Problems solved by technology

Among them, the random current limiting scheme is usually purely random current limiting. In this scheme, the data removed and retained are completely random, and the diversity of current limiting data cannot be guaranteed.
The Hash scheme is to judge whether the two data are the same through the calculated Hash value, and to remove the same data first, but it cannot distinguish the two similar data.

Abstract

The invention discloses a data current limiting method and device. The data current limiting method comprises steps of calculating a local sensitive Hash value of received data, calculating a similarity value of the data with at least one piece of data according to the local sensitive Hash value of the data and the local sensitive Hash value of at least one piece of data which is already stored, and determining whether to store the data according to the similarity value. The data current limiting method and device can remove data according to a similarity degree and a difference of the data, can preferentially remove the same data and can maximize the diversity of the data after current limitation.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a method and device for limiting data flow. Background technique [0002] Due to various reasons (insufficient resources, high system pressure, etc.), calls between computer systems often face the situation that flow restrictions need to be performed. Existing current limiting schemes generally include two types, a random current limiting scheme and a hash (Hash) scheme. Among them, the random current limiting scheme is usually purely random current limiting. In this scheme, the data removed and retained are completely random, and the diversity of current limiting data cannot be guaranteed. The Hash scheme is to judge whether two pieces of data are the same through the calculated Hash value, and to remove the same piece of data first, but it cannot distinguish between two pieces of similar data. Contents of the invention [0003] The purpose of this applica...
