1st ”Establishing Lightpaths” 1st ”Establishing Lightpaths”

› E-science applications can generate network flows measured in Gb/s, enduring hours, days or even weeks, often between a , g , y , well-defined set of nodes, and with tight constraints on quality

• f service

› The needs of such applications are best met by traffic pp y engineered point-to-point circuits, rather than best effort routed networks like the public Internet. › End-to-end lightpaths (i.e., Gigabit Ethernet circuits or even g p ( , g lambdas) are becoming very important in the service portfolios

Outcome of the discussions

i t t interest areas

1. Unified/ Standardised network architectures for end-to-end provisioning p g 2. Simplicity of the provisioning processes and software tools

› Faster provisioning has still highest priority over dynamic provisioning nowadays › Fast and automated restoration of the broken connections

3. Availability of resources, especially in the last mile

› Fibre availability, Spectrum efficiency › Access technology (PONs, Ethernet-based platforms), Cost efficiency

4. Reliability of point-to-point circuits

3rd ”Applications and Services”

• There is an issue with the lack of applications requiring e2e

connections.

• We need to identify the key applications and promote e2e

services for end-users.

• We should include the application developers/designers.

pp p g

• We need to deal with real application-to-application services

and not just edge-to-edge connection services.

• We need to understand the campus policies.
• We need attractive business models and we need to

understand and explain the cost implications of e2e services for
