Scalable Tenant Networks

Abstract

Template-driven locally calculated policy updates for virtualized machines in a datacenter environment are described. A central control and monitoring node calculates and pushes down policy templates to local control and monitoring nodes. The templates provide boundaries and/or a pool of networking resources, from which the local control and monitoring node is enabled to calculate policy updates for locally instantiated virtual machines and containers.

Description

RELATED APPLICATIONS[0001]This application claims priority to U.S. provisional application No. 62 / 267,664, filed Dec. 15, 2015, and entitled “Scalable Tenant Networks”, the entirety of which is hereby incorporated by reference into this application.BACKGROUND[0002]Managing change in a datacenter has always been difficult. In the early days, people had to manually connect cables and update configuration files. Automation technologies and techniques such as Dynamic Host Configuration Protocol (DHCP), dynamic Domain Name System (DNS) registrations, Virtual Local Area Networks (VLANs), and switch management scripts lightened the load. Datacenters have experienced massive growth. To enable more flexibility, a new generation of technologies and techniques have been created such as network virtualization and network functions virtualization (NFV). These create flexibility to manage this new hyperscale datacenter. Recently, another variable has been added to the equation: containers and nes...

Benefits of technology

[0003]This Summary is provided in order to introduce simplified concepts of the present disclosure, which are further described below in the Detailed Description. This summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.

[0004]Examples of the present disclosure provide template-driven local policy updates for virtualized machines in a datacenter environment. A central control and / or monitoring node (e.g., a “central controller”) calculates and pushes down policy templates to local control and / or monitoring nodes (e.g., the “local controllers”). The templates provide boundaries and / or a pool of networking resources, from which the local control and / or monitoring node is enabled to calculate policy updates for locally instantiated virtual machines and containers. The local control and monitoring node is configured to monitor the allotted resource utilization, and request from the central controller additional or updated templates and resources for those virtual machines and containers within its control.

Problems solved by technology

Managing change in a datacenter has always been difficult.

This flexibility and multi-tenant isolation will add complex management overhead and ultimately, scalability.
