9. TERENA Networking Conference 2008, Bruges (BE), May 19 th – 22 nd, 2008 WHY G 2 MPLS ?  uniform interface for the Grid-user to trigger Grid & network resource actions  single-step provisioning of Grid and network resources (w.r.t. the dual approach Grid brokers + NRPS-es)  adoption of well-established procedures for traffic engineering, resiliency and crankback  possible integration of Grids in operational/commercial networks, by overcoming the limitation of Grids operating on dedicated, stand-alone network infrastructures G2G2 G2G2 G2G2 G2G2 G.I-NNI G.E-NNI G.O-UNI G 2 MPLS NRPS Vsite A Vsite B Vsite C G.O-UNI Grid nodes can be modelled as network nodes with node-level grid resources to be advertised and configured (this is a native task for GMPLS CP)

10. TERENA Networking Conference 2008, Bruges (BE), May 19 th – 22 nd, 2008 WHAT IS G 2 MPLS ?  G2MPLS is … a Network Control Plane architecture that implements the concept of Grid Network Services –GNS is a service that allows the provisioning of network and Grid resources in a single-step, through a set of seamlessly integrated procedures. expected to expose interfaces specific for Grid services made of a set of extensions to the standard GMPLS –provide enhanced network and Grid services for “power” users / apps (the Grids) basically, a superset of GMPLS

11. TERENA Networking Conference 2008, Bruges (BE), May 19 th – 22 nd, 2008 G 2 MPLS CONTROL PLANE MODELS  Two models for the layering between Grid and Network resources G 2 MPLS overlay model different scope with respect to the IETF GMPLS Overlay & Peer G 2 MPLS integrated model

25. TERENA Networking Conference 2008, Bruges (BE), May 19 th – 22 nd, 2008 A PROPOSAL FOR G (2) MPLS DEPLOYMENT IN THE NRENS 24

26. TERENA Networking Conference 2008, Bruges (BE), May 19 th – 22 nd, 2008 DEPLOYMENT OF G 2 MPLS IN NRENS  Some add-ons to the required GMPLS feature list Advance reservations Co-existence with adjacent NRPS Clear resource partitioning and virtualization Path computation for lambda networks (optical impairments) + management of advance reservation  Grid+network specific desiderata Integration of Grids with NRENs infrastructures (a.k.a. add a CP to Grids) –No more a “ships-in-the-night” style but reciprocal awareness and seamless one- step configuration Identification of the reference points and CP models Integration and escalation of recovery procedures Integration with existing AAA AuthZ mechanisms for Grids Integration with existing NMS

27. TERENA Networking Conference 2008, Bruges (BE), May 19 th – 22 nd, 2008 COEXISTENCE OF GMPLS AND G 2 MPLS [1]  Mainly an inter-domain problem G 2 MPLS nodes dispersed in GMPLS domains act as std-GMPLS nodes (routing, signalling) GMPLS nodes merged in G 2 MPLS domains cannot act as G 2 MPLS nodes  The most convincing future scenario for intra-domain coexistence seems to be a multi-region domain Phosphorus G 2 MPLS used to provide CP capabilities to equipments currently lacking in it (e.g. carrier Ethernet switches or similar) Off-the-shelf GMPLS used to control SDH or WDM technologies

28. TERENA Networking Conference 2008, Bruges (BE), May 19 th – 22 nd, 2008 COEXISTENCE OF GMPLS AND G 2 MPLS [2]  … but in the inter-domain context G 2 MPLS domains handle both Grid and network resources ASON/GMPLS domains control only network resources  This implies a reduction of the information set carried out through the G.E-NNI, both for routing purposes and, above all, for signalling
