Enterprise networks are special. They require bomb-proof design, micro-second convergence and service-level agreements so good that the WAN will only be down for half a second every year scheduled six weeks ahead of time for midnight over a holiday weekend. That’s what we’re taught from the time we’re young Network Engineers sitting on our parents’ knees. An Enterprise network is something special they taught us. We should never consider running our mission-critical traffic over the dirty, unreliable Internet! Such talk would be blasphemy akin to looking for a date at a funeral. It might work for some, but our network is special and must be treated that way.
So what is all of this talk then, coming from Cisco no less, of using Internet links to run an Enterprise-class network? Cisco recently introduced the Intelligent WAN (IWAN) solution that promotes exactly this sort of “illicit” behavior. So what’s changed?
In the first part we discussed how video services are evolving within enterprise networks. Content may be sourced from internal servers, BYOD end points or external content providers, thereby creating a mix of managed and unmanaged services. This has led not only to growth in traffic, but also a competition for actual resources between the different types of services.
We have discussed how these services are evolving, now moving to a per application, per session model which ensures that specific resources are allocated depending on the nature of the usage. Tools such as those provided by the medianet architecture, combined with changes in defaulting all traffic within the VPN session back to the corporate network, contribute to this evolution in session management.
Once again, we turn to Thomas Kernen to provide some insight into how recent technology improvements are designed to help with managing video traffic growth and enabling better content distribution models.
This week we have two opportunities for you to learn about Cisco technologies from company experts as well as our technology partners.
The first webinar,How Smarter Branches Lower Costs, is on Wednesday, December 11 at 8am Pacific and discusses how Cisco Intelligent WAN (IWAN) along with Akamai’s Unified Performance solution can help your branch offices can realistically utilize Internet as WAN for a cost-effective, reliable, and secure option.
A preview for this webinar is a quick video we did with Akamai in October!
With several key applications moving to the clouds, how do our customers ensure application performance? What if they deploy for instance Public or Private Hosted solutions or hybrid WAN, how do they ensure application experience?
Today, we all see more and more new delivery models such as Private Cloud, Hybrid Cloud or Public Cloud, new Hybrid WAN deployment replacing or complementing MPLS by internet link to reduce cost and enhancing application delivery, Audio and Video applications deployed in enterprise, applications going HTTP or HTTPS making them more complex to detect.
How does the network play a critical role in the application experience that enterprises need to provide today to their users? How can you rely on the network to provide enough agility, flexibility and control with so much new applications, deployment models and delivery methods.
Enterprise today need to be able to rely on the network as well to handle all those new challenges. IT organizations need the ability to identify, monitor applications running on the network, define policies and better control and classify those applications, to provide the best end user experience, and keep up with new request growth but without having to replace all the actual infrastructure.

The ongoing trend towards consolidating branch infrastructure started with consolidating services like firewall and VPN into your branch router. Next came server consolidation and virtualization using modules like the UCS E-Series for the ISR G2. All bring the benefits of lowering total cost of ownership, maintenance costs and reducing network complexity in the branch.
One of the great things about working for Cisco is that we get to see the full spectrum of customer requirements. The next trend that I am seeing is customers asking about how to integrate standalone switches into a branch router without compromising on security or performance. Read More »
