to create the virtual circuits or Label Switched Paths (LSP's). Quality of Service (QoS) is used to

provide bandwidth guarantees.

GEANT2 AutoBAHN:

AutoBAHN (Automated Bandwidth Allocation across Heterogeneous Networks) 0 is a service

architecture that allows authorized end-users to directly access network resources from their

workstation, wherever it is located in Europe. This is achieved by setting up on-demand dedicated

circuits spanning multiple countries, and multiple networks, administered by different entities and

using different technologies.

AutoBAHN has as its primary objective to provide automatic bandwidth management for

heterogeneous European NRENs' infrastructures. The network technologies initially targeted by

AutoBAHN are Ethernet and SDH, which are the most common among potential system users.

The AutoBAHN system is based on the Inter-Domain Manager (IDM), which is responsible for

inter-domain aspects of circuit reservation. This includes inter-domain communication, resource

negotiation among domains, resource scheduling, and topology advertisements

GLIF:

GLIF, the Global Lambda Integrated Facility 0, is an international virtual organization that

promotes the paradigm of lambda networking to support demanding scientific applications. It is a

collaborative initiative of research networks across the world, as well as institutions and consortia

working with lambdas.

The Control Plane and Grid Integration Middleware Working Group 0 agree on the interfaces and

protocols for communication between the GLIF resources. The group determines which control

information needs to be exchanged, and investigates automation of the controlling mechanisms.

The new model foresees automatic delivery and on-demand provisioning over optimized network

paths, made possible by optical control plane technologies.
