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

• 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

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, netconnect
Reliable control plane network
L1/2/3 LSP hierachy
