New OFELIA Island Deployed at Brazil

4 October 2013

The OFELIA Island in Brazil is now deployed. Located at Federal University of Uberlândia (UFU), it is based on L2/L3 switches (DATACOM), NETFPGA switches and also the EDOBRA Switches, a software based switch built on top of OpenWrt that offers an abstract control of wired and wireless access links by using OpenFlow protocol and the MIH (Media Independent Handover) defined by the IEEE 802.21 specification and implemented by ODTONE. 

The island deployment was conducted under the EDOBRA (Extending and Deploying OFELIA in Brazil) work package. Currently, the island is running work package experiments that focus on new network architectures that consider aspects such as multicast and mobility in the presence of heterogeneous networks. The Island will become publicly available afterwards.

CNIT-Pisa Island is Ready

4 October 2013

After being federated to the OFELIA infrastructure in March, the final layout of the CNIT-Pisa island has been operational since August 2013. The island is based on OF 1.0 switches (up to 14) based on NetFPGA and Open vSwitch with focus on virtualization-aware traffic engineering in Cloud Data Centers. The switches are interconnected according to a fat-tree topology for reproducing a typical SDN-based Data Center network topology. Accordingly, the island also includes a number of hosts connected to the switches that are controlled by a XEN Cloud Platform for hosting Virtual Machines.

As result of the work, an OpenFlow-based Virtualization-aware Networking (OFVN) platform has been deployed that also consider traffic requirements of VMs for placing them across servers while guaranteeing adequate traffic performance. Specifically, the OFVN platform enables the following capabilities that are being widely experimented under OFELIA:

  • optimization of the VM placement across servers taking into account network resource status (e.g., network link loads) while interacting with Cloud Platforms XEN;
  • enforcement of per-flow routing/switching rules during VM provisioning for optimizing the overall link utilization and avoiding congestions;
  • dynamic reconfiguration of the paths followed by VM traffic flows based on changing cloud resource requirements (e.g., due to VM migrations).

 Finally, the CNIT-Pisa island allows OFELIA experimenters to benefit from Data Center network topologies and carry out experiments in the field of cloud computing and Data Center environments.

OFELIA Extension Sync

10 September 2013

On the 29th and 30th of August, 2013, OFELIA carried out the OFELIA Extension Sync. During the project's lifetime OFELIA has created a substantial amount of software. This includes aggregate managers which manage resources like virtual machines and FlowSpaces, a graphical user interface which enables users to setup their experiments, and a number of libraries and frameworks for general use. All this software together makes up the OFELIA Control Framework (OCF).

OFELIA's software turned out to be useful - not only for the project itself, but other European projects decided to base their facilities and developments on the OCF. These projects are already using or planning to use the results of OFELIA. Most of the projects are also planning to build upon and extend the software. In order to synchronize the development efforts and to create synergies, the project invited them to the OFELIA Extension Sync at the premises of EICT, Berlin.

Several project representatives followed the invitation and the technical meeting started on the morning of the 29th. The first day consisted of technical talks and discussions on how the current OCF works and which decisions have been made along the development path. The invited project representatives from FIBRE, GEANT, FELIX, ALIEN and Fed4FIRE presented their current status and plans regarding the software deployment and extension. Additionally, a member from the GPO (GENI Project Office) gave a talk on their facility and what concepts and software they are currently using. The first day concluded in a Berlin beer garden with discussions on technical aspects.

The second day began with a short talk on general purpose frameworks which stem from OFELIA's development. It continued with introductions on the authentication and authorization concepts used in OFELIA. Then the discussions about the OFELIA development roadmap recommenced. A major outcome was the establishment of a task force called "OFELIA Foundation Task-Force". This group focuses on four aspects to sustain and coordinate OFELIA's software development:

  • Academic relations
  • Industrial relations
  • Software development
  • Network connectivity

The OFELIA Extension Sync proved to be successful. The participants learned about the different projects, ongoing developments and upcoming implementations. This allowed them to find contacts specifically for their project needs. Additionally, the next steps for the developments in OFELIA were defined and layed out in a implementation roadmap.

Updates: EDOBRA (Extending and Deploying OFELIA in Brazil)

17 June 2013

The OFELIA Island in Brazil, located at Federal University of Uberlândia (UFU) is being deployed and by the end of June it is expected to complete the federation with OFELIA at Europe. The Island is based on L2/L3 switches (DATACOM) and also NetFPGA based switches with focus on new network architectures that consider aspects such as multicast and mobility in the presence of heterogeneous networks.

As the host of this OFELIA Island, UFU recently became an associated partner of FP7 FIBRE project (www.fibre-ict.eu), thus strengthening OFELIA international co-operation.

As a result of the work, a carrier-grade service level execution environment that extends SDN based services and puts together OpenFlow protocol and the Media Independent Handover protocol (IEEE 802.21) is being deployed and will be publicly available. Moreover, a clean slate network architecture, called Entity Title Architecture (ETARch), that applies new naming and addressing scheme based on the title and offers an integrated support to multicast and mobility within the Workspace is being deployed and will be experimented at scale under OFELIA.

Recently a paper, called “Enabling Network Mobility by Using IEEE 802.21 Integrated with the Entity Title Architecture” was presented at the XXXI Brazilian Symposium on Computer Networks and Distributed Systems (SBRC). This paper presents a partial view about the work that is being conducted under EDOBRA.

OFELIA Control Framework available under BSD license

6 December 2012

The OFELIA Control Framework (OCF) is a set of software tools for testbed management. It controls the experimentation life cycle; including reservation, instantiation, configuration, monitoring.

The control framework hides the complexities involved in single and federated island setups, still providing enough information so that experimenters can program their environment using heterogenous, scalable resources. It enables allocating resources and running experiments in the whole OFELIA facility.

The OCF is available under BSD license and is being actively developed and used as a production control framework by the OFELIA FP7 project testbed.
