"Postal Service information technology officials have upgraded the 15-year-old, mainframe-based system to handle more transactions and lower the cost of operating the system.
"The work to upgrade PTS is part of a larger plan to standardize on the open-source and less expensive Linux operating system, said John Byrne, manager of application development and head of USPS’ Integrated Business Solutions Centers.
"The service is moving 1,300 Sun Solaris midrange servers to a Hewlett-Packard Linux environment. USPS is using Novell’s SUSE Linux on the mainframe and distributed computing platforms to forge greater interoperability between the two environments, Byrne said."
