Speculative Traffic Redundancy Elimination for Cloud and Cellular Networks
In the last decade, traffic redundancy elimination (TRE) a new network bandwidth saving paradigm, has emerged and dominated enterprise networks. TRE based solutions also termed “WAN optimization” has been deployed in most enterprise networks, connecting data-centers with office branches. The transition to cloud based services and to smart mobile devices has made the current commercial solution inadequate. Their static topology and tight sender to receiver synchronization cannot cope with mobility, the elimination inline “special appliance” and the scarce resources of cellular networks. We present a new family of TRE that are based on speculative prediction. Unlike previous solutions, our scheme does not require the server to continuously maintain clients’ status. It is based on a novel TRE technique, which allows the client, the server or an intermediate gate ways to use newly received chunks to identify previously received chunk chains, which in turn can be used as reliable predictors to future transmitted chunks. This general approach is applied to both end-to-end TRE for cloud services as well as for reducing the traffic in cellular networks.

Bio: He is Tark chair Professor of Electrical Engineering at the Technion. He received the B.Sc. and D.Sc. degrees from EE Technion in 1980 and 1984 respectively. In 1981 he co-founded Micronet Ltd., a provider of mobile data-entry terminals. In 1985-94 he was a member and the manager of Network Architecture and Algorithms at IBM T. J. Watson Research Center, NY . We built the world first triple play packet network (and hardware router) and optical resilient packet rings (used at IBM . Serial Storage Architecture). In 1994-5 he founded and managed the high-speed networks group at Sun Microsystems Labs. In 1998 he co-founded Viola Networks the provider of NetAlly . a distributed network diagnostic platform (acquired by Fluke Networks in 2008). In 2000, he co-founded Actona Technologies (acquired by Cisco, 2004) that pioneered Wide Area File Systems (WAFS), WAN optimization and Wide Area Application Services (WAAS). In 2006-10 he was dean of Electrical Engineering at the Technion.
