CloudPath: A Multi-Tier Edge Computing Framework

Current mobile networks are not able to support next generation applications that require low latency, or that produce large volumes of data that can overwhelm the network infrastructure in a carrier network. Examples include intelligent personal assistants and home automation services, medical patient monitoring, safety-critical applications such as face recognition applications for airport security and surveillance, and intelligent transportation systems. To address these challenges, the research community and the telecommunications industry are exploring ways to add computation and storage capabilities to the edge of the network. These approaches, variously referred to as cloudlets, micro data centers, or fog, augment the traditional cloud architecture with an additional layer of servers that are located closer to the end user, typically one-hop away.  

CloudPath is a new platform which generalizes the edge computing vision into a multi-tier cloud architecture deployed over the geographic span of the network. The platform supports scalable processing by providing storage and computation along a succession of datacenters of increasing sizes, positioned between the client device and the traditional wide-area cloud datacenter.  CloudPath consists of an execution environment that enables the dynamic installation of light-weight stateless event handlers, and a distributed storage system that dynamically replicates application data.  CloudPath handlers are small, allowing them to be rapidly instantiated on demand on any server that runs the CloudPath execution framework. In turn, CloudPath automatically migrates application data across the multiple datacenter tiers to optimize access latency and reduce bandwidth consumption.
