Cisco has agreed to pay $9 million to acquire the stock it doesn’t already own in Parc Technologies of London, UK.

Parc, who is a spin-off of Imperial College, University of London, is a developer of software for network traffic engineering and routing optimization.

According to Cisco, Parc’s route server algorithms can be used to “break up network routing problems” related to quality of service constraints.

Reuters reported that Cisco already owned 10 percent of Parc.
