Advancing Connectivity Service Provisioning in GMPLS Networks

This project explores the integration of Quality of Service (QoS)-enabled networking for applications like TV broadcasting, Grid computing, and Digital Cinema within GMPLS (Generalized Multi-Protocol Label Switching) networks. Key partners include Scuola Superiore Sant’Anna (Italy), Fondazione Ugo Bordoni (Italy), and KTH Royal Institute of Technology (Sweden). The goal is to establish a service plane architecture that effectively partitions functionalities between application and transport layers, enabling on-demand network services across multiple vendors' equipment. Expected outcomes include experimental validation of service plane architectures and multivendor compatibility for VPN provisioning.

Presentation Transcript

  1. Joint activity within VD-C Advanced Connectivity ServiceProvisioning in GMPLS Networks Participants: • Scuola Superiore Sant’Anna (SSSUP, Italy) • Fondazione Ugo Bordoni (FUB, Italy) • Royal Institute of Technology (KTH, Sweden) Contacts: barbara.martini@cnit.it, fabio.baroncelli@cnit.it lrea@fub.it lena@it.kth.se

  2. Motivation and scope • Connectivity request issued by qualified applications (e.g., TV broadcasting, Grid, Storage, Digital Cinema) need QoS-enabled network services that can be provided by sub-IP transport objects only • Applications cannot access the GMPLS UNI nor it is recommended they do that, existing Service Platform (e.g. IMS) only operate at the IP level • Introduction of service functionalities in metro/core transport network architecture for the provisioning of on-demand network services • Definition of the horizontal and vertical boundary of a network and which functionality of the service platform should be placed where (inside, outside, or partially overlapped)

  4. The service plane

  5. Testbed to be finalized at KTH

  6. Capitalizing competence and resources • Previous collaborations funded by e-photon/ONE and COST270 helped to gain a common background. • SSSUP experience: • Architecture of the Service Plane • Preliminary development of functional blocks • Experimental competence on Juniper network elements • KTH experience: • Experimental competence with various vendors • Availability of the multivendor ACREO testbed • FUB experience: • Experimental competence on Juniper and Cisco network elements • Competence on Traffic Engineering

  7. Expected results • Demonstrate and validate experimentally the architecture of the Service Plane designed by SSSUP • Demonstrate the multivendor operation of the Service Plane for provisioning of VPN Services at L1, L2 and L3 • Gain competence on a large and heterogeneous testbed such as the ACREO testbed • Integrate competence of the three involved partners
