METHOD FOR TRANSMITTING AN ALERT USING A NETWORK VIRTUALIZATION USING GENERIC ROUTING ENCAPSULATION (NVGRE) TUNNELING MECHANISM

摘要

A data packet comprising a header, the header having a format associated with a Network Virtualization Using Generic Routing Encapsulation (NVGRE) technology is generated at an originating tunnel end point device in a network. A predetermined bit in a reserved portion of the header is set to a predetermined value. In one embodiment, the reserved portion comprises a Reserved0 portion of the data packet. The data packet is then transmitted.
