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] 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 to figure 1 Shown in the FlexE network architecture. 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. A network device (such as a first network node, a second network node, etc.) is a device capable of transmitting and receiving data in the flexible Ethernet, such as a router, a switch, etc. 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 includes two optional management channels. One management channel is used for...

The invention discloses a method and system for establishing a flexible Ethernet management channel, and relates to the technical field of flexible Ethernet. The invention judges whether the FlexE PHY carries valid customer service flows, and combines the configuration negotiation mechanism provided by the FlexE overhead: no valid services are carried When streaming, create a high-bandwidth management channel and switch management signaling to the high-bandwidth management channel for transmission; when carrying effective customer service flows, switch management signaling to the user-configured management channel for transmission, and delete the high-bandwidth management channel. At the same time, before the effective customer service flow is partially or completely deleted, the management signaling is switched to the undeleted management channel configured by other users or the established high-bandwidth management channel for transmission; when all effective customer service flows are deleted, the high-bandwidth management channel is re-created and The management signaling is switched to the high-bandwidth management channel for transmission to meet the high bandwidth occupation requirements of the management signaling.
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 (FlexE for short) is an improved network based on Ethernet. The flexible Ethernet technology supports multi-channel 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 alignment of the signals of each FlexE instance in the FlexE group is realized by inserting the FlexE overhead block into the 66b coded stream carried in the group. FlexE overhead consists of a 66b block, and on a 100G FlexE instance, a FlexE overhead block occurs approximately every 13.1 microseconds. The actual format of the FlexE overhead block is repeated in the form of 8 consecutive blocks, so the...
