OPEN: A Fundamental Part of the Network of the Future

Over the past several years, I’ve been lucky enough to be a part of two important trends in the networking industry -- the evolution of open standards and open APIs, and the definition of policy as the key interface to the network.

Open is an extremely important word to the future of networking. The simple dictionary definition for open means not closed or locked, allowing access to inside, and freely accessible.

The ultimate networking environment will allow a user the freedom to connect anything together in the cloud and to an existing environment. In order for this vision to happen, companies must work together to create a common language.

OpenStack has garnered a lot of interest in the development community and among our customers.  We at Cisco have been actively helping to shape the discussion around policy.  Working collaboratively with our partners and competitors, we helped create Group-Based Policy (GBP), an intent-driven policy API for OpenStack.

The Group-Based Policy initiative represents a significant innovation in how users conceive, manage, deploy, and scale their applications in OpenStack clouds.  And its now available as a 100% open source solution available to any vendor.  When coupled with Cisco Application Centric Infrastructure, we are able to offer our customers a completely policy-driven network.

SAP HANA Tailored Data Center Integration (TDI) expanded for Networking

Cisco embraces SAP HANA TDI for Networking

SAP recently announced that they have expanded their SAP HANA Tailored Data Center Integration (TDI) to include networking.   So what does this mean?  It means that if a SAP customer installs SAP HANA, and that same customer has enough capacity on their existing networking equipment to satisfy the SAP HANA certification requirements for networking, then the customer can utilize their existing networking architecture for SAP HANA without having to purchase additional equipment to meet those requirements.

Networking Goes Social

As you probably know, networking can bring your career to a new level. Who you meet can open a variety of doors – you’re able to meet new clients, gain referrals, meet future peers, find a mentor, or begin a new partnership. The possibilities are endless.

Gone are the days where you would print out a stack of business cards and keep them in your wallet to hand out wherever you go. Now, with the digital age, your business card is your social presence. Interacting with someone digitally is the new norm; connecting with a colleague on LinkedIn, tweeting at your favorite brand or company, sharing your favorite articles on Facebook – these are all ways to network from right behind the keyboard.

Networking Goes Social

So, what’s the benefit of getting active on social networks? Here are my top three benefits for taking your networking skills to the computer:

Reach Brands Directly. Many brands are active on social media and are curious about how their customers and partners are using their products. Use this to your advantage and start a conversation about their latest launch, an article they posted, or good customer service. They’ll likely respond back with a follow-up question or a kind note as a way to thank you for reaching out.

Save Time and Money. While you should continue to go to live events when possible, you can network through social channels whenever and wherever you go. You can reach out to brands on Twitter, Facebook or LinkedIn through your phone or desktop without the hefty price tag that comes with traveling.

Interact with Industry Leaders. If you refer to an article written by an industry leader, tag them by using @[their handle]. On Twitter, for example, many company executives and brands will favorite or retweet your post as a way of engaging back. It’s a way of interacting with people you might otherwise not get the chance to.

Integrating ACI & Nexus 2000-7000

As the breadth and depth of the ACI solution continues to grow, so does customer interest.  Many customers who have invested in, and continue to invest in, the Nexus 2000-7000 switches find the ACI vision very compelling.  So, this leads to a logical question regarding how an existing Nexus 2000-7000 fabric will integrate with an ACI fabric.

In short, customers can leverage current Nexus products and add ACI capabilities to their data centers in an incremental manner.  Integrating ACI into an existing Nexus environment will not require replacement of existing Nexus switches.  The benefits of ACI policy can be extended to apps on both physical and virtual servers within the existing Nexus fabric.  This can be achieved as follows (double click on the graphic below to launch the 3+ minute presentation):

In this scenario, the existing Nexus fabric is serving as an optimized transport for an ACI overlay solution.  However, this solution is very different from other industry overlay solutions.   It’s different in that the ACI overlay provides integrated/embedded support for both physical and virtual servers, it allows use of existing L4-7 infrastructure, while providing the automation functionality of the ACI policy model.

If you’d like to learn more, there is a summary, as well as a white paper available.  There is also this video whiteboard session that covers a subset of the elements mentioned above.

3 Steps for Best-in-Class Wi-Fi

If you are a professional photographer or even an amateur like me, you want to have ready access to various control dials on your camera to capture the moment perfectly. Professional cameras provide high level of control to get the best outcome. But there are times when you want to put the camera and the lens in Auto mode or wish that the camera could automate some decisions that make your workflow easier.

Likewise, Cisco Wireless LAN products provides the level of quality, functionality and control that is unmatched and hands-down the best enterprise wireless networking portfolio in the industry. But there are scenarios where it is preferable to expedite wireless configuration with best practices automatically enabled and easy access to data to simplify monitoring and troubleshooting workflow. For example, a small business owner manages his own network or in a K-12 a librarian acting like a part-time IT administrator. This not only provides operational efficiencies for the IT organization but also improves end-user and partner experience.

Cisco WLAN Express Setup is an attempt in this direction. It is now available on 2500 Series Controller (CT2504) starting with software release 7.6.120.0.

It includes three components

  • Easy-to-use setup wizard: This eliminates the need for console cable and command line setup. Instead, 3-step web-wizard is used to quickly boot strap a Controller and configure employee and Guest WLAN out of the box.
