Abstract: Embodiments of the present invention provide a method, system and computer program product for dynamic caching module selection for optimized data deduplication. In an embodiment of the invention, a method for dynamic caching module selection for optimized data deduplication is provided. The method includes processing historically relevant byte streams in each of a multiplicity of byte caching modules to populate a table of associations between different classifications of the historically relevant byte streams and correspondingly optimal ones of the multiplicity of the byte caching modules. The method also includes receiving a request to retrieve data from a data source and classifying the request. The method yet further includes consulting the table to identify, from amongst the multiplicity of byte caching modules, a particular byte caching module associated with the classification of the request. Finally, the method includes deduplicating the data in the identified byte caching module.

In an embodiment of the invention, a method for dynamic caching module selection for optimized data deduplication is provided. The method includes receiving a request to retrieve data and classifying the request. The method also includes identifying from amongst multiple different caching modules each with a different configuration a particular caching module associated with the classification of the request. Finally, the method includes deduplicating the data in the identified caching module.

Abstract: Distributed data deduplication may include or utilize containers attached to nodes or byte caches in a cluster or enterprise networks. The containers may store a mapping of byte caches and hashes the byte caches hold. An encoding byte cache may communicate with its attached container to determine which nodes should send which hash values, and may encode an output stream accordingly. Decoding byte cache decompresses the output stream by communicating with its attached container for receiving hash values and associated content from one or more byte caches specified in the output stream.

Abstract: Disclosed is a novel passive fingerprinting technique based on DHCP messages to determine the device type and operating system. DHCP implementations are shown to vary among device types and have an effect on DHCP lease durations. To improve network address utilization, without introducing any protocol changes, the present invention provides a new leasing strategy which takes into account device types. This strategy, compared to current approaches, improves the address utilization sixfold without considerably increasing DHCP overhead.
