What is an advanced network?
• An Advanced Network is a very high speed An Advanced Network is a very high speed communications network of regional “meet me” points communications network of regional “meet me” points (referred to as GigaPoPs) that are in turn linked to (referred to as GigaPoPs) that are in turn linked to international networks. international networks.
• They typically use optical fibre infrastructure as They typically use optical fibre infrastructure as opposed to copper wire telephone network systems opposed to copper wire telephone network systems such as those used by ADSL (Asymmetric Digital such as those used by ADSL (Asymmetric Digital Subscriber Line).Subscriber Line).
• Advanced Networks are also know as Next Advanced Networks are also know as Next Generation Internet (NGI) networks and, in the USA, Generation Internet (NGI) networks and, in the USA, as Internet2.as Internet2.
What makes an AN different?
• An Advanced Network offers significantly greater An Advanced Network offers significantly greater access speed:access speed:– Dial up connection - around 50kbit/sec (50,000 bits per Dial up connection - around 50kbit/sec (50,000 bits per
second)second)– 'High Speed' internet - typically 2.5Mbit/sec (2.5 million bits 'High Speed' internet - typically 2.5Mbit/sec (2.5 million bits
per second)per second)– Advanced Network - from 1Gigabit/sec (1000 million bits per Advanced Network - from 1Gigabit/sec (1000 million bits per
second) forecast to rise to around 40Gbit/sec within the next second) forecast to rise to around 40Gbit/sec within the next few years. few years.
How is this like PROBE?

bringing the benefits of improved connectivity. bringing the benefits of improved connectivity. PROBE is doing just this for around 2700 schools PROBE is doing just this for around 2700 schools and communities, particularly rural ones through the and communities, particularly rural ones through the provision of high speed Internet access (initially a provision of high speed Internet access (initially a minimum of 512kbit/sec with scope for expansion for minimum of 512kbit/sec with scope for expansion for secondary schools to 4Mbps) to many schools. It is secondary schools to 4Mbps) to many schools. It is anticipated that users of both PROBE and the anticipated that users of both PROBE and the advanced network could be linked together in the advanced network could be linked together in the future.future.

What is an UFN?
"The envisaged urban fibre networks will be 'open access' to encourage competitive and innovative services and should provide two-way data transfer rates of at least one Gigabyte a second - about 250 times current maximum broadband ADSL download speeds,"

What is grid computing
Grid differs from the Grid differs from the Internet as it is much Internet as it is much more than a means of more than a means of communication between communication between computers. Contrarily, computers. Contrarily, today's Internet and today's Internet and Web technologies Web technologies address basic address basic communication communication requirements, but not requirements, but not the computational tasks.the computational tasks.
