Embodiment 1

[0072]The present invention controls the loopback operation by selecting 20 bits in the reserved field of the overhead frame and setting three fields. The field Field_A represents the loopback command, and 2 bits are used to represent different loopback commands. Among them, the 2 bits of Field_A can represent 4 values, and the two non-zero values ​​a and b are selected to represent the remote loopback request and the remote loopback respectively. Response; the field Field_B indicates the loopback type, and 2bits are used to indicate different loopback types. Among them, the 2bit of Field_B can indicate 4 values, and the two non-zero values ​​​​c and d are selected to indicate Shim loopback and Client respectively. Loopback; when the loopback type is Client loopback, the 16-bit Field_C field is valid, indicating the Client_ID of the loopback. Among them, when the value is 0, it means that all clients are not looped back; when the value is 0xffff, it means that all clients are ...

Embodiment 2

[0088] Such as Figure 6 As shown, this preferred embodiment binds 4 100G PHYs to form a FlexE Group, supports 75G and 150G 2 FlexE Clients, represents 75G Client with client 1 (Client_1), and represents 150G Client with client 2 (Client_2); 4 PHY members, numbered The PHY Number is 0 to 3. For the convenience of expression, PHY_0, PHY_1, PHY_2, and PHY_3 are respectively used to represent the PHY corresponding to the PHY Number. In this embodiment, the Filed_A field is bit12 to bit13 of the second overhead block, 01 indicates the remote loopback request, and 10 indicates the remote loopback response; the Filed_B field is bit14 to bit15 of the second overhead block, and 01 indicates the Shim layer ring Back, 10 means Client loopback; Field_C field is bit16~bit31 of the second overhead block. When the loopback type is Client loopback, the 16-bit field Field_C field is valid, indicating the Client_ID of loopback. When the value is 0, It means that all clients are not looped bac...

Embodiment 3

[0099] Such as Figure 6 As shown, in this preferred embodiment, four 100G PHYs are bound to form a FlexE Group, which supports two clients of 75G and 150G. 4 PHY members, numbered PHY_NUM is 0~3. 75G and 150G 2 Client numbers are 1~2 respectively. For the convenience of expression, PHY_0, PHY_1, PHY_2, and PHY_3 are respectively used to represent the PHY corresponding to the PHY Number. Use Client_1 to represent 75G Client, and Client_2 to represent 150G Client. In this embodiment, the Filed_A field is bit12 to bit13 of the second overhead block, and Filed_A is 01 to indicate a remote loopback request, and Filed_A is 10 to indicate a remote loopback response; the Filed_B field is bit14 to bit15 of the second overhead block, and Field_B 01 means Shim layer loopback, Field_B is 10 means Client loopback; Field_C field is bit16~bit31 of the second overhead block, Field_C is 0 means all clients are not looped back, Field_C is 0xffff means all clients are looped back.

Abstract

The invention discloses a remote loopback detection method, communication equipment and a computer readable storage medium. The remote loopback detection method comprises the steps that: a FlexE loopback request side sends two or more first data blocks to a FlexE loopback response side; furthermore, a first overhead block is inserted among the pre-set fixed number of first data blocks; the first overhead block comprises remote loopback request indication and remote loopback type indication; the FlexE loopback request side receives two or more second data blocks returned by the FlexE loopback response side and a second overhead block inserted among the pre-set fixed number of second data blocks; and the second overhead block comprises remote loopback response indication. According to the remote loopback detection method, the communication equipment and the computer readable storage medium disclosed by the invention, the remote loopback request indication, the remote loopback type indication and the remote loopback response indication are set in a FlexE overhead block; the loopback detection function of remote equipment is realized in the Shim layer of a flexible Ethernet; furthermore, loopback of some data blocks is appointed; non-loopback of some data blocks is appointed; and thus, the fault of the Shim layer can be detected more conveniently.

Description

technical field [0001] The present invention relates to but not limited to the technical field of Flexible Ethernet (FlexE), and in particular relates to a remote loopback detection method, a communication device, and a computer-readable storage medium. Background technique [0002] Currently, the Optical Internet Forum (OIF) is discussing the expansion of traditional Ethernet application scenarios to support functions such as sub-rate, channelization, and inverse multiplexing for Ethernet services, and calls this Ethernet technology It is Flexible Ethernet (FlexE, Flexible Ethernet). For example, for the sub-rate application scenarios of Ethernet services, Flexible Ethernet can support the use of 250G Ethernet services (Media Access Control (MAC) code stream) using three existing 100GE physical media layer (Physical Medium Dependent, PMD) for transmission. For the inverse multiplexing application scenario of Ethernet services, the flexible Ethernet can support the transmi...
