Abstract
A method for implementing multicast data exchange over a partitioned network having an encrypted domain with HAIPE devices at the edges consists of proxies running at an ingress edge and at egress edges of the encrypted domain. The proxies at the ingress edge device modify the multicast data packet to replace the destination address with the address of a proxy running on an egress edge device, such that the encrypted domain routes the packet directly to the proxy at the egress edge device without processing it as a multicast data packet. At the egress edge devices, the proxies restore the original address and send the multicast packets to the appropriate destinations.
