PACKET PROCESSING METHOD, APPARATUS AND SYSTEM

摘要

This application provides a packet processing method, a device and a system. The system includes a layer 4 forwarding device, a layer 7 forwarding device, and a controller. The controller sends a first forwarding entry to the layer 4 forwarding device, where the first forwarding entry includes a first keyword and a first processing policy corresponding to the first keyword, the first keyword includes layer 4 information for matching a packet, and the first forwarding entry is used to instruct the layer 4 forwarding device to send a second packet to the layer 7 forwarding device according to the first processing policy when a first packet matching the first keyword is received; and the controller sends, to the layer 7 forwarding device, a control rule used to instruct the layer 7 forwarding device in packet processing.

主权项

1. A packet processing method, applied to a system comprising a layer 4 forwarding device, a layer 7 forwarding device, and a controller, wherein the layer 4 forwarding device and the layer 7 forwarding device separately communicate with the controller, and a data channel used to transmit a packet exists between the layer 4 forwarding device and the layer 7 forwarding device, the method comprising:
sending, by the controller, a first forwarding entry to the layer 4 forwarding device, wherein the first forwarding entry comprises a first keyword and a first processing policy corresponding to the first keyword, the first keyword comprises layer 4 information for matching a packet, and the first forwarding entry is used to instruct the layer 4 forwarding device to send a second packet to the layer 7 forwarding device according to the first processing policy when a first packet matching the first keyword is received; and sending, by the controller, to the layer 7 forwarding device, a control rule wherein the control rule instructs the layer 7 forwarding device in packet processing, ensuring that the layer 7 forwarding device processes the second packet according to the control rule.
