Title: NETWORK DEVICE UPDATE METHOD AND NETWORK DEVICE
Abstract:
The present application discloses a network device update method and a network device, and pertains to the field of communication networks. The method comprises: a first MPU acquiring a new version of software for an entire device; the first MPU notifying a second MPU of installation of a new version of software for the second MPU; the first MPU and the second MPU updating software of each of at least two LPUs, LPUs other than a first LPU forwarding data when software of the first LPU is updated; and the second MPU controlling each updated LPU to forward data. In the present invention, when the first LPU is updated, the first MPU controls the other LPUs in a network device to forward data, so that the network device can forward data by using some of the LPUs during the update, thereby resolving the problem in which the data forwarding capability of a communication network is low during update of a network device in the related art, and improving the data forwarding capability of the communication network during update of the network device.
