Abstract

A network access device (NAD) receives a UDP packet from a client to be transmitted to a management server over Internet, the UDP packet including a management message. The NAD is one of NADs managed by the management server. The NAD determines whether the management server is reachable using a UDP protocol. The NAD transmits the UDP packet to the management server using the UDP protocol over the Internet if it is determined that the management server is reachable using the UDP protocol. Otherwise, the NAD extracts a UDP payload from the UDP packet, encapsulates the UDP payload within an HTTP POST request, and transmits the HTTP POST request having the UDP payload encapsulated therein to the management server using a HTTP protocol over the Internet.
