  • Publication number: 20230396459
    Abstract: A method includes receiving, at a first edge node, an Internet Protocol (IP) multicast address of a first silent host node. The method further includes receiving, at a second edge node, an IP multicast address of a second silent host node. The IP multicast address of the first silent host node is equal to the IP multicast address of the second silent host node. The method further includes storing the IP multicast address of the first and second silent host node in a shared entry of a routing table. The method further includes receiving, at a third edge node, a packet from a third host node and determining that a destination address of the packet corresponds to the IP multicast address stored in the shared entry of the routing table. The method further includes sending the packet to both the first host node and the second host node.

  • Patent number: 11784970
    Abstract: The present disclosure is directed to systems and methods for first hop security in a multi-site and multi-vendor cloud. The method may include receiving, at a first hop security (FHS) device located within a defined security perimeter, a message from a first host; validating a security of the message; signing the message with a signature to prove validation of the message, the signature comprising at least a Crypto-ID Parameters Option (CIPO) and a Neighbor Discovery Protocol Signature Option (NDPSO); and transmitting the signed message to one or more network FHS devices within the security perimeter.
