Industrial Activities

Manager of Network Architectures and Algorithms at IBM T.J. Watson Research Center, NY: Leading a research group high speed network architectures, distributed algorithms, network performance and a networking hardware implementation. The main projects of the group were:
o    The PARIS project – The PARIS prototype (completed in 1987) supported data, voice and video real-time communication over 100Mbps links. PARIS was the world first hardware based router implementing a wide area converged network to carry voice, video and data over high-speed hardware based packet switched infrastructure. A gigabit version of PARIS (plaNET) was part of the national NSF/DARPA funded Aurora gigabit test-bed connecting several research centers in the US. Leading networking textbooks like the Bertsekas & Gallager "Data Networking" and Craig Partridge "Gigabit Networks" dedicated sections to the PARIS/plaNET technologies. Many novel aspects of PARIS were adopted by the ATM standards (e.g. dual leaky bucket, traffic engineering) and the MPLS standards.
o    The Metaring project –the first optical LAN/MAN based on buffer insertion ring with spatial reuse and integrated fairness and (completed in 1988). A gigabit version of Metaring was part of the US information superhighway test-beds. The architecture, protocols and the fairness algorithm of the Metaring have been used by the SSA (Serial Storage Architecture) standard (ANSI Standard X3T10.1/989D) for the connection of storage devices in large systems. This is the world first Storage Area Network (SAN) based on packet switching technology. Cisco Resilient Packet Ring (RPR) and IEEE 802.17 also adopted the Metaring basic architecture for metropolitan broadband networks.
 
Manager of High Speed Networking at Sun Microsystems Labs, CA (1994-5): Initiating and managing a research group in the area of high speed networking. Activities include: OPENET – an open and efficient ATM network control platform. Design and prototype of an ATM/Ethernet switching core on chip based on active ring technology (adopted by PMC Sierra).
 
Co-founder and Chief Scientist for Actona Technologies: Along with Dr. I. Ben-Shaul and Dr. I. Kessler, innovated and architected an enterprise wide area file System (WAFS) that connects and accelerates remote access to file systems (CIFS, NFS) via the WAN using distributed peer-to-peer network of read/write caches. The product allows branch offices to locate their file system in the data-center eliminating local file servers and backup. In June 2004, Actona Technologies was acquired by Cisco for $100M and its technology is sold now under the name WAAS (wide area application services). In 2007 Cisco reported the 1000th customer for this technology. The current world market for WAFS and WAAS (also termed WAN Optimization) is estimated to be $1.5B per year of which Cisco holds around $300M per year.
 
Co-founder and Chief Technology Officer for Viola Networks: Along with Prof. Moshe Sidi, initiating and leading the architecture and definition of NetAlly, the first distributed network performance fault isolation system based on active network testing and end-through-end analysis, NetAlly is operational at several hundreds customers including tier one service providers. It was acquired by Fluke Networks in 2008.
 
- Micronet and Mechkam Technologies (1977-1985): Was responsible for the hardware development at both companies. Leading R&D for the following products: data entry PDAs, bar-code scanners and readers, communication protocol converters and multiplexers, field time attendance readers etc. A co-founders of Micronet Ltd. a vendor of mobile data-entry equipment.
 
Network on Chip and Chip Multi-processors (2003-now): Along with Prof. Ginosar, Prof. Keidar and Prof. Kolodny founded the activity in NoCs and CMP at the department and established the MATRICS project that is one of the leading and early groups in these areas. We have established the first international conference in this area (NOCS) which has already reached his third year. Our work on QNoC, a novel NoC architecture that includes QoS support and heterogeneous link capacities has gained a large number of citations and is now implemented by Qualcomm for future NoC based products.
