Multi-optical port communication method, device, device and storage medium

Abstract

The invention discloses a multi-optical port communication method, device, device and storage medium, wherein the method includes: pre-configuring the Vlan IDs of several optical ports; The Vlan ID of the interface is used to transmit the data packet to the corresponding application layer. Through the Vlan ID corresponding to the optical port, the data packet can be distinguished from the incoming data packets of other optical ports. Since the frequency bands of the signals transmitted by different optical ports are different, the incoming data packets of different optical ports need to carry out information The interactive application layer will also be different, and the data packet can be transmitted to the application layer corresponding to the optical port for information interaction through the unique Vlan ID; the method provided by the present invention realizes multiple For optical port communication, there is no need to configure or modify any peer or next-level unit / device, and the MAC address of any unit / device is not changed during the entire transmission process of the data packet, avoiding the problem of MAC address conflicts.

Description

technical field [0001] The present invention relates to the field of optical fiber communication, more specifically, to a multi-optical port communication method, device, equipment and storage medium. Background technique [0002] In the communication system, the digital radio remote system GRRU (GSM Digital Remote RF Units) uses software radio technology to digitize the signal of the GSM Um port, transmits it to the remote end through optical fiber, and uses the remote radio frequency unit to regenerate and amplify the base station signal. Remote coverage wireless network coverage equipment. GRRU is a product that successfully applies RRU technology widely used in 3G to GSM system, and provides an effective solution for network coverage engineering and optimization. Among them, the digital remote radio system includes a digital access unit DRAU and a digital remote unit DRU. The digital access unit DRAU directly couples the base station signal, and transmits the signal to ...

Problems solved by technology

However, the premise that this method is applicable to the upper-level unit is that the lower-level unit connected to it is a device for transmission through a single optical port, and this optical port only corresponds to one of the fixed optical ports transmitted to the upper-level unit. It is only possible to change the MAC address of the next-level unit to distinguish the incoming information from each optical port, but the next-level unit is also a device for multi-optical port transmission, and the multiple optical ports of the next-level unit do not only correspond to transmission To one of the fixed optical ports of the upper-level unit, but to multiple optical ports of the upper-level unit, in this case, the upper-level unit cannot achieve multiple Optical port transmission; secondly, changing the MAC address to identify the optical port is likely to cause MAC address conflicts when multiple units are cascaded; finally, although this improved method has realized the multi-optical port transmission of the upper unit, it involves For the configuration and improvement of the lower-level unit, if the upper-level unit needs to add more connected lower-level units, it is necessary to repeat the configuration of more lower-level units. It can be seen that this improvement method is not perfect and not practical
