Current developments in optical components' technologies enable wavelengths to be very narrowly spaced, transforming the optical fiber into a multi-terabit capacity medium. A new generation of " all-Optical " Cross-Connects started to appear in the market leading to a number of advantages such as increased switching capacity, decreased overall network(More)
Grid applications require computing, storage and network resources offered from different Resource Centers (RCs). For the exchange of resources and the data transfers between two RCs an end-to-end path should be created. To provide QoS assurances to this end-to-end path, the complete path should be reserved and configured to offer that particular service(More)
Handling multiple sets of trouble tickets (TTs) originating from different participants in today's GRID interconnected network environments poses a series of challenges for the involved institutions. Each of the participants follows different procedures for handling trouble incidents in its domain, according to the local technical and linguistic profile.(More)
This deliverable presents the various approaches and technological options in terms of equipment for lighting dark fibre and creating lambdas, which are suitable for research and education communities in SEE countries in the short-medium term.
We describe the IPv6 transition mechanisms available to the National Research and Education Networks (NRENs) who are part of the 6NET project. The mechanisms need to operate to complement those that provide an IPv6 service to the end users in the universities. We review the mechanisms, state the current usage of those mechanisms, and describe some of the(More)

We describe the IPv6 transition mechanisms available to the National Research and Education Networks (NRENs) who are part of the 6NET project. The mechanisms need to operate to complement those that may apply in the core IPv6 network, and most importantly to provide an IPv6 service to the end users in the universities. We review the mechanisms, state the(More)
