What is not and is UCLP? Table of Contents

> What is not UCLP?

> What is UCLP?– Version 1– Version 2

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 UCLP?CA*net 4; a layer 1 network

1st & 2nd wavelengths – 10 Gbps

3rd wavelength – 10 Gbps

4rd and 5th wavelengths are coming soon…

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 create 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 achieved via the lease process.

- Lease period has a start 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 lease period, the users loose the ownership ofthe LightPaths.LightPaths come back the pool .

> Now let’s imagine that the users would like to manage a subset

of CA*net as part of their network including add/drop, routing, partition,

concatenate, etc.

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).

> 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.
