Seamless Live Virtual Machine Migration with Cloudlets and Multipath TCP
Bibliographic record
Abstract
Techniques using a nearby virtual machine (VM) based cloudlet have been proposed for mobile cloud computing (MCC) to enhance the performance of real-time resource-intensive mobile applications. After a mobile device (MD) discovers a cloudlet in the vicinity, it takes time to set up a VM inside the cloudlet before data offloading from the MD to the VM starts. The time between discovering the cloudlet and actual offloading of data is considered as a service initiation time. When multiple cloudlets are presented in a nearby geographical location, initiating a service with each cloudlet may be frustrating for cloudlet users when changing location. In order to eliminate the delay caused by the service initiation time after moving away from the source cloudlet, this paper proposed a seamless live VM migration between neighbour cloudlets. A seamless live VM migration is achieved with the prior knowledge of the migrating VM IP address in the destination cloudlet and more importantly with multipath TCP (MPTCP). We have performed a number of experiments to validate the proposed approach using the Linux KVM hyper visor. The experimental results demonstrate the feasibility of the proposed approach and also performance improvement. Specifically, there is zero downtime at the destination cloudlet after the migration is completed.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
