Abstract
In this invention we disclose methods for incorporating a security gateway within a wireless mesh network. In one embodiment, the wireless mesh network is a heterogeneous mesh network. In one embodiment, a gateway node, which is part of the wireless mesh network, requests a connection to the core network through a security gateway. The security gateway responds by creating an IPSec tunnel and a GRE tunnel within the IPSec tunnel from itself to the gateway node. Once the gateway node is communicatively coupled to the security gateway via secure tunneling, the gateway node sends a mesh routing protocol to the security gateway.
Claims16
A method of incorporating a security gateway within a mesh network comprising:
- receiving at a security gateway a request to initiate creation of an internet protocol (IP) security tunnel from the security gateway to a gateway node, the gateway node being a mesh node of a mesh network;
- creating the IP security tunnel from the security gateway to the gateway node;
- creating a generic routing encapsulation (GRE) Layer 2 tunnel inside of the IP security tunnel;
- requesting at the security gateway an IP-protocol mesh routing table from the gateway node;
- and
- receiving at the security gateway the IP-protocol mesh routing table from the gateway node,
- wherein the IP-protocol mesh routing table includes a route to a second non-gateway mesh node via the gateway node.
A non-transitory computer readable storage medium, storing thereon a computer program comprising instructions that, when executed by a computer system, cause the computer system to perform operations comprising:
- receiving at a security gateway a request to initiate creation of an internet protocol (IP) security tunnel from the security gateway to a gateway node, the gateway node being a mesh node of a mesh network;
- creating the IP security tunnel from the security gateway to the gateway node;
- creating a generic routing encapsulation (GRE) Layer 2 tunnel inside of the IP security tunnel;
- requesting at the security gateway an IP-protocol mesh routing table from the gateway node;
- and
- receiving at the security gateway the IP-protocol mesh routing table from the gateway node,
- wherein the IP-protocol mesh routing table includes a route to a second non-gateway mesh node via the gateway node.
