A communication method, device and system

Abstract

Embodiments of the present invention provide a communication method, device, and system. The communication method includes receiving a message, encapsulating all or part of the message in an Ethernet operation, management, and maintenance message, and then according to the port that receives the message and the Correspondingly maintain the corresponding relationship of the endpoints of the entity group, and send the encapsulated message to the device where the entity group is located. The communication method, device and system provided by the embodiments of the present invention use port mapping and message encapsulation methods to implement IP address-based communication and management for devices without an IP address.

Description

Technical field [0001] The present invention relates to the field of optical communication technology, in particular to a communication method, device and system. Background technique [0002] In the existing network architecture, network connection, information interaction, and network monitoring and management largely rely on the Internet Protocol (IP) address of the interconnection between the networks of the devices. Users use the server in the network to access the network based on the IP address assigned to them by the IP protocol. Different users use their own IP addresses for information interaction, and the network administrator uses the IP address to monitor and manage the network. [0003] However, with the need for flat management, the network devices connected to the access devices in the network are becoming more and more compact, and the number is increasing. If each network device is assigned an IP address, it will result in a limited IP address. resource crisis. ...

AI Technical Summary

Problems solved by technology

However, most of the existing network connections, information interactions, and network monitoring and management are based on IP addresses, which also makes it difficult for network devices without IP addresses connected to access devices in the network to achieve communication based on IP addresses.
