Claim 1:
2. A polymorphic network control method supporting terminal mobile access, which is implemented based on the polymorphic network control system supporting terminal mobile access according to claim 1, comprising:
step (1) a wireless access point (AP) releasing a channel of a wireless network based on wifi in an Institute of Electrical and Electronics Engineers (IEEE) 802.11 protocol during a mobile device accessing the link layer of the system, the mobile device scanning, identifying and connecting the channel of the wireless network corresponding to the AP based on the IEEE 802.11 protocol, and the global identity resolution service completes registering a mapping relationship between an identifier of the mobile device and the network address and starting a keep-alive mechanism between an access router and the mobile device;
step (2) introduction of the identifier and the network address enabling the identifier of the mobile device to be separated from a locator of the mobile device in the network, and separating identity and location enabling an identifier network to support the hybrid routing of the identity information and the location information, wherein a data message stores an identifier of a destination host, and a network address of the destination host with an optional field, and wherein a routing device of a network layer in a polymorphic network stores two kinds of forwarding tables, one is a mapping from the identifier to the network address, and the other is a mapping from the network address to a port number or a next hop address; and
step (3) in the polymorphic network, the chunk being transmitted to a destination node hop by hop in the network layer, and data being selectively stored in each hop temporarily, wherein each hop is reliably transmitted by a simple link layer data transmission protocol, and adopts two kinds of complementary group elements, a segmenter of an upstream node and an aggregator of a downstream node, and wherein the segmenter segments the data and transmits the data as chunks of a largest transmission unit, and the aggregator aggregates the chunks for routing.
