The idea was born in Paris late 2015. 42 Mediatvcom and the R&D Department of public broadcaster France Televisions wanted to build a proof‐of-concept demonstration for broadcasters interested in interconnecting their television studios over IP.
The design parameters: it had to be end-to-end, interoperate across multiple vendors and showcase how studios can migrate to IP using open source components.
Next-generation IP Video routing is part of Cisco’s new “Media Blueprint,” to help broadcasters, content providers and media and entertainment companies make the move to all-IP infrastructure. Cisco’s part in the project involved our Nexus series of IP switches, which make it easier to connect and manage disparate data center resources using software-defined networking (SDN).

Long before before ‘virtual’ became synonymous with servers, Network VLANS gave us a layer 2 answer for much needed network segmentation. It also opened things up for more flexible network designs.
Watch TWTV 186 “Scaling Multitenancy with VXLAN”
As server virtualization exploded however, multiple network design issues began to converge and revealed new issues to overcome:
- Hardware costs rose as Spanning Tree’s lack of multipathing required redundant boxes to lay dormant in the event of failure.
- Larger networks exposed the limited number of segments that VLANs could scale, capping out at just 4,094 segments, (or less when using STP).
- Multi-tenancy put further pressure on VLAN limitations.
The answer to these problems arrived in 2012 as RFC 7348: VXLAN, Virtual Extensible LAN. A network overlay with the entire layer 2 frame encapsulated in UDP by only adding around 50 bytes of overhead.
So now, the 4,094 segment limitation of VLAN had expanded to an incredible 16 million segments with VXLAN. The ability for VXLAN to span layer 3 boundaries was an additional benefit for cloud networks, yet another concept emerging from server virtualization advancements.
Millions of segments, tenant isolation, layer 3 multipathing. No more network issues. Right? Ironically, these larger VXLAN enhanced networks, began discovering new limitations.

My goodness… Were we ever busy in 2015! Our Cisco Big Data & Analytics teams executed and delivered a tremendous body of work with several key accomplishments these past 12 months. All of our activities – across all of our teams – was focused on delivering to you leading innovation, with industry leading performance & scalability, and offering flexibility via a variety of Big Data choices. Of course all of it based on Cisco UCS, Nexus, and ACI. Let’s take a look at some of the highlights:
We introduced throughout 2015 various versions of our 3rd generation Big Data architecture. The solution, Cisco’s UCS Integrated Infrastructure for Big Data, integrates our industry-leading computing, network, and management capabilities into a unified fabric-based architecture. Packaged as a Cisco Validated Designs (CVD) our architecture supports the leading Hadoop distributions: Cloudera, Hortonworks, IBM, and MapR. Our Big Data CVDs provide you peace of mind as they are tested, validated, and supported. Take a peak at our Big Data CVDs here and see how they can expedite your Hadoop projects and drive operational efficiency.

You may wonder what the terms “DevOps, Cisco Open NX-OS and Ansible” have to do with each other. If you plan to visit AnsibleFest 2015 in San Francisco, stop by the Cisco table to learn more.
The DevOps approach has been embraced and pioneered by Web 2.0 customers for some time, and now we’re seeing the trickle of that coming to an Enterprise customer near you. The simple reason is the ability to bring operations and development closer together, enabling faster deployments of applications without breaking the infrastructure. Cisco colleague Luca Relandini expands on DevOps here.
The Cisco Open NX-OS is designed to support the DevOps approach. Shane Corban shares Six Key Points What OPEN means for NX-OS. The concept behind Open NX-OS is to enable operators to make changes in a more programmatic way that drives automation and efficiency in the infrastructure without compromise on security. Visit the developer community to learn and find more scripts using the capabilities of Open NX-OS.
As part of the NX-OS openness, agentless tools like Ansible leverage NX-API to gather real-time state data and to make configuration changes on Cisco Nexus switches. To stay up to date on Ansible solutions, visit the Cisco marketplace.
In this Oct 9th SDxCentral DemoFriday webinar, we showed how Day 0, 1, 2 operations can be accelerated with Ansible. And to stay up to date on the latest Cisco NX-OS Ansible Module Docs, visit the GitHub repository.
