THE REACTION TEAM AT OFC 2014 In March of this year, the team of researchers from the REACTION project presented their work at the 2014 OFC Conference in San Francisco. The REACTION partners are a mix of public and private: the Italian research center CNIT, the Universitat Politècnica de Catalunya and the Spanish Telefónica. They share a broader collaboration in the EU IDEALIST project, which brings together major european telecoms and public research labs to study elastic optical network technologies. Some key issues emerging from this work are taken up by REACTION, in particular a new transponder technology that enables so-called “sliceability” in optical networks.


At OFC the team presented not only their current work on sliceability, but also a special post-deadline paper describing an experiment on network re-optimization based on the innovative ABNO architecture. Both presentations were extremely well received, which bodes well for the industrial take-up of their solutions: “For UPC and CNIT this is an important step in an ongoing research process,” says Filippo Cugini, coordinator of the project “but for Telefonica, the aim is to standardise these solutions and propose a new standard to IETF, which would require vendors to provide support for it in their products.”



Network coding (NC) is a technology that promises to more than double network capacities while increasing reliability and security. Although NC was originally designed for transport networks, an implementation at this layer is not yet available. The MINERVA project is working to fill this gap and implement robust network coding methods in the GÉANT OpenFlow facility: “We are seeking methods that are bandwidth-efficient, easy to implement, and scalable; easy to maintain protection methods which could be implemented in practice;” says project coordinator Peter Babarczi, “we have been working on this topic from a theoretical point of

view for years, but this is the first time we can implement it in a real, large scale network.” The MINERVA partners, MTA-BME Future Internet research group and the i2cat Foundation, are both well known for their work in this area, with numerous IEEE publications and several prestigious awards to their name. They already have a successful NC implementation that was demonstrated at the latest Sigcomm. MINERVA is implementing a proof-of-concept for the practical applicability of network coding in SDNs in the key areas of video streaming and distributed storage.
