1. A method of routing Flex Ethernet, FlexE, data in a network, the method comprising:
receiving data on a first FlexE physical layer, PHY, group;
determining, from a first FlexE overhead on the first FlexE PHY group, that data in one or more first time slots on the first FlexE PHY group is associated with a predetermined path in the network, wherein the first FlexE overhead comprises at least two calendar configurations for assigning each of the one or more first time slots to one or more receiving clients, wherein the first FlexE overhead further comprises a calendar switch request bit that is configured to be used by the sending node to send a request to the receiving node to switch a currently used calendar configuration;
determining a second FlexE PHY group for the data in one or more second time slots based on at least a portion of the predetermined path in the network, wherein information identifying the one or more second time slots to be used for sending the data to the second FlexE PHY group is indicated in the first FlexE overhead on the first FlexE PHY group; and
sending the data on the second FlexE PHY group.
