An Efficient Shortest-Path Routing Algorithm in the Data Centre Network DPillar [chapter]

Alejandro Erickson, Abbas Eslami Kiasari, Javier Navaridas, Iain A. Stewart
2015 Lecture Notes in Computer Science  
DPillar has recently been proposed as a server-centric data centre network and is combinatorially related to the well-known wrapped butterfly network.  ...  We use this symmetry property to establish a single-path routing algorithm for DPillar that computes a shortest path and has time complexity O(k log(n)), where k parameterizes the dimension of DPillar  ...  Acknowledgement This work has been funded by the Engineering and Physical Sciences Research Council (EPSRC) through grants EP/K015680/1 and EP/K015699/1.  ...

An Optimal Single-Path Routing Algorithm in the Datacenter Network DPillar

Alejandro Erickson, Abbas E. Kiasari, Javier Navaridas, Iain A. Stewart
2017 IEEE Transactions on Parallel and Distributed Systems  
We use this symmetry property to establish a single-path routing algorithm for DPillar that computes a shortest path and has time complexity O(k), where k parameterizes the dimension of DPillar (we refer  ...  Moreover, our algorithm is trivial to implement, being essentially a conditional clause of numeric tests, and improves significantly upon a routing algorithm earlier employed for DPillar.  ...  We are also grateful for the insightful comments of the reviewers which helped to significantly improve this paper.  ...
