Method to route traffic through sd-wan with flow identifiers
A recently granted patent (Publication Number: US11956145B1) outlines a method for routing traffic through a software-defined wide area network (SD-WAN) between two hubs. The method involves receiving a sequence of packets from a client at the first hub, establishing a secure tunnel between the hubs, assigning flow identifiers to the packets, encapsulating start packets in wrappers with flow identifiers, and sending them through the secure tunnel. In case of errors, such as session aging or hub restart, the method involves re-establishing the secure tunnel, assigning new flow identifiers, and sending the packets again. Additionally, the method includes converting packet headers to reduce bytes and sending them through the secure tunnel.
The patent also covers the configuration of error messages, error codes, and the use of Internet Control Message Protocol (ICMP) messages. It further details the conversion of packet headers to metadata supplements, the removal of header fields, and the encapsulation of reduced packets with flow identifiers. The patent extends to a non-transitory computer-readable storage medium containing program instructions for executing the method and a network node with a processor and memory configured to perform the operations outlined in the patent. The network node is designed to receive packets, establish secure tunnels, assign flow identifiers, encapsulate packets, handle error messages, and convert packet headers for efficient routing through the secure tunnel. The patent emphasizes the importance of maintaining flow consistency and secure communication between hubs in a software-defined wide area network.
