Financial Telecommunications Projects
- Customer support with
computer service bureau, particularly for financial industry.
Customers included Canada Permanent
Trust.This included assisting
with installation of pilot locations and with development of initial
- NCP and VTAM
definitions for SNA based financial networks
- Lead programmer on
service to support SNA dependent logical unit devices, such as the 3270,
with independent logical unit switching across a packet switching
implementing an SNA System Services Control Point (SSCP) in a
microprocessor based telecommunications switch.
Initial support was for attachment using SDLC across leased
- Lead programmer on
project to support token-ring LAN attachment.
This delivered a service that permitted building a network
in which devices were attached either through SDLC, token-ring, or X.25
without regard to how the remote device or host with which they were
communicating was attached.In
particular remote devices attached across low-cost SDLC connections could
take advantage of a high-speed token-ring attachment at the host.
Such a nework could provide higher
availability than a conventional SDLC network because failures of
individual components along the network path were dealt with transparently.
Additional features included the
ability to transparently load balance access across multiple mainframes,
even at different locations.Two
years after we deployed this service the market for SDLC to token-ring
took off and our service was recognized as the “telecommunications hot
product of the year”.
- Project leader for
support of SNA host-to-host connectivity.
The lead customer on this project was the Federal Reserve Bank of
the US.This was originally
designed around PU4-PU4 connectivity, but the marketplace was changing so
fast that the project was re-vectored into two services:
- Basic SNA subarea node
to subarea node connectivity at the datalink level.
This supported SDLC, X.25, and
Token-Ring attachment in the same combinations as the earlier service for
dependent SNA.This was made more
complex because IBM, not anticipating a requirement for such
interconnection, used somewhat different protocols on the three
media.Therefore the service had
to translate between data idioms as the frames passed through the network.
- Type 2.1 Independent
Logical Unit session switching.
This service made every logical unit attached to the network appear
to be in the immediately adjacent node.
The network used an internal broadcast to locate the actual
attachment point of the destination logical unit.
Very high reliability was provided by
the underlying packet switched network, which would transparently recover
from failures of individual nodes or links.
A lead customer for this was Groupe Desjardins.
It was also sold to sparkasse
networks in Sweden, Norway, and Austria.
- Project leader
token-ring Brouter.In the early
1990’s many financial networks were adding LAN type applications to their
existing SNA based services.This
project added support for IP and Netware protocols on token-ring
attachments.This is called a
Brouter because while it did not implement all of the router protocols to
be called a Router, it did implement enough to effectively filter traffic
to eliminate broadcasts.Packets
were only forwarded into the network if the target network address was off
the local net.Advertisement
packets, which are sent to broadcast addresses, were recognized.
The first such packet was let though,
but subsequent repetitions were blocked, while the remote end took
responsibility for those repetitions.
For reliability the service permitted multiple instances to be
configured on each LAN segment, with load balancing.
The lead customer on this product was
- Architect on project
to migrate network of SWIFT (Society for Worldwide Inter-bank Financial
Transfers) from proprietary Burroughs implementation to X.25.
Used standard tools to formally
validate the protocol specification.
- Architect on project
to add support for data over voice service for point-of-sale
authorizations for Bell-South and Visa International.
This included verifying the multi-point
polled point-of-sale protocol specification.
- Architect on project
to support IBM Advanced Peer-to-Peer Networking (APPN) support.
Lead customer ABSA Bank (South Africa).
- Design and
implementation of remote computer labs for community college
- Managing all
Telecommunications services, including PBX, for community college
- NCP and VTAM
definitions in first large scale shared SNA network in the world.
- Network operations
- Development of a
support application to automate network operations.
This was required because we had one of
the largest and certainly most complex early SNA networks and IBM had not
yet delivered any automation tools.
IBM later delivered NetView product.
- Performance monitoring
tools to detect response time problems before the customer reported them.
- Network topology
design tool.Again because our
network was so large and complex we needed to automate the network
topology definition before IBM delivered tools to assist this.
- Project leader on
basic service definitions for new high performance product line (sold
under the product name Magellan Passport).
This project laid out the service and management structure
for the product.
Manager application.This tool
provided a consistent user-friendly method of logging on to the network,
hiding the complexity of the multiple applications deployed on the
network.The session manager was
capable of communicating with tens of thousands of users while maintaining
fast response.It provided
extensive on-line help to assist users in getting the best out of the
network, and delivered news on services delivered.
The session manager also secured the
network by ensuring that users could only log on to applications for which
they were authorized.It
streamlined access to individual applications by permitting the user to
select an individual transaction under an application server (such as IMS,
CICS, or TSO), rather than having to first log on to the server and then
select the transaction.This meant
the user did not have to be aware of the existence of these applications
servers as entities.In the case
where applications were distributed across multiple mainframes the session
manager also hid that from the user, seamlessly redirecting user requests
to whichever host was best suited at the moment to satisfying the
request.In particular this
included balancing TSO users across multiple hosts based upon current
load.The session manager also
simplified the administration of individual CICS and IMS based services by
enhancing them with the option to support dynamically created terminal
definitions.The single stage
logon and dynamic terminal definition features required installing user
exits in CICS and IMS.

support for deployment of Model 204 and S2000 database managers in service
- Development of small-scale
relational database for demonstration pilot of an office automation
product line.In the early 1980s
the only commercially available relational databases had a minimum license
fee of about $250K.In this
project we designed the office system with the assumption that it would
use a relational database to maintain central information, such as
information about users, however for the pilot we wished to demonstrate
this capability without investing in a full-fledged database package.
I provided a small package that
provided the minimum required functionality for deployment, including CICS
transactions for updating the database contents and definition.
