Storage management cost is one of the most important issues in the current computer system. Network storage is deployed in many companies to decrease this cost. In the network storage system, both the server computer and network storage have cache memory for the same storage. In most cache implementation, LRU replacement algorithm, which is suitable for accesses with temporal locality of reference,...
In a cloud computing environment, virtual machines are migrated with two kind of methods. One is non-live migration, and the other is live migration. In case of non-live migration, a virtual machine stops their processes during migrations. In case of live migration, a virtual machine and its processes keep running during migration, but their performance may severely decrease. In order to obtain better...
In recent years, as the data processed by governmental or commercial organizations increases, cases involving information leak have risen. It is difficult to control information on many distributed end-point computers using conventional security mechanisms. Therefore, we have been proposed a novel secure VMM (Virtual Machine Monitor) architecture which is used as a foundation of security policy enforcement...
This paper discusses a security mechanism for an inter-device communication paradigm. Future networked devices interact with each other and a federation of devices will provide some useful services to users. This paper first introduces the inter-device communication paradigm and prospective industrial applications. This paper shows technical features and security problems on the inter-device communication...
