Claim 2:
3. The polymorphic network control method supporting terminal mobile access according to claim 2, wherein the step (1) comprises:
sub-step (1.1) the access router maintaining information of a network host that has accessed the router, and periodically broadcasting a probing packet for the network host;
sub-step (1.2) when accessing a network, the network host receiving the network host probing packet broadcast by the access router and replying with a probe return packet;
sub-step (1.3) after receiving the replied probe return packet, the access router inquiring whether the host has been registered, in case the host has not been registered, updating registered network information that is locally maintained, constructing a registration package and uploading the registration package to a global identity resolution service, and executing the step (1.4), in case the host has already been registered, executing the step (1.5) without constructing a registration package;
sub-step (1.4) the global identity resolution service receiving the registration package, creating a mapping of the identifier to the network address and completing global identity registration;
sub-step (1.5) the access router continuing to periodically broadcast the probing packet of the network host and receiving the probe return packet, when the network host is disconnected from the access router and the access router fails to receive the probe return packet of the host over time, the router deleting the network host information that is locally maintained and constructing a logout packet to be uploaded to the global identity resolution service; and
sub-step (1.6) the global identity resolution service receiving the logout package and completing a logout operation.
