Understanding NFV in 6 videos

If the adage says a picture is worth a thousand words, then a video should worth a million. In today’s post I offer you a quick way to fully understanding Network Functions Virtualization (NFV), Software Defined Networking (SDN), and some of its related trends through six short videos, ranging from the very basics of virtualization and cloud concepts, to the deepness of today’s architecture proposed for the NFV installations.

What “the heck” are virtualization and cloud about?

A short and self-explanatory video from John Qualls, President and CEO of Bluelock, covering the very basics of data centres transition towards virtualized models.

What is the difference between NFV and SDN?

This great summary from Prayson Pate, Chief Technologist at Overture Networks, highlights the differences and similarities between NFV and SDN, and how are these complemented in the telecoms industry.

Let us talk about the architecture

Now the basics are established we can see the overall architecture. Look at these diagrams from HP and Intel where they show the main components involved.

So, wait a minute, what is that thing they call OpenFlow?

The following video from Jimmy Ray Purser, Technical host for Cisco TechWise and BizWise TV, explains OpenFlow in a quick and straight way.

What about OpenStack?

This piece from Rackspace, featuring Niki Acosta & Scott Sanchez, makes a great summary about OpenStack, its origin, and its situation in the industry.

Now, what are the challenges faced and some real cases for the carriers?

Now that the concepts are clear and defined, we can study a couple of real use cases scenarios in the carriers’ network and its architecture, as well as methods for addressing the challenges faced in the NFV evolution. In the following video Tom Nolle, Chief Architect for CloudNFV, presents Charlie Ashton VP Marketing and US Business Development at 6Wind, and Martin Taylor CTO at Metaswitch Networks, covering some use cases like the Evolved Packet Core (EPC) and the Session Border Controllers (SBC) based on NFV.


Wrapping up, where are the vendors and the operators at with NFV?

The following pitch features Barry Hill, VP Sales & Marketing from Connectem Inc., at the IBM Smart Camp 2013 hosted in Silicon Valley. It covers a summary of the market opportunity for NFV, their specific solution for the operators EPC, and a brief check on the carriers’ status with it.

Although the ETSI ISG group for NFV definition will most likely publish the standards for it in one year from now, it is already a reality, and all the vendors and operators are working on it in some way or another. No matter if you are just starting to explore this trend, or mastering it already, I hope these videos gave you something about it you did not know before.

About Videoscape Unity

Cisco announced its Videoscape TV services delivery platform at CES in 2011. Videoscape Unity was created by integrating Cisco Videoscape with the assets and business model of NDS, the leading video software and content security and experience provider acquired by Cisco in 2012. The new platform comprises a set of cloud, network and client based components, connected by open interfaces.

• The cloud and network components power new, personalized video services and enable multiple screens to be synchronized to create a single unified experience for the subscriber, so things look and feel the same no matter what device they use.
• Client components use the Cisco Snowflake interface design model and NDS Media Highway multiplatform clients. This approach enables network operators to design exciting user experiences, engineer them into clients for connected devices and set-top boxes, and quickly deploy them across multiple screens and throughout large service footprints.

Flexible Deployment Options

• Videoscape Unity can be deployed in one of many end-to-end pretested configurations, which can be tailored to each operator's service plan.

• Operators can also opt to select individual components and tailor them into their operations via open interfaces.
• For the first time, Cisco is offering Videoscape "as a service," allowing operators to have Cisco build, monitor, operate and even host their video infrastructures.

Advantages for Operators

• Compelling multiscreen experiences delivered from the leading video experience platform and continuosly refreshed by Cisco's 7,500+ video engineers.

• A modular open platform, which operators can enhance with third-party components using open interfaces built into the Videoscape Unity platform.
• For operators that deploy Videoscape Unity for one service can easily enhance and add to the modules they initially deploy to bring other services to market quickly.
• Reduced operations costs by the elimination of single-service, "siloed" platforms, and the need for constant in-house engineering to keep platforms current.

Static Routes with Fast Failure Detection

How do we could protect against blackholing traffic in a network that was only configured with static routes?

You know those pesky problems that arise when two routers are connected on opposite ends of an Ethernet Switch or wan transport gear. A failure on one side of the link leaves the link up on the other side. Fiber cuts, clumsy engineers, failed equipment all can cause a static route blackhole. So how do we protect against this type of failure? That is a very good question and the answer is by using BFD (Bidirectional forwarding detection)

The Configs

Router 3

[edit]
jparks@J2350-1-R3# show routing-options
static {
    route 10.0.3.4/32 {
        next-hop 10.0.2.6;
        bfd-liveness-detection {
            minimum-interval 300;
            multiplier 3;
            neighbor 10.0.3.4;
            local-address 10.0.3.3;
        }
    }
}
router-id 10.0.3.3;
autonomous-system 65006;

Router 4

[edit]
jparks@J2350-2-R4# show routing-options
static {
    route 10.0.3.3/32 {
        next-hop 10.0.2.5;
        bfd-liveness-detection {
            minimum-interval 300;
            multiplier 3;
            neighbor 10.0.3.3;
            local-address 10.0.3.4;
        }
    }
}
router-id 10.0.3.4;
autonomous-system 65116;

Summary

If you need a way to prevent static routes from blackholing traffic in your network.  BFD will be your best answer. It is configurable to detect failure in milliseconds and can be applied on just about any protocol used in the network.
