The US networking giant will pay $9m (£4.86m) in cash for all outstanding shares of Parc it does not already own.
A private company, Parc is a spin-off from an algorithm research centre at Imperial College. Its route server algorithms break up complex network routing problems.
Cisco plans to use the algorithms first in its Multiprotocol Label Switching (MPLS) TE product to help service providers improve network usage. The company also plans to incorporate Parc's Route Server software into its MPLS Management product portfolio and make it available as part of its IP Solutions Center.
The past few weeks have also seen Cisco snap up router maker Procket Networks and backup software provider Actona Technologies.
