Embodiment Construction
[0048] In order to simplify the routing and forwarding process, the present invention proposes an SDN-based Ethernet IP packet encapsulation method and network isolation and DHCP implementation method. This solution does not modify this layer, but only limits the frame addressing and identification functions Remove, for the server directly judges whether the IP packet is the IP packet of the local machine after receiving the packet, if not, then directly performs routing, and if so, then enters the protocol stack for processing. The switch analyzes the packet starting from the IP header, and then forwards it according to the matching flow label item; if no flow label item is matched, it will process it according to the corresponding table miss configuration. The program has the following characteristics:
[0049] 1. After canceling the fields such as MAC and VID, the content of the data segment can be added to the message of the same length, which increases the proportion of t...
