SMB technology: Replacing in-house software with applications in the cloud
In the near future, there's only one way to go for SMBs when it comes to purchasing business software -- and that's out of house. Whether it's full-on SaaS (software as a service), where users access all facets of the application through a browser, or a hosted product (including hosted Exchange, where only the server component is off-site and users employ a standard desktop client such as Outlook), either model is simply too cost-effective for SMBs to ignore.

Processors: Dividing chips into many virtual cores
The current approach taken by x86 CPUs -- to stuff as many processor cores and as much cache memory as will fit on one chip -- will prove impossible to scale beyond a certain point. And adding more, big, hot processor cores may not be the best fit for server roles that call for managing large workloads over long periods of time.

Hunting down dark fiber
The speed of optical-grade broadband is beginning to reach our homes, at least those lucky enough to live in areas covered by Verizon's FiOS (fiber-optic service) or similar offerings.

iPhones flooding wireless LAN at Duke University
The Wi-Fi connection on Apple's recently released iPhone seems to be the source of a big headache for network administrators at Duke University.

Silver Peak hits new WAN-optimization heights
You know what makes network administrators happy? Making efficient use of their equipment and eliminating "performance stinks" calls from end-users. Thus, investing in an effective WAN optimization and acceleration solution such as Silver Peak NX-5500 2.0 can put a big smile on your network admin's face.

Silver Peak Systems: Transforming WANs into LANs
You wouldn't accuse any segment of the high-tech sector of orthodoxy. But even by tech industry standards, the market for WAN acceleration is a wild ride. Just ask Silver Peak Systems' founder and CTO, David Hughes, who says that in the WAN space, sometimes "no" means "yes," late is better than early, and you have to add to subtract.

Do-it-yourself content distribution
Content delivery networks make a lot of sense if you need to accelerate the delivery of video, content, and applications over the public Internet, but what about internal corporate WANs? “CDNs and ADNs are for folks who need to leverage the Internet as a business-grade network,” says Robert Whitely, senior analyst, enterprise networking, at Forrester Research. “For private networks using frame relay, MPLS [multiprotocol label switching], or an IPSec intranet, where one company owns both ends of the network connection, appliance- and/or software-based approaches to WAN optimization may be the answer.”(Read also about content distribution networks in Your Web site’s secret weapon.)

Meanwhile, your resources are stretched tighter than a $2 string on a banjo and you spend so much time putting out fires you should be wearing a helmet and carrying a hose.

Packeteer iShared yields mixed WAN optimization results
Poorly performing WAN links continue to be the bane of many network administrators. Wherever there is a WAN link, there will be performance degradation caused by latency and chatty protocols. Simply adding bandwidth is not the answer. Using appliance-based solutions on each end of the WAN circuit, however, can improve overall response time and throughput.

2006 Year in Reviews: Networking
After most of the vendors declined our invitation to a WAN shootout last year, we settled for a series of standalone reviews of WAN accelerators this year. As usual, Riverbed’s Steelhead shined -- so did products from Silver Peak, Blue Coat, and Cisco Systems, though they still swam in Steelhead’s wake. Perhaps competition will be stiff enough for a comparative test in 2007. Stay tuned.

Exclusive: WAN optimization, the Cisco WAE
As the enterprise becomes more dispersed and applications continue to greedily gobble up precious WAN bandwidth, IT struggles to find ways to coax just a little more performance out of its existing circuits. All of the bandwidth in the world won’t reduce application response times as long as TCP and latency remain tightly bound together. In order to improve WAN performance, it takes digital sleight of hand to work a little WAN magic.

Juniper unveils branch-office strategy
Enterprises have done wonders in recent years consolidating their IT operations into efficient and tightly managed datacenters. That trend has been a godsend for system administrators and IT workers, who no longer have to spend long hours on the road, in transit to far-flung branch offices to reboot servers and take care of other mundane tasks. One population that hasn’t benefitted from centralized IT operations: the poor souls who have to work in those branch offices and live at the mercy of their WAN connection. And that’s no small population. By one estimate, as much as 80 percent of employees at many companies now work outside of headquarters.

Riverbed Steelhead boosts WAN data flow
IT always seems to be caught in the middle of the WAN-performance battle: On one hand, users never seem to be happy with an application’s performance; on the other, the bean counters won’t budget for bigger pipes. If more bandwidth isn’t the answer to end-users’ performance problems, then what is?

China and India to drive WAN growth
A stable economic and political climate and foreign direct investment could drive the implementation of WANs (Wide Area Networks) throughout Asia, especially in China and India, a research report said Thursday.

Blue Coat Systems’ SG line of WAN accelerators builds on traditional WAN optimization methods by adding a couple of their own, including support for SSL encrypted traffic and streaming media. Based on a series of protocol- and application-specific proxies, the SG appliances balance flexibility and performance with ease of use, and they support basic bandwidth management and content filtering.

Franchising the energy web
I’m already so depressed about the sorry state of our planet’s energy systems that I’m afraid Al Gore’s An Inconvenient Truth would just send me over the edge. Oh, I’ll probably relent and go see the movie, but in my case the ex-Veep will be preaching to the choir. I don’t need to be convinced any more than I already am that we’re in for a rough ride. What I need, instead, are hopeful signs that we’ll be able to engineer our way out of the mess we’re in.

US gov't telecommuters hit roadblocks

Slow progress for 802.11n standards
The IEEE 802.11n standard has been three years in the making, and from the looks of it, it has at least another year to go. That’s a shame because it offers a lot of benefits, including higher throughput than the current Wi-Fi standard -- about 120Mbps in the real world -- and 50 percent longer range. Plus, because it uses multiple antennas that can stitch together a fractured signal, it eliminates a lot of spots where there might be drop-offs indoors.

InfoWorld CTO 25
The top technology slot in the enterprise has changed. Once, forward-looking CTOs and CIOs scanned the horizon for new technologies that would improve the lot of IT. Today, as many of this year’s top 25 CTOs can tell you, technology leaders must also focus on understanding the business goals of the enterprise -- and then craft technology strategies to meet those objectives.

Hack Tales: Keeping thin clients synced from coast to coast
I once consulted for a medical-records company that was rolling out thin clients to nearly 50 offices around the United States. The goal was to build a large Citrix MetaFrame farm over WAN links to the main datacenter, which was located outside Boston, providing a Windows desktop for every user without dealing with hardware problems at each site.

Interop shows slow, steady progress on NAC
Network access control was a hot topic at last year’s Interop show, despite an evolutionary state that was barely protozoic. But new developments from the Trusted Computing Group (TCG) and pure-play vendors such as Vernier and InfoExpress could soon enable the technology to crawl out of the muck and take its place on enterprise networks, according to one expert.

NX-3500 pushes your WAN to peak performance
You can always pick out the IT heroes: They’re the ones that keep their users happy -- and productive. Sometimes that’s hard to do when the users have to access applications and data on the other side of an oversubscribed WAN link. It isn’t just a bandwidth issue; a big pipe isn’t always a fast pipe. Users need a reduction in latency and protocol chattiness coupled with TCP optimization and intelligent caching. They need a WAN acceleration and optimization solution.
