Talarian Buys WhiteBarn to Beef Up Multicast

LOS ALTOS, CALIF. (05/02/2000) - Talarian Corp. this week purchased WhiteBarn and its Pragmatic General Mutlicast (PGM) expertise in an effort to become the dominant player in the IP Multicast space.

PGM, a specification authored by WhiteBarn and Cisco, is designed to bring some level of reliability to IP Multicast technology. Standard Multicast protocols do not have any inherent reliability built in. The main benefit of Multicast is bandwidth savings and simultaneous delivery of content by using a single network stream to serve all clients.

Talarian had been working with the Reliable Multicast Transport Protocol 2 (RMTP 2) within its products, but it decided that PGM, a competing standard, was worth investing in as well.

"Anything that Cisco backs, you have to pay attention to," says Tom Laffey, founder and CTO of Talarian.

In addition to gaining more expertise in the area of reliable Multicast, Talarian also gains a development center near Chicago, where the competition for technical help is not as fierce as in Silicon Valley. From WhiteBarn's perspective, the company gained the sales and marketing help it needed to grow beyond a small, self-funded company, says Mark Mahowald, the company's founder.

Mahowald is now vice president of Talarian's Multicast and Network Technology division, which is essentially the WhiteBarn staff plus a few new additions.

The group will remain in Warrenville, Ill., and work with both PGM and RMTP 2.

The deal was a combination of stock and cash. No other terms were disclosed.
