MOSE: A Novel Orchestration Framework for Stateful Microservice Migration at the Edge
Stateful migration has emerged as the dominant technology to support microservice mobility at the network edge while ensuring a satisfying experience to mobile end users. This work addresses two pivotal challenges, namely, the implementation and the orchestration of the migration process. We first introduce a novel framework that efficiently implements stateful migration and effectively orchestrates the migration process by fulfilling both network and application KPI targets. Through experiment…

Things I enjoy: adding a new ring address across the cluster. Since I added the migration network post-cluster creation it couldn't being used by `corosync` in case something tragic happened. Also, it meant that if you added a new node to the cluster it wouldn't verify that the migration network was online on the new node when it brought it into the cluster. However, solved that pretty fast by just adding it as a `ringX` entry (in this case `ring3`) to all the nodes and enabled it…

I know as a developer just how hard it is to actually make it work, but perhaps the lesson of the Liquid Glass public reaction fiasco is for Apple to just give users •much• more control over the UI theme.

Optimal Task Offloading with Firm Deadlines for Mobile Edge Computing Systems
Under a dramatic increase in mobile data traffic, a promising solution for edge computing systems to maintain their local service is the task migration that may be implemented by means of Autonomous mobile agents (AMA). In designing an optimal scheme for task offloading to AMA, we define a system cost as a minimization objective function that comprises two parts. First, an offloading cost which can be interpreted as the cost of using computational resources from the AMA. Second, a penalty cost …

The monitor survey is depth migrated with the known velocity model of the base survey. An analysis is performed to determine whether the moveout to be expected for the monitor survey after residual prestack depth migration (RPSM) can be used for the velocity determination of the formation of interest. In that case the migrated response for the base horizon of the monitor survey …

Theory of cell size regulation during migration in adhered cells
Cell migration is closely linked to cell shape, yet cell size is often assumed to remain constant. This assumption is challenged by recent experiments showing that cells undergo volume loss during spreading and swelling upon activation, with migration velocity correlated to cell size. In this Letter, we present a minimal theoretical framework for cellular size regulation and its influence on migration velocity. We connect cell size to membrane potential and active, actin-driven forces. Spatial …
