A system and method for calculating and storing block fingerprints for data deduplication. A fingerprint extraction layer generates a fingerprint of a predefined size, e.g., 64 bits, for each data block stored by a storage system. Each fingerprint is stored in a fingerprint record, and the fingerprint records are, in turn, stored in a fingerprint database for access by the data deduplication module. The data deduplication module may periodically compare the fingerprints to identify duplicate fingerprints, which, in turn, indicate duplicate data blocks.

Methods, apparatuses and systems directed to the coordinated classification of network traffic. In one implementation, the present invention enables a coordinated network environment for traffic classification where an upstream network device classifies a data flow and adds traffic class information to at least one packet in the data flow. Downstream network devices in the communications path to the destination host can use the traffic class information in the modified packet, bypassing at least some of the local traffic classification operations and thereby reducing CPU utilization. In one implementation, the last downstream network device strips the traffic classification information from the modified packet before it is forwarded to the destination host. Embodiments of the invention reduce or eliminate redundant network traffic classification operations performed by a plurality of network devices in a communications path.

Synchronization of folders shared among multiple clients over a network is provided. A first user of a first client instantiates a folder to be shared, and the folder and its contents are synchronized with a host system. As the user makes changes to the folder and its contents on the first client, those changes are propagated to the synchronized version on the host server. Other clients who will be sharing the synchronized folder register with the host system and obtain a current version of the synchronized folder and contents. As the contents of the synchronized folder are changed by any of the clients, the changes are propagated to the host system, which in turn delivers the changes to each of the clients registered as sharing that folder. In this way, each client participating in the share has a current version of the folder and its contents.
