FRAMEWORK FOR PROVISIONING NETWORK SERVICES IN CLOUD COMPUTING ENVIRONMENT

摘要

This disclosure relates generally to provisioning network services in a cloud computing environment, and more particularly to framework for provisioning network services in a heterogeneous cloud computing environment. In one embodiment, the disclosure includes a network as a service (NaaS) layer under a cloud provisioning platform. The NaaS layer can be interfaced with any cloud provisioning platform. The NaaS layer serves the networking needs of the heterogeneous cloud environment. It provides network services like monitoring, notifications, QoS policies, network topology and other services. For example, the cloud provisioning platform defines a virtual network and attaches a plurality of virtual machines to it. All the communications related to creation/deletion/update of virtual networks, virtual subnets, virtual ports, virtual router, virtual interfaces etc., are sent to the NaaS layer. On receiving the communication, the NaaS layer takes necessary steps to provide the network services as per the needs of the request. Apart from provisioning, the NaaS layer periodically monitors the network elements as well.

主权项

1. A processor-implemented method for provisioning network services in a heterogeneous cloud computing environment, comprising:
receiving, by a cloud provisioning platform, one or more virtual machine provisioning requests from a cloud orchestrator; assigning of compute and storage resources to one or more virtual machine provisioning requests and generating one or more network service requests for at least one of creation, update, and deletion of at least one of virtual networks, subnets, ports, routers and interfaces by the cloud provisioning platform; sending the one or more network service requests to a Network as a Service (NaaS) layer by the cloud provisioning platform for provisioning the network services; and configuring an underlying physical network(s) for each of the one or more network service requests.
