Problems solved by technology

[0004] For example, for the switch shared cache, there is an essential conflict between high cache utilization, high fairness and high bandwidth and less packet loss. Among them, high cache utilization requires that as much as possible be cached for the incoming data packets to the cache In this way, data packets in other queues may not be cached due to less available cache space, thus, there is a "starvation" phenomenon; on the contrary, high fairness and high bandwidth require reservation of cache space , to prevent sudden traffic

Embodiment Construction

[0068] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0069] In related technologies, in order to make the cache space management algorithm of the network scene target different types of traffic patterns, it can well take into account the high cache utilization rate, high fairness and high bandwidth of the network environment and less packet loss, so as to ensure that the traffic data The processing effect of the user hopes to be able to test and verify the cache space management algorithm of the set network scene...

Abstract

The embodiment of the invention provides a test flow data generation method and device and electronic equipment, and relates to the technical field of computers. The method comprises the following steps: determining a to-be-distributed flow load; determining an allocation mode of the traffic load to be allocated, and allocating a target destination port in a specified network scene to the trafficload to be allocated based on the allocation mode; determining a flow mode of the to-be-distributed flow load, and determining a transmission parameter of the to-be-distributed flow load based on theflow mode; generating a test flow file about the flow load to be distributed based on the sampling result, the target destination port and the transmission parameter, and returning to execute the stepof determining the flow load to be distributed until the number of the obtained test flow files meets the set number; and generating flow data corresponding to each obtained test flow file. Comparedwith the prior art, by applying the scheme provided by the embodiment of the invention, the test flow data which is effective and reasonable and can completely cover various flow modes in probabilitycan be generated.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method, device and electronic equipment for generating test flow data. Background technique [0002] With the continuous development of network technology, the complexity of the network has become higher and higher, and the traffic patterns of various network scenarios have also shown complex and changeable characteristics. Among them, the so-called traffic pattern refers to: During the transmission of the traffic data of the scene, the transmission mode of the traffic data. For example, a micro-burst traffic mode in which traffic bursts occur in a short period of time, a definite traffic mode in which the destination port is determined and continuously transmitted, a mixed mode in which micro-burst traffic and definite traffic are mixed, etc. [0003] When different types of traffic patterns appear in the network scene, the cache space management algorithm of the network sc...
