In 1979 The Buggles released their debut single, 'Video Killed The Radio Star,' a nostalgic look at radio from the perspective of the video age that killed it.Progress drives on, looking nostalgically in the rear view mirror from time to time, but propelled forward by the engine of our insatiable desire for something better.Tube-based table radios are nostalgic. So are rotary phones, wooden plows, and iron clad ships. Doesn't mean we want to use them anymore. They were abandoned because something better came along. Something easier to use. Faster.Less expensive.
Technology transitions happen all the time in enterprise IT, but the branch office and fixed teleworker seem to have been neglected along the way. And what an oversight it was. Today more than 85% of employees work outside of the primary corporate campus. Yet they need - but haven't had - the same access to corporate network resources and applications as someone in the home office.
The solution cobbled together by router vendors was to remotely replicate the infrastructure that's on the corporate campus. That is, assemble a stack of appliances for security, VPN, Wi-Fi, routing - and then try to integrate them to work together.Over time the separate appliances morphed into an integrated branch-in-a-box router. But experience showed that while you can morph a router from a hairball, but you can never take the hairball out of the router. From the user's point of view, the solution was little improved.
The fundamental problem is that the campus network and its branch offspring were designed assuming static users sitting behind protective firewalls. Mobility - mobile users specifically - breaks that model. You have to punch holes in firewalls, configure complex VLAN assignments for segmenting traffic and user types, install VPNs to protect roaming users. The list goes on and on. And grows more expensive, complex, and user unfriendly as it does.
Virtual Branch Networking (VBN) 1.0 was introduced in 2009 as a ground-up, mobility focused solution. VBN made it less expensive and simpler to securely connect remote users with the enterprise network at low cost and without changing the user experience.
VBN 2.0 goes one giant step farther by leveraging cloud services to do the job done by branch routers today - application acceleration, content security, remote access. Only it does so using a lower cost, more scalable solution that delivers a consistent user experience regardless of where you work: in the corporate HQ, in a branch office, from home, or on the road.
The cloud provides a massively scalable, economical way of delivering services and applications. It has changed the way we transfer data, download files, and use applications. When applied to branch networks, cloud services are the perfect tonic. They deliver essential business-critical services, without complexity, to widely distributed users at less than half the cost of the branch in-a-box router. This is one change you'll make and never, ever look back.
In my mind and in my branch,
We can't rewind it bought the ranch,
VBN killed the branch-in-a-box.

Time was when you left work at the office. Those days are long gone. Enterprises and institutions with workforces, offices, or colleagues spread across time zones often have time- and location-shifted working conditions.
Users might need to work from home, on the road, or at a remote site. In all cases, a user will be most productive if the network experience - and access to applications and network resources - is the same remotely as it is at his or her desk at work.Can the wireless LAN infrastructure that's used in a campus environment pull double duty and be used by remote users, too? The stock answer from most vendors is "nary the twain shall meet" - use a campus wireless LAN at work and a remote access solution like a virtual private network (VPN) everywhere else.
Since using a VPN is very different than accessing a campus network, this means that users need to be trained how and when to use the appropriate access method. And that means Help Desk calls. The end user is stuck with two parallel, non-intersecting networks to buy, maintain, and learn. Ouch!
The Lessons of Wi-Fi #12: your Wi-Fi network should not be a one-trick pony. One common network infrastructure should support both the campus wireless LAN and off-site users. And it should provide an identical end user experience regardless of how or where the network is accessed.
Enter Aruba's Virtual Branch Networking (VBN) technology. VBN uses low-cost Remote Access Points (RAPs) to securely connect remote users, and their Wi-Fi and wired Ethernet devices, back to a controller in the data center. The same controller that runs the campus Wi-Fi network.
Any standard Aruba indoor access point can be used as a RAP. That means one SKU can serve as both a campus AP or a Wi-Fi enabled remote access device for a home, branch office, or road warrior.
The $99 list price RAP-2 unit pictured here is small enough to fit in a shirt pocket or valise. It works with any IP-based devices - laptops, iPhone, iTouch, PCs, printers, wired and wireless voice over IP phones, wireless projectors - all of which can simultaneously share a single RAP. As can multiple users.
VBN features one-button installation so that a non-technical person can provision a RAP-2 by him or herself. No IT assistance, no user training required. Once commissioned the user just turns on his or her MacBook, PC, iTouch and they're instantly connected to the network...just as they would be on campus.
Data encryption and an integrated firewall provide comprehensive network security for all RAPs, while centralized management ensures speedy diagnostics and updates right over the network.You don't have to suffer a double budget hit to get best-in-class campus Wi-Fi and secure remote access. So check out VBN and leave it to someone else to relearn the lessons of Wi-Fi.
One of the challenges of distance learning is how to replicate the "campus experience" for remote students. Doing so encourages collaboration with other students, and improves study opportunities, by leveraging the same electronic learning applications, library reference materials, and server resources as campus students enjoy.
