In context of Machine Type Communication (MTC) applications, network has to face increased load as well as possible surges of MTC traffic due to massive concurrent data and signaling transmission, in which case the interarrival time distribution of MTC devices may follow Beta distribution. In this paper, we model the network with MTC applications as a Beta/M/1 queue model. By deducing the moment generation...
Virtual machine (VM) provisioning is one of the fundamental components in virtualization-based cloud offerings. Modeling and analytically understanding the provisioning process is critical for the deployment and management of large-scale cloud. Based on extensive experiments on an example cloud system, we propose a queueing model to capture the important features related to scalability for the provisioning...
Distributed systems with multi-stage workflows are characterized by multiple logical stages which can either execute sequentially or concurrently and a single stage can be executed on one or more physical nodes. Knowing the mapping of logical stages to physical nodes is important to characterize performance and study resource bottlenecks. Often due to the physical magnitude of such systems and complexity...
