A service flow adjustment method and a communication apparatus are provided. Slot adjustment information is carried in a client signal flow sent between nodes, so that times at which all nodes on a network switch slot configuration can be unified, to avoid service damage in a process of adjusting a network transmission bandwidth. The method includes: A first node receives a first client signal flow from a second node by using N slots of a first bundling group; and after first duration starting from a time at which the first node detects slot adjustment information, the first node receives the first client signal flow from the second node by using M slots of the first bundling group.

A receiving device determines that a first PHY needs to be added to a first FlexE group in a working state. The receiving device performs a deskew on the first PHY or each PHY in the first FlexE group based on a received data stream corresponding to the first PHY and a received data stream corresponding to each PHY in the first FlexE group, and restores a data stream corresponding to a client from a PHY in the first FlexE group. If a skew between the data stream corresponding to the first PHY and the data stream corresponding to each PHY in the first FlexE group after the deskew is performed is zero, the receiving device restores a data stream corresponding to a client from a PHY in a second FlexE group so that flexibility of adjusting a PHY in a FlexE group in a working state is improved.
