Abstract:
1. A method for routing data in a wireless mesh network, the method comprising: receiving a first packet at a first wireless mesh access point (AP), the first wireless mesh AP being one of a plurality wireless mesh APs of the wireless mesh network, wherein each of the wireless mesh APs includes a mesh link interface to communicate with each other and a local link interface to communicate with a local client of each wireless mesh AP; determining an interface identifier (ID) based on a destination media access control (MAC) address of the first packet; transmitting the first packet via the local link interface to a local client if the first packet is intended to the local client based on the interface ID; determining an AP source MAC address and an AP destination MAC address based on the interface ID by performing a lookup operation in an interface mapping table, the interface mapping table including a plurality entries, each entry including an interface ID associated with an AP source MAC address of an egress mesh link interface corresponding to the interface ID and an AP destination MAC address of an ingress mesh link interface of a second wireless mesh AP; and transmitting at least a payload of the first packet to the second wireless mesh AP via the mesh link interface using a secure tunnel established between the first and second wireless mesh APs based on the AP source MAC address and the AP destination MAC address obtained from the interface mapping table, if the first packet is not intended to the local client of the first wireless mesh AP, wherein at least the payload of the first packet is routed using a layer-
