1. A computer-implemented method for exchanging network management messages between a network access device and a management server, the method comprising:

  • receiving, at the network access device, a user datagram protocol (UDP) packet from a client to be transmitted to the management server over Internet, the UDP packet including a management message to be sent to the management server, wherein the network access device is one of a plurality of network access devices managed by the management server over the Internet, wherein each of the network access devices represents one of a router, an access point, and a switch, wherein each of the network access devices is associated with a local area network (LAN) and provides access to the LAN for its client devices;

    determining, at the network access device, whether the management server is reachable using a UDP protocol;

    transmitting 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;

    if the management server is unreachable using the UDP protocol,extracting a UDP payload from the UDP packet,encapsulating the UDP payload within a hypertext transfer protocol (HTTP) POST request, the HTTP POST request including a predetermined universal resource locator (URL) associated with the management server, andtransmitting the HTTP POST request having the UDP payload encapsulated therein to the management server using a HTTP protocol over the Internet.
