13. JRA1: Future Network - Objectives
Bring innovation to the infrastructure by investigating emerging technologies that enhance the network infrastructure and the portfolio of services:
Carrier Class Transport technologies PBT Provider Backbone Transport & T-MPLS Transport Multiprotocol Packet Label Switching
Photonic equipment based on the state of the art Photonic Switching
Study new architectural paradigms applicable to backbone networks with the objective of optimising the use of resources deployed:
Federated Network Architectures
Current & future use of Virtualisation Services
The results of JRA1 will feed into:
SA1 Network Planning & Procurement
Reference for GN3 community when designing NGN and services
Influence the technical roadmaps of vendors with the GÉANT & NREN requirements.

14. JRA1 Task1 Carrier Class Transport Network Technologies
Study connection-oriented technologies: Provider Backbone Transport (PBT) and Transport Multiprotocol Packet Label Switching (T-MPLS/MPLS-TP)
to support: point-to-point, point-to-multipoint, and VPN services.
This work will research the exploitation of the hybrid infrastructure by emerging connection-oriented transport technologies such as Carrier Class PBT and T-MPLS in order to support point-to-point, point-to-multipoint and VPN services.
The fundamental functionalities that will be assessed in the study and testing include:
Scalability;
Traffic shaping and policing capabilities ;
Support for multicast;
OAM&P Operations, Administration, Monitoring & Provisioning functionalities like protection switching and restoration, efficient fault localization and multi-operator service offering;
Layer 2 QoS;
Layer 2 routing and their monitoring and management capabilities.
The expected results of the work are the:
Production of reference papers for GEANT and NREN’s future transport network technologies;
Inclusion into equipment vendors technical roadmaps of the requirements of GEANT and NRENs resulting from the testing and evaluation.
Scalability
Shaping and policing
