Description The high-level objective of the research was to incorporate elements of theory and practice so as to further research on interconnection networks. These objectives have been met and we have contributed significant new results on server-centric data centre networks all of them supported by research papers published in top journals and/or conferences. Our primary contributions involve: optimal routing algorithms in the data centre network DPillar; significantly improved routing algorithms in the data centre networks HCN, BCN, DCell, FiConn, and recursively defined networks in general (in terms of hop-length, fault-tolerance, load-balancing, latency, and throughput); a new generic paradigm for the construction of dual-port data centre networks, namely stellar networks; and a flow-based simulator INRFlow that is geared specifically towards flow-based simulation in data centres *which has been essential to carry out all the evaluation work*. In addition, there has also been some contributions to other related communication architectures such as SpiNNaker's massively parallel architecture to novel, silicon-photonics interconnects and finally to FPGA-based modelling and simulation of interconnection networks. The interaction between two groups of researchers, one theoretical and one more applied, has been massively successful and a long-term collaboration has been established. The unique skill sets of both teams have been absolutely necessary to undertake the research.

Description There is potential for our results to be implemented in server-centric data centre networks when this paradigm moves from the university research domain and becomes more established within the builders of data centres. However, at present the switch-centric paradigm still dominates. INRFlow is currently being used as the core experimental environment within other related research projects and is being extended accordingly.
