Abstract

An embodiment of the invention provides a network data flow type detection method comprising the following steps: acquiring the header of a first data packet of a current data flow, and acquiring the pattern vector of the current data flow from the header; comparing at least one characteristic dimension in the pattern vector of the current data flow with the corresponding characteristic dimension in the pattern vector of at least one historical data flow to get at least one pattern similarity of the current data flow; predicting the length of the current data flow according to the at least one pattern similarity of the current data flow and the length of at least one corresponding historical data flow; and comparing the predicted length of the current data flow with a preset threshold, and judging whether the current data flow is a large data flow or a small data flow according to the result of comparison. According to the invention, the type of a data flow can be detected by detecting the header of the first data packet of the data flow, the type of a network data flow can be judged in real time, and the accuracy of judgment is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of network data routing, and more specifically, relate to a network data flow type detection method and device and a network data routing method and device for its application. Background technique [0002] Recent studies have shown that in the data center network, about 90% of the data flow is bursty, short-duration, small data flow (small dataflow), also known as mouse flow (miceflow); and only 10% of the data flow The flow is a large data flow with a long duration and a huge flow length, also known as an elephant flow. Although the number of elephant flows only accounts for 10% of the total number of network data flows, the flow of elephant flows (such as the number of data packets, or the total number of data flow bytes) accounts for 90% of the total flow of the entire data center network . Most of the existing routing algorithms (such as EqualCostMuti-Path, ECMP) use the local information ...
