METHOD FOR DETERMINING A PACKET FORWARDING PATH, NETWORK DEVICE, AND CONTROL DEVICE

摘要

The application provides a method for determining a packet forwarding path, a network device acquires device information of the network device and interface information of the network device, so that the network device can send the device information of the network device and the interface information of the network device to a control device by using an IGP, so that the control device determines a packet forwarding path from the network device to the control device according to the device information of the network device and the interface information of the network device. Each network device that sends device information and interface information of the network device by using an IGP does not need to compute a packet forwarding path from the network device to a corresponding control device; therefore, decreasing a processing burden of the network device.

1. A method for determining a packet forwarding path, wherein the method is applied to a centralized system in which controlling and forwarding are separate, and the system comprises a control device and a network device managed by the control device, the method comprising:
acquiring, by the network device, device information of the network device and interface information of the network device; and sending, by the network device, the device information and the interface information to the control device by using an Interior Gateway Protocol (IGP) so that the control device determines a packet forwarding path from the network device to the control device according to the device information and the interface information.
