ShAir: extensible middleware for mobile peer-to-peer resource sharing

Abstract: ShAir is a middleware infrastructure that allows mobile applications to share resources of their devices (e.g., data, storage, connectivity, computation) in a transparent way. The goals of ShAir are: (i) abstracting the creation and maintenance of opportunistic delay-tolerant peer-to-peer networks; (ii) being decoupled from the actual hardware and network platform; (iii) extensibility in terms of supported hardware, protocols, and on the type of resources that can be shared; (iv) being capable of self-adapting at run-time; (v) enabling the development of applications that are easier to design, test, and simulate. In this paper we discuss the design, extensibility, and maintainability of the ShAir middleware, and how to use it as a platform for collaborative resource-sharing applications. Finally we show our experience in designing and testing a file-sharing application.

Fixed and mobile convergence: which role for optical networks?

Abstract: The current level of pooling and sharing between fixed and mobile infrastructures is not sufficient to allow the most efficient use of network resources, whether fixed, mobile, or Wi-Fi. In the perspective of 5G networks, efficient resource sharing of fixed and mobile infrastructures, called structural convergence, will be essential in the path toward an integrated fixed and mobile network. This structural convergence is being triggered by different architecture trends, e.g., baseband unit hostelling and mobile fronthaul technologies, heterogeneous radio access networks, and, most importantly, a unified optical access and aggregation network. The COMBO European project is studying architectural options for structural convergence leveraging on the aforementioned technological triggers and in particular on the evolution of optical access and aggregation technologies. These architectural options are described and analyzed with respect to anticipated needs for integrated fixed and mobile networks.

Architectural considerations for next generation file systems

Abstract: We evaluate two architectural alternatives—partitioned and integrated—for designing next generation file systems. Whereas a partitioned server employs a separate file system for each application class, an integrated file server multiplexes its resources among all application classes; we evaluate the performance of the two architectures with respect to sharing of disk bandwidth among the application classes. We show that although the problem of sharing disk bandwidth in integrated file systems is conceptually similar to that of sharing network link bandwidth in integrated services networks, the arguments that demonstrate the superiority of integrated services networks over separate networks are not applicable to file systems. Furthermore, we show that: (i) an integrated server outperforms the partitioned server in a large operating region and has slightly worse performance in the remaining region, (ii) the capacity of an integrated server is larger than that of the partitioned server, and (iii) an integrated server outperforms the partitioned server by up to a factor of 6 in the presence of bursty workloads.

Sharing with performance isolation between tenants in a software-as-a service system

Abstract: An apparatus hosting a multi-tenant software-as-a-service (SaaS) system maximizes resource sharing capability of the SaaS system. The apparatus receives service requests from multiple users belonging to different tenants of the multi-tenant SaaS system. The apparatus partitions the resources in the SaaS system into different resource groups. Each resource group handles a category of the service requests. The apparatus estimates costs of the service requests of the users. The apparatus dispatches service requests to resource groups according to the estimated costs, whereby the resources are shared, among the users, without impacting each other.

Asynchronous arbiter state machine for arbitrating between operating devices requesting access to a shared resource

Abstract: A system has a shared resource, such as a bus or memory, with which various devices may communicate upon a request being granted by an arbiter. In order to reduce the arbitration time, the arbiter is comprised of a state machine and latch which run asynchronously. Consequently, once one request has been granted and acted upon, the state machine will commence arbitration for any remaining requests.
