million dollar) consisting of 7 contributing members that aims to build an
of the IPv6-based IMS/
IPv6 Transition with CERDEC
· As the project manager and PI of the IPV6 transition project (500 K) with CERDEC consisting of 5 contributing members, I was responsible for every operational aspect of the project including customer interaction, regular telecon with the customer, meeting with the project team members, design and development of the deliverables, software delivery and demos at customer site.
TOSHIBA MOBILITY PROJECT:
· Acted as Technical Lead for the design of a Third Generation (3G) Mobile Wireless Internet Architecture (IMT-2000) based on CDMA-2000 standard and its transition to 4G network (WiFi) as part of a joint research project between Telcordia and Toshiba. As part of ITSUMO (Internet Technologies Supporting Universal Mobile Operations) project involved primarily in technical lead role for secure and seamless mobility management, localized multicast and session control signaling part of the architecture that includes Mobile IP, SIP, SAP, RTSP, SDP and IPv6. Took a lead role in designing, directing and implementing an all IP Mobile multimedia comprehensive test-bed involving many Linux based systems, Cisco routers and several subnets to demonstrate micro, macro and global mobility including AAA functionality and application layer mobility management such as SIP-based mobility in a 802.11B environment. Many of the features for Wireless Internet Telephony and Streaming Multimedia such as signaling, registration, binding, location management, AAA, and QoS have been prototyped in this testbed.
· Took a leading role in design of secure and seamless handover between heterogeneous access networks e.g., between packet switch (Wi-Fi) and circuit switched networks (GPRS, CDMA) for the dual mode handsets. Above tasks have resulted in about 20 paper publication and 5 patent applications and 10 IETF drafts.
· As one of the Co-Principal Investigators (Co-PI) for DARPA ACN project (2.5 million dollar), led in writing the winning proposal for Integrated Mobility Management for phase II and phase III, and have been acting as a Technical lead for the Integrated Mobility Management part of the project. This involved designing and implementing an Integrated Mobility Management scheme for Adhoc type military networks while coordinating between different task groups, presenting regular milestone reviews at DARPA meetings.
· As a technical lead for a DARPA funded AJCN project (1.5 million dollar), involved in the design, development and prototype demonstration of a SIP based multiparty conference control using both multicast and MCU based approaches aided by SIP’s third-party call control features. Above two have resulted in 10 paper publication and 3 patent application
· As the technical lead for DARPA’s National Cyber Range (NCR) IMS task designed and architected IMS testbed and designed the interface between IMS and PSTN. This activity includes interconnection of IMS testbeds at different locations connected by VPN.
· As the technical lead for National Communication System (NCS)’s multi provider service provider testbed, led a group that designed and architected priority services for VoIP and streaming services over an IMS using GETS (Government Emergency Telecommunications Service) requirement. This activity involved designing priority-based services at layer 2, layer 3 and SIP layer.

protocols (SIP, RTP, RTSP, SDP, MGCP) and TINA-C to
support VoIP and multi-party and multi-media features over IP or ATM based
network. This included the design of end-to-end call flows for establishing the
sessions. This work was done for the Regional Bell Operating Companies and
other international clients who are planning to build the multi-service
platform. Some of the clients included KT, BellSouth, SBC, Telenor,
¨ As part of ITSUMO QoS team involved in performance analysis of voice and data traffic in an 802.11b networking environment using diffserv priority queuing, traffic control mechanism and Spectra Link Voice Priority (SVP) that provides marking at the MAC layer. Under simulated multiple user environments, packet loss, delay and jitter measurement was evaluated.
¨ Performed a feasibility study for supporting IPv6 in an Ad Hoc environment. This involved looking at the issues such as mobility, signaling, configuration.
¨ As part of Network Appliance project involved in the design and implementation of SIP User Agent, SIP proxy to control the appliances which are behind the residential gateway. This may involve proposing some extensions to SIP specifications.
¨ Performance Analysis of SS7 signaling over TCP/IP for VoIP type of services. This was analyzed using IP’s differentiated services (WFQ) on a Cisco 7500 series router and a range of UDP crosses traffic.
