Outline Enlightened overview GMPLS networking Extended network service provisioning Based on GMPLS –Enlightened testbed –Calient PXC –Enlightened software architecture

Motivations The need for dynamic high-capacity end-to-end circuits –Ubiquitous and efficient utilization of the distributed scientific facilities –Global collaborations enabled by the Internet, using very large data collections, terascale computing resources and high performance visualizations to maximize the scientific discovery The need for the integrated services to optimally allocate and control compute, storage, instrument, and networking resources –Multi-granularity –Easy and fast access –On-demand provisioning –In advance reservation –Monitoring (feedback) based adaptive provisioning

Key components

GMPLS Introduction Separate data plane and control plane –Data plane network: IP, ATM (MPLS), Ethernet, SONET, Lambda –Control plane network: Internet, private network Control plane protocols –TE: Interface switching capability, link encoding, protection –LMP: discovery and fault management –OSPF-TE: Contraint-based routing –RSVP-TE: signaling explicit routing

Enlightened Testbed Control plane network –IP network –Static public IPv4 address (Using IPSec?) –Using NLR L2 networking service? Data plane network: 4 Calient PXC –NLR: 2x10GE Cisco lambdas, 1 NLR FrameNet circuit –Traffic grooming: via Cisco 6509 –Internetworking with Ethernet switch –E-NNI

Calient DiamondWave PXC Hardware –Modular design –All-optical 3D MEM: bit-rate and protocol independent –Fully redundant and carrier-class reliability –Small footprint, low power… GMPLS enabled networking (So it is not an AFM) –Complete IETF GMPLS conformity –Numbered and unnumbered TE links –Early configuration of MEMs w/ suggested label –Bidirectional LSP setup –E-NNI Intelligent provisioning/control/management tools –GUI –TL-1 –CLI –XML interface –Element management system

XML Interface /common/node.xml /common/event.xml /common/faultMgmt.xml /common/ospf.xml /common/nwconns.xml /common/nwservices.xml /common/loss.xml

Extended Network Provisioning Service (ENPS) A single path: SinglePath(source, destination(s), bandwidth, QoS_Attributes, Time_Attributes) –Unicast –Anycast A number of paths allocated at the same time frame: GroupPath( ) Multicast connection: Multicast(source,, QoS_Attributes, Time_Attributes)

Network Resource Manager (NRM) Without GMPLS –TL-1 interface to every network element along a path With GMPLS –Source routing –In advance reservation TE link state timetable Pre-calculated path database (periodically or triggered update) ERO XML interface provides network monitoring and state feedback

Conclusion & Next step Calient enables dynamic large-area L1/2 network service with GMPLS support Real LSP hierarchy Waiting for more powerful software tools Stability/reliability validation More measurements: cross-connect, net- connect Reliable control plane network L1/2/3 LSP hierachy
