NCHC & KISTI’s UCLP demo at APAN Taipei 2005
> Hervé Guy’s BIO– I am working with CANARIE INC, at Ottawa, in
CANADA since 1995.– I have joined the Advanced Research Network
group, which are responsible of the deployment of CA*net Network in Canada, in 1998.
– I was leading the “STATS” initiative on CA*net 4 between 1998 and 2002.
– I am now managing the development of the UCLP (User Control LightPath) Software since 2003.

CANARIE's Directed Research Program History of UCLPv1 Software
> Co-funded by Cisco Canada and CANARIE (http://www.canarie.ca/funding/research/projects.html)
> Held in 2003.> 10 proposals submitted> 3 proposals selected
– University of Waterloo (http://bbcr.uwaterloo.ca/~canarie/index.htm)
– University of Ottawa - Communications Research Centre (CRC) (http://phi.badlab.crc.ca/uclp/)

UCLPv1 deployment on CA*net 4 (http://www.canarie.ca/canet4/uclp/uclponc4.html)
> For ease of management of lightpath on CA*net 4, a user must comply with CANARIE's Lightpath Allocation Policy and must fill out CANARIE's Lightpath Request Form.
> Only registered source IP addresses will be permitted to connect to the lab. Requests are to be sent to eng@canarie.ca.

What is not UCLP? Confusion about UCLP
> UCLP is often wrongly associated with other dynamic optical switching protocols.
> UCLP has nothing to do with optical control planes or providing bandwidth on demand.
> Primary purpose is NOT– a dynamic switched optical networks– a reservation and leasing of wavelength resources– an end-to-end optical VPNs– an inter-domain connection of LightPaths
What is UCLP? UCLP Objectives
> UCLP is an IP network provisioning and configuration tool– it allows the creation of application or discipline specific IP
networks that can be built from optical paths obtained from a mix of heterogeneous network resources across different management domains
– Similar in concept to X-bone VPN overlay network, except at layer 1
> User controlled traffic engineering– Active replacement for Sockeye and Route Science– Alternative to MPLS
What is UCLPv1? It talks about users empower the network!
1st & 2nd wavelengths – 10 Gbps3rd wavelength – 10 Gbps
4rd and 5th wavelengths are coming soon…
CA*net 4;a layer 1 network
What is UCLPv1?What is a LightPath?
> According to “User controlled Lightpath Definition Document (http://www.canarie.ca/canet4/library/c4design/user_controlled_definition.ppt)”, created by Bill St. Arnaud in December 2002:
– Any uni- or bi-directional point to point connection with effective guaranteed bandwidth
> Examples of LightPaths on CA*net: STS channels on a SONET or VC4 channels on SDH circuits
LightPath has Bandwidth, start and
end points
ons-tor01; slot 5; port 1; channel 72
ons-ott01; slot 12; port 1; channel 72
STS24c (OC24)
What is UCLPv1?CA*net 4 is a pool of LightPaths
- Which have been created by UCLP admin (e.g. c4noc).
What is UCLPv1?What are the Users?
?You!
That simply wantsto best achieve
your job!
What is UCLPv1? Users takecontrol of LightPaths on CA*net4
- Ownership of LightPaths is the starting point…
- Ownership period has a start now and end dates.
What is UCLPv1? Users creates an e2e connections on CA*net4
concatenate LPs
access LPs
access LPs
- Users access the LightPaths and run their applications during the requested period.
What is UCLPv1? It talks about users empower the network!
> During the period where a user owns the LightPaths, it could– Partition LightPaths;– Concatenate LightPaths;– Advertise unused LightPaths (i.e. make them
available for another users).– Create/delete the e2e connections (access
LightPaths).
What is UCLPv1? Users deletes the e2e connections on CA*net4
At the end of the ownership period, the users loose the ownership ofthe LightPaths. LightPaths come back the pool .

User Controlled LightPaths version 2;UCLPv2
What is UCLPv2?Purpose
> April 2005 CANARIE issued a call for proposals for UCLPv2, with the objective– to adapt the development of the UCLP software developed
under the Directed Research program in 2003-2004 and make it robust and user friendly for wider scale deployment by providing a graphical user interface (GUI) and providing web service workflow capability.
> The project proposals were due at the end of May 2005.
> Total budget for this RFP is $1.4 million.> Now, 4 proposals has been selected.> All projects will have to be completed by March 30,
2006.

Here is the result (i.e. the logical view) on NRC’s need!
What is UCLPv2?From LightPaths to APNs…
> UVLPv2 is an extension of UCLPv1’s concepts of LightPaths and Users.
> In UCLPv2, the LightPaths and Network Interface (e.g. the GigE ports) become some web services (WS) resources.
> The APN resource list is a pointer to a set of the above-defined WS,
> Finally, an APN (Articulated Private Network) is essentially a workflow script created by the Network Administrator (e.g. CANARIE) that points to a collection of Network LightPaths and Interfaces (e.g. the APN resource list), destined to the APN administrators (e.g. NRC).
What is UCLPv2?From LightPaths to APNs…
> The APN Administrators can download and run the APN workflow script and create functioning APN (e.g. NRC’s CA*net 4 APN).
> An APN could be merge to other APNs for forming a new APN (e.g. NRC’s CA*net 4 APN + NRC’s private APN + SURFnet’s APN).
> The APN could be re-advertise all or some of the APN resource list to other users.
> Finally, the normal users (e.g. NRC’s users) can take control of the APNs resources and establish their own e2e connections.
What is UCLPv2?UCLPv2 in a nutshell!
> UCLPv2– Graphical interface to allow users to create
Articulated Private Networks (APNs)– All lightpaths represented as web services
that are consumed by user by linking through portal on workflow engine
> BPEL or Keppler to link APNs together to form end to end LightPaths and to link instruments.
