Method and Apparatus for Processing Low-Latency Service Flow

A first forwarding device, comprising:

• a non-transitory computer-readable storage medium storing programming instructions;
• and
• a processor coupled to the non-transitory computer-readable storage medium, the programming instructions causing the processor to be configured to:
• obtain a low latency identifier corresponding to a first service flow after determining that a received first data packet belongs to the first service flow, the first forwarding device serving as a network ingress;
• obtain a second data packet based on the first data packet and the low latency identifier, the second data packet comprising the first data packet and the low latency identifier, the low latency identifier instructing a forwarding device receiving the first service flow to forward the first service flow in a low-latency forwarding mode, and the low-latency forwarding mode being a mode in which fast forwarding of the first service flow is implemented under dynamic control;
• and
• send the second data packet to a second forwarding device in the low-latency forwarding mode.

A second forwarding device, comprising:

• a non-transitory computer-readable storage medium storing programming instructions;
• and
• a processor coupled to the non-transitory computer-readable storage medium, the programming instructions causing the processor to be configured to:
• receive a first data packet from a first forwarding device, the first data packet comprising a low latency identifier, the low latency identifier instructing a forwarding device receiving a first service flow to forward the first service flow in a low-latency forwarding mode, the low-latency forwarding mode being a mode in which fast forwarding of the first service flow is implemented under dynamic control, and the first data packet belonging to the first service flow;
• and
• send the first data packet in the low-latency forwarding mode based on the low latency identifier.
