This document discusses the capabilities and benefits of the Internet2 network. It notes that Internet2 has much higher capacity than previous networks, with initial capacity of 10 times faster and the ability to support 10 gigabit wavelengths with future unlimited capacity. This high-speed network allows for real-time collaboration, remote access to expertise, and authentic learning experiences through high-quality video interaction. The Internet2 network acts as a community asset for universities, researchers, K-12 education, and industry both domestically and internationally.

1. Mission-critical applications seldom pursued on the public Internet Authentication “Best efforts” not good enough Intranets and Extranets instead Match capacity and demand Provide a more secure environment Don’t reach the public at large, though! 5/5/98 Today’s Internet

2. Hybrid optical and IP network Dynamic and static wavelength services Fiber, equipment dedicated to Internet2; Level 3 Communications maintains network and service level Simultaneous support of diverse requirements experimental projects production services Internet2 Network Characteristics

3. Initial capacity 10 x previous network 10 wavelengths at 10 Gbps each Future capacity nearly unlimited 40 Gbps and 100 Gbps wavelength capabilities Unlimited additional wavelengths available Rapid provisioning of dedicated circuits Flexibly-sized circuit capacity New Internet2 Network Capacities
