TurnKey Integration & Protocol Enhancement |
For a Fortune 10 corporation, was responsible for the design and
implementation of software necessary to permit MicroVAX systems using
VAX/VMS and DECnet to utilize dial-up connections to a public
packet switched data network (not designed for use with computer-computer
communications). Implementation of this required modifications at the DDCMP
level, which permitted the chain of elements (MicroVAXes, PSDN, X.25 PADs) to
correctly transmit data bidirectionally. Effort was successful in an elapsed
time of two weeks (six weeks part time including equipment procurement for
demonstrator system). Client staff had previously projected a multiple
man-year effort.
|
System Deployment |
For a measurement equipment manufacturer, was responsible for the
setup and installation of Pathworks and DECnet facilities on an Ethernet LAN
located in the Far East. The installation included full installation of
Pathworks and DECnet in a "no support environment" (no outside telephone, no
outside technical support available in any way). The installation and
troubleshooting was completed without incident. Was engaged for this field
expedition after technicians originally tasked for this matter found it not
possible to install product without outside technical support.
|
Network Performance |
For a major non-profit agency, have performed performance analysis and
troubleshooting relating to their Pathworks network, which includes over 90
MS-DOS based personal computers and supporting infrastructure. Have identified
problems with the installation of the network which resulted in excessive
collisions on the Ethernet and reduced Pathworks performance. Also reviewed
the performance issues pending on the ALPHA and VAX systems being used to
support the Pathworks environment.
|
Callable Libraries and Realtime Applications |
For an OEM, designed and implemented applications libraries to allow
applications utilities to connect to and manage devices physically plugged
into the MS-DOS based workstations. This communications project required the
implementation of library routines (on the VMS host) and a server (on the
MS-DOS systems) to establish, manage, coordinate, and release DECnet logical
links between the host and server systems. DECnet-VAX was used on the host.
The servers were MS-DOS personal computers using Pathworks.
|
Network Maintenance |
Have maintained inhouse and clients networks including DECnet-VMS,
DECnet-11M/M+, DECnet/POS, DECnet-DOS, Pathworks and various TCP/IP
implementations operating on a mixture of
asynchronous serial connections and Ethernet LAN for several years.
|
Protocol & Network Analysis |
For a major computer company, have been responsible for a project,
using OpenVMS 6.1 and Pathworks 5.0 and 5.1 to test the behavior of software
products in that environment. The test environment has involved the
installation of a 6 node network in our laboratory, together with programming
at both the DECnet Logical Link level and the LATdriver (OpenVMS) and the LAT
API level (Pathworks).
|
Setup & Installation |
For an educational institution, have setup and installed lab
environment consisting of Pathworks and OpenVMS server.
|
Troubleshooting |
For the R&D center of a major chemical firm, have isolated,
identified, and corrected problems with their Ethernet LAN which had
previously defied solution by customer, LAN integrator, and LAN vendor staff.
The problem had resulted in the facility wide LAN (400+ employee, 4 square
block facility) becoming unavailable, with no warning, several times a day.
|
TCP/IP |
For various clients, have been involved with the Internet (and its
predecessor, the Arpanet) since 1978. Have worked with TCP/IP and related
protocols, SMTP, FTP, etc.
|
Domain Name Services (DNS) |
Have configured systems as primary, secondary, and authoritative
Domain Name Servers for both Internet (external) and Intranet (internal)
networks.
|
Network Management |
For a midtown law firm, was responsible for the resolution of several
issues surrounding their combined DECnet, Novell, and TCP/IP network. Filed
paperwork required for the allocation and registration of a Class C IP number,
and paperwork required for the reservation of their domain name with the
Network Information Center.
|
Speaker |
Have spoken on Pathworks, DECnet, and related technical, operations,
and management issues at DECUS Symposia in the United States, Canada,
Switzerland, France, and Turkey. Presentations have included both one hour
sessions and full day seminars.
|
Author |
Have authored several articles on Pathworks, DECnet, and related
areas. Articles have been published by Digital Systems Journal,
Open Systems Today, Network Computing,
Digital News, and Hardcopy.
