Published on

Session delivered by Scalar on Network Functions Virtualization. NFV allows for:
Rapid Service Deployment
– Ability to template and image NFV devices
– Deployment is as easy as copying an image and
spinning up a new VM
– Integration with Orchestration Stack
Elasticity
– Ideal for situations where temporary but large
scale increases in traffic and services exist
Lower Deployment Costs
– No additional hardware to purchase, as long as
resources exist in virtual environment

  1. 1. Network Functions Virtualization November 22, 2013 Mike Anastasakis Systems Engineer mike.anastasakis@scalar.ca © 2013 Scalar Decisions Inc. Not for distribution outside of intended audience
  2. 2. INTRODUCTION TO NFV © 2013 Scalar Decisions Inc. Not for distribution outside of intended audience
  3. 3. }  Over two-thirds of x86 server workloads are virtualized today, according to Gartner }  Virtualization driven by increased demand for: –  Rapid Service Deployment –  Elastic Computing Requirements –  Requirement for lower deployment costs }  Some of these same demands exist in networking which is why Network Functions Virtualization (NFV) is quickly becoming a hot trend © 2013 Scalar Decisions Inc. Not for distribution outside of intended audience
  4. 4. }  Virtualizing network functions such as: –  Stateful Firewalls –  Routers –  Application Delivery Controllers / Load Balancers –  VPN Devices }  Running these functions on virtualized x86 servers instead of expensive, dedicated ASIC based appliances © 2013 Scalar Decisions Inc. Not for distribution outside of intended audience
  5. 5. }  A group was formed under the ETSI (European Telecommunications Standards Institute) called “Network Functions Virtualization” }  Published a white-paper in October of 2012 calling for virtualization of network functions }  Members such as: AT&T, BT, China Mobile, DT, NTT, Orange, Telecom Italia, Telefonica, Telstra, Verizon }  http://portal.etsi.org/NFV/NFV_White_Paper.pdf © 2013 Scalar Decisions Inc.
