Scaling NFV – The Performance Challenge

In the second part of my blog series I want to cover one of the main concerns that Services Providers are facing as they explore moving to NFV and that is performance and scalability. Common concerns I hear center around latency, throughput, queuing capabilities and security. These are valid concerns since SP’s have service level agreement (SLA’s) with the their customers which lead to penalties if performance drops below the SLA.  So will a virtualized network function perform at the same level as a purpose built networking device?

Where Virtualization Does and Doesn’t Make Sense – An Optimization Primer

bioShot-sWritten By Wayne Cullen, Senior Manager, Service Provider Architectures

Along with cloud computing, M2M, collaboration, and hoodie sweatshirts, virtualization is a trend du jour. Like all trends, it’s based on an old idea (dating back to the mainframe era) that has now been reimagined for new purposes. One of the newest roles for virtualization is network functions such as those in switches, routers, and network appliances, including firewalls and load balancers—thanks to Network Functions Virtualization (NFV). And this is just the beginning of what is going to be virtualized in your network.

Being a Selective Virtualizer

Virtualization can provide some big cost savings and reduce network complexity. But virtualization is like chocolate. You eat too much and some bad things can happen. The early days of virtualization (when servers were virtualized) provide a cautionary tale. Server virtualization lowered CapEx but led to skyrocketing operational costs because much more complex processes—hence highly-skilled staff—were required.

The lesson: Be selective in virtualizing your resources and functions. And focus your time optimizing your network to lower TCO with a flexible, adaptable infrastructure as part of your virtualization efforts.

Fresh Perspectives on Monetization in Programmable Service Provider Networks

bioShot-sWritten By Wayne Cullen, Senior Manager, Service Provider Architectures

Agility. Scalability. Automation. Orchestration. Programmability. Service providers are exploring such an array of new and exciting capabilities these days! You hear a lot about lowering costs by increasing efficiency and decreasing complexity.

But what about monetization? More specifically, do programmable networks help make you money while also saving it? What are the competitive benefits that lead to higher revenues from service agility and faster time-to-market? According to a 2013 Heavy Reading study, that’s a top expectation of service providers when asked about the potential benefits of software-defined networking (SDN). The Open Networking Foundation (ONF) has also promoted monetization opportunities based on SDN through new service creation and the enhancement of existing ones due to faster service creation, easier scalability, and mass customization.

Part 2 – Virtualized Services in an EPN World?

In part one of this series Gina covered the basic definition of an Evolved Programmable Network or EPN and its linkage to the Cisco Evolved Services Platform (ESP).   Figure 1 offers a quick visual recap.

Cisco Announces Intent to Acquire Tail-f Systems

Every day our world becomes increasingly connected. And as the Internet of Everything (IoE) continues to develop, service providers who provide us with video, voice, and data services are faced with managing explosive growth of demand on their network, including the number of applications and platforms needed to improve the way we live, learn, work and play.

All of this makes networks more complex and expensive to manage.  At the same time, increased competition is driving service providers to introduce new services more rapidly. While Network Function Virtualization (NFV) and network programmability both help improve scale and functionality of networks for service providers, they do not solve the bottleneck caused by operational complexity.

That is why today, I am pleased to announce our intent to acquire Tail-f Systems, a leading provider of multi-vendor network orchestration solutions for traditional and virtual networks. Tail-f will help achieve our goal of aiding customers in their quest to simplify and automate network management, enabling service innovation and deployment acceleration. The acquisition of Tail-f accelerates Cisco’s cloud virtualization strategy of delivering software that increases value to our customers’ applications and services, while supporting Cisco’s long-standing commitment to open standards, architectures, and multi-vendor environments.

Tail-f’s innovative and talented team is also the thought leader around the development and implementation of the NETCONF protocol and YANG data modeling language, which is the leading industry approach to simplifying and automating networks. Tail-f also has an amazing team of talented engineers. Tail-f’s talent and technology, when added to our existing offerings, will enhance how Cisco addresses network orchestration and will help simplify and automate how physical and virtual networks are both provisioned and managed.

We couldn’t be more excited about the opportunity to continue driving leadership in cloud virtualization and orchestration with the addition of Tail-f. Stay tuned for more details in the weeks and months to come.  And welcome Tail-f!
