GLIF - the Global Lambda Integrated Facility - is an international collaboration that promotes the paradigm of lambda networking (circuit-oriented networking), primarily in support of demanding scientific applications.  The GLIF participants are research & education networks, research organizations, science communities, and individual researchers.  In GLIF, they get together to explore and develop the technologies for lambda networking, report on recent developments, agree best practices and develop technology standards, and stage large-scale, global experiments to demonstrate the technologies and use-cases.

The work of GLIF is centered on the Annual LambdaGrid Workshop, a global meeting with presentations, demonstrations, and far-reaching discussions on all aspects of lambda networking, and on a number of task forces organized in the GLIF Technical Workgroup (GLIF TECH).  The task forces bring together global experts in aspects of lambda networking, working together to develop implementations of proposed technologies, explore new approaches, and stage focused discussions for the larger GLIF TECH community in the GLIF TECH meetings held at least twice a year.

GLIF is not a network, however, many of the participants are network resource providers, and jointly they offer an impressive range of global connectivity at high-capacity.  Working together in GLIF allow the partners to provide global, high-capacity connections for global data-intensive scientific research efforts and for scientific and technology demonstrations, helping to break new ground in both science and networking.

GLIF TECH Working Group

The goals of the working group are to design and implement the facilities that allow the creation of a global LambdaGrid infrastructure, identify equipment and technologies to be used, understand connection requirements, and the functions and services required.  GLIF TECH supports middleware development for lambda networking. It brings together some of the world's premier networking engineers who are working together to develop next-generation global networking.

Work items include:

  • Define standard terms for GLIF technical resources.
  • Define which services should be provided.
  • Facilitate standardization of key technologies and help implement those standards on the global network footprint.
  • Identify and document the best current practices within GLIF and create operational guidelines
  • Develop global automation of control plane mechanisms.
  • Offer a sounding board for new technologies and their impact on lambda networking
  • Facilitate global testbeds for emerging lambda networking technologies.

The GLIF TECH works through a number of task forces, focusing on specific items in the GLIF TECH work program.  Current task forces inlude the AutoGOLE testbed taskforce, the NSI Implementation taskforce, the GOLE Operators taskforce, and more.

GLIF TECH is co-chaired by Eric Boyd (Internet2) and Lars Fischer (NORDUnet).
