Problems solved by technology

However, this solution requires the network administrator to pre-define the correspondence between packet characteristics (such as IP addresses and port numbers) and service types. When the service flow received by the network device does not include the predefined packet characteristics, such as network address translation (network address translation, NAT) and proxy (proxy) and other scenarios, the network device cannot identify the service type of the service flow, and needs to manually identify the service type, and configure the forwarding policy in the network device based on the identified service type

Embodiment Construction

[0045] In the description of the present application, unless otherwise specified, "plurality" means two or more. In the description of the present application, terms such as "first" and "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order.

[0046] figure 1 A schematic diagram of a possible system architecture provided by the embodiment of the present application is shown as an example. The system includes a source device 101, a destination device 102, a control device 103 and N network devices. figure 1 , network device 1 , network device 2 . . . , network device N are only exemplarily shown, where N is a positive integer. N network devices can form a network topology (not in figure 1 shown in ).

[0047] When the source device 101 sends the service flow to the destination device 102, the service flow may be forwarded by some...

Abstract

The invention discloses a service flow processing method and device. The method comprises the following steps: network equipment receives a first service flow; the network equipment extracts flow characteristics of the first service flow, and the network equipment obtains a first service type corresponding to the first service flow according to a reasoning model and the flow characteristics of thefirst service flow, wherein the reasoning model is obtained by training according to the flow characteristics of the historical service flow and the service type of the historical service flow; the network equipment determines a first forwarding strategy corresponding to the first service type according to a first corresponding relation table and the first service type, wherein the first corresponding relation table comprises a corresponding relation between the service types and the forwarding strategies; and the network equipment forwards the first service flow according to the first forwarding strategy. Thus, the network equipment can identify the service type of the first service flow online through the reasoning model, the timeliness in forwarding the first service flow can be improved, and different service types of service flows can be forwarded automatically and timely.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a service flow processing method and device. Background technique [0002] With the rapid development of the Internet, more and more users use the Internet. Different types of service flows are carried on the network, and different types of service flows have different requirements on the service level agreement (SLA) of the network (such as bandwidth, delay, packet loss rate, and jitter). In order to ensure the satisfaction of user experience for different types of service flows, it is necessary to configure corresponding differentiated services for different types of service flows in the network equipment, such as configuring low-latency paths for service flows with high Configure high-latency paths for less demanding service flows to provide differentiated forwarding services for different types of service flows. [0003] A solution provided in the prior a...
