Bandwidth isolation device and method

Abstract

The invention provides a bandwidth isolation device and method, and the device comprises: a message receiving module which is used for obtaining a data message through a drive program; a bandwidth determination module which is used for determining a target bandwidth occupation proportion corresponding to the header information of the data message according to a corresponding relationship between apreset bandwidth selection condition and a bandwidth occupation proportion, wherein the bandwidth selection condition is constructed for the header information of the data message; and a scheduler which is used for sending the data message according to the target bandwidth occupation proportion. According to the invention, the packaged data message is analyzed and processed; according to the preset corresponding relation, the header information of the data message is directly mapped to the corresponding target bandwidth occupation proportion to be sent; and the execution logic is simple, no protocol coupling exists, and the constraint of a user mode or a software / hardware kernel mode is avoided, so that all transmission protocols can be supported and compatible, and the isolation requirement of higher performance can be met while the application range of the bandwidth isolation scheme is expanded.

Description

technical field [0001] The present application relates to the field of information technology, in particular to a bandwidth isolation device and method. Background technique [0002] With the development of Internet technology, in many cases, there may be multiple tasks accessing the network, and in order to ensure the optimal utilization of network bandwidth resources, bandwidth isolation is required. [0003] At present, when sending messages, there are three common bandwidth isolation schemes. Scheme 1 uses a built-in TC (traffic control, flow control) framework in the kernel of the transmission system. The TC framework supports various Qdisc (queueingdescipline, queuing rules) , the TC framework realizes bandwidth isolation during message transmission based on a locked scheduling queue through the implementation of the software kernel state. Option 2: Packets are transmitted through ETS (Enhanced Transmission Selection, Enhanced Transmission Selection Protocol) at the p...

Problems solved by technology

[0004] However, the inventor found in the research process that: in the current scheme, scheme 1 implements bandwidth isolation in a pure software kernel mode, which involves data processing at the software level and cannot support high-performance bandwidth isolation scenarios at the pure hardware level, for example, rdma (remote direct memory acess, remote direct memory access), solution 2 needs to modify the corresponding fields in the message, resulting in a maximum of 8 groups of bandwidth isolation restrictions, making the efficiency of bandwidth isolation too low, solution 3 because it will introduce Additional virtualization system overhead makes the processing logic for bandwidth isolation too complex. Therefore, the current bandwidth isolation solution has a limited scope of application and cannot meet high-performance isolation requirements.
