An access control system for a computing environment in which a number of processing nodes are interconnected to one another via an interconnection system. Multiple program applications, each made up of a number of application components, are installed in the environment, such that their components may be distributed among the various processing nodes of the platform. A set of rules is established, indicating allowed inter-node communications between the application components, and those rules are mapped onto a set of logic in the platform. The logic may be embodied in various forms, such as packet-filtering logic in a network interconnect switch, or firewall logic in a processing node. In turn, when an application component on one node attempts to communication with another application component on another node, a determination can be made whether the communication is allowed and, if the communication is not allowed, the communication can be blocked.

Method and system for communication control in a computing environment

Apparatus and methods for transferring audio between a headset and electronic equipment over an optical link. The apparatus includes an electro-optical interface for electrically connecting to the electronic equipment, an optical link, and an electro-optical headset. Audio from the electronic equipment modulates a light source in the electro-optical interface. A modulated light signal is transmitted through the optical link to the electro-optical headset where it is demodulated and reproduced as the original audio in the ear of a user wearing the headset. Also, another audio from the user's mouth produces another modulated light signal in the electro-optical headset. The other modulated light signal is transmitted through the optical link to the electro-optical interface where it is demodulated to provide the other audio to the electronic equipment. The non-electrical optical link may improve audible communications between the electronic equipment and the headset in radio-frequency noisy environments. Also, the non-electrical optical link may prevent coupling with an aerial of the electronic equipment and improve radio propagation.
