TCS Issued Patent for Optimizing Data Transmissions

ANNAPOLIS, MD (NASDAQ: TSYS), a leading provider of mission-critical wireless communications, today announced the U.S. Patent and Trademark Office has issued patent number 7,353,289 for "System For An Open Architecture Development Platform With Centralized Synchronization." The patent describes a method and apparatus that optimizes data transmission between data clients and application servers, including mobile clients and those using TCP/IP network protocols.

This TCS invention determines the most efficient way to transfer data based on the size of the data payload and the characteristics of the network protocols. Data payloads can be combined or divided to fit into a maximum transmission unit (MTU), determined by the size of the payload to be transmitted. This can be used to provide higher, more efficient, and ultimately more cost-effective data throughputs for fixed and wireless data transmission applications.

"Optimizing the data transmission of fixed and mobile applications allows an operator to achieve higher throughput rates and enables a better user experience," said Drew Morin, Senior Vice President and Chief Technical Officer for TCS. "By packet stuffing the data packets, TCS' invention reduces the transmission overhead and increases the data throughput."

The TCS patent portfolio contains 58 patents and over 190 patent applications in the U.S. and abroad.

About The Invention

The "System For An Open Architecture Development Platform With Centralized Synchronization" patent provides a method and an apparatus for determining the maximum transmission packet that can be sent utilizing network protocols such as Transmission Control Protocol and the Internet Protocol (TCP/IP). Data payloads can be combined into the maximum allowable transmission packet using partial portions of a next payload.
