Presented by: Jeff Peterson, Entry Point

This presentation will explore an Optical Network Terminal (ONT) replacement that provides cloud functionality at the subscriber edge in a carrier network. The new ONT - a Virtual Broadband Gateway (VBG) - is used to transform an incoming optical signal to an electrical and/or wireless signal for voice, data, and other services. The VBG is a single instance of hardware that is used to create multiple virtual routers, switches, and service demarcations using Open vSwitch, NFV, and SFC (Service Function Chaining). The VBG is being used to simplify the network at the subscriber premise and to provide a point of presence at the premise for all of the network stakeholders (network operator, service provider, and subscriber).

The VBG includes the following features:

* Linux-based OS
* Dataplane - Open vSwitch
* OpenFlow capable
* Supports multiple virtual machines (Cloud at the Edge)
* Supports Service Function Chaining (SFC)
* Supports Network Functions Virtualization (NFV)
* Supports software (CPU) switching
* Supports Trusted Platform Module (TPM)
* Supports Virtual Analog Terminal Adapter (V-ATA)
