Data processing method, apparatus, network device and storage medium

A data processing method, which is applied to a network device in a WAN, wherein the network device is located on a specified path from a gateway of a first data center to a gateway of a second data center, the network device is the gateway of the first data center;

• the method comprises:
• storing an acquired first packet of a target service type in a first scheduling queue corresponding to a deterministic flow to which the first packet belongs, wherein a source address of the first packet is an address of a first host in the first data center, a destination address of the first packet is an address of a second host in the second data center, and a forwarding path of the deterministic flow to which the first packet belongs is the specified path;
• wherein storing the acquired first packet of the target service type in the first scheduling queue corresponding to the deterministic flow to which the first packet belongs, comprises:
• receiving a second packet, wherein a source address of the second packet is the address of the first host in the first data center, and a destination address of the second packet is the address of the second host in the second data center;
• generating the first packet forwarded along the specified path based on the second packet if a characteristic of the second packet matches a pre-configured packet characteristic for the target service type;
• and
• storing the first packet in the first scheduling queue, which is a scheduling queue corresponding to the deterministic flow to which the first packet belongs;
• forwarding the packet in the first scheduling queue when a scheduling period of the first scheduling queue is reached;
• determining a second scheduling queue according to whether a packet of the target service type is received within a preset duration before a current moment, if the characteristic of the second packet does not match the pre-configured packet characteristic for the target service type;
• storing the second packet in the second scheduling queue;
• and
• forwarding the packet in the second scheduling queue according to a forwarding strategy corresponding to the second scheduling queue.
