    1 : Optical Networking Services 1 Optical Networking Services Some slides and most of the graphics are taken from other slides Tal Lavian tlavian@eecs.berkeley.edu
    2 : Optical Networking Services 2 Research Direction The research topic that I’m looking after is Applications and Services Infrastructure for Optical Networking What is a service composition and how we build a service? What building blocks are needed and how cooperating and brokering should work in optical infrastructure and among providers? A good starting point can be to look into some applications and pick few (2-3). We can look into the TeraGrid and SAN, and we should see how the dynamic behavior of emerging optical networking technologies could benefit the applications We need to look all the way from the problem, solution, application, architecture, services, and how this is implemented and what services are needed in each layer
