Embodiment Construction
[0025] In the prior art, for a network device including multiple boards, during the configuration upgrade process, some boards can be configured and upgraded first, and another part of the boards can be used to ensure the normal startup and data forwarding functions of the switch, and gradually upgrade each board in the switch. The configuration of the board is upgraded. For a network device including a single board, since it does not have other boards to maintain its normal startup and data forwarding functions, when upgrading the board used to save its configuration files, it is necessary to first Shutdown, upgrade the configuration of the boards in the network equipment in the shutdown state. After the board configuration upgrade is complete, restart the network device to realize the data forwarding function. At this time, the stop of the network equipment will easily lead to the disconnection of important communication, seriously affecting the stability and reliability of...

The invention discloses network equipment and a configuration upgrading method thereof. The network equipment comprises a central processing unit (CPU), an FPGA (Field Programmable Gate Array) and an external chip connected in sequence, wherein the network equipment has a first mode in a normal working state and a second mode in an upgrading state; in the first mode, the FPGA serves as a data channel between the CPU and the external chip; and in the second mode, the CPU writes the current connection information of the network equipment into the FPGA, and the FPGA maintains the current connection. When the network equipment comprising a single board card is in the normal working state, the FPGA serves as a data channel between the CPU and the external chip, and in the configuration updating process of the network equipment, the FPGA acquires the current connection information and maintains the current connection, so that important communication interrupt caused by upgrading of the network equipment is avoided, and the stability and the reliability of the network equipment are improved.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a network device and a configuration upgrading method thereof. Background technique [0002] At present, with the advancement of the network era, network equipment is becoming more and more important in communication. There are many types of network devices and they are increasing day by day. Basic network devices are: computers (whether they are PCs or servers), hubs, switches, bridges, routers, gateways, network interface cards (NICs), wireless access points (WAPs), printers and modems, fiber optic transceivers , optical cable, etc. [0003] In the process of improving the performance of the network equipment, it is often necessary to upgrade the configuration of the network equipment, so that the network equipment can provide new functions or make the inherent functions of the network equipment more usable. Taking a switch as an example, for a switch that includes mul...
