Research:

My research interests include both theoretical and practical aspects of distributed computing. In particular, peer-to-peer systems, scalable pub/sub communciation, fault-tolerance and high availability in a variety of settings, distributed middelware and service oriented computing (aka SOA), reliable storage systems, shared memory, and group-communication.

Some past and present projects I am/was involved in:

• FRAPPE: Fast Replication Platform for Elastic Services: ongoing. WIP paper published in LADIS 2011.

• Multi-tenant Cloud Caching Service: In special issue on cloud computing of the IBM Journal of Research and Development: vol 55(6), 2011, PDF

• CoMiFin (EU/FP7): Middleware for Protecting Critical Financial Infrastructure. Principal Investigator.

• Bulletin Board: Large Scale Communication System for Monitoring Applications (IBM). Awarded Outstanding Technical Accomplishment.
  For more details see the following paper presented at ACM/SIGOPS LADIS 2009:
  Bortnikov, V., Chockler, G., Roytman, A., and Spreitzer, M. 2010. Bulletin board: a scalable and robust eventually consistent shared memory over a peer-to-peer overlay. SIGOPS Operating Systems Review 44, 2 (Apr. 2010), 64-70. DOI= http://doi.acm.org/10.1145/1773912.1773929

• Scalable Group Communication and Publish/Subscribe Systems: I've been working on scalable group communication and pub/sub ever since I joined IBM in 2005. The results to date include the following (links to the papers will follow later):
  SpiderCast: with Melamed, Tock, and Vitenberg, published in DEBS'07
  Overlay network design for pub/sub: with Melamed, Tock and Vitenberg, published in PODC'07
  Distributed subscription clustering: with Shraer, Keidar, Melamed, Tock, and Vitenberg, published in DSN'07 (fast abstract), Locality 2007
  Bulletin Board: Shared Memory Style Pub/Sub: with Bortnikov, Roytman, and Spreitzer, published in Operating Systems Review (LADIS'09)
  Dr. Multicast: IP Multicast in Data Centers: with Vigfusson, Birman, Abu-Libdeh, Balakrishnan, Li, Tock, published in Eurosys 2010
  Magnet and Gravity: Clustered Pub/Sub over DHT-like Overlays: with Gidzijauskas, Vigfusson, Tock and Melamed, fast abstract in DEBS 2008, full paper in DEBS 2010

• Middleware for robust applications in wireless ad-hoc networks (MIT): An overview paper, tutorial slides.

• A unified fraemwork for specifying and proving atomicity (MIT): Research abstract

• Aquarius (Hebrew University): A quorum based fault-tolerance infastructure for CORBA

• Object Store over SAN (IBM): Storage controller supporting object level access to networked storage devices
