Staring at the the hourglass

Posted by: Shamus McGillicuddy
It's the network, Network

Do you ever think about the time an end user spends staring at his or her computer while waiting for the network to process a request? It can be frustrating to watch that animated hourglass cursor every time you open up an application.

It might take just 15 or 20 seconds for a user too execute something in a networked application, but over the course of time all these little delays can really add up.

IT services company Dimension Data recently surveyed 957 knowledge workers and 267 IT decision makers around the world about network performance frustration. The firm found that the average user spend about two hours per month waiting for network-induced delays.

Those delays include

  • 35 minutes per month waiting for network logins.
  • 25 minutes per month waiting to access email.
  • 23 minutes per moth waiting for file transfers.

Think about this. Two hours per month adds up to one full day a year. Multiply that by 1,000 employees and your company could be losing tens of thousands of dollars per year in productivity.

Not only that, but users will be less likely to use certain applications that regularly experience network delays.. Then a company finds itself having invested thousands in a new application that no one wants to use.

And you think it’s hard to calculate ROI for investments in your network?

ElimiDate: Aruba, Meru come clean about acquisition dream dates

elimidate.jpgSo shockingly it’s not every WLAN vendor’s dream to be swept off their feet by a big, strong wired networking vendor. Some are pretty happy being independent! And they’ll even say that as rumors swirl around otherwise!

The Financial Times reported that Juniper was on the prowl for a WLAN counterpart, and named and unnamed analysts predicted Meru and Aruba were the likely targets.

Nonsense! blogged Chris Silva from Forrester. Juniper’s ready to acquire, but Aruba is too expensive, and Meru is kinda funny but who knows.

Well, Aruba e-mailed us back to make it fairly clear they’re not interested in Juniper, either. Maybe they’re playing hard to get? Maybe they’re protecting a tender heart? Who knows, but this is what Mike Tennefoss, Aruba’s head of strategic marketing, had to say:

As we enter the next wave of networking, an inflection point marked by the pending final ratification of 802.11n, innovative technology will be required to build converged security, mobility and wireless solutions. Aruba has assembled a world-class team focused on this objective, and we believe our work will be best accomplished as an independent company.

Before Juniper gets too heart-broken, though, they might still find a match. Minutes before calling it a night yesterday, I got a call on my cell phone from Rachna Ahlawat, Meru’s vice president of strategic marketing.

“There is enough going on and enough customers who believe in us and invest us to keep us busy,” she said.

That being said, how would Meru like to be swept of their feet?

“We are open to all different options as the company goes forward,” Rachna said. IPO or acquisition, it matters not, she said, because the company was not designed for one or another exit strategy.

So maybe Juniper does still have a shot at love after all.

Wall Street woes a problem for IT vendors

Posted by: Shamus McGillicuddy

The financial crisis that the United State is mired in is starting to feel like a never-ending earthquake. The ground is shaking beneath all of us and we’re wondering when it will end.

Watching Wall Street go into a meltdown is probably especially unnerving to the IT vendors who provide the infrastructure to companies that have ceased to exist, such as Lehman Brothers.

Bloomberg reported recently that IT spending by financial firms could decline by $4.3 billion next year, the lowest level since 2000. Does anyone remember the year 2000? That was the year the dot-com bubble burst, sending the IT sector into a long tailspin. Everyone has horror stories to tell about those years of companies closing their doors, IT pros losing their jobs and stock options going up in smoke.

The merger of Merrill Lynch and Bank of America alone will result in nearly $2 billion in IT spending cuts. Since that deal went down, JP Morgan Chase & Co. has bought out Washington Mutual and Citigroup bought out Wachovia’s banking operations, which will surely cut into tech spending in this market even further.

Some of the bigger vendors on the market should be able to weather this storm. According to Bloomberg, Cisco System derives just 3% of its revenue from the financial sector. Other smaller vendors are probably more exposed than that. Now more than ever, when shopping for new technology or managing existing vendors, it’s important to know how financially sound they are.

Aruba to Customers: Get 200% more WLAN bandwidth, free!

Posted by: Michael Morisy

Claymation Christmas
Christmas is coming a little early this year (don’t you hate how it creeps up on you?) for Aruba customers. The WLAN equipment company announced the availability of their Adaptive Radio Management (ARM) 2.0 controller software, which can give Aruba mixed-mode Wi-Fi networks a significant boost by better optimizing how and when data is sent. In some tests conducted by Craig Mathias at the Farpoint Group, total throughput was up by as much as 200% in some scenarios (being vendor sponsored and all, take these “ideal scenarios” with a grain of salt).

