Method and system for guaranteeing cloud computing server cluster network

Abstract

The invention discloses a method for guaranteeing a cloud computing server cluster network. The method comprises that a virtual machine resource distribution management module initializes server cluster network topology, server cluster calculation, and storage resource provided by an administrator; that a request dispatching management module receives a server creating request submitted by a tenant, that service request placement analysis is executed according to the server cluster network topology, the server cluster calculation, and the storage resource in the virtual machine resource distribution management module in order to determine a server corresponding to the server creating request and to be placed by the virtual machine; and that according to an analyzed result of the virtual machine placement in the request dispatching management module, the virtual machine resource distribution management module creates a virtual machine on a server corresponding to the virtual machine in a virtual machine cluster and updates the server cluster calculation and the storage resource. With a provided network resource reservation and adjustment scheme, the method not only guarantees the isolation of network resources of the tenant, but also increases the utilization rate of network resources.

Description

technical field [0001] The invention belongs to the technical field of computing system virtualization, and more specifically relates to a multi-tenant-oriented cloud computing server cluster network guarantee method and system. Background technique [0002] Cloud computing has changed the way applications are created and run, using the Infrastructure as a Service (IaaS) model, where tenants deploy computing and software on third-party infrastructure and pay on demand. In a cloud computing environment, tenants deploy their applications in a shared environment. Each tenant's service consists of virtual machines deployed on a server cluster. Since tenants cannot trust each other, in a shared server cluster, cloud computing needs to provide performance guarantee among untrusted tenants. However, the existing mechanism lacks performance guarantee for server cluster network I / O resources. [0003] Unlike CPU and memory, network resources are more difficult to manage. Because i...

Problems solved by technology

Virtual machines on the same server compete with each other for link bandwidth, and the virtual machine communicating with it affects the actual network usage of the virtual machine; in addition, TCP congestion control in traditional networks can only provide best-effort service (Best-effort). It can only achieve fairness between network flows, not between tenant virtual machines
