For over a quarter century Dr. Walker has contributed directly to the project, the team, and his employers' success in terms of product-market penetration, acceptance, sustaining, and a keen awareness of the financial and base-line market issues. All the while, as part of an ongoing process, adding to the variety of computer business related skills, the discipline in general, while accruing new experience Dr. Walker describes as "The stuff that keeps it exciting, keep me enthusiastic, looking forward, coming back, and sure... the compensation is great!".

Dr. Walker's credits include the IBM Large Systems Service Processsor Architecture and Design which implements amoung other features Exigent Error Recovery, Extended I/O Error Logout and Reporting for the IBM System 370 through 390 Processors and the 37x5 Series of FEPs. Software Development Credits include MVS, VM, VSE, AIX Dispatcher-Scheduling, Low Level I/O, I/O Error Recovery and Logging. Dr. Walker's interest and experience since 1989 have focused on embedded communications systems. Before leaving IBM, Dr. Walker was a senior member of the development team responsible for the successful implementation of the ADMS Distributed Document Management Systems. The ADMS System brought together the power of the IBM Mainframe, the Personal Computer, MVS, VM, UNIX, and other proprietary LAN and WAN attached Document Scanning, Storage, Reproduction and Management Workstations. In addition, ADMS led to NDMS, The Navy Document Management System. The same basic design as ADMS rearchitected to meet the U.S. Navys look, feel, and security requirements.

Leaving California and IBM, Dr. Walker relocated to Southern Florida and Motorola Corporation, Personal Communication Systems Subscriber Sector. At PCS Subscriber his responsibilities included the TDMA-IC (an ASIC upon which the Time Division Multiplexing implements uCellular Bearer Services) and the Central Cell Site Control and Console of the Motorola D.E.C.T. (European Standard) and S.H.A.R.E. (American Standard) implementations of the Phoenix Micro-cellular Telephone System Prototype.

PCS Subscriber relocated from Plantation, Florida to Fort Worth, Texas in 1995; then to Schaumberg, Illinois in 1996. Dr. Walker elected to remain in South Florida transitioned from PCS Subscriber to CPS, the Computer Products Sector in 1995. "I literally turned out the lights as I closed the door!".

Dr. Walker has been a significant contributor to two projects since joining CPS. The first was Layers Three and Four of the HTMS 3400 Network Attached SNA LU 6.2 Tokenring V.34 Modem. The project concluded successfully after one year on time and under budget earning revenue in excess of those originally anticipated. With the completion of the HTMS 3400 R&D, the second and ongoing project, Motorola's new line of Fast Frame Relay Access Nodes received approval and funding. As Senior Architect and Mananger of Fast Frame Relay, Motorola's second generation of Frame Relay Access Devices, the challenge to significantly improve and extend the features and reach of the original Product. These features included a Frame Relay Device which supported 4 Enterprise Devices and up to 2 LAN and 1 WAN or 1 LAN and 2 WAN devices. The 2 LAN Architectures Supported are Tokenring and Ethernet. The WAN Architectures Supported include T1-E1, T3-E3, BRI-PRI-ISDN, V.22bis, V.34+ addon internal user selectable features implemented as modular addons. Asynch, bisynch, synchronous, in short, all popular hardware adaptation layers are supported. Each maybe configured independantly as a DTE or a DCEs. The customary suite of Frame Relay protocols are extended using standardized encapsulation (tunneling) to include ACF/ATP, ACF/SNA, SLIP, PPP, LL2, IPX, SPX, ISDN, X.25, ATM acting as either bridge, router, or switch. User defined Qualility Of Service and Committed Information Rate as well Bandwidth On Demand, Priority Queuing, Dynamic ISDN Channel Allocation and Dial-Around-The-Cloud using standard Ethernet SNAP and Frame Relay Encapsulation technology. Each Frame Relay Access Node or Device includes automatic and/or user configuration control and management, Full SNMP Agent-Manager and Realtime Protocol Trace implemented using an attached TTY, glass TTY, or any PC capable of Emulating Digital Equipment VT-100, VT-220, and ANSI emulation.

Dr. Walker is a team player and brings to each project his broad experience, unique perspective, interpersonal and technical skills, enthusiasm, sense of humor, and willingness to share the load.

On a closing note, Dr. Walker on behalf of himself, Motorola, and CPS has spent considerable time and energy getting on the right side of the Linux-UNIX-OSI industry. Dr. Walker has been and remains a frequent contributor to the Linux-UNIX Open Source Community. With contributions ranging from kernel, kernelspace, userspace, network code, functional scripts that extend and enhance the Linux-UNIX workplace environment; each designed and implemented to be easily portable across a wide variety of platforms. If your a Linux-UNIX user you may already be taking advantage of his generous contributions. Particularly if your interested in Stable, Efficient, Secure, Reliable, easy to recover Linux, BSD, other *NIX platforms in and around your office and/or home. Dr. Walker has been recognized publicly on several occasions for his enthusiasm and contributions and is often sought to provide a correct solution out of the gate at the right price.
