Publicly held Micromuse develops network management software that helps large organisations control their network infrastructure. The company reported revenues of $161m and a net loss of $3.8m in its most recent fiscal year.
IBM is betting that the rise of new data services, including VoIP and internet-based audio and video, will increase demand for such services.
"Today's networks are no longer just pipelines of data; customers are incorporating data, voice and video into their business operations at an astounding pace," said Al Zollar, general manager for Tivoli software at IBM.
"The addition of new capabilities raises the complexity of today's networks, which require real-time network and service management."
The Micromuse products will be integrated into IBM's Tivoli suite of system management software.
More than 1,800 organisations use Micromuse's technology, and the two vendors have 500 joint customers.
