iOS 9 – A Growth Hacking Opportunity Awaits

The Economics of Network Downtime

Infonetics Research recently released a study that claims businesses (just in North America alone) lose as much as $100 million a year due to network downtime. Let us dissect that into numbers you and I can relate to.

  • On average, businesses suffer from 14 (CA Technologies) to 87 hours (Gartner) of downtime per year.
  • A conservative estimate pegs the hourly cost of network downtime at $42,000 (Gartner).
  • The cost of unplanned downtime per minute is between $5,600 and $11,000 (Ponemon Institute).
  • MTTR (mean time to resolution) per outage, on average, is 200 minutes (ITT Process Institute).

For a quick/rough calculation of your own potential revenue lost, use this equation provided by North American International Systems (NASI).

GR = gross yearly revenue
TH = total yearly business hours
I = percentage impact
H = number of hours of outage
Service costs are rarely zero.

Most businesses associate network downtime with major events or security breaches, but such isn’t always the case. Their own employees could induce it too. For many, that was the case every September. This blog is not about a challenge, but a growth hacking opportunity (transformed from an IT challenge).  Read More »

Secrets to Ensuring Application Performance at the Branch

Ensuring application experience at the branch is a daunting task. IT must look beyond traditional WAN challenges (like bandwidth, transport type, and speed) to applications experience. As time-to-market becomes a pillar of enterprise’s competitive advantages, application experience is key to ensuring fast service and high customer satisfaction.

In today’s connected world, users demand instant connectivity and seamless experience. As the business innovates, the burden on the WAN intensifies, yet three-fourth (75%) of today enterprises say their bandwidth budget will remain flat[1]. IT knows this, and they plan ahead. They evolve their network into a hybrid WAN (see Figure 1), utilize the latest technologies, but application performance still suffers. Why?

Video & Software Updates Don’t Need To Overwhelm Your Enterprise Network

Video growth is overwhelming the enterprise network

We have all been there. At work trying to watch the live company all-hands video, or the latest training, or perhaps even the latest YouTube video. But all we end up with are pixelated videos that take forever to start and constantly re-buffer. The workplace video experience can be abysmal if the WAN is not ready. Most of us will avoid a painful experience like that. Or, if we need to watch the content, suffer through it and spend extra time re-playing it until we can get the message. Talk about engaging employees and improving productivity! In all likelihood, at the same time, the IT team has been watching their network choke on all the additional video traffic. And as we all know we are just at the beginning of the video growth curve with HD everywhere, 4K, “engaging video training”, etc. Cisco, for example, forecasts that by 2018 IP video will represent 79 percent of all traffic globally.

Smarter Routers for the Intelligent WAN

New ISR 4K Routers!

New ISR 4K Routers!

I really don’t envy the Cisco ISR team. It is really tough to be a leader and still out perform yourselves on a consistent basis.  One could argue there is nowhere to go but down.  I think is cool that TechWiseTV has been around long enough to chronicle the changes over time.  Heck, many of our favorite engineers have been around the entire time as well..that gives us the unique ability to tell a story that can both respect and hopefully contrast the evolution in an appreciative way.

We recently had a chance to showcase the new ISR 4000 Series.  ISR remains the acronym for this family as it stands in for ‘Integrated Services Router.’  I am sure we made this argument before, but one way to characterize this one is to see just how much the innovation swings towards the ‘I’ and the ’S’ these days.  It makes sense. There is only so much one can do from a pure routing perspective, especially if you consider that speeds and feeds will grow naturally with the rest of the market and nobody pays the Cisco premium for just keeping up with the Joneses.

This new series is a compliment to the old family line referred to as the ISR G2. We covered that one back in 2009 with episode 53 ‘The Router is Dead. Long Live the Router.’  It is fun, for me anyway, to go back and see if my superlatives have gotten any less superlative.

Cloudburst: iOS 8 Generates 50% Increase in Network Traffic

Many network engineers recall the iOS7 update on September 18, 2013 as one of the most historic download days of their network’s history. All the more reason for us in the wireless world who anxiously anticipated the September 17 release of iOS8.

We asked a few of our customers to monitor the effect of the software release on their networks and the results for the first two days are in. Those in the education and healthcare space in particular are filled with early adopters of WiFi technology and devices, and eager to get their hands on the latest updates.

Joe Rogers, Associate Network Director at the University of South Florida shared this picture with us from 1pm September 17th, showing 1 Gbps more traffic than he would normally see at this time of day:


Another customer, Greg Sawyer, Manager of Infrastructure Services, shared this picture of the iOS8 effect on his network at the UNSW Australia.


He noted that his experience handling the release this year felt smoother than last year, despite the new peak internet download of 4.65 Gbps and 21Tb downloaded for the day! Not too surprising when considering that there were 27,000 concurrent connections on the wireless network and approximately 60% of those being Apple devices.

How should organizations be considering and handling these network spikes? I sat down with Cisco technical leaders Matt MacPherson and Chris Spain (@Spain_Chris) to get some insight on the effect of big updates like iOS8 on the wireless network. Here are some of the highlights of what we discussed:

The World We Live In

The truth is, more and more services are being moved to the cloud—a cloud that will push updates to millions & in the future billions of users and devices on our networks. Read More »
