Project Progress

UEssex working on integration of ADVA optical components

10 June 2011

As part of the OFELIA experimental facility, the island of the University of Essex (http://hpn.essex.ac.uk) will allow researchers and experimenters to conduct innovative and novel investigations on slices of OpenFlow enabled Ethernet switched. In the first phase of the OFELIA project, the island of university of Essex, includes four OpenFlow enabled Ethernet switches (NEC IP8800/S3640-24T2XW), three carrier grade Ethernet switches (Extreme BlackDiamond 12804) along with one Calient Diamond Wave fibre switch. An experimental mesh network topology can be created using the NEC switches. A 10 Gigabit Ethernet (GE) link from JANET (UK’s National Research and Educational Research Network), which terminates on Carrier Grade Extreme Black Diamond Switch provides the Internet connectivity of the UEssex island.

In the next step of the OFELIA project, three optical Reconfigurable Add/Drop Multiplexers (ROADMs) (ADVA FSP 3000) will be integrated to the UEssex island. In a joint collaborative effort, University of Essex (http://hpn.essex.ac.uk) and ADVA Optical Networking (http://www.advaoptical.com) will develop the required software to integrate these optical equipments into the OFELIA federated islands. The initial approach is to provide the OpenFlow functionalities on top of the GMPLS-based control plane of the optical equipments. The HPN group has recently performed an experiment to integrate its virtualized Calient fiber switches controlled by an OpenSource GMPLS control plane into the OpenFlow networking environment, by developing an extended OpenFlow controller. The initial approach will represent the optical equipments to the experimenters as an OpenFlow enabled switch and the add/drop ports of the ROADMs will play the role of the OpenFlow switch ports. The internal connectivity in the circuit switched domain (optical domain) will be controlled by an extended OpenFlow controller and GMPLS control plane following an overlay approach.

 

OFELIA development team strengthens continuous development of expedient control framework

10 June 2011

Led by i2cat (www.i2cat.net), OFELIA’s development team (WP5) is working hard to release the new version of the control framework software based on the expedient framework developed by Stanford University for automated management of the OFELIA facility. After the first release (Alpha) and Release Candidate 1 (RC1), all OFELIA partners are currently extensively testing the new Release Candidate 2, which will be finally merged in the first week of June. This new version will make new features available including better management of virtual machines in XEN based server environments, improved address management and allocation, and enhancements to the graphical user interface using AJAX technology for real-time resource status monitoring. This RC2 will also fix numerous bugs that have been identified in the last weeks, moving OFELIA’s control framework towards a stable and mature experimentation environment.

 

OFELIA Facility Soon Becoming Operational

10 June 2011

The facility initial set-up phase is coming to its end and users can start experimenting. The first public service offering is planned for July 2011.

The usage of the OFELIA facility will be provided "as is" as a free-of-charge best-effort service. Any user accepting the usage policy is welcome to experiment on the OpenFlow-enabled testbed.

 

 

 

 

 

OFELIA Control Framework Software Released

10 June 2011

The  first version was released in April. The control framework software is based on the expedient framework developed by Stanford University.

Currently, all OFELIA partners are extensively testing the control framework software and working towards the next improved version. This second version, expected to be finalized in June, will fix bugs that have been identified and also make new features available. The new features include better management of virtual machines in XEN based server environments, improved address management and allocation, and enhancements to the graphical user interface using AJAX technology for real-time resource status monitoring.
