On Thursday, Cisco Systems (CSCO -0.52%) announced its intent to purchase privately held "network planning, design and traffic managements solutions provider" Cariden Technologies, for a total purchase price of $141 million. This is Cisco's third major acquisition in November, following on the heels of the company's $125 million purchase of software designer Cloupia, and its $1.2 billion acquisition of Meraki, and brings the company's investment in "cloud computing" acquisitions to nearly $1.5 billion for the month.

In a statement, Cisco noted that Cariden's technology will help its service provider customers "to improve both the programmability of their networks and the utilization of existing network assets across the IP and optical transport layers."

Upon completion in Cisco's fiscal Q2 2013 ending in January, Cisco intends to integrate Cariden into its Service Provider Networking Group.

Shares of Cisco are up 1% on the news.
