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...

Abstract

The present invention proposes an SDN-based Ethernet IP packet encapsulation method and network isolation and DHCP implementation method, which solves the above-mentioned technical problems such as complex forwarding process and reduced transmission efficiency caused by packet layer 2 header encapsulation. Step 1, the physical layer of the device obtains physical signals from the transmission medium according to the frame gap and the guide frame, and converts the physical signals into bits, and sends them to the data link layer; Step 2, the data link layer performs MAC address identification and addressing; Step 3, analyze the protocol stack to identify the message; Step 4, transfer the route to the data link layer to perform other processing procedures except Ethernet encapsulation and MAC addressing, according to The message header format is passed to the physical layer for processing; step 5, the physical layer converts the bits of the message data frame into photoelectric signals according to the original method and forwards them.

Description

technical field [0001] The invention relates to an SDN-based Ethernet IP message encapsulation method and a network isolation and DHCP implementation method, belonging to the field of Ethernet message encapsulation. Background technique [0002] The current Ethernet has been relatively maturely applied in the actual network. Due to the historical development of the network, the current Ethernet message has two addresses, one is the MAC address and the other is the IP address, and it is forwarded on the second layer. The IP address does not work during the process. At the same time, during the three-layer forwarding process, the MAC address of the packet header is constantly changed. Two network devices that are not in the same LAN and need to communicate do not need to obtain the MAC of the intermediate network device. address. Moreover, in the last hop of the message, it is also necessary to complete the conversion of the IP and MAC mapping of the message, which complicate...
