into media packet headers and assures that the realtime media flows to the right recipient.
