NTT announces that it started to run experiments in a joint effort with other organizations on Photonic architectures for Internet Exchanges (IX).
The recent wide penetration of high-speed Internet has caused rapid growth in the amount of communication information (traffic). Subsequently, this has raised the issue of a shortage in the circuit capacity. In particular, the increased amount of traffic is concentrated at the IXes of multiple Internet Service Providers (ISPs) posing a significant problem.
The press-release says that based on the trend in the total amount of traffic of the three major IXes in Japan, the total amount of traffic has been increasing two-or-three-fold every year, and at the end of the first half of 2004 the level has reached the 90 Gbit/s traffic (average per month) level. A novel IX architecture is therefore needed in order to cope effectively with the increasing amount of traffic.
The Photonic IX is characterized by its architecture, which allows for interworking between IP Routers and Layer-2 switches, both of which the ISP and IX have operated so far, and GMPLS-enabled OXCs, which NTT newly developed.
More hardcore technical details which are over my head in NTT announcement. I am just for a faster Internet!
