A protection routing with secure mechanism in the data center network WaveCube

In the era of information explosion, the scale of data center networks (DCNs) has expanded exponentially, consequently leading to an inevitable increase in server failures. Therefore, how to ensure the efficient and secure operation of the network has emerged as a critically important research topic. WaveCube is a scalable, fault-tolerant, high-performance optical DCN architecture. In this paper, we first propose a local secure model (LS model) of WaveCube. This model segments fault-free nodes within sub-Wavecube by imposing specific constraints, thereby adeptly circumventing potential communication impediments that could arise due to faulty nodes. Secondly, based on this model, we design a protection routing with secure mechanism to ensure stable communication within WaveCube. Finally, we perform a series of experiments, and the results show that when the number of faulty nodes is less than half of the number of total nodes, the hit rate can reach nearly 100%, while the shortest path rate can achieve up to 90%.
