Fresh from the lab, Jimmy Ray takes a question on OTV or Overlay Transport Virtualization. This layer 2 Data Center Interconnect technology is growing in popularity as deployed on the Nexus 7000 as it promises transparent workload mobility, business resilience and superior efficiency with computing resources. This could be THE technology for those of you overcomplicating your network design or simply not attempting certain architectures for you did not know this could be done.
We featured OTV quite awhile back in one of our earlier Fundamental animations. See if this also helps you. Read More »

This week at Cisco live! in San Diego I had a chance to catch up with Jimmy Ray Purser and talk about Cisco’s strategy for programming the network, and specifically programming virtual network slices of a larger physical infrastructure:

As organizations work to evolve their IT infrastructure into a cloud-based model, one concept becomes self-evident: connecting users to the cloud with confidence. In order to achieve that, any virtual infrastructure must have the ability to pool multiple physical devices into a single virtual instance, then expand and contract that instance simultaneously and instantaneously based on application, location or line of business requirements. Such needs further emphasize the importance of design flexibility and scalable deployment models within the WAN. Cisco WAAS provides exactly that and more. But, don’t just take our words for it. Hear directly from our customers at Cisco Live this week. Read More »

Two great new ‘Networking 101’ videos now available. This series is great for anyone needing a quick refresh or touch up on the basics and these two both focus on DNS.
DNS is key to making the Internet accessible to us humans. It’s how we can connect to techwisetv.com without needing to know anything complex from anywhere in the world. How does it know how to do this? DNS can be a complicated topic but understanding the basics does not have to be.
Taking it a step further, DNSSEC is a suite of IETF specifications designed to guarantee the authenticity of data obtained from the domain name system (DNS). Although not designed for confidentiality of the data, this protocol is a great answer for many of the ills that threaten the simplicity of the Internet. Chief Geek Jimmy Ray Purser arms you with how it works and why deployment is not growing as fast as it should be.
