As most of the technology focused world watches SD-WAN’s meteoric market rise, it is difficult to say people are surprised. This networking “golden child” is transforming architecture to improve service QoS, connect disparate branches and offer a reliable, pocket friendly and user-friendly path to cloud migration. And, recently FatPipe Networks took a pretty productive trip to the United States Patent and Trademark Office Patent Court.


The United States Patent and Trademark Office Patent Court upheld FatPipe’s claim for U.S. Patent No. 6,775,235 for load balancing over disparate networks. In specific, the patent illustrates a means for communicating using multiple disparate networks in parallel, which enables load balancing and failover of session flows and re-directing packets over multiple networks.

The claim is as follows:

A method for combining connections for access to parallel networks, the method comprising the steps of: sending a packet to a site interface of a controller, the controller comprising the site interface which receives packets, at least two network interfaces to parallel networks, and a packet path selector which selects between the network interfaces on a per-session basis to promote load-balancing; and forwarding the packet-through the network interface selected by packet path selector; wherein the step of sending a packet to the controller site interface is repeated as multiple packets are sent, and the controller sends different packets of a given message to different parallel networks.

"This is an important step in establishing the strength of this claim, elevating it to a super claim status. Having gone through the most rigorous evaluation, we now have the ability to protect the company's invention on WAN load balancing for VoIP, VPN and data traffic for corporate networks. Along with other FatPipe Networks' patents, this claim ensures that VoIP, Video, VPN and all data traffic can be load balanced and failed over without dropping sessions providing a superior SD-WAN product for customers. The benefits to customers are huge," said Dr. Ragula Bhaskar, CEO, FatPipe Networks.

FatPipe founders Dr. Ragula Bhaskar and Sanchaita Datta share more than 10 patents and over 180 technological claims involving SD-WAN and hybrid WAN technology.

The era of software-defined solutions driving enterprises toward the cloud and digital transformation is at hand. Ready for the revolution?
