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.

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.

How do we evolve the IT architecture to enable an ever-increasing set of services while multiple MegaTrends are rapidly transforming the environment? How do you deliver the best possible experience to your users and applications while maintaining agility and keeping cost under control?
Today, in my first blog after the summer break, I’d like to start exploring a topic which is critical to building this new architecture supporting current and upcoming Megatrends – and which can be seen as a Megatrend itself as well: Software Defined Networking (SDN) and the Cisco Open Network Environment (ONE) strategy and architecture.
Bruno Klauser, Consulting Engineer in my team has been focusing on Network Programmability and network-embedded automation for some time – and is currently working with many of the early adopters across EMEAR.
Q: Bruno, with Software Defined Networking being an increasingly popular discussion topic we’re hearing a lot of of comments -- from “nothing new at all” to “complete revolution of IT” – what, if anything, is different from how we built solutions in the past? Read More »

Among all the Megatrends that have significant implications from an infrastructure perspective (as discussed here), the one that customers in EMEAR currently expect the most from Cisco is Clouds. Both in terms of technical guidance as well as architectural innovations.
In the Cisco Cloud approach, intelligence in the network can help ensure delivery of cloud services, provide access and services to the right users, and offer the flexibility to connect with public, hybrid, and community clouds.
As shown in the illustration to the right, three main elements must be considered to build an efficient cloud. In addition, the network needs to provide dynamic access to these resources, and the Cloud applications and services must deliver anywhere, anytime access.
With the emergence of Cloud architectures, innovation is required within the network to allow IP to gain two critical features not natively provided by IP today: IP mobility and the Virtual Private Network (VPN). Read More »

In my previous Blogs I have talked about Megatrends including BYOD, the Next-Generation Workspace, Video and the Internet of Things. One unfortunate reality all of these trends have in common is that they are going to put additional stress on your current Network and Security Infrastructure and Operational Process.
TrustSec uniquely offers the welcome opportunity to improve and extend Security Policy Control and the same time make it easier to Operate and Maintain. This post concludes the mini-series on TrustSec. Previous Blogs have looked at TrustSec in the DC and applied to VDI. Here I have asked Dave Berry Cisco TSA to take a step back and look at the bigger picture from Network Access to the DC. Read More »
