Пълно описание

This thesis investigates the efficiency of§extent-based allocator design to satisfy file§allocation requests in a CDN proxy cache. The§allocator is based on the method inspired by the§memory allocators, where free space is managed in§chunks of varying size, or extents. The design is§tested in a simulation, where a trace of allocation§and deallocation events from a content server was§submitted to the allocator. The bottleneck for§content retrieval often lies on data transfer rates§of the hard disks used in the server. To facilitate§fastest possible transfer of a file, it must be read§sequentially. At the same time, given the large§quantity of files, space wastage due to incomplete§utilisation of large allocation units is not§desirable. Our allocator design tries to achieve both§mutually exclusive goals. The design was implemented§and the results we obtained in the course of§simulation, show that we managed to achieve these§goals, creating an allocator that displays§properties, favourable for contiguous file placement,§while keeping space wastage at its minimum.
