specific Embodiment 1

[0166] The working principle block diagram is as follows Figure 7 As shown, the flexible Ethernet port is composed of two PHYs. After negotiation at both ends, the FlexE SHIM management entity uniformly numbers the two PHYs, which are PHY0 and PHY1. Two flexible Ethernet services are FlexE Client1 and FlexE Client2. The OAM is generated and inserted by the OAMBlock Generator (OAM Block Generator) module at the originating end, and the OAM is received by the OAM BlockReassemble (OAM Block Reassembler) module at the receiving end. detection. The method to detect the fault is to detect each PCS Lane separately. When the receiver corresponding to this PCS Lane receives abnormal data, according to the corresponding relationship information between FlexEClient and PCS Lane, you can get the information corresponding to the PCL Lane. The number of the FlexEClient processed by OAM, assuming that all PCS Lanes were normal before, and now after testing, it is found that some kind of OA...

specific Embodiment 2

[0169] Figure 8 The schematic diagram of the network that the transport network is not aware of FlexE is provided for the present invention. It can be seen that in this case, the FlexE SHIM, in a router, maps the FlexE client on a group of bound Ethernet PHYs.

[0170] Figure 9 The flowchart of the channel management method of the flexible Ethernet provided by the present invention specifically includes:

[0171] The first step is to let two ports directly connected through Flexible Ethernet technology negotiate, so that both parties can perceive the mapping relationship between PCSLane and FlexE Client; in this example, it shows that four 100Gbps PHYs are bound into one For a FlexE link, at this time, there are 4 lanes in each 100Gbps. In this embodiment, a sub-rate of 50 Gbps is prepared for each PHY. Therefore, the OAM status corresponding to two Lanes on each PHY will reflect the real situation of the sub-rate PCS Lane. As long as one of the PCS Lanes belonging to th...

specific Embodiment 3

[0183] The scenario of this embodiment is a stream carrying a higher rate. is still Figure 8 , the difference from Embodiment 1 is that there is one incoming flow, and four PHYs are required. At this time, since the failure of a single high-speed FlexE end is equivalent to the failure of the group, the mechanism of the present invention is also applicable to this scene.

[0184] The first step is to let two ports directly connected through Flexible Ethernet technology negotiate, so that both parties can perceive the mapping relationship between PCSLanelane and FlexE Client; in this example, it shows that four 100Gbps PHYs are bound into one For a FlexE link, at this time, there are 4 lanes in each 100Gbps. In this embodiment, the input data traffic of the FlexE Client is 400Gbps, and each PHY carries a rate of 100Gbps. Therefore, the OAM state corresponding to any lane on each PHY (that is, the state of the PMD) will reflect the real situation of the FlexE Client PCS Lane:...

Abstract

The present invention provides a flexible Ethernet lane management method and apparatus. The method comprises the steps of when OAM information of a PCS Lane is acquired, acquiring a target FlexE Client corresponding to the PCS Lane according to a pre-acquired correspondence between the PCS Lane and the FlexE Client; and determining OAM information of the target FlexE Client according to the OAM information of the PCS Lane.

Description

technical field [0001] The invention relates to the field of flexible Ethernet of the optical interconnection forum, in particular to a channel management method and device of the flexible Ethernet. Background technique [0002] At present, the fixed bandwidth Ethernet interface hides the flexibility of the grouping device. The grouping device only provides a single stream with a fixed bandwidth to the outside world, which makes it impossible to play its inherent flexibility, let alone extend this flexibility to the same flexible Therefore, a flexible Ethernet (Flexibe Ethernet, FlexE) is proposed. [0003] For data packet forwarding equipment, such as Ethernet routers / switches can handle flows of substantially flexible bandwidth; in packet equipment, data packets flow through the network processor (Network Processor, NP) unit and traffic management (Traffic Management, TM) unit, both of which have strong traffic bandwidth control capabilities. Based on these two units, an...
