Non-traditional players will test 5G too.
This week, the Internet Society announced the six recipients of funding from its Beyond the Net initiative. Among these amazing projects (you can read more about them here) is the San Francisco Bay Chapter’s Bridging California's Rural/Urban Digital Divide with Mobile Broadband initiative.
As I was trying to automate configuration deployment in a multi-router Cisco IOS lab, I got to a point where the only way of figuring out what was going on was to log commands on Cisco IOS devices. Not a big deal, but I hate logging into a dozen boxes and configuring the same few lines on all of them (or removing them afterwards).
Time for another playbook: this one can push one of many (configurable) configuration snippets to a group of Cisco IOS devices defined in an Ansible inventory file.

You don’t have to look far to see the amazing things that organizations are doing with big data technology: pulling information from past transactions, social media and other sources to develop 360-degree views of their customers. Analyzing thousands of processes to identify causes of breakdowns and inefficiencies. Bringing together disparate data sources to uncover connections that were never recognized before.
All of these innovations, and many more, are possible when you can collect information from across your organization and apply data science to it. But if you’re ready to make the jump to big data, you face a stark choice: should you use a pre-integrated “out-of-the-box” platform? Or should you download open-source Hadoop software and build your own?

This post was updated on 2/22/17 to reflect the official launch of EVPN. You can now access EVPN in general availability. Read the white paper to learn more about this exciting new feature.
When we set out to build new features for Cumulus Linux, we ask ourselves two questions: 1) How can we make network operators’ jobs easier? And 2) How can we help businesses use web-scale IT principles to build powerful, efficient and highly-scalable data centers? With EVPN, we believe we nailed both.
Many data centers today rely on layer 2 connectivity for specific applications and IP address mobility. However, an entire layer 2 data center can bring challenges such as large failure domains, spanning tree complexities, difficulty troubleshooting, and scale challenges as only 4094 VLANS are supported.
Therefore, modern data centers are moving to a layer 3 fabric, which means running a routing protocol, such as BGP or OSPF between the leaf and spine switches. In order to provide layer 2 connectivity, between hosts and VMs on different racks as well as maintain multi-tenant separation, layer 2 overlay solution is deployed such as VXLAN. However, VXLAN does not define a control plane to learn and exchange Continue reading
