Abstract: Recently, the software-defined networks (SDNs) are the most promising architecture which are mainly composed of the Openflow switches and the Flowvisor. The SDN provides virtualized separate networks as slices on a physical network according to the customer needs. The Flowvisor can provide customers to have their own controller and let the controller handle flow packets in its slice –a virtual network. In this paper we proposes a policy based slice embedding and have deployed a prototype in a virtualized testbed on KREONET – a Korean R and E network. The slice embedding system is designed as a part of aggregation management system to administer our testbed as interact with Flowvisor and slices can be automatically assigned by network resource provisioning with decision of Policy based Engineering (PBE) module in the system. Several points are considered to make policies for slicing so that slice embedding service for provisioning virtualized networks could be automatically deployable.

Abstract: In this article the possible use of smartphones, as potential resources in a distributed computing system has been examined. First, the performance indexes of smartphones, desktop and notebook computers were compared, considering the six year period of the iPhone product line. In the second part some volunteer computing projects were summarized in a glance, to have a better picture of the necessary performance and donation system. Finally some motivating ideas have been proposed, to gather more donors for a smartphone based distributed computing network.
