Abstract
The disclosure provides an approach for reliable and secure data delivery on a data plane of a network between virtual tunnel endpoints of hypervisors. The approach involves using the Bidirectional Forwarding Detection protocol to transport additional information without adding to network congestion. Data is added to periodic health-check packets and processed by the receiving side. The packets are further modified to set an echo bit and receive an acknowledgement of the packets' successful transmission to the destination side.
