Review of Information Technology Network Performance

The Postal Service operates and maintains one of the world’s largest computer networks, linking more than 31,000 retail locations and making communication possible among hundreds of thousands of employees. The Postal Service processes more than 146 billion mailpieces annually and delivers nearly half of the world’s mail. To do this, the Postal Service relies on about 86,000 network devices that support the Information Technology (IT) and mail processing infrastructures. Our objective was to determine if the U.S. Postal Service’s network performance is optimized to support infrastructure demands and ensure system availability.
