14. TERENA Networking Conference 2009, Malaga, Spain  The Control Plane implemented by a set of G 2 MPLS node controlers Each of them operates exclusively on a Transport Network element (real or derived from partitioning) Each controller is interfaced to the Transport Network equipment (Southbound Interface) through TL1 (ADVA, CALIENT), CLI (Allied Telesis) and SNMP (Foundry XMR) Node controllers run on i386 32-bit platform with Gentoo Linux distribution  Signaling Control Network (SCN) To transport signaling messages between the CP components Each G 2 MPLS exposes at least an interface on the Signaling Communication Network (SCN) over which the G 2 MPLS protocol messages flow SCN is IP-based with addresses from the private scope. IP tunnelling is used for out of band connectivity between controllers. G 2 MPLS test-bed – Control Plane [1]

38. TERENA Networking Conference 2009, Malaga, Spain Summary  Currently, the Open Source G 2 MPLS protocol stack supports the representatives from three main technology areas: LSC, FSC and Ethernet The stack is extendable: quick and simple development of the extensions in support of different vendors and equipment Extensions for low-cost Ethernet switches has just been developed and tested  PHOSPHORUS G 2 MPLS is backward compatible with ASON/GMPLS Provides „legacy” ASON/GMPLS transport services and procedures This compliance fosters the possible integration of Grids in operational and/or commercial networks  G 2 MPLS allows to run any kind of applications, even not bridged by Grid Middleware. It is possible to connect the application directly to the network through G.OUNI, bypassing existing gateways developed for UNICORE Corba interfaces allow easy plug&play of external applications in the G 2 MPLS framework
