Abstract: Network link redundancy may be provided. A node comprising a virtualization of a network topology comprising a plurality of devices may be provided. Next, the node may be provided with at least two ports. Each of the at least two ports may respectively comprise an inside facing portion that uses a first protocol and an outside facing portion that uses a second protocol. The node may operate using the first protocol. A behavioral mode of the at least two ports may be controlled and the behavioral mode of the at least two ports may be communicated to at least one other node outside the node.

Abstract: In accordance with various implementations, a method is performed at a source node of a fabric network coupled to a plurality of hosts respectively associated with a plurality of group identifiers. The method includes generating a source public key based on a source private key, a source group identifier of the plurality of group identifiers, and a destination group identifier of the plurality of group identifiers. The method includes sending, from the source node coupled to at least one host associated with the source group identifier to a destination node coupled to at least one host associated with the destination group identifier, the source public key. The method includes receiving, at the source node from the destination node, a destination public key based on a destination private key, the source group identifier, and the destination group identifier. The method further includes generating a shared secret based on the destination public key and the source private key.
