Example Embodiment

[0037] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0038] See figure 1 As shown, the embodiment of the present invention provides a two-way communication system based on the MSA protocol, which is used to connect upper-layer devices and lower-layer devices. The two-way communication system includes dual-port RAM, upper-layer ring buffer management components, and lower-layer ring buffer management Parts, where:

[0039] Dual-port RAM includes an upstream ring buffer area and a downstream ring buffer area; the upstream ring buffer area is used to buffer the data packets written by the lower device through the lower end ring buffer area management component and for the upper end ring buffer area management device to read the data; The ring buffer is used to buffer the data packets written by the upper-level device through the upper-level ring buffer management component and for the lower-level end ring buffer man...

Abstract

The invention discloses a bidirectional communication system based on an MSA protocol, and relates to the technical field of optical communication. The system is used to connect upper equipment and lower equipment to realize the data communication between the upper equipment and the lower equipment. The bidirectional communication system includes a dual port RAM, the dual port RAM includes an uplink ring buffer and a downlink ring buffer; the uplink ring buffer is used to cache the data packet written by the lower equipment through a lower end ring buffer management component and used for an upper end ring buffer management device to read data; the downlink ring buffer is used to cache the data packet written by the upper equipment through an upper end ring buffer management component and used for a lower end ring buffer management device to read data; and the bidirectional communication system also includes the upper end ring buffer management component and the lower end ring buffer management component. The invention also discloses an implementation method of the bidirectional communication system based on the MSA protocol.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a two-way communication system based on the MSA protocol and an implementation method thereof. Background technique [0002] With the vigorous development of communication technology, the proportion of optical communication is increasing, and the MSA protocol, as a standard protocol framework in the field of optical communication, has been used more and more widely. In view of the actual use scenarios defined by the MSA protocol, hardware dual-port RAM is generally used to realize data interaction between modules, alarm reporting and other functions. Traditional general communication interfaces, such as I2C, SPI, UART, Ethernet, PCIe, etc. are difficult to use directly. It is used to realize the data interaction between modules, or it does not conform to the MSA protocol specification, or it has special requirements for hardware. The current traditional way is to d...
