Systems and methods for chaining control-plane virtual functions for ensuring end-to-end quality of service (QoS) of internet services

A method comprising:

• simultaneously operating a QoS chaining system on a virtual infrastructure over multiple services across multiple users;
• managing Internet service delivery on the virtual infrastructure via multiple Virtual Network Functions (VNFs) which operate on a control-plane of the QoS chaining system;
• monitoring and controlling data-plane service elements and/or network elements via a corresponding VNF in the control-plane;
• and
• providing end-to-end QoS of Internet services across the data-plane service elements and/or network elements via an End-to-End (E2E) orchestrator that coordinates the multiple VNFs,
• wherein the QoS chaining system is operable to perform diagnostic and optimization functions in real-time, on demand and across the multiple VNFs,
• wherein by operating on quality of service (QoS) data and configurations in the control-plane, QoS chaining operates at a higher abstraction layer than network service chaining, and
• wherein the multiple VNFs are configured to be chained, to communicate directly with each other, to communicate directly with the E2E orchestrator, to communicate with each other through the E2E orchestrator, and to communicate through a shared database.

A method of instantiating and terminating a QoS chain for an Internet service at a control-plane of a virtual infrastructure comprising:

• receiving a request for the Internet service by a user;
• confirming the request is in compliance with a policy;
• establishing the QoS chain and instantiating Virtual Network Functions (VNFs) in the control-plane;
• assigning resources by the VNFs for the Internet service in their respective domains;
• confirming sufficient resources exist in their respective domains to transport a video stream;
• and
• enabling an end-to-end datapath through service elements and network elements while simultaneously diagnosing and optimizing the Internet service,
• wherein the QoS chain is operable to provide real-time services operations that support the video stream, and
• wherein by operating on quality of service (QoS) data and configurations in a control-plane, QoS chaining operates at a higher abstraction layer than network service chaining, and
• wherein the VNFs are configured to be chained, to communicate directly with each other, to communicate directly with an E2E orchestrator, to communicate with each other through the E2E orchestrator, and to communicate through a shared database.