The update is free to customers with existing support contracts, and also includes improvements on how the network handles “chattery” clients and how it deals with co-channel interference.

Overheard @ Interop NYC 2008: When high fashion and high tech collide

Posted by: Michael Morisy
BlackBerry, Cisco, Interop, Network

Vendor A: “Busy enough for you?”
Vendor B: “Packed in here.”
–Two empty vendor booths

There’s nothing quite like Vegas, I was told, right before tromping off to Interop New York, and boy were they right. No MacGyver. No high-stakes (or low-stakes, for that matter) poker with the stars. And really, not many announcements. As Rivka Little blogged, going there made you wonder if trade shows are dead, although the Fashion Coterie trade show right next door seemed to be booming (with better swag, too!).

Strangely, one of the biggest presences was RIM, pushing their PBX interoperability as well as showing off some shiny new Bolds. I have to admit, seeing them In Real Life really made me appreciate the upgrade in screen quality over their predecessors. We watched some movie trailers, and I was surprised that they were actually watchable as opposed to the almost farcical activity of watching video on a Curve.

RIM also had David Yach, their CTO of software, give an Interop keynote and lined him up for a series of interviews about the future and philosophy of BlackBerry software.

Cisco, it seems, isn’t quite so enthusiastic, as Rivka quoted one Cisco exec: “We don’t do these tradeshows the way we used to. Cisco does a lot of it virtually now. And we use our own technology like telepresence to meet with people. Folks are crunched to travel.”

And the ones that do make it there? Occasionally sidelined.

Security: What does your company make?
Cisco Executive: EVERYTHING.
–Outside Fashion Coterie trade show floor

The feelings, alas, were not mutual.

Clacker: Oh my God, we missed it!
Fashionista: What are you talking about?
Clacker (with growing horror): We missed the show! These guys are definitely not in fashion!
–Outside of Interop trade show floor

Arrgh! Acquisitions and attacks on the high (tech) seas

Our SearchNetworking Talk Like a Pirate Day cake.

Ahoy! Just in time for our Talk like a Pirate Day blog post (what’s a weekend late among old salts?), we hear tales of treachery and triumph, of bold moves and dastardly deeds.

First, matey, is the tale of Cisco’s Jabber acquisition. Why would the world’s dominant networking gear provider buy a second-tier IM platform? While you may not actually know anyone who uses Jabber, the Extensible Messaging and Presence Protocol (XMPP) Jabber is based on has seen quite a few fans, not the least of which is Google which has embraced the protocol for its Google Talk instant messaging platform.

As Cisco continues to make good on their promise to put structure behind Web 2.0-type tools, Jabber is a good place to start: A widely accepted IM standard heartily approved by the geek crowd which also gives enterprises the control they want. And some are also seeing it as a shot against frenemies Google and Microsoft, like the National Business Review’s summary:

IM gains more respectability with the announcement over the weekend that networking giant Cisco will buy Jabber, whose software allows users of rival freebie IM programmes, such as Apple’s iChat, Google’s Talk, Microsoft Windows Messenger and Yahoo Messenger, to interact with each other, plus send messages to commercial grade programmes such as Microsoft’s Office Communications Server.

The article title was even more direct: Cisco guns for Google, Microsoft with Jabber buy.

On a more swashbuckling note, Aruba’s taking aim at Motorola, counter-suing the company for patent infringement:

“The first asserted patent was assumed by Aruba in March 2008 as part of its acquisition of AirWave Wireless Inc., while the second asserted patent was issued to Aruba in May 2008,” the company said, adding that it is seeking a permanent injunction against use of its patented technologies as well as monetary damages.

The WLAN market is treacherous waters, as we’ve reported before, so we don’t expect this back and forth end until one or the other goes to Davy Jones locker.

IPMan fights Jitter in latest tech-themed webcomic

Posted by: 2020viip
Broadvox, Cartoon, IT humor, VoIP

This week at ITExpo West 2008, SIP trunking providor Broadvox debuted their addition to the world of IT-themed webcomics: Adventures of IPMan.


