Dynamic routing of ipv6 packets in wireless mesh network
A recently granted patent (Publication Number: US11849383B2) discloses a method for routing packets in a data network that includes a wireless mesh network and a controller. The method involves using a monitor function and a route table manager to generate a route table that relates IPv6 addresses to nodes of the mesh network via point of presence (POP) nodes. The controller communicates management traffic with the nodes using IPv6 protocol and an OSI Layer 2 network to direct the traffic between the controller and nodes via the POP nodes based on the route table. The method dynamically amends the route table to ensure reachability of POP nodes and efficient packet routing within the network.
Furthermore, the patent describes a system that implements the method, comprising a wireless mesh network, a controller, a monitor function, and a route table manager. The system is configured to manage the wireless mesh network efficiently by generating a route table, determining reachability of POP nodes, and directing IPv6 management traffic without the need for an external OSI Layer 3 router. Each zone in the wireless mesh network corresponds to an IPv6 subnet, with POP nodes serving as gateways. The system dynamically adjusts the route table to maintain connectivity and selects routes based on the longest prefix match. The controller, known as an End to End (E2E) controller, centrally manages the network and communicates with nodes using IPv6 for various management functions, including configuration data, link setup control, and performance data collection, enhancing the overall network performance and reliability.
