As co-chair of the IETF Network Configuration (NETCONF) working group, responsible for charter, planning meetings, and shepherding documents thru the standardization process. The NETCONF working group is responsible for the development and maintenance of protocols such as NETCONF and RESTCONF for YANG data model-driven management (for the purposes of, for example, configuration, monitoring, telemetry, and zero-touch), their transports and encodings, defining data models necessary to support the protocols, and defining mechanisms supporting the operational deployment of systems using the protocols. The NETCONF protocol is data modeling language independent, but YANG (RFC 7950) is the recommended NETCONF data modeling language, which introduces advanced language features for configuration management.For more information, please see: https://datatracker.ietf.org/wg/netconf/about.

As co-chair of the IETF Network Modeling (NETMOD) working group, responsible for charter, planning meetings, and shepherding documents thru the standardization process. The NETMOD working group is responsible for the YANG data modeling language, which can be used to specify network management data models that are transported over such protocols as NETCONF and RESTCONF, and guidelines for developing YANG models. The NETMOD working group addresses topics related to the use of the YANG language and YANG models, for example, the mapping of YANG modeled data into various encodings. The NETMOD working group also defines core YANG models used as basic YANG building blocks, and YANG models that do not otherwise fall under the charter of any other IETF working group. The NETMOD WG may include work on YANG modules that do not otherwise fall under the charter of any other IETF working group.For more information, please see https://datatracker.ietf.org/wg/netmod/about.

Defined and standardized company-wide cross-product initiatives. Noteworthy RFCs: RFC 8040 (RESTCONF, named by Kent) used to define Juniper NMS product APIs; RFC 8071 (NETCONF Call Home and RESTCONF Call Home), standardizes the JUNOS "outbound-ssh" feature; RFC 8342: Network Management Datastore Architecture (NMDA); and RFC XXXX (Secure Zero Touch Provisioning (SZTP), which standardizes the ZTP protocol implemented by JUNOS.Served on the Juniper Patent Review Committee for over a decade.Member of the Cloud Services Platform Group, responsible for the development of the commercially-successful product "Contrail Service Orchestration (CSO)". CSO is primarily written in Python and Java. Helped define the CSO architecture, especially setting the high-level direction for it to be elastically-scalable using micro-services. For more information about CSO, please see: https://www.juniper.net/us/en/products-services /sdn/contrail/contrail-service-orchestration.While Kent helped define the architecture for this product, especially setting the high-level direction for it to be elastically-scalable using micro-services, Kent mostly devoted time to defining and standardizing company-wide initiatives.Three important IETF RFCs for protocols that Kent defined while at Juniper: RFC 8040 (RESTCONF), which Kent actually named, and is used to define the API for Juniper's NMS products; RFC 8071 (NETCONF Call Home and RESTCONF Call Home), which standardizes the JUNOS feature known as "outbound-ssh"; RFC 8342: Network Management Datastore Architecture (NMDA); and RFC XXXX (Secure Zero Touch Provisioning (SZTP), which standardizes the ZTP protocol implemented by JUNOS.Kent also served on the Juniper Patent Review Committee for over a decade.

An Architect of and contributor to the commercially successful Juniper network management product "JUNOS Space". JUNOS Space was written in Java, based on the J2EE application framework. For more information, please see: https://www.juniper.net /us/en/products-services/network-management/junos-space-platform.Also defined the Device Management Interface (DMI) used between Juniper NMS and JUNOS-based products. DMI was defined using the YANG data modeling language and the NETCONF management protocol.

Sole Architect of and a Principal Developer to the Juniper product "Network and Security Manager (NSM)", a highly-scalable, N-tier, distributed application composed of more than 2 million lines of Java, and C/C++ code maintained by nearly nearly 60 developers here and in India.After four years, NSM deployed by many Fortune 500 and Service Providers to manage their production networks. With excellent usability and scalability, it is currently considered best-in-class by many. This success has resulted in Juniper selecting NSM to be the management platform for all of its networking gear.NSM was challenging as it was necessary to bring together two existing NMS products: "Global Pro", which was already at NetScreen, and "IDP Manager" (Kent developed IDP Manager at OneSecure). For more information about NSM, please see https://support.juniper.net/support/eol/software/nsm.

Member of the technical advisory council for the OpenDaylight project, which develops "OpenDaylight", the largest open source SDN controller. OpenDaylight (ODL) is a modular open SDN platform for customizing and automating networks of any size and scale. For more information, please see https://www.opendaylight.org.

Upon NetScreen's acquisition of OneSecure, led the design and development of NetScreen's network management solution, which manifested as the product "NetScreen Security Manager (NSM)". After analyzing an exhaustive list of business and customer requirements, envisioned and promoted both NSM's scalable distributed server architecture and application-level conceptual model. Once the high-level design was accepted, led a team of about 35 developers in the construction of nearly a million lines of C and Java code.

Hired and managed team to develop the commercially successful product "IDP Manager". Co-designed and developed IDP Manager, a highly reliable and scalable C-based server for monitoring and managing customer network security devices. The management server was implemented using load-balanced server clusters distributed across two colocation facilities. When OneSecure changed its business plan from a "Managed Security Service Provider" (MSSP) to a network security product, my group repurposed the existing code and provided four successful software (CDROM-based) releases for both Linux & Solaris systems. Also wrote and maintained the source control server and the build system.

Principal research staff member responsible for the next version of "NPSNET", the software infrastructure supporting virtualization, simulation, visualization.Architected and co-developed "Bamboo", an open source, platform- and language- independent component framework for dynamically reconfigurable applications. While suitable for many domain- specific applications, Bamboo was developed to support online (24x7), large scale, networked virtual environments. Bamboo was first presented at the 1998 IEEE Virtual Reality Annual International Symposium (VRAIS '98) and was adopted by several academic, research, and commercial groups worldwide, including Internet 2's National Tele-Immersion Initiative and Sandia National Research Lab. This position included managing fellow research staff members, master students, and various open source developers.

Co-developed "EasyScene", a Performer-based virtual environment toolkit. Architected and implemented OpenSeas (the Marine Module), an EasyScene-based 3D ocean model and ship simulator. Architected and implemented EasyMotion (the Character Animation Module), an EasyScene-based 3D character animation package. Directed and implemented "HellenicKombat", an EasyMotion-based mythological fighting game. Researched and developed a physically-based dynamic flag simulator. Wrote VME device drivers for the Saturn car-driving simulator. Code written in C/C++.

Lead graphics and modeling engineer in the implementation of Distributed Interactive Simulation (DIS) compliant modules used by the US Army Tank-Automotive Command's vehicle simulation facility. All modules written in C++ and integrated into an object-oriented, multi-processed, real-time architecture on networked Silicon Graphics Onyx platforms. Designed and developed Visual World, a general purpose, Performer/GL-based, DIS- compliant visualization toolkit. Researched and implemented the Transform class to convert coordinates, vectors, and orientations expressed in WGS84 topocentric, geodetic, and geocentric euclidean space systems. Performed a comprehensive survey of 3-D audio algorithms and hardware implementations. Designed and developed the ADRG Map Tool, an X Windows/Motif-based application used to extract and save images from DMA Arc Digitized Raster Graphics (ADRG) compact disks. Modeled the Hunter Liggett terrain database complete with geo-specific cultural features.
