Abstract

The invention discloses a bandwidth control method and device of a distributed file system. By collecting the current data amount and the number of current data packets of the samba network layer; according to the current data amount and the number of current data packets, the current network bandwidth and the current network bandwidth are respectively calculated. Current packet rate; compare the current network bandwidth with the preset bandwidth; the current network bandwidth is greater than the preset bandwidth, and calculate the rated packet rate according to the current packet rate, current network bandwidth, and preset bandwidth; call the delay function to control the samba network The packet inflow rate of the TCP interface of the layer, so that the packet inflow rate is equal to the rated packet rate. In this application, when the current network bandwidth is greater than the preset bandwidth, the packet inflow rate of the TCP interface of the samba network layer is controlled to be equal to the rated packet rate, so as to control the flow of the samba network interface, realize the bandwidth control of the distributed file system, and reduce the flow of the distributed file system pressure, thereby improving the stability of the distributed file system.

Description

technical field [0001] The invention relates to the field of file systems, in particular to a bandwidth control method and device for a distributed file system. Background technique [0002] With the development and progress of storage technology, distributed file systems are more and more widely used. [0003] In the AS13000 product, bandwidth control is not implemented in the entire functional chain from the client to the underlying file system. At this time, when the client accesses AS13000 with high traffic volume in a short period of time, it will generate high business traffic pressure on the file system of AS13000, which may cause problems such as data not being placed on the disk in time, and the cache is too large, thereby reducing the AS13000 distributed system. stability. Contents of the invention [0004] The purpose of the present invention is to provide a bandwidth control method and device for a distributed file system, aiming to solve the problem of low s...
