Embodiment approach

[0115] In the first implementation manner of S20411, S20411 is specifically: if the second flow includes the transmission requirements of the second flow, the first network device transfers the second flow received by each network device in the network at least one historical moment The second flow requirement is used as a constraint condition of the path computation unit PCE.

[0116] In the second implementation manner of S20411, S20411 is specifically: if the second traffic includes the second identifier, and the second identifier corresponds to the transmission requirement of the second traffic, the first network device first obtains from each network device in the network at least Extract the second identifier from the second traffic received at a historical moment, then determine the transmission requirement corresponding to the second identifier according to the mapping relationship between the demand identifier and the transmission requirement, and use the transmission ...

Embodiment approach and S206

[0158] In some cases, when the first network device determines the first transmission path, in addition to referring to the above information, it may also consider the flow value of the first traffic in the first time period in the future, so that the determined first transmission path can meet the requirements of the first transmission path. A bandwidth requirement of a traffic in a first time period in the future. Based on this, the embodiment of this application provides a second possible implementation manner of S203 and S206, which are specifically as follows:

[0159] S206: The first network device predicts a predicted traffic value of the first traffic within a first time period according to the first traffic.

[0160] The first time period refers to a preset time period after the current moment. For example, within the first time period may refer to within 3 seconds after the current moment. In addition, the first time period may be preset, especially may be set acco...

Abstract

The invention discloses a path determination method and related equipment. The method comprises the steps that first network equipment receives first traffic, and determines at least one first candidate path corresponding to the first traffic according to a destination address of the first traffic and a second address of the first network equipment, and the first network device determines a first transmission path of the first flow from the at least one first candidate path according to the network state information of the link in each first candidate path at the current moment. Visibly, since the data volume of the network state information of the at least one first candidate path is far smaller than the data volume of the network state information of the whole network, when the first network device determines the first transmission path from the at least one first candidate path, only the network state information with the smaller data volume needs to be referred; the method does not need to refer to the whole network state information with a large data volume, thereby effectively reducing the network resources consumed for determining the path, and improving the determination efficiency of the path.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a path determination method and related equipment. Background technique [0002] In the network, the data transmission process usually needs to be realized by the controller, which is specifically: after the controller receives the path calculation request sent by the network device, the controller needs to determine the network device according to the network status information of the entire network at the current moment. The transmission path of the service flow received at the current moment, and the transmission path is sent to the network device, so that the service flow received by the network device at the current moment can be transmitted according to the transmission path received by the network device. Wherein, because the controller needs to refer to the network state information of the whole network to determine the path, the path determination ...
