Have you ever been behind the wheel of your car moving at 5 mph? Visualize this: as I wait patiently for my turn to merge onto Interstate 880 N, based on the honor system because there is no meter, a brightly colored Fiat rolls by on the left shoulder. A few seconds later, a Smart Car inches up and squeezes itself between my car and the narrow right shoulder passing me as well. The Smart Car has a bumper sticker that says “Please don’t hit me. I’m not sure about my coverage.” Hmm…
Now that you’re probably done giggling at my experience, let’s analyze the scenario above. Designing a network of highways takes a lot. A smart highway system not only reduces congestion and prevents collision, but also provides expedient information, such as signage and speed sensors, to improve driver response times. Civil engineers consider more than just current traffic and road conditions when they design highway systems. They also consider how to scale for the future, taking into account urbanization, seasonal factors, and future uncertainties such as mini cars. Sound familiar?
Many of the design and management considerations for an Internet wide area network—such as bandwidth management, application response time, and centralized control—are similar to highway system design.

In my first post on IPv6 peering, I provided some sample questions for your ISP and discussed considerations for the physical implementation. After the physical details have been worked out, the next step is how to set up the control plane so that routing information can be exchanged. From a routing perspective, most providers prefer that you peer with them either using BGP or static routing. Static routing is typically used for single, homed organizations that do not want or need a dynamic routing capability. In this case, the organization has a default route to the ISP, and the ISP distributes the organizational routes via the ISP BGP process.

Hear how financial innovator Diebold gains visibility and control of the 87,000 devices on their network. David Kennedy, Chief Security Office @ Diebold recognizes there is no stopping the new mobile devices and sets course to secure his organization while ensuring the business may continue to generate revenue. Workers want to work their way securely and prefer that the security is transparent so that they have the optimal experience. He speaks to the unique granularity that the Cisco Identity Services Engine (ISE) offers to segment access by user, device, access method, posture and time. So, engineers may get access to their code base while marketing professionals like me have no access from my new iPad:

Change. It’s part of how we work, live, and play. Change is inevitable and often feared rather than embraced. However, change could be a catalyst for innovation, a new way of doing things faster and more efficiently. It allows companies to capitalize on opportunities, creating strategic long-term value while also meeting immediate operational needs.
The market is changing and so is the IT landscape. By 2014, more than 70 million virtual desktops will be connected and 90% of organizations will allow work applications on personal devices (Gartner, 2010). Similarly, by 2015, 1.5 billion mobile devices will connect to the network (Gartner, 2011). These transitions add intense burden to the network, from manageability to security, availability, and scalability. IT leadership often turns to stopgap measures such as getting faster WAN links to handle increased traffic. But that doesn’t solve everything. Organizations that want to propel forward (i.e. be competitive) must change their focus – that is focus not only on bandwidth management, features, and bytes, but also on business agility – giving themselves room to grow. One pharmaceutical services company did that with Cisco Borderless Networks infrastructure. Read More »
