Embodiment Construction
[0051] In order to make the above objects, features and advantages of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0052] The data processing method in the network device provided in the embodiment of the present invention can be applied to the data plane of the network device. First, the data plane structure of the network device in the embodiment of the present invention will be described, see figure 1 as shown,
[0053] The data plane may include a data packet sending and receiving process 101, a first data packet processing process 102, a first shared memory area 103, and a second shared memory area 104, and the first shared memory area is mapped to the process space of the data packet sending and receiving process and the first In the process space of the data packet processing process, the second shared memo...

The invention discloses a data processing method and system in a network device, which are used to avoid traffic interruption during upgrading. The method includes: the data packet sending and receiving process receives the data packet and puts it into the first shared memory area; the first data packet processing process starts from The first shared memory area obtains the data packet, processes the data packet according to the session table, and the session table and the data packets to be cached are stored in the second shared memory area; the second data packet processing process starts; the second data packet processing process converts the first data packet A shared memory area and a second shared memory area are mapped to its own process space; the second data packet processing process sends an upgrade notification to the first data packet processing process; after the first data packet processing process receives the upgrade notification, it stops from the first shared The memory area acquires the data packet, and after processing the data packet, sends a processing completion notification to the second data packet processing process, and exits the process; after receiving the processing completion notification, the second data packet processing process becomes the first data packet processing process.
Description
technical field [0001] The invention relates to the technical field of network equipment, in particular to a data processing method and system in network equipment. Background technique [0002] Generally, network devices can be divided into two parts: the control plane and the data plane according to their functions. The control plane is used to process protocol packets between network devices and undertake the configuration and management functions of network devices; the data plane is used to receive and send data from the network card of the network device. Data packets, parsing data packets, processing data packets according to the session table, the data plane is the core business logic unit of the network device. [0003] When the data plane software is upgraded, the restart of the data plane process will cause the network device to stop sending and receiving data packets from the network card. At the same time, it will cause the loss of core data structures such as t...
