The Current Status of the Next Generation Internet Initiative


The vBNS is so highly integrated with NGI plans, the status of the vBNS can represent the status of the NGI. Although the vBNS is not yet officially affiliated with the NGI Initiative, it is probably only a matter of time before a formal agreement is made.

The vBNS currently has a high performance OC-12c network as well as a stand-alone OC-12c test network. The OC-12 network is stable, has high throughput, and is uncongested with an average utilization of less than 50%. It has high-speed connections with both Federal and International NSF designated R&E networks, as well as network traffic and performance monitoring. A diagram of the network can be seen Here. This picture was created by the vBNS; you may not want to view it if you have a slow connection, because it is rather large.

The vBNS also supports advanced routing services. The vBNS utilizes Asynchronous Transfer Mode (ATM) and Synchronous Optical Network (SONET) to attain high speeds. ATM and SONET are advanced switching and fiber optic transmission technologies which, when combined, enable very high speed and very high capacity "on demand" transmissions of combined voice, data, and video signals. The high speeds attained by the vBNS are enabled by the connection of Internet Protocol (IP) through an ATM switching matrix, run through a SONET network.
