Embodiment Construction
[0073] The technical solution in this application will be described below with reference to the accompanying drawings.
[0074] figure 1 It is a schematic diagram of a network 100 applicable to this embodiment of the application. It includes a first network device, a second network device and a third network device.
[0075] Specifically, the first network device, the second network device, and the third network device are any three network devices in the network 100 . Packets can be forwarded among the three network devices.
[0076] Specifically, the three network devices include a downstream network device and an upstream network device, that is, a packet of the upstream network device can be forwarded to the downstream network device, and then forwarded by the downstream network device.
[0077] For example, the first network device is an upstream network device, and the second network device is a downstream network device of the first network device. Then, the first n...

Embodiments of the present application provide a period mapping method and network equipment. The method includes: the downstream first network device receives the first information sent by the upstream second network device, the first information carries the number of the first period of the second network device, called the first number. The first number includes the first label number and the first group number, and the second label number and the second group number included by the first network device according to the number of the first cycle that can send the first information, the first label number and the first The mapping relationship of the group numbers establishes the mapping relationship between the numbers of the multiple cycles of the first network device and the numbers of the multiple cycles of the second network device. The technical solution provided by the present application can establish a mapping relationship between cycles of different network devices and improve the real-time performance of packet scheduling.
Description
technical field [0001] The present application relates to the communication field, and more specifically, to a period mapping method and network equipment. Background technique [0002] Deterministic networks are currently a hot topic in the industry. The core of deterministic networks is to ensure the end-to-end bandwidth, delay, and jitter of service flows. To meet the end-to-end deterministic delay jitter of packets, it is necessary to implement scalable data plane deterministic packet scheduling. [0003] The packet scheduling method provided in the prior art sets a uniform delay jitter for the entire network. However, the structure of packet scheduling among all network devices in the entire network is inconsistent, and a unified delay jitter is still set for the entire network, which will affect the real-time performance of packet scheduling. Therefore, how to establish the mapping relationship between periods of different network devices in the network and improve t...
