Data Communications and Operating Systems

Network Management for Xyplex, a communications equipment vendor. Designed and implemented an SNMP (Simple Network Management Protocol) agent and numerous MIBs (Management Information Bases) for several releases of their bridge/router and intelligent hub product lines.

Refinement and implementation of a distributed routing protocol for data communication networks that achieves minimum delay and takes topological changes into consideration. (Now, this was fun! This work was done when Marty was an employee of Interactive Data Corporation, and remains one of his favorite projects.)

There's lots more communications work: packet networks, an early micro-network protocol that provided and error-free and flow-controlled channel for dial-up connections (before modems did this work), network access protocols, network management ...

Also as an Interactive employee, Marty worked on a modified version of IBM's VM/CMS Operating System. He delved into the virtual memory, scheduling, dispatching, I/O and other subsystems. Water-cooled mainframes, banks of disk drives each the size of a washing machine, core memory. This was fun, too.
