Resource Brokering: Your Ticket Into NetherLight Paola Grosso Jeroen van der Ham Cees de Laat UvA - AIR group
Optical exchanges: the entry point for lambda networking
Lambda networking Lambda networking allows applications to dynamically use dedicated wavelengths (lambdas) over a shared fiber infrastructure. GLIF- Global Lambda Integrated Facility - international virtual organization that promotes the paradigm of lambda networking
An optical exchange: NetherLight A SONET/SDH cross connect and Gigabit Ethernet switching facility in Amsterdam. One of the entry points into the GLIF.
UvA/SARA LightHouse A joint network research lab of the University of Amsterdam and SARA. Connects end resources to NetherLight.
Semantic web a universal medium for the exchange of data where data can be shared and processed by automated tools as well as by people The Resource Description Framework (RDF) uses XML as an interchange syntax. Data is described by triplets: ObjectSubject Predicate
NDL - Network Description Language A way to describe network resources using RDF. Parser can use the data to: -generate network maps -provide information to schedulers Vangogh3 ComputingElement
Key issue #2: How to book resources on such networks?
Resource Scheduling Clients will want to: -Know about available resources, and connectionts among them; -Reserve the resources, and setup the connection for the duration of their experiments. Providers of services want to: -Schedule resources in most efficient way -Interact with other providers to provide multi-domain end to end paths.
Web services Web services interfaces provide the API for the reservation framework:
