SAN MATEO (04/25/2000) - Looking to provide infrastructure for e-commerce, transactional, and trading-floor applications, Talarian Corp. has acquired multicasting technology provider WhiteBarn Inc. and plans to integrate WhiteBarn's implementation of the Pragmatic General Multicast (PGM) protocol with Talarian's SmartSockets message-oriented middlewareThe acquisition for an undisclosed sum will enable Talarian to provide customers with more choices when they build real-time infrastructures, said Tom Laffey, co-founder and CTO at Talarian. The messaging and multicasting vendor can now offer WhiteBarn's PGM implementation as well as Talarian's own RMTP-II (reliable multicast transport protocol) multicasting, Laffey said. The PGM implementation will also be integrated with the SmartSockets middleware.
WhiteBarn also offers products for multicast file transfers. Multicasting provides a mechanism for wide-scale distribution of messages to multiple parties.
"We're seeing companies push the limits of scalability," Laffey said.
In particular, many e-commerce businesses are finding that with increased demand comes increased volume, Laffey said. Also, some of Talarian's major clients in the securities-trading industry are seeing a rise in volume because of market conditions, more day trading activity, and the move toward a decimal-based pricing system for stock trading, he said.
For real-time, publish/subscribe infrastructure needs, companies are likely to use a mix of real-time infrastructure technologies such as TCP/IP-based links for wide-area access and multicasting for local-area computing, Laffey said.
This approach will serve a variety of vertical needs, including the securities trading floors of major banks and trading companies and the activities of e-commerce businesses, Laffey said.
The Talarian offerings are aimed at those businesses -- many in the financial services and telecommunications industries -- that have high-speed, high-volume needs, said Karen Boucher, an analyst at The Standish Group, in Dennis, Massachusetts. This is lower-level technology that will begin to make sense for those users who are finding "that they can handle the demand just with TCP" -- the upper stack of the TCP/IP protocol set -- and must turn to multicasting, Boucher said.
The integration effort should be complete by the end of the year, said Mark Mahowald, the former president of WhiteBarn. Mahowald has joined Talarian as vice president of multicast and networking technologies.
The WhiteBarn PGM technology is also slated to be integrated with Novell Directory Services (NDS), Laffey said. Since January, Novell and Talarian have been collaborating on technology, and last month Talarian was able to demonstrate the integration of Talarian's SmartSockets with NDS.
