Recently, coding has been a useful technique to mitigate stragglers' effect in distributed computing. However, this context mainly explored assuming homogeneous workers, although real-world clusters often consist of heterogeneous workers with different computing capabilities. The uniform load allocation without considering the heterogeneity possibly causes significant loss latency. In article, ...

Data packet drop can happen in Optical Burst-Switched (OBS) when two data bursts are competing on the same wavelength. Recently, many techniques have been developed to solve this problem but they do not consider congestion. Also, it is necessary balance load system OBS network. The Ant Colony Optimization (ACO) technique be applied determine straight and safest route. However, ACO raises both p...
