Architecture
The Phase 2 Video Share solution consists of a Client Application running on mobile handsets and an Application Server deployed in the mobile network. The Phase 1 Video Share architecture does not include an Application Server, i.e. media is transferred directly between the terminals. The Video Share service uses the standard IMS Core infrastructure to transmit signaling and media traffic. IP Packet Exchange (IPX) proxies may be part of this infrastructure to allow interconnection between operators and to provide a collection point for session accounting records used for inter-operator traffic charging.

Famous quotes containing the word architecture:
“For it is not metres, but a metre-making argument, that makes a poem,—a thought so passionate and alive, that, like the spirit of a plant or an animal, it has an architecture of its own, and adorns nature with a new thing.”
—Ralph Waldo Emerson (1803–1882)
“All architecture is great architecture after sunset; perhaps architecture is really a nocturnal art, like the art of fireworks.”
—Gilbert Keith Chesterton (1874–1936)
“Polarized light showed the secret architecture of bodies; and when the second-sight of the mind is opened, now one color or form or gesture, and now another, has a pungency, as if a more interior ray had been emitted, disclosing its deep holdings in the frame of things.”
—Ralph Waldo Emerson (1803–1882)
