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

Abstract

The invention discloses a multi-optical-port communication method, device and equipment, and a storage medium. The method comprises the steps of pre-configuring Vlan IDs of a plurality of optical ports; and when a data packet transmitted from a certain optical port is obtained, transmitting the data packet to a corresponding application layer according to the Vlan ID corresponding to the optical port. Through the identifier Vlan ID corresponding to the optical port, the data packet can be different from data packets transmitted from other optical ports, and because the frequency bands of signals transmitted from different optical ports are different, the application layers of the data packets transmitted from different optical ports needing information interaction are different. The data packet can be transmitted to an application layer corresponding to the optical port for information interaction through the unique Vlan ID. According to the method provided by the invention, multi-optical-port communication is realized through the mapping relationship between the pre-configured Vlan ID and the optical ports, any opposite end or next-level unit / equipment does not need to be configured or modified, and the MAC address of any unit / equipment is not changed in the whole transmission process of the data packet, so that the problem of MAC address conflict is avoided.

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
