Experts on Lambda Networking to Meet in Prague

Prague, 25 September 2015. From Monday 28 to Wednesday 30 September, the GLIF 2015 – a congress of the international consortium supporting lambda services – will take place at the Hotel International Prague. Lambda services provide very fast and secure data transmission in a point-to-point topology. They are implemented via purely optical segments linked electronically, so they use conversion of optical signal to electrical and back (OEO conversion).

The GLIF (Global Lambda Integrated Facility) provides lambda services on an international scale in the form of an integrated environment aiming at supporting data-intensive scientific research and development of middleware for lambda networking. It combines leading global experts in networking who collaborate on developing an international infrastructure, e.g., by selecting devices, connection requirements and necessary engineering services. GLIF participants are National Research and Education Networks as well as other institutions working with lambda services. The domestic academic association CESNET, who hosts the meeting in Prague, is a member of the GLIF.

The association has dealt with lambda network issues for a long time. Among other things, it has developed the CESNET Lambda service package, based on transmission of optical signal via fully transparent wave multiplex channels between endpoints (E2E). The service is provided on both a national and international level, and is independent of connection providers or types of devices used. Connection between sites and establishment of a dedicated circuit therefore only depends on availability of lambda channels in the links. Their bitrates may be 10 Gbps and more.

The CESNET Association was founded by Czech universities and the Academy of Sciences of the Czech Republic in 1996. It is engaged in research and development in information and communication technologies and builds and develops the CESNET national e-infrastructure for research and education. With its research activities and accomplishments, CESNET represents the Czech Republic in international projects, most notably the pan-European GÉANT network building project and grid projects (, and participates actively in their implementation.
