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

TL-1 Interface via Telent• act-user::calient:::*******;

• rtrv-conn:::::all;

• Ent-conn::0.11a.7,,50.50.50.50,,0.11b.4:::2way,calient,test_tl1:srvclass=UPR,bandwidth=10000-GigE,lspencode=ETHERNET,lsppayload=ETHERNET;

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(<SinglePath>)

• Multicast connection: Multicast(source, <destination1,...,destination2>, 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
