Embodiment 1

[0046] The embodiment of this application can be applied to figure 1 shown on Flexible Ethernet, it is also possible to figure 2 On the network architecture shown, such as figure 2 As shown, the network architecture includes: at least two routers, and flexible Ethernet services are transmitted between the routers through the OTN network.

[0047] In this embodiment, an application to figure 1 shown in Flexible Ethernet or figure 2 Flexible Ethernet overhead multiframe locking method in the network architecture shown, image 3 It is a flow chart of a flexible Ethernet overhead multiframe locking method according to an embodiment of the present invention, such as image 3 As shown, the process includes the following steps:

[0048] Step S302, performing framing processing on the flexible Ethernet overhead frame in the flexible Ethernet physical layer PHY;

[0049] Step S304, performing a locking operation on the flexible Ethernet overhead multiframe, wherein, when it is...

Embodiment 2

[0091] Such as Figure 8 As shown, it is an application scenario of FlexE over OTN termination. A 140G and 10G customer service needs to be transmitted from route A to router B, and a 50G customer service needs to be transmitted from route A to router C. Router A, Router B, and Router C span an OTN network, and the rate of each Ethernet PHY is 100G. In this scenario, process processing includes:

[0092] Step 1. When the OTN ingress node receives the Ethernet PHY from router A, it decomposes each Ethernet PHY to the sub-Calendar.

[0093] Step 2: Perform framing processing on the FlexE signal in each Ethernet PHY. If it enters the frame out-of-lock state and fails to enter the locked state after continuously detecting 160 FlexE frames, report a frame out-of-lock alarm and suppress the alarm. All alarms generated by FlexE overhead detection. If the frame lock is entered, the information of a time slot in the sub-Calendar stored in the overhead frame structure can be obtained...

Embodiment 3

[0128] This embodiment also provides an OTN device, including the Ethernet multiframe locking device in Embodiment 2. It should be noted that, for the explanation of the Ethernet multiframe locking device, reference may be made to the explanation of Embodiment 2, which will not be repeated here.

Abstract

The invention provides a flexible Ethernet overhead multiframe locking method and device and an OTN (Optical Transport Network) device. The method comprises the steps of carrying out frame fixing processing on flexible Ethernet overhead frames in flexible Ethernet PHYs; and under the condition that the frame fixing is successful, carrying out locking operation on the flexible Ethernet overhead frames, and when it is detected that a first preset condition is satisfied, entering an overhead multiframe locking state. Through application of the method, the device and the OTN device, the problem that in related technologies, flexible Ethernet overheads are not obtained accurately is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a flexible Ethernet overhead multiframe locking method and device, and OTN equipment. Background technique [0002] Flexible Ethernet (Flexible Ethernet, referred to as FlexE) technology was initiated by the International Standardization Organization OIF in March 2015 and the relevant technical documents were formally voted in March 2016. Flexible Ethernet technology provides a general mechanism to transmit a series of services with different Media Access Control (MAC) rates. It can be a service with a relatively high rate of a single MAC, or a service with a relatively small rate of multiple MACs. The collection of services is no longer limited to a single MAC rate service; the general structure of flexible Ethernet is as follows figure 1 shown. Flexible Ethernet includes three general capabilities: binding multiple Ethernet PHYs with the same rate to transmit services with a...
