Introduction
The Internet is evolving to support a variety of distribution models and carry a much broader range of traffic than was traditionally available, in particular multimedia services such as real time audio and video. Multicasting, a network distribution methodology which efficiently transmits data to multiple receivers, is now being widely deployed to solve some of the problems inherent in these new services.Some current uses of the MBone include distributing audio and video streams of conferences, seminars, interactive meetings, and media events. It may see increasing usage as a communication mechanism for networked multi-user 3D applications.
Production Internet routers are only recently beginning to support native multicast. The MBone was designed to provide interim support by using
virtual logical links between multicast-capable routers that cross over non-multicast capable infrastructure. Endpoints of these virtual links, or tunnels, encapsulate multicast packets into normal IP packets and route them to other multicast capable subnets over the unicast path between the tunnel endpoints. Tunnel endpoints are typically Unix workstations with IP multicast support, using the multicast routing daemon mrouted. mrouted runs a multicast routing protocol that dynamically manages a spanning tree over the links in the MBone. This tree ensures that data is sent only once across each multicast link, replicated only as necessary when the spanning tree splits into multiple paths.
PROJECT DESCRIPTION
Defining the 3D Internet
And it's clear that Internet users crave richer ways to interact. "This is the mode of communication that we're gravitating toward," says Chris Melissinos, chief gaming officer at Sun Microsystems, which offers a computing platform for running online games and virtual worlds. "It's really going to change how we communicate and view information."
3D Internet: Why?
One of the often heard arguments against the 3D Internet is in the form of the question “why do we need it?” For most of its users the Internet is a familiar, comfortable medium where we communicate with each other, get our news, shop, pay our bills, and more. We are indeed so much used to and dependant on its existence that we don’t think about its nature anymore just like we do not think about Ohm’s law when we turn on the lights.
3D Internet: What?
3D Internet shares the time-tested main principles and underlying architecture of the current Internet as well as many semantic web concepts. The operational principles the 3D Internet shares with its predecessor include open and flexible architecture, open protocols, simplicity at the network core, intelligence at the edges, and distributed implementation. We adopt here the terms universe, world, and webplace as 3D counterparts of WWW, website, and sub domain, respectively. We describe each component’s functionality briefly below:
