McObject Enhances Fault Tolerance in Next-Generation Emergency Radio

3/17/2004 - EFJ, Inc. (NASDAQ: EFJI), an industry-leading provider of wireless communications systems for homeland security and public safety agencies, announced that its EFJohnson subsidiary will integrate McObject’s eXtremeDBTM High Availability (HA) in-memory embedded database as part of upgrades to enhance fault-tolerance in its NetelligentTM Infrastructure Systems Project 25 Conventional two-way radio infrastructure for first responders.

eXtremeDB HA will help the system become more fail-safe by enabling distribution (replication) of central database information, so each major system element has its own copy and is not dependent on links back to a single database server. Multiple, synchronized copies of McObject’s embedded database will reside within embedded controllers in Netelligent base station repeaters and other key devices.

“eXtremeDB’s ultra-small footprint (less than 110K code size) allows its use within Netelligent hardware where RAM and CPU constraints ruled out the use of other embedded databases,” according to Michael E. Jalbert, chairman and chief executive officer of EFJ, Inc. “eXtremeDB also stands out in terms of performance. Its streamlined design and in-memory deployment meet the near-zero-latency demands of real-time radio communications,” Jalbert said.

A critical requirement for a two-way radio system designed for public safety is reliability. Using a rugged, time-cognizant, two-phase commit protocol, eXtremeDB HA ensures that changes to a master database and identical standby databases succeed or fail together, enabling deployment of multiple fully synchronized eXtremeDB databases within the same hardware device or across multiple, widely-distributed systems. eXtremeDB’s two-phase commit protocol facilitates instantaneous fail-over, with zero replication-induced latency.

Project 25 (P25) is the Telecommunications Industry Association’s (TIA) standard for digital 2-way radio technology. P25 was originally created by the Association of Public Safety Communications Officials International (APCO) in cooperation with the National Association of State Telecommunications Directors (NASTD) and the U.S. government to insure interoperability between Federal, State, and local public safety agencies.

Jalbert said, “Increasingly, governments and other agencies demand P25 compatibility. EF Johnson’s Netelligent Infrastructure Systems targets the communications needs of public safety users at Federal and state/local levels, providing a secure, reliable and scalable Project 25 solution to support their activities.”

“EF Johnson’s Netelligent Infrastructure Systems fulfill the all-important communications task of knitting together federal, state and local agencies’ responses to emergencies. We are pleased by EF Johnson’s vote of confidence in choosing the eXtremeDB in-memory embedded database to enhance the Netelligent system’s fault-tolerance,” said Steve Graves, McObject co-founder and CEO.

“In emergencies, diverse agencies must be able to cooperate, and their communications systems must be reliable. EF Johnson’s leadership in Project 25-compliant technology, embodied in the Netelligent Infrastructure System, enhances police, fire, federal disaster and other forces’ ability to work together. Within EFJohnson products, eXtremeDB will contribute to reliability by allowing distribution and synchronization of system data stores, avoiding over-reliance on a single data management node,” Jalbert said.
