CACE's traffic recording, analysis and inspection platform should help customers troubleshoot network and application performance issues, Riverbed says.
Dependence on the WAN in cloud computing is increasing the need for visibility of all network segments in order to find where bottlenecks lie and what factors are impairing performance, the company says.
CACE Technologies' Shark Appliance and Pilot Console supports management of network performance by discovering applications on networks, monitoring their performance and recording traffic for analysis.
This is Riverbed's second acquisition in this area, having bought Mazu Networks in 2009. Riverbed's Cascade line is based on Mazu technology.
CACE also sponsors Wireshark and WinPcap open source packet analysis tools, and Riverbed says it will keep Wireshark open.
