ECOC 2011 OFELIA Workshop attracted more than 30 participants

More than 30 people participated in a lively discussion at the workshop. It turned out that there was indeed a common problem for most of the proposed ideas: a Hardware Abstraction Layer (HAL) for optical and more general for any OpenFlow switches appears necessary for the use of anything more specialized than a plain Ethernet switch. As an example, reconfigurable optical add/drop multiplexers (ROADMs) come in different flavors and switching capabilities (some all are freely configurable in the wavelength to be dropped, others not, some are directional, others not, and so on. In addition the nature of the interfaces is to be described, Meral Shirazipour suggested a GMPLS-like encoding of the interface types, arguing for an easier integration of OpenFlow-capable optical switches into existing GMPLS control planes. Other speakers argued for a more generic and less “legacy” description models.

Three talks on OpenFlow applications like greedy routing schemes and federation languages and resources complemented the workshop with topics going beyond the optical <-> OpenFlow integration. We would like to thank all speakers again for their highly interesting presentations and the opinionated discussion.

The list of speakers and the presentations are available via the OFELIA website.
