Agile All-Photonic Networks (AAPN)Profs. Gregor v. Bochmann, Trevor Hall, Oliver Yang

This is an NSERC Research Network (5 universities and 5companies) funded over 5 years

Theme-1: Network architectureCoordinator: Gregor v. Bochmann

Objective: Share the large (10Gbps) bandwidth of an

optical wavelength among many flows based on time-sharing and very fast photonic switching (without o-e-oconversion in the switches)

Typical network parameters: Overlaid star architecture

1000 edge nodes connected to one or more photonic coreswitches

Switching speed of 1 micro-second for time sharing

Scalable system architecture by using different number ofwavelengths and concentrators for sharing a core port amongseveral edge nodes

Issues: (a) Many edge nodes and a few core nodes(b) IP/MPLS over an AAPN

AAPN: Research problems

Bandwidth allocation for the flows among the

edge nodes (performed at each core)

Fault recovery in case of link or node failure Routing of Internet traffic (IP and MPLS) over an

AAPN

Integration of fast switching AAPN with ROADMnetworks (slow switching; tens of milliseconds)

and static DWDM networks

User Controlled Lightpaths (UCLP)Prof. Gregor v. Bochmann in collaboration with CRC,

i2Cat (Barcelona) and Inocybe (Montreal)This was a project largely funded by Canarie with theobjective to develop a control platform for network andend-system resources that can be used by the end-userand which can control network devices from differentmanufacturers. It is based on Web Services.

The UCLP-V2 system is now being used by Canarie andother organizations in different countries.

Further research issues are:

Extensions for the support of various switch and

network control protocols, including GMPLS Support of lightpath multicasting

Inter-domain routing

Integration with Grid computing

User-Controlled Lightpath Provisioning Version 2

(UCLPv2)Prof. H.T. Mouftah in collaboration with Prof. O. Cherkaoui (UQAM)

Objective: To provide a software that enables users to create and manage

APN (Articulated Private Network) through interaction with the

advertised resources of CA*net 4 and similar optical networks. Users

interact with the system using a GUI, and web service interfaces.

UQAM-UO UCLP-V2 system is now being used by Canarie and other

organizations in different countries.

Further Research:

- Survivability

- Multicasting

- Multi-domain setting

Limited-Perimeter Vector Matching (LVM)

Fault Localization Protocol

To narrow down the associated time and space

complexities, the protocol restricts the fault

localization area to a small area called limited-perimeter.

Patent Pending.

NSERC I2I for commercialization.

OCE Market Readiness application.

LVM protocol deployment on our ONRL testbed.
