US 2019/0173802 A1 · SLA-BASED RESOURCE ALLOCATION METHOD AND NFVO

Abstract

Embodiments of the present invention provide an SLA-based resource allocation method and an NFVO. The method includes: receiving, by an NFVO, a network service instantiation request, where the network service instantiation request includes an identifier of an SLA of a network service; determining, by the NFVO based on the identifier of the SLA of the network service, an NFVI SLA parameter required for instantiating the network service; further obtaining, from a VIM based on the NFVI SLA parameter, a virtual resource meeting a requirement of the NFVI SLA parameter; and instantiating the network service based on the obtained virtual resource. In the method, the NFVO considers the NFVI SLA parameter when applying for the virtual resource, so that the obtained virtual resource meets a user requirement and a qualification hit rate of resource application is improved.

Dependent claims

An SLA-based resource allocation method, comprising:

receiving, by a Network Functions Virtualization Orchestrator (NFVO), a network service instantiation request, wherein the network service instantiation request comprises an identifier of a Service Level Agreement (SLA) of a network service;
determining, by the NFVO based on the identifier of the SLA of the network service, a Network Functions Virtualization Infrastructure (NFVI) SLA parameter for instantiating the network service;
obtaining, by the NFVO from a Virtualized Infrastructure Manager VIM based on the NFVI SLA parameter, a virtual resource meeting a requirement of the NFVI SLA parameter;
and
instantiating, by the NFVO, the network service based on the obtained virtual resource.

2 more elements

A Network Functions Virtualization Orchestrator (NFVO), comprising one or more processors configured to execute program modules including:

a receiving module, configured to cause the one or more processors to receive a network service instantiation request, wherein the network service instantiation request comprises an identifier of a Service Level Agreement (SLA) of a network service;
a determining module, configured to cause the one or more processors to determine, based on the identifier of the SLA of the network service, a Network Functions Virtualization Infrastructure (NFVI) SLA parameter required for instantiating the network service;
an obtaining module, configured to cause the one or more processors to obtain, from a Virtualized Infrastructure Manager (VIM) based on the NFVI SLA parameter, a virtual resource meeting a requirement of the NFVI SLA parameter;
and
an instantiation module, configured to cause the one or more processors to instantiate the network service based on the obtained virtual resource.
