Service delivery method, device and system, and storage medium

A traffic delivery method, applied to a receiving end, comprising:

• receiving a fourth traffic flow through a physical layer (PHY) transport channel;
• wherein the fourth traffic flow is the same as a third traffic flow sent by a sending end for transmitting a traffic to be transmitted;
• generating a fifth traffic flow from the fourth traffic flow transmitted through the PHY transport channel;
• and
• recovering, from all fifth traffic flows, of the traffic to be transmitted according to a FlexE protocol.

A sending end apparatus, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor,
• wherein the processor is configured to:
• determine a number of second traffic flows according to a traffic bandwidth of a first traffic to be transmitted;
• group the second traffic flows of the first traffic to be transmitted according to the number of the second traffic flows and a preset grouping policy to obtain a plurality of traffic groups of the first traffic to be transmitted;
• wherein a number of the traffic groups is equal to a number of physical layer (PHY) transport channels, a total transmission rate of the second traffic flows matches the PHY transport channels;
• and
• generate a third traffic flow according to the second traffic flows, and send the third traffic flow through the PHY transport channel corresponding to the third traffic flow.
