Technical Director, Plano, Texas, July 2001 - Current
Startup company developing innovative network security product for traversing VOIP traffic between enterprises and service providers. Responsible for the architecture, and redundancy design for 99.999 availability. Developed a new protocol for the redundancy of the SIP traffic as well as NAT and Firewalls. Lead the project from concept to realization. Devised a new technique for traversing VOIP traffic through enterprise Firewalls/NATS.
Technology Director, Richardson, Tx., Dec. 1999- June 2001
Developing leading edge networking products for Wireless Internet. Comprehended CDMA/2G/3G/Internet technologies and designed a cost effective Wireless Router. Ipmobile was acquired by Cisco in September of 2000. Initiated this strategic product for seamless integration of IP and wireless technologies. Responsible from inception to product design. Put together all the pieces in the puzzle (multiple disciplines include RF, CDMA, 3G, 3GPP2, IP, MPLS, DiffServ, SS7, IN, and VoIP technologies).
IP Competence Center, Principle Software Architect, Richardson, TX., June,1998- Nov. 1999
IP Routing/forwarding for Alcatel SONET/SS7-IP Products: Principle Software Architect for Alcatel SONET-IP Ring and SS7-IP Products. Study Phase2 Routing software (BGP, OSPF, RIP) for MPLS and QOS in ASICs. Designed new protocol for linking dynamic routing system and packet flow processor and analyzed the mechanisms for FIB/RIB table updates. Provided design for distributed IP routing in a SONET Ring, and IP packet level restoration in SONET Ring. Design of SS7-IP adaptation layer protocols (two patents pending). Contributed to IETF drafts on constraints based routing on MPLS (co-author) and Signaling Gateway protocol between media gateway and Media Gateway Controller.
Transport and Access Product Development, Principle System Designer, Richardson, TX., Dec. 1995 - May,1998
Hybrid STM-ATM-LAN services on the OC-3/12 SONET Ring Products: Team Leader and Principle System Designer for service (tributary) shelf in the hybrid ATM-SONET ring product. Responsible for the specification, detailed design for plug-in-units for LAN/ATM/FR and STM services. Design and integration of LANE/MPOA/MPLS and IP over SONET into current and new products. Represented Fujitsu in ATM Forum Standards.
Magellan Passport Software Development, Ottawa, 1990-1995
ATM SVC Connection Control for Cornerstone Residential Broadband Networks: Team Leader for research, design and software development of connection control for residential broadband networks.
ATM Traffic Management for Magellan Networks (in use for multi media application): Team leader for research, design and implementation of Access, Network and Node specific traffic control mechanisms for multi media applications in ATM networks.
Traffic Management for Release 1.0 Passport Frame-Cell-Switch (multimedia application): Responsible for overall research, design, and development. Work involves threshold interrupt handlers, queue polling mechanism, congestion status table and congestion broadcast mechanism.
Design and implementation of bandwidth management for Passport Frame Cell Switch: Verified the design using modeling and simulation for bandwidth enforcement algorithms for voice, video and data.
Intelligent Dial Backup Network links for Data Packet Network, DPN-100: Acting dial backup links for topological changes or during node isolation in the network. This feature is currently used in several customer sites. Highly successful project and received very good feedback from customers. Team leader for the project (team of 10 people).