According to Broadvox’s press release, “IP Man and [his sidekick] Metoo were conceived to captivate and entertain telephony experts while they battle the enemies of IP Communications: the evil Mr. Bellhead, Noise, Jitter and Echo.”

While the three episodes of the comic available on the IPMan website are all obvious pitches for Broadvox, there is a pretty amusing Space Invaders-style game (dubbed “Tele-vaders”) — and episode two of the comic strip, especially if read aloud, offers several opportunities for Michael Scott-esque “that’s what she said” quips.

But it’s not all fun and games — if your boss walks by, you can quickly navigate to the “shields” page and read about fundamentals of IP service delivery, such as QoS and network reliability.

Riverbed spills into storage market

Posted by: Tessa Parmenter
Networking, Storage, Virtualization, WAN optimization

Riverbed, a well-known vendor in the WAN optimization space, is now expanding their product line to include a new storage optimization appliance called Atlas — which will place them as a strong contender in the storage market space. Although the product is not set to launch until the beginning of next year, it is said to revolutionize data storage by applying some of its WAN optimization tricks to the server.

How will Atlas put them on the map? The concept of the technology is as VP of Product Marketing Alan Saldich says: “It’s almost like virtualizing data.”

For those unfamiliar with their typical WAN optimization deployment, steelhead appliances are applied to either side of a WAN link to conduct deduplication in storage file servers. But Riverbed’s Atlas steelhead appliances will break files down into bits, and send only information to the server that hasn’t been seen before.

“The Atlas appliance is very much like [an] indexer. It doesn’t hold the information; it holds pointers to where that information is stored,” says Saldich.

Since so much of back-up data is duplicated, Riverbed finds their method would potentially save as much as 80% of storage space in file servers.

What does this mean for their WAN optimization products? Although some may see this product announcement as a way for Riverbed to drift away from their original market, they are merely diversifying their portfolio. PR rep Nicole Schlossberg says Riverbed is not leaving the WAN optimization space. Atlas is an addition to the product line.”

The line between network and storage markets is too permeable for a vendor to see them as two separate spaces. It makes sense that a WAN optimization vendor could also optimize your storage. And though the marketplace has dissolved the line between these two siloed groups, the workforce hasn’t moved its IT structure to adapt.

A Shot at Love with Juniper Networks?

Posted by: Michael Morisy

Will Aruba pick him?

When it comes to enterprise Wi-Fi, the industry’s got enough drama for an MTV reality series, with constant bickering over what WLAN architecture’s better, or which .11n product truly supports PoE, or which skeezy AP went home with a stranger last night.

All this is to say it’s not surprising there’s a lot of back and forth about a rumored Juniper acquisition of Aruba or Meru. reported that two analysts and another source think a Juniper purchase is looming, and these two are the likely targets.

Chris Silva, Forrester analyst, had his own theory: Juniper, indeed, was ready to bite, but Aruba is too expensive and Meru might be too weird:

So, there it is, I’m drawing a line in the sand that the acquisition target is not Aruba, perhaps Meru and potentially another, even smaller vendor. Nothing short of hedging on my part, I suppose, but I will say this: WLAN is a logical line extension for Juniper, and I’m not ruling out – but rather expecting – at least one more acuqisition before the year is out.

We followed up with Chris to name names, and he kindly got back to us.

“It’s a tough call,” he e-mailed. “Bluesocket seems to be one of the last men standing. Aerohive is too small and too new and Extricom, while likely a cheaper buy than Meru, is the same technology without the customer list.”

Aruba, however, doesn’t seem to be sitting at home waiting for Juniper’s phone call. They’ve teamed up with Foundry to form a “co-marketing relationship between the companies’ wired and wireless LAN products for Federal customers.” A small step for LAN, to be sure, but maybe signaling a future giant leap (acquisition?) for LAN-kind?

Straight from Aruba’s announcement of the “relationship”:

“This collaboration affords Aruba and Foundry the opportunity to target a sizable Federal market in need of new and replacement secure networking infrastructure,” said Keerti Melkote, Aruba’s co-founder and chief technology officer. “We have steadily enhanced our suite of wired products, including wired remote networking technology, to complement our industry-leading wireless LANs. As Foundry’s first wireless LAN vendor to be designated an Ironpowered Technology Partner, we’re now in a unique position to co-market our products, together with Foundry switches and routers, across a broad range of Federal applications.”

Sounds awfully cuddly to me.
