[CAnet - news] Example of Concurrent network deployed across CA*net 4 with UCLP

For more information on this item please visit the CANARIE CA*net 4 Optical
Internet program web site at http://www.canarie.ca/canet4/library/list.html
-------------------------------------------


[Further to my previous posting, the following is a good example of a
concurrent network application using UCLP.  The CA*net 4 network is
different than most other Internet R&E networks in that it was designed from
the very beginning to support multiple concurrent networks (Articulated
Private Networks- APNs). The National Lambda Rail in the USA has a similar
network architecture.  UCLP allows the owner of a given concurrent network
to spawn child concurrent networks and assign these networks to other users
as well as manipulate the link topology and the interconnection of virtual
routers, switches and instruments (hence the expression "articulated"). With
UCLPv2 this is all done through web services and web services workflow using
a simple workflow graphics interface.  Recently CANARIE provided a major
government department - Environment Canada an APN linking the various
Environment Canada computer sites across the country which demonstrates
these capabilities (including creation of multiple child APNs) as further
described in this note from Herve Guy - CANARIE's UCLP project manager. The
following web pointer shows all the various screen shots of the GUI to
complete the creation of these APNs.  -- BSA]

Here are some few words about this Environment Canada’s Articulated Private
Network:

The new concurrent private network, running on CANARIE infrastructures, will
link several of Environment Canada’s national laboratories. The network will
facilitate the development of meteorological models for various applications
that factor in all the conditions found in our vast and multifaceted
country, in addition to hydrology research at our national laboratories.
Environment Canada will also use it to test new networking technologies.

Le nouveau réseau privé roulant sur les infrastructures de CANARIE servira
pour relier plusieurs des laboratoires nationaux d'Environnement Canada. Les
applications incluront le développement de modèles météorologiques pour
diverses applications pour y inclure toutes les conditions que notre grand
pays diversifié peut offrir ainsi que des recherches en hydrologie auprès de
nos laboratoires nationaux. Environnement Canada en profitera aussi pour
mettre à l'essai de nouvelles technologies de réseautique.

In order to achieve it, 2 UCLPv2 servers, created CIIU (Communications
Research Centre in Ottawa, Canada; the i2CAT Foundation in Barcelona, Spain;
Inocybe Technologies Inc. in Montreal, Canada; and the University of Ottawa
in Ottawa, Canada) have been used (http://www.uclp.ca/).

The first UCLPv2 server is run by CANARIE for managing CAnet 4’s resources.
CANARIE staff created the physical representation of CAnet 4 via the
Physical Network Editor (ref. to canet4-physical-network.jpg) in UCLPv2, as
well as its Logical representation, i.e. LightPath and Interface Web
Services, via the Logical Network Editor (ref. to
Canet4-logical-network.jpg). Once everything was in place, CANARIE staff
finally created the Resource List for Environment Canada via the Resource
List Editor. This Resource List is now hosting all the CAnet 4’s resources
required for deploying Environment Canada’s new articulated private network.

The second UCLPv2 server is run by Environment Canada’s for managing new
articulated private network, running on CANARIE infrastructures. The APN
Administrator at Environment Canada, has imported the above-mentioned
Resource List for Environment Canada (ref. to EC-Resource-List.jpg). Via the
Resource List Editor, the APN Administrator could display and manipulate
resources that have been given to them from physical network providers, i.e.
CANARIE. In fact, the functionality of the Resource List editor is the same
as that of the logical editor except that there is no accompanying physical
network. It is meant for APN Administrator to use to display and manipulate
resources that have been given to them from physical network providers, i.e.
CANARIE. Resources in this view can be selected to create new Resource
Lists, APNs or E2E Connections.

Here the APN Administrator has decided to create/deploy and execute 5 APNs
(please refer to APN-Sas-Tor.jpg, APN-Sas-Mon.jpg, APN-Vic-Mon.jpg,
APN-Tor-Mon.jpg and APN-Mon-Hal.jpg). This is via the APN Editor, that the
APN Administrator (or End User) could display, deploy/undeploy and
execute/undo APNs. Before deploying an APN, the APN Administrator (or End
Users) must choose the topology of this APN by selecting resources on the
above-mentioned Environment Canada’s Resource List that will form the
different E2E connections in the APN. Once the 5 EC’s APNs has been
deployed, EC’s APN Administrator has simply executed them, which has put
cross connections in place on the CAnet 4’s Network elements…
