Problems solved by technology
[0004] However, in the existing technology, data centers generally manage their own containers through container orchestration such as Kubernetes (a container orchestration engine open sourced by Google), and different containers have different bandwidth speed limit policies, but Kurbenetes cannot provide services for containers that use RDMA network transmission. Implement an effective bandwidth rate-limiting policy, and the bottom layer of Rsocket still uses RDMA transmission, so Kubernetes cannot implement a bandwidth rate-limiting policy for Rsocket
At present, there is no suitable bandwidth rate limiting mechanism to limit the rate of egress traffic bandwidth and ingress traffic bandwidth of the Rsocket library

The invention relates to the technical field of traffic control, and discloses a bandwidth speed limiting method, system and device for an Rsocket library and a storage medium, and the method comprises the steps: building shared memory communication with a Helper process, and obtaining bandwidth speed limiting information from the Helper process, the bandwidth speed limiting information comprising an expected bandwidth; and sending a speed limiting request to a speed limiter module, the speed limiting request comprising the bandwidth speed limiting information, so that the speed limiter module uses a token bucket algorithm to limit the bandwidth of the Rsocket library according to the expected bandwidth. According to the method and the device, the aim of limiting the speed of the outlet traffic bandwidth and the inlet traffic bandwidth of the Rsocket library can be achieved.
Description
technical field [0001] The present application relates to the technical field of flow control, in particular to a bandwidth speed limiting method, system, device and storage medium for an Rsocket library. Background technique [0002] The Rsocket library (RDMAsocketAPI, RDMA socket application call interface) is a protocol that provides a socket interface on the RDMA network. It is part of the librdmacm library provided by the linux-rdma group and is also part of the OFED library. The main job of Rsockets is to implement the interface Verbs semantics provided by RDMA to adapt all socket calls in order to use the RDMA network. [0003] When inter-process communication in the same host is performed based on the Rsocket library, in order to balance the use of corresponding bandwidth between processes, it is necessary to limit the egress traffic bandwidth and ingress traffic bandwidth of the Rsocket library. [0004] However, in the existing technology, data centers generally m...
