Software-based WAN optimization is getting so popular that even the hardware companies are getting into the act.
Expand Networks is buying its way into the technology with the purchase of British firm NetPriva, developer of a unique socket-level approach that is said to improve traffic visibility within the client operating system. Expand hopes to gain new levels of QoS assurance, application control, traffic-shaping and overall management of the WAN environment.
NetPriva is housed aboard the remote PC, providing a "granular, portable and interoperable" environment for both fixed and mobile Virtual Private Networks (VPNs).
The system will be integrated into Expand's WAN Optimization Controller (WOC) appliances and SoftWOC clients as the company moves its architecture from traditional hub-and-spoke designs to more interactive mesh infrastructures.
