This thesis investigates the efficiency ofextent-based allocator design to satisfy fileallocation requests in a CDN proxy cache. Theallocator is based on the method inspired by thememory allocators, where free space is managed inchunks of varying size, or extents. The design istested in a simulation, where a trace of allocationand deallocation events from a content server wassubmitted to the allocator. The bottleneck forcontent retrieval often lies on data transfer ratesof the hard disks used in the server. To facilitatefastest possible transfer of a file, it must be readsequentially. At the s...
