Company name: Founders hope "Bluewave" evokes the same feeling of tranquility you'd get from watching the ocean on a calm day.

How did the company start? CEO Kumar Sripadam and CTO Guna Ramireddy, engineers who worked together at IP equipment vendor Redback Networks, teamed in May 2001 to develop a product that delivers Layer 3 IP data in a meaningful way. Other products, they say, don't provide enough information about the network, where the problem resides and how that problem relates to applications.

Funding: Undisclosed amount of private funding.

CEO: Sripadam, who had been senior technical director for the engineering team that created Redback's first product.

Product: Infrastructure Analytics and Management System (INAMS) software.

Calming network and application performance storms
Why needlessly cobble together route, traffic flow and application performance information from disparate systems? That's the question Bluewave poses to enterprise network executives, offering them its flagship INAMS as an answer.

INAMS combines network topology information with IP traffic flow and routing data with detailed analysis of inter-router application traffic and real-time analysis of application packets, Sripadam says. Through this approach, Bluewave provides more application-specific data and more immediate analysis than competitors such as Ipsum Networks and Packet Design, he says. "We collect data on many different pieces of the network stack, and we can correlate that data in real time to, say, determine if a service degradation is due to a topology change," he says.

INAMS consists of two components. The first is INAMS Sensor, software that can be installed on a server, workstation or packaged with a proprietary appliance. The second is INAMS Console.

Sensors, which are distributed throughout a network, peer logically with routers. They watch traffic and routes, constantly updating a database, and can monitor routing protocols such as Open Shortest Path First, Border Gateway Protocol and Intermediate System-Intermediate System. The software can alert managers when thresholds are missed and create management events when network anomalies occur. Today, the product does not take automated corrective actions, but it will suggest potential fixes.

The INAMS Console runs on a Windows or Unix server and is the central management point for the Sensors. From the console, network managers can get a single view of routing and traffic analytics, and operators can replay routing and traffic events logged over time and correlate application performance problems with, for example, periods of network congestion. Network managers can access the INAMS Console via a secure Web interface.
