Problems solved by technology
However, with the development of technology, the difference in bandwidth granularity is getting bigger and bigger, and the deviation between standard Ethernet interfaces and actual application requirements is also getting bigger and bigger.
A very likely situation is that the bandwidth required by mainstream applications does not belong to any existing Ethernet standard rate. For example, if 50Gb / s services are carried by 100GE ports, there will be waste of resources, while 200Gb / s services are currently There is no corresponding Ethernet standard granule that can carry

Embodiment Construction
[0046]The solution provided by the embodiment of the application supports the implementation of FlexE interface on network equipment. The network equipment product forms include core routers supporting FlexE interface, Internet Protocol Radio Access Network (IPRAN) based on network protocol, and packet transport network (packet transport network, PTN) box or frame equipment. First pass belowfigure 2 withimage 3 An exemplary introduction to the principle of data transmission in an existing FlexE group.
[0047]figure 2 Illustratively shows a schematic diagram of a data sending process on the sending device side to which the embodiments of this application are applicable, such asfigure 2 As shown, a FlexE group on the sending device 201 side can include zero, one or more FlexE Clients, such asfigure 2 FelxE Client a, FlexE Client b...FlexE Client z shown in. The data corresponding to each FelxE Client will be encoded and sent to the FlexE Shim. For example, the data corresponding to Flex...

Embodiments of the present application provide a method for adjusting PHYs in a FlexE group, related equipment, and a storage medium, so as to flexibly adjust PHYs in a FlexE group in a working state. The receiving device determines that the first PHY needs to be added to the first FlexE group in the working state, and according to the received data flow corresponding to the first PHY and the data flow corresponding to each PHY in the first FlexE group, the first PHY or the first PHY Each PHY in a FlexE group performs delay offset compensation; and recovers the data flow corresponding to the Client from the PHY of the first FlexE group; if the data flow corresponding to the first PHY corresponds to each PHY in the first FlexE group If the delay deviation of the data stream after the delay deviation compensation is zero, then the data stream corresponding to the Client is recovered from the PHY of the second FlexE group. The second FlexE group is after the first PHY is added to the first FlexE group. The FlexE group, so that the flexibility of adjusting the PHY in the FlexE group in the working state can be improved.
Description
Technical field[0001]This application relates to the field of communications, and in particular to a method for adjusting the PHY in the FlexE group, related equipment and storage media.Background technique[0002]The 802.3 standard Ethernet (Standard Ethernet, StdE) related standards defined by the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE) are widely cited in the industry. Standard Ethernet is very popular with manufacturers for its simple principle, easy implementation and low price. However, with the development of technology, the difference in bandwidth particles is getting bigger and bigger, and the deviation between the interface of standard Ethernet and actual application requirements is getting bigger and bigger. It is very likely that the bandwidth required by mainstream applications does not belong to any existing Ethernet standard rate. For example, if a 100GE port is used for a 50Gb / s service, there is a was...
