Looking for Money in New Places

There are some innovative ways to make money nowadays, and sometimes kids can come up with new ways that we hadn’t thought about.  For examples, we know some kids in the area who are raising money for various charities.  Instead of asking their relatives to sponsor them or going door-to-door to the neighbors to get the money, one child decided to sell duct tape wallets and homemade potpurri, while another decided to sell her book collection to raise money.  Those kids clearly are thinking about new ways to get money for something old and traditional.

In the world of service providers and networks, the demand for new and better services continue to grow, while the networks must expand and quickly adapt to these demands.  One way that operators are evolving their network is to Read More »

Network Dependency Mapping Helps Clean Up Our Application Portfolio

My team is moving hundreds of applications to our new Application Centric Infrastructure (ACI) platform, and network dependency mapping is the first step in this migration. Most of Cisco IT’s applications are three tiered with web and middle tier residing on the same Java Virtual Machine (JVM) connecting to a database.

A typical application may have one or more JVMs that connect to one or more databases. Sometimes the databases internally connect to other databases. Over the last five years, we have heavily invested in Services Oriented Architecture (SOA) and thus have JVMs running web services. These web services are consumed by one or more user interfaces (UI). Some of these applications have jobs that run on our Cisco Tidal Enterprise Scheduler (TES). Read More »

Proving the Value of SD-WAN

In a recent TechTarget survey, it was noted that despite the hypes about numerous benefits of SD-WAN – one of which is the ability to create a hybrid WAN environment (i.e. MPLS and Internet or LTE links), something Gartner claims will be “the new normal,” – only 10% of enterprises plan to deploy hybrid WAN in the next 12 months. The greatest concern for the slow uptake is whether Quality of Service (QoS) can be done over Internet connections. In addition to that, management complexity and security vulnerabilities by going to Direct Internet Access (DIA) are also top of mind. Of the 1,437 that were surveyed, 54% is still in the consideration stage about SD-WAN, and the number one considering factor is to reduce WAN costs. This is not a surprise, but a perplexing issue for CIO, CISO, and IT Admins especially when analysts, like Gartner, and respondents in an April 2015 ETAB Survey, are prescribing SD-WAN as the enterprise’s top IT priorities for the next 3-year.

We will examine the following in this post: a) the State of the WAN in 2015, b) what we hear from customers, and c) a successful, real world SD-WAN deployment.  Read More »

Segment Routing, the engine to Application Engineered Routing

For those, who read my previous blog, you surely want to know more about Application Engineered Routing. As Segment Routing sits at the very heart of Application Engineered Routing, let me start explaining how the former works.

I’m going to draw an analogy between how IP networks route data traffic and how the airline companies transport luggage. The point here is not to get into technical details; for those interested in the nitty-gritty of Segment Routing, I recommend reading the following white paper:

Let’s take the example of a piece of luggage,  Read More »

Application Visibility Makes Parenting Easier!

internet usage-v1.Parenting in a hyper-connected world is increasingly challenged by lack of visibility into children’s internet usage, and by limited controls to customize internet usage policies per child. About a year ago, I installed a home router with parental-controls. My kids (teenage girls!) quickly complained about the additional latency it introduced on the network. User experience was clearly in the tank. I soon discovered that those controls were not granular enough to customize for different times of the day, for different users, and down to individual devices.

By then, I realized that I had to fundamentally rethink my home network in order to become a more effective parent. I needed better insight into my network’s traffic. Finally, last fall, the geek in me awakened and I deployed a full-fledged Cisco network in my home with advanced Application Visibility & Control (AVC) capabilities, providing me deep insight into my home’s internet traffic.
