Imagine that you have several branch offices that are using WAN demanding applications like Salesforce.com, Office 365, Virtual Desktops, Video Teleconferencing and more. You are using those expensive MPLS/VPN WAN connections as you don’t want to risk it and probably because when you started to work there it was already there and … why mess around with something that is working, right? Normally I would agree with that but when IT budgets are shrinking and the network needs to step up and support those business critical apps, there is no other way but to innovate.
At any given time your network carries information from LAN to WAN and vice versa, some is important and some is less important. In many cases as a network admin you don’t have the visibility to distinguish between them, so what do you do when those critical apps are starting to act up? Usually the answer will be to buy more WAN bandwidth and that will give the apps and the user experience behind them some breathing space. But all you’re doing is buying time. Buying time never solves the problem because you will need to treat the symptoms again in a few weeks or months.
However, you can solve the problem and not just treat the symptoms using Cisco Intelligent WAN or IWAN for short.

We in IT are faced with many challenges from our end users. From IT costs to application performance, while always keeping an eye on our network security posture. This reminds me of a sign on the wall of my auto mechanic’s shop: Good, Fast, Low-cost. I was always told I am allowed to pick only two. I would of course question him, “why cant I have something with high quality, on time, and within budget?” This always made him smile, but he still told me I could only pick two.
So back to our IT challenges: Cost, Performance, and Security. Application performance is something we can all see, feel and touch. When thinking about performance, we need to also consider where these applications are coming from. Looking at applications like Microsoft’s Office 365, we are seeing mission critical applications from outside our data centers being delivered as Software as a Service (SaaS) solution. Does this matter to our end users? They sit at their PC’s, Tablets, Mac’s, etc. and know when something is not going fast enough. Their expectations are growing; they always expect the best performance. If they don’t feel their Outlook e-mail is opening fast enough or that the saving of their PowerPoint file is taking too long, they do not hesitate to let us know. And oddly enough, everyone just assumes it is the network. So not only do we need to think about our networks, but the Internet performance as well.

During the past years WAN optimization devices were used to optimize end-user traffic mainly. Employers connecting to remote applications can achieve better user experience if a couple of WAN optimization are deployed. Typically web applications, file sharing and email can be well accelerated: end users can increase their productivity with a little investment.
On the other side providers usually offer free bandwidth upgrade during a contract renewal.
So the question are:
- Can Data Center replication take advantage of WAN optimization?
- Can a Bandwidth upgrade always supersede WAN optimization?
The answers are, as always: it depends. Read More »

It has been a couple of weeks since its launch and we are seeing lots of interest in the Cisco ISR-AX! I have been hearing from customers, partners and folks worldwide about how they are using the new ISR-AX platforms now and get a router, VPN, firewall, intrusion prevention, cloud/web security, AVC (NBAR2, QoS, NetFlow, Media Monitoring, PfR) and WAN optimization (WAAS) all in one box for less than the cost of just an alternative WAN Optimization appliance. For WAN optimization with WAAS that is less than $1 per WAN optimized connection with ISR-AX!
Anyway, I’ve gotten lots of questions since the launch, so I grouped them and wanted to share the top 4: Read More »

On March 12th, Cisco announced the ISR-AX and how Cisco is changing the game, reducing complexity and making it simpler for enterprises to deliver and manage application delivery to users. Cisco is expanding the role of our Integrated Service Routers (ISRs) to deliver application-centric networks that provide granular visibility, control, and optimization without additional devices or bandwidth upgrades -- Cisco® Application Experience (AX) Router family is now a part of the ISR family of routers! The Cisco ISR-AX Routers directly integrate Cisco Wide Area Application Services (WAAS), Application Visibility and Control (AVC), Data/IPBase and Security services into a platform that is simple to order, configure, and deploy for secure, optimized cloud connectivity and branch-office routing. The Cisco ISR G2 and ISR-AX Routers are based on the same hardware and software that you know and love and are deploying today. Today I wanted to go into the technical details of each of the components. Read More »
