WAN Optimization Reinvents Itself

WAN optimization has been around for years, but where it was initially developed to improve the performance of applications accessed across a wide area network (WAN), primarily from the data center to branch or remote offices, increasingly it is showing up in data center-to-data center applications. And what was once largely a market dominated by […]

Serenity Now!

One of my favorite Seinfeld episodes is the one in which Frank Costanza yells, “Serenity Now!” every time his blood pressure was in danger of rising. Clearly, he was using this “technique” to relieve his stress. Unfortunately, Frank’s method of relaxation drove everyone else crazy. While data centers and WAN infrastructures continue to grow in […]

Clogged Network Pipes Got You Down?

When networks become congested with bandwidth-hungry applications and inefficient network technologies, it can resemble your typical home plumbing nightmare – backed-up, corroded piping sending murky, slow-moving water into your waiting basin. Not exactly the refreshing splash you were anticipating. Fortunately, when my water pipes are congested because of corrosion from rust and mineral deposits, or […]

Why My Mama Runs Faster Than Your App

You know the drill. The request comes down to run XYZ app between offices. You run it on the LAN and, of course it all looks fine, but when you put it on the WAN, performance drops about as fast Rich Eisen on the 40.  Now you need to explain the problem to your users […]

WAN Optimization is the MVP of the Game

I realize it’s only Spring, but it’s hard not to talk about football when you’ve got all kinds of NFL news breaking, like New Orleans Saints’ coach Sean Payton getting suspended, Tim Tebow going to the Jets and can’t-miss, future Hall of Famer Peyton Manning going to the best team in the league (selfish disclaimer: […]

Caution: Merging Traffic Ahead

I dread merging traffic signs. We all know what happens when the road we’re merging with another road: traffic congestion. It’s logical, right? When 30 cars on one road converge with 50 cars from another, a backup is eminent. (The 101 and 280 interchange in the Bay Area is a perfect example.) Network traffic experiences […]

Look! On the Internet! It’s a Phone! It’s an iPad! It’s a Laptop!

No… It’s all of them! OK, the title is a poor attempt to play off the Superman theme. Hopefully, it was enough to get your attention. And it is relevant for today’s network computing environment for virtually any enterprise. Not only are employees accessing applications and downloading files from these devices and others, they are […]

Optimizing Satellite WANs for Armed Forces in Afghanistan

Global telecom service providers that rely on satellite wide area networks (WANs) face challenges from high-latency and packet errors.  Telecommunications provider Carrier to Carrier Telecom B.V. (C2C) faced these problems while providing satellite connectivity services to various armed forces in Afghanistan.  C2C found the solution with Silver Peak virtual WAN optimizers, and now benefits from […]

March Doesn’t Need to Make WAN Admins Go Mad

Before I begin this post, full disclosure: I graduated from Duke University. So, when it came to writing about March Madness, I was the first to volunteer. I am also one of the biggest culprits that Colin Neagle (@colinneagle) refers to in his recent Network World article, “Controlling your March Madness Traffic Outbreak.” While I […]

You Can’t Squeeze Blood Out of a Turnip

They say you can’t squeeze blood out of a turnip. And if you could, why would you? However, you can squeeze more bandwidth into your network. And by doing so, you can support more users and applications, and gain more throughput for faster delivery of applications. With the abundance of IP-enabled devices and converged networks, […]
