Design and Analysis of a TRILL - OpenFlow Bridge

Cloud computing is expected to keep growing and therefore more and more data centers are being built. In parallel of this increasing amount of data centers, there are also more cloud providers. On one side, this heterogeneity in the cloud market allows a user to choose and change its cloud provider. On the other side, thanks to this growing number of cloud providers, it is now possible to have small cloud providers forming a cloud federation. This way, they can mutualize their resources in order to accommodate their clients and compete with bigger cloud providers. However, solutions are needed to interconnect data centers. Those solutions must allow a cloud provider to interconnect its data centers to other cloud providers' one. This interconnection must be achieved even if the data centers do not use the same technology. This is the problem we focus on in this paper and we propose a solution to interconnect a TRILL data center with an OpenFlow one. We design and implement this solution in order to analyze its impact on both throughput and latency. Concerning the latency, we found that our solution increases it by 3% compared to the OpenFlow solution. Throughput-wise, we have an 8% lower throughput than TRILL.
