Method for efficient wan traffic transmission using edge devices
The patent US12040982B2 describes an edge network device designed to optimize the transmission of network traffic across a wide area network (WAN). The device operates within a first site that includes a second edge network device, both connected via a local area network (LAN). The primary function of the first edge network device is to receive network traffic and determine the most efficient service provider connection for transmission. This determination is based on a comparison of path characteristics—such as latency and bandwidth—of the first and second service provider connections, as well as the classification of the network traffic (e.g., voice or video). If the second service provider connection is deemed more suitable, the device forwards the traffic to the second edge network device through a local tunnel over the LAN, enabling the second device to transmit the traffic to a designated second site.
Additionally, the patent outlines methods for sharing path characteristics between the two edge devices and periodically updating these characteristics to ensure optimal performance. The first edge network device can store path characteristics for both service provider connections and make informed decisions based on real-time data. The methods also include encapsulating network traffic with specific headers to facilitate transmission through the local tunnel. This innovative approach aims to enhance the efficiency of data transmission across the WAN by leveraging the capabilities of multiple service provider connections, ultimately improving the quality of service for various types of network traffic.