It also builds school loyalty because if these services remain in place post graduation, it improves the chances of continued participation once students become alumni.
Providing secure access to your school's electronic learning resources is a challenge. Open access or password-controlled access won't protect against network attacks, password-sharing, or excessive bandwidth consumption by mischievous students.
A secure virtual private network (VPN) requires your IT staff to load and manage client software on every device a student might wish to use. This is an on-going burden because incompatibilities may be introduced as students upgrade operating systems or other applications on their computers.
Virtual Branching Networking (VBN) solves distance learning connectivity and security issues. Using a small, very inexpensive device called a Remote Access Point (RAP), VBN enables remote students to connect securely to your data network. RAPs enable students to use any IP-based devices with an Ethernet port or W-Fi - MacBooks, iPhones, iTouches, iPads, PCs, VoIP phones, printers - without loading any software clients.
A built-in firewall strictly enforces access policies set by your IT staff, and can even control how much bandwidth a student uses. All access policies are centrally managed and then pushed over the network to the RAPs. The same is true of software updates: they're pushed automatically to every RAP in the field.
New RAPs are shipped unconfigured. To connect one to your network the student pushes a button on the front of the unit and then enters the IP address of your data center.
A RAP controller in your data center then exchanges security certificates with the student's RAP and voila, the student is on-line. No IT staff involvement is required for this process to occur, meaning that it's possible to economically support a very large distance learning program without adding IT staff.
Since RAPs are shipped unconfigured, they can be sold or rented to students through your bookstore or by a third party with zero-touch involvement by your IT staff. If a student leaves your distance learning program, or fails to pay tuition, a simple change in the access policy will completely disable the RAP.
Alternately, when a student graduates the RAP settings can be changed to disable distance learning and enable Internet access using your alumni site as the home page.
VBN has been field-proven in enterprise teleworker deployments around the world, and is the ideal solution for distance learning applications of any size. To find out more please visit our Web site.
A funny thing happened while Aruba was on the way to market with its innovative Virtual Branch Network (VBN) solution and "network rightsizing" initiative - Cisco got hot and bothered. Just after the VBN solution received the 2009 Best of Interop Las Vegas Award in the Wireless & Mobility category (http://bit.ly/aUocV), Joel Conover, senior manager, network systems at Cisco called the new 600 Series Branch Office Controller "a travesty" (http://bit.ly/KOmNv). He then claimed that Cisco offered the same capabilities with a new product...but only when used behind an expensive Cisco 800 Series ISR Router. Why does Cisco need an expensive WAN router when Aruba VBN does not, even for the entry level $99 list RAP-2?Aruba's rightsizing initiative promotes the use of Wi-Fi everywhere it can be used, wired networks only where they must be used. Rightsizing is a three step process whereby users assess current wired LAN utilization using a tool like StatSeeker (on average 30-40% of wired ports aren't used at all), consolidate switches and scale service plans/cooling/power consumption to match, and then invest the savings in upgrading the Wi-Fi network to 802.11n. Simple and logical, right? If you can save money you should. If your network is already rightsizied then the most you've invested is some time verifying that's the case.Customer reaction to rightsizing has been nothing short of amazing. The California State University System identified $30M of savings by shifting from wired networks to Wi-Fi (http://bit.ly/uvjbu). Cisco, however, had a different reaction.When John Cox published an article in Network World titled "Is it time to cut the Ethernet access cable?" (http://bit.ly/3cG4t) in which he noted that pervasive WLANs leave costly wired ports idle, Cisco flipped. Chris Kozup, ironically titled senior manager for mobility solutions at Cisco, maintained that an Ethernet cable is exactly what everyone needs. Aruba's right-sizing is a "shortsighted message from a wireless-only provider. It's penny-wise and pound-foolish." Using Wi-Fi as the primary form of network access is inflexible and the benefits exaggerated, he said. And yet....Cisco itself released a report stating that its own employees average 90 minutes per day of additional productive time using Wi-Fi (http://bit.ly/UNHQd). So why is Cisco so aggressively pushing wired LANs on customers? The answer to both questions can be found in Cisco's business model, which depends on profits generated from selling overpriced wired routers and wired ports. The big R&D bucks go to the wired side of the house, which is perhaps one reason why Cisco's lackluster wireless LANs are missing innovative features like application awareness and adaptive response to changes in local RF conditions. Cisco's focus on wired LANs and lack of wireless innovation has resulted in two consistent forms of behavior: attempts to replicate features found in Aruba's innovative products (Cisco's new band steering feature and the changes in their newest network management console appear to be almost exact replicas of Aruba features); and whining, as exemplified in the articles above.If you want real innovation, look to companies that identify problems and deliver creative solutions. Replicators and whiners need not apply.
