Problems solved by technology
Due to the limited bandwidth of the management channel (1.222Mb / s, 1.833Mb / s), it is impossible to cope with high bandwidth occupation scenarios such as management signaling data traffic bursts and equipment software upgrades, which has become a management bottleneck for new equipment nodes in the communication network

Embodiment Construction
[0058]The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0059]The technical solutions provided by the embodiments of the present invention are applicable tofigure 1 In the network architecture of FlexE shown. The flexible Ethernet includes at least two network devices (a first network node and a second network node), which are connected through at least one flexible Ethernet interface. Network devices (for example, the first network node, the second network node, etc.) are devices that have data transceiving functions in the flexible Ethernet, such as routers and switches that support the flexible Ethernet function. There is at least one Ethernet physical link between the first network node and the second network node.
[0060]figure 2 It is a schematic diagram of the FlexE overhead frame structure. The FlexE overhead contains two optional management channels. One management channel is used for segment-layer...

The invention discloses a flexible Ethernet management channel establishment method and system, and relates to the technical field of flexible Ethernet. According to a configuration negotiation mechanism which is provided in combination with FlexE overhead by judging whether FlexE PHY bears effective customer service flow or not, the method comprises the following steps: creating a high-bandwidthmanagement channel and switching the management signaling to the high-bandwidth management channel for transmission when effective client service flow is not carried; when the effective client serviceflow is carried, switching the management signaling to the management channel configured by the user for transmission, and the high bandwidth management channel is deleted; before the effective customer service flow is partially or completely deleted, switching the management signaling to an undeleted management channel configured by other users or an established high-bandwidth management channelfor transmission; when all the effective client service flows are deleted, creating again the high-bandwidth management channel, and switching the management signaling to the high-bandwidth management channel for transmission, wherein the high-bandwidth occupation requirement of the management signaling is met.
Description
Technical field[0001]The invention relates to the technical field of flexible Ethernet, in particular to a method and system for establishing a flexible Ethernet management channel.Background technique[0002]Flexible Ethernet (Flexible Ethernet, referred to as FlexE) is an improved network based on Ethernet. The flexible Ethernet technology supports multiple flexible rate FlexE client MAC technology by binding one or multiple Ethernet interfaces defined by the IEEE802.3 standard, and on this basis, the 66b coding block is used as the basic unit for channelization processing.[0003]The signal alignment of each FlexE instance in the FlexE group is realized by inserting FlexE overhead blocks into the 66b coded stream carried in the group. The FlexE overhead consists of a 66b block. On a 100G FlexE instance, a FlexE overhead block appears approximately every 13.1 microseconds. The actual format of the FlexE overhead block is repeated in the form of 8 consecutive blocks, so the period of t...
