摘要： Methods and systems for performance inference include inferring an internal application status based on a unified call stack trace that includes both user and kernel information by inferring user function instances. A calling context encoding is generated that includes information regarding function calling paths. The analysis includes performing a top-down latency breakdown and ranking calling contexts according to how costly each function calling path is.

摘要： A method is providing for provisioning time-varying traffic demands in an optical transport software-defined network. The method includes pre-provisioning an amount of bandwidth for best effort traffic. The method further includes iteratively applying, using a processor, an iterative simulated annealing-based traffic provisioning procedure to determine candidate bandwidths for the best effort traffic in a set of iterations. The method also includes selecting a particular candidate bandwidth that has a corresponding blocking value lower than a given blocking requirement β and that requires a minimum amount of spectrum as compared to other candidate bandwidths. The iteratively applying step includes varying the amount of bandwidth for best effort traffic in each iteration to determine the candidate bandwidth. The iteratively applying step further includes varying an amount of shared bandwidth between neighboring channels, out of the amount of bandwidth for best effort traffic, in each iteration, to further determine the candidate bandwidths.
