Technological Study of High Speed Networks – The INTERNET2
Abstract

In current Indian scenario whenever it is required to access very large amount of data such as games or some commercial applications through commodity internet (internet1), speed becomes hurdle. It becomes tolerable for some applications but no one wants to bother in case of education and research. Now the world becomes commercialized and don’t want to bother with speed. Therefore the next generation of Internet infrastructure known as Internet2 or UCAID (University Corporation for Advance Internet Development) for 21st century comes in the focus of scientists, to improve quality of life through research and education. Internet2 provides for the U.S. research and education community a dynamic, innovative and cost-effective hybrid optical and packet network. The network is designed to deliver next-generation production services as well as a development platform for new networking ideas and protocols. Built on standards based technologies and protocols, the infrastructure supports a wide range of both IP and optical services—from leading-edge IPv4, IPv6 and multicasting to static and dynamic point-to-point circuits.
In this paper, thorough analysis and comparative study of various educational networks, market scenario and Internet2 has been done, so all pros and cons become visualized to get the effect of internet2 in industries, research and development.
Keywords: Internet2; Abilene network; gigapops; high speed networks.
1. Introduction
Internet2 is a second generation network serving universities and research institutes by moving the data at a rate of 10 gigabits per second and more ,compared with 5.1 or so megabits old fashioned commodity internet. Internet2 moves data 100 to 1,000 times faster than internet1. Its gigapop (gigabit point of presence) provide regional high-performance aggregation points; for member institutions, typically local campus networks provide no less than 100 Mbps to the desktop. The team included scientists from AMD,Cisco, Microsoft Research, Newisys and S2io transfer large amount of data at a rate of 6.63 gigabits per second between distances of 9,800 miles. Now Internet2 transfer data at 9.08 gigabits per second over a distance of 30,000 km from a period of five hours [9]. What makes internet2 so different to internet1 is that it has fewer users and much faster connection. Abilene network which is designed to support high bandwidth and low latency provides a networking infrastructure tointernet2. Abilene is a dual stack IP V4/IP V6 U.S cross country network that blast bandwidths up to 10Gbps. It is designed to provide most favorable performance to both IP V4/IP V6 packets. Internet2 connects more than 200 universities, 115 private and government agencies and a lot of international organizations log on to internet2 everyday.
The main objectives [3] of using Internet2 are as follows:
To provide a common bearer service to support new applications as well as the existing ones.
To provide best effort packet to a differentiated communications service.
To provide the capabilities of network service characteristics to meet the requirement of specific
applications.
To get a high speed communications infrastructure for the Research and Education communities.
2. Why Internet2
Internet2 or UCAID were not only created to make a faster alternative to the internet. Abilene network is used for more diverse applications to provide creativity, education and research that were not possible before internet2. One of the most impacting uses of internet 2 is the robust videoconferencing between experts of different fields at a very high resolution with no noticeable time lag. If you are doing videoconferencing then you definitely need very high speed connectivity so that you can refresh the environment and react earliest to the participant on the other hand without any time lag and internet serves your demand. The purpose of internet2 is not only providing high speed but also to achieve innovation in research and distance learning through the contribution of government agencies, technologies firms and other corporate partners. By using the internet2 we bring forward the most advance networks for the university community and able to get access the peoples that would not be possible with commodity internet.
3. Internet1 Vs Internet2
Internet1 or internet simply refers to a network of computers .The base of internet1 was ARPAnet, and is developed for communication of computers over a network by Defense Advanced Research Project Agency. Internet is open to anyone with a computer and capped with a old telephone line with a speed of 4 megabits or so. The internet was first developed to use by government and universities, such institutions cope up with internet’s bandwidth limitations so they realized the need of high bandwidth network for their computer intensive work.
Internet2 is a consortium created the Abilene network for develop and deploy advanced network application. Internet2 is a noncommercial prototype of internet1 it support research, universities and agencies at a speed of 10 gigabits per second and more. The backbone of internet2 is made up of large-capacity fiber optic cables. Unlike Internet1 it has much fewer users and much faster connection. Internet1 is also comprises servers, routers and switches. The limiting factor includes the fastest available interface for home PC’s is the PCIX64 bus Isolation extender, which works only at 7.5 Gbps.
