Scaling redundancy elimination middleboxes

摘要

A capability is provided for scaling Redundancy Elimination (RE) middleboxes. The RE middleboxes include an RE encoding middlebox and an RE decoding middlebox. The RE middleboxes may employ max-match-based RE techniques or chunk-match-based RE techniques. The RE middleboxes may utilize Distributed Hash Tables (DHTs) to maintain content stores, respectively. The RE middleboxes may be scaled for use with cloud applications (e.g., for use in transfer of data between a customer network and a cloud side, for use in transfer of data between two cloud sites, or the like).

1. An apparatus, comprising:
a set of data processing modules comprising a first data processing module and a second data processing module, the first data processing module and the second data processing module each configured to support a set of redundancy elimination (RE) processing functions; the first data processing module configured to process a packet using a first set of RE processing functions from the set of RE processing functions, and to propagate the packet toward the second data processing module; and the second data processing module configured to receive the packet from the first data processing module, and to process the packet using a second set of RE processing functions from the set of RE processing functions.
