MCI is a leading long distance telecommunications and networking company that for a period of time was also know as WorldCom and is now a subsidiary of Verizon Communications.

MCI World Engineering Headquarters 2400 Glenville Richardson, TX  75082

• Developing MCI's 1st and 2nd generation Network Engineering Software Robotic systems and its companion intranet information and control system.

• Developing and assisting with other smaller projects.

• Consulting, advising, conducting classes, and training developers in:
  • Java and C++
  • Mission critical systems design
  • Networking architectures and systems
  • Visual C++ programming
  • Java IDE
  • Web systems design, development, and deployment
  • Transitioning from OS/2 to Windows Server

• Architecture, development, and deployment of an intranet information and control system including custom native servers and Java clients.
  The Java / Client server is how MCI Provisions its global network. This intranet website experiences very heavily traffic. The web based system provides platform-independent network engineering tools that operate with the DPC robots and the Next Generation Robotic system CHAMPS. The Java applets contain both user interface and front end processing logic. The applets remotely control the robots, engineering work submission, multi-level report capabilities, and system administration, all via the MCI intranet. This Java UI is the forerunner of an entirely new way MCI engineers will do their job. At the first demonstration of this product, Bohacz received a standing ovation and the "I am blown away." pronouncement from one of the most senior members of MCI Technical Management.

• Architecture and development of the next-generation network engineering robotics systems CHAMPS. This Windows Server and Java based system is 10 times more powerful and supports 100 times more concurrency than the DPC Robots. This system is online operating in parallel with the 1st generation system and includes:
  • Smart agent robot architecture
  • MCI's first use of signed Java applets which break out of the sandbox
  • Java client / server N-Tier: web based admin, user reporting, and work submission
  • N-Tier architecture
    • Smart agent robots contain the systems logic which engineers the frame relay and private line network circuits.
    • Java client GUIs provide control, monitoring, and job submission.
    • Custom server-side subsystems collect jobs from Java clients and mainframe work queues and submit the jobs to the smart agents.
  • Full network interconnectivity between agent subsystems running on hardware anywhere in the world.
  • Dynamic and static 3-dimensional throughput scaling: control of concurrency spanning multiple processors and machines as well as the depth of concurrency of individual agents
  • Software / Hardware is fault tolerant.
  • Oracle DB server

• Architecture and development of the first generation mission-critical software-robot DPC, a fully autonomous engineering system that provisions the hardware infrastructure comprising the MCI Telecom Global Network. When a business uses the internet, makes a VISA transaction, or communicates between branch offices, chances are good that the DPC Robots have engineered the network routes used. When first rolled out in 1995, banners were hung at MCI World Engineering Headquarters announcing the arrival of the DPC system.

  The DPC robot system is written in C / C++ and Java code. It is a massively parallel system: 14 machines run in parallel, each with over 24 threads running in parallel, distributed across three processes.

  • N-Tier Architecture
  • DPC robots contain the systems logic to provision network circuits.
  • Java client GUIs provide control, monitoring, and job submission.
  • Job server / "work feeder" collects jobs from Java clients, acts as their server, and collects jobs from mainframe work queues filled by other GUIs. These jobs are then submitted to the DPC Robots.

• Architected and developed two stand-alone engineering products, MeccaSim and NSS Monitor:
  • MeccaSim, an OS/2 PM product, is a host simulator that automatically tee-connects into an 3270 session (CM/2) and replicates complex query sessions. MeccaSim is used for new systems development and regression testing.
  • NSS Monitor, an OS/2 PM product, is a TCP/IP network traffic monitor and simulator for newly deployed host / server systems.

• Architected and developed subsystems for IPWS Telecom Network Engineering Workstation which aided engineering in provisioning private line circuitry. This engineering tool was superceded by the DPC Engineering Robots.
