Project Pathway utilizes the network infrastructure of public clouds to create auto-scale, software only, corporate WAN overlay


Project Pathway introduces a paradigm shift in the way corporate WANs are built and operated by utilizing distributed communication and computation resources of public clouds and providing WAN connectivity and security as "pay as you go" services. CBN creates a software, auto-scale, agile overlay network across public cloud vendors and world-wide regions, interconnecting data-centers, branches, mobile users, IoT and SaaS. It connects corporate entities to the nearest cloud regions using VPNs as well as SD-WAN.


Project Pathway utilizes continuous measurements across all regions and SaaS to provide an accurate and topical view of the underlying network performance properties. Using this information, Project Pathway optimizes traffic routing between corporate facilities, mobile, IoT clouds and SaaS, across the public-cloud network. It scales up resources in real time with traffic demand providing a limitless capacity for security and communication and eliminating the need for throttling and prioritizing traffic through congestion control mechanisms. Project Pathway also improves end-to-end performance by optimizing TCP rate control along the cloud path. We implemented a CBN Proof of Concept based on IPsec, Linux's router and a proprietary central controller.
