AUDIOCODES APPLICATION NOTE
Network Function Virtualization (NFV) and the Virtualization of the Edge

The adoption by service providers of Network Function Virtualization (NFV) and virtualization of the edge enables
them to quickly introduce new innovative communication services to their customers without the overhead typicallyassociated with hardware-based solution deployments. Realizing this opportunity requires flexible Virtual Network
Function (VNF) session border controllers (SBCs) capable of running both as service provider access and peering
SBCs as well as VNFs on Universal Customer Premises Equipment devices (uCPE).
AudioCodes offers a comprehensive and flexible set of solutions, from uCPE devices that can host third-party
VNFs to a scalable virtual SBC. AudioCodes’ virtual SBC runs on any uCPE device as well as in the service provider’s
NFV cloud, functioning as an access or peering SBC. By offering a single scalable product, covering all capacity
needs with one unified control and management interface, service providers can leverage its deployment andmaintenance simplicity to introduce new communications services rapidly and cost-effectively.

SBC VNF for uCPE
AudioCodes’ SBC VNF has the lowest hardware footprint in the industry,enabling service providers to deploy a cost-effective uCPE device atcustomer premises. The SBC VNF supports cloud automation andprovisioning mechanisms to assist service providers in reducing OPEX
and time to service by automating the entire SBC VNF lifecycle.

Service providers have the flexibility to deploy the SBC VNF on any leading hypervisor platform while preserving
the same rich functionality as on the proprietary hardware SBCs.
AudioCodes offers network-wide pool licensing for effective deployment within distributed architectures, enabling
service providers to automate the process of launching new SBC VNFs and to scale them up and down according
to customer demand.

Network Function Virtualization (NFV) and the Virtualization of the Edge

Universal Customer Premises Equipment (uCPE)
Universal Customer Premises Equipment (uCPE) represents one of the strongest use cases of Network Function
Virtualization (NFV) currently attracting the interest of hosted service providers. uCPE provides a remotely
manageable platform on which hosted service providers can easily deploy, modify or delete VNFs over Wide AreaNetworks (WAN).
While traditional white box solutions are good at handling compute platform requirements such as CPU, memoryand storage, it can sometimes be challenging to add different WAN interfaces to the white box. Service providers
want to use the same CPE regardless of whether their access type is legacy T1, Ethernet, xDSL, fiber or even LTE.
The issue of single box solutions becomes even more challenging when it comes to legacy voice interfaces like FXS,
BRI and PRI. In this situation, customer premises include devices such as phones, fax machines or even local PBXs
which may require additional boxes and wiring to support them.
AudioCodes’ uCPE solution, based on its Mediant 800 platform, directly addresses this problem – and solves it.
The solution integrates a state of the art, x86 based server with flexible compute power (2 to 16 cores) based on
the required application, as well as various WAN interfaces and multiple flexible PSTN interfaces on the LAN side.
This facilitates flexible usage in different customer premises.
The AudioCodes uCPE solution is a single, flexible unit for hosting multiple VNFs. It also provides:• Remote management for simplified operations and reduced OPEX
• Compatibility with OpenStack and major third-party orchestrators• Real zero touch installation• Embedded support for data routing, SBCs and media gateways

Network Function Virtualization (NFV) and the Virtualization of the Edge

AudioCodes Virtualized Session Border Controllers
AudioCodes offers two options for taking advantage of Network Function Virtualization.
These are the Mediant Virtual Edition (VE) and the Mediant Cloud Edition (CE) session border controllers.

Mediant Virtual Edition (VE)Mediant Cloud Edition (CE)The AudioCodes Mediant Virtual Edition (VE) SBC is ideal for enterprises and service providers looking to virtualize
their infrastructure and harmonize their datacenters on commodity server hardware. Designed to meet ETSI NFVISG requirements, the Mediant VE runs on leading NFV platforms and uCPE devices, as well as native servers. It iscompatible with leading hypervisors and orchestration solutions.
The AudioCodes Mediant Cloud Edition (CE) SBC leverages the benefits of cloud agility to allow enterprises
and service providers to fully realize the potential of virtual environments by offering full cloud elasticity that
automatically adjusts rapidly to changing needs. Its microservices architecture and scalable media cluster enable
new revenue-generating communications services to be introduced simply and with minimal capital outlay.
Both the Mediant VE and the Mediant CE support broad SIP interoperability and provide powerful media handlingcapabilities (including transcoding) and robust security mechanisms.
