Method for connecting and forwarding traffic through a multipath hub
The patent US12047244B2 outlines a method for efficiently forwarding traffic between edge devices located at different branch offices through a hub in a datacenter's hub cluster. The process begins with the first edge device sending a connection request to a hub, which is selected based on load assessments of the hubs within the cluster. The selection and connectivity data are communicated via a gateway, allowing the first edge device to establish a tunnel to the chosen hub. Traffic is then forwarded from the first branch office to the second branch office through this hub. The method also includes provisions for establishing a direct tunnel between the two edge devices after initial traffic forwarding, enhancing communication efficiency.
Additionally, the patent describes a non-transitory machine-readable medium that stores a program designed to execute the aforementioned traffic forwarding method. This program includes instructions for sending connection requests, receiving hub selections, and utilizing connectivity information to establish direct tunnels between edge devices. The gateway plays a crucial role in monitoring hub usage statistics, such as tunnel usage and processor load, to optimize hub selection. The patent emphasizes the adaptability of the system for enterprise datacenters, ensuring that traffic management is both effective and responsive to real-time conditions within the hub cluster.
