Ultra long haul solution offers up to 3000 Km distance without regeneration
UTRECHT, NETHERLANDS, MARCH 9 — Cisco today announced that SURFnet has completed a technology test of Cisco's 100G DWDM solution between the National Supercomputing Center, SARA, in Amsterdam, the Netherlands, and CERN in Geneva, Switzerland, using the Cisco ONS 15454 M6 Multiservice Transport Platform. The Cisco system uses dense wavelength-division multiplexing (DWDM) to unite multiple optical carrier signals on a single optical fiber, leading to several benefits including increased fiber capacity.
SURFnet enables collaboration between researchers, teachers, and students in the Netherlands using information and computing technology and together with partners offers high speed communication services between leading innovation centers and universities in Europe and throughout the world.
The test involved introducing 100G single carrier optical interfaces into SURFnet's existing optical infrastructure made up of a combination of 10G, 40G and 100G wavelengths. Once connected, the Cisco 100G DWDM solution was quickly operational without any disruption to the existing network. This demonstration shows that SURFnet can utilize its existing infrastructure and help protect its network investment while supporting new 100G data services over the existing fiber infrastructure. Utilizing this type of 100G technology allows research and education networks such as SURFnet to use its existing 50GHz spectrum band more efficiently and provide cost-effective all-optical connectivity across international borders.
This demonstration is another example of SURFnet's commitment to technology that supports the rapid growth of new applications and services in the international NREN community. This evaluation also showcases Cisco's ability to offer 100 Gigabit technologies that meet the needs of the Next Generation Internet for core, edge, data center, and transport.
"This 100G alien wavelength demonstration is another important step in the future of international networking across geographical, technical and administrative borders. Being able to use high-bandwidth wavelengths over open transmission systems from different equipment vendors supports new approaches to networking. The use of all-optical alien wavelength 100G technology is what will enable cost-effective international research networking."
"Service providers around the globe see the need to get prepared for the next internet, including an increased demand for video, collaboration, and distributed computing and SURFnet is no exception. SURFnet's successful evaluation shows that Cisco is ready to deliver the network foundation for the Next Generation Internet."
SURFnet is the National Research & Education Network (NREN) organization in The Netherlands. SURFnet develops and provides innovative services for education and research in the field of a hybrid network infrastructure, trusted identity and a pioneering collaboration environment. SURFnet provides access to these services to over one million users in higher education and research in The Netherlands. SURFnet is part of SURF, the collaborative organization for higher education institutions and research institutes, which are together working on breakthrough innovations in ICT.

Researchers from the Suddhananda Engineering and Research Centre in Bhubaneswar, India developed a job scheduling system, which they call Service Level Agreement (SLA) scheduling, that is meant to achieve acceptable methods of resource provisioning similar to that of potential in-house systems. They combined that with an on-demand resource provisioner to ensure utilization optimization of virtual machines.
Experimental scientific HPC applications are continually being moved to the cloud, as covered here in several capacities over the last couple of weeks. Included in that rundown, Co-founder and CEO of CloudSigma Robert Jenkins penned an article for HPC in the Cloud where he discussed the emergence of cloud technologies to supplement research capabilities of big scientific initiatives like CERN and ESA (the European Space Agency)...
When considering moving excess or experimental HPC applications to a cloud environment, there will always be obstacles. Were that not the case, the cost effectiveness of cloud-based HPC would rule the high performance landscape. Jonathan Stewart Ward and Adam Barker of the University of St. Andrews produced an intriguing report on the state of cloud computing, paying a significant amount of attention to the problems facing cloud computing.
