What is UCLP?
• User Controlled LightPaths – a configuration and
provisioning tool built around grid technology using web
services
• User can combine together various links, routers and
switches to produce a wide are network that is under their
control
• Articulated Private Network (APN)
• Uses Service Oriented Architecture (SOA) and so network
can be integrated with other web service applications
• With SOA instruments, devices, sensors and wireless
devices can also be integrated
• All under user control and architecture

• Provides software tools to allow the network administrator
to partition its network elements into multiple resources,
and expose its capabilities through web service interfaces.

• Provides software tools to allow the network administrator
to create logical resources that provide an abstracted view
of the network element resources and how are they linked
to each other.

UCLP: Topology creation/editing
• Provides software tools to allow users (including physical
network admins) to create, reconfigure and delete network
topologies using the logical resources acquired from
different resource providers.
Utility Web
Service A
Utility Web Service A creates
point to point connections
using SONET/SDH resources
(withVCAT, LCAS, GFP)
Utility Web Service B creates
point to point and point to
multipoint connections over
Ethernet resorces (using
VLANs, Q-inQ, …)

Use Case Scenario
• A group of partners of an European project need some
resources of GÉANT2 and two NRENs: NREN A and NREN B.
– Network Providers: GÉANT2, NREN A and NREN B.
– User: Network administrator (or testbed WP leader) of the European
project.

13
Network Provider Functionality
• Create the Physical Network
– Add network elements and physical links
• Delete / Create connections (on a network element per
network element basis)
• Monitor the physical network, see usage statistics.
• Create logical resources (lightpaths and interfaces)
• Use the logical resources himself (directly or through use of
high level applications / utility web services)
• Lease logical resource to other users / Get new logical
resources from other users

Advanced User Functionality
• Create logical resources (lightpaths)
– Can create a lightpath ws out of two adjacent interface ws
• Use the logical resources himself (directly or through use of
high level applications / utility web services)
• Lease logical resource to other users / Get new logical
resources from other users
20
Get one or more Resource List(s)
21
Merge all the Resource Lists
22
APNs are multidomain…
23
Use the APN..
Advanced user creates
connections from the GUI
Advanced user creates an
instance of the “APN Scenarios”
service for a regular user

Current Status
• Supported technologies:
– Untagged Ethernet, SONET with CCAT.
• Supported equipment:
– Cisco ONS 15454, Nortel OME 6500, Nortel HDXc.
• Available utility services:
– “APN Scenarios” service: You can define a set of preconfigured
network topologies, and set them up / tear them down with a
single call.
• Available UCLP releases:
– UCLP Community Edition (coming end of June)
30
Future activities
• Add support for more technologies:
– MANTICORE project: physical and logical routers, users will be able
to create their own customized IP network.
– Add support for SDH, MPLS, tagged Ethernet, Virtual
Concatenation, ROADMs, GMPLS.
• Add more utility web services:
– Currently a Network Reservation System for UCLP is under
development. An adapter will be developed under the
PHOSPHORUS project so that the UCLP Reservation System is
compliant with the PHOSPHORUS project.
• Create a “UCLP Group”, that, together with Inocybe
Technologies Inc. can provide professional UCLP solutions:
support, training, customized services.
