Aerohive – Wireless Lan

authorized_partner_logo1Aerohive Networks, the award-winning creators of the controller-less “cooperative control” wireless LAN (WLAN) architecture, today announced the introduction of Dynamic Airtime Scheduling. Dynamic Airtime Scheduling dramatically improves wireless LAN performance by measuring each client’s instantaneous data rate and airtime use and scheduling airtime based on IT-specified policies. It can be used to ensure that fast clients, such as 802.11n clients, aren’t slowed down by lower-speed clients, and it can enforce IT-specified policies to ensure that critical applications and users receive adequate airtime. Dynamic Airtime Scheduling provides greater system capacity in busy wireless networks and can increase individual clients’ performance ten-fold.

Unlocking the Full Value of 802.11n
On wireless LANs, only one network client may transmit data at a time. Traditionally, faster clients must wait while slower clients take their (relatively long) turns. Clients can be slow for many reasons, including lower-speed protocols (i.e., 802.11a), wireless interference, inconsistent RF coverage, and distant or obstructed network connections. On the vast majority of wireless LANs, there are slow clients that significantly degrade the performance of all clients. These factors prevent many enterprises from realizing the full value of their 802.11n investments, because their 802.11n clients operate far below their maximum data rates. Airtime Scheduling enables faster clients, such as 802.11n clients, to complete their transmissions without waiting for the slower clients to complete theirs, unlocking the performance potential of the faster clients without penalizing the slower clients.

“In wireless LANs, the worst client dominates the air, as only one client can transmit or receive at a time, and slower clients take more airtime to send the same data,” said Adam Conway, vice president, product management, Aerohive Networks. “Aerohive’s breakthrough Dynamic Airtime Scheduling technology resolves this issue, creating dramatic performance improvements in a wide array of common, yet challenging, wireless LAN environments.”

Dynamic Airtime Scheduling Provides Superior Scheduling
Because Dynamic Airtime Scheduling measures the actual airtime of each client’s packets, it delivers better performance improvements than protocol-based scheduling approaches that simplistically prioritize 802.11n clients over 802.11ag clients. Protocol-based scheduling does not address the issue of slow 802.11n clients impacting faster 802.11n clients, nor does it prevent slow 802.11n clients from restricting faster 802.11ag clients. In fact, protocol-based scheduling can inadvertently prioritize slow 802.11n clients at the expense of faster-performing 802.11ag clients.

“A fast radio isn’t sufficient by itself to produce great performance in large-scale production WLAN environments,” said Craig Mathias, principal, Farpoint Group, a wireless and mobile advisory firm. “As we’ve seen over the years with operating systems, how traffic is scheduled, along with QoS management, can make a huge difference in how well a WLAN system actually succeeds. Aerohive’s Dynamic Airtime Scheduling is a great step forward in assuring that mission-critical Wi-Fi installations provide the best possible service to users and their applications alike.”

Aerohive Architecture Enables Microsecond Feedback
Aerohive’s unique cooperative control architecture features a distributed control plane, which puts control and data intelligence in the HiveAP along with the radio, creating a microsecond-feedback air interface that is able to react to instantaneous changes in the RF network, such as clients changing their data rates.

Other New Features
Dynamic Airtime Scheduling is delivered in HiveOS 3.2, the latest version of Aerohive’s HiveAP operating system software. HiveOS 3.2 is a substantial release, with 20 other new features that are focused on application support, resiliency, and management, including firewall enhancements and Track IP path resilience.

A significant new feature of the latest HiveOS release is HiveUI, an easy-to-use embedded network management application that can quickly deploy a hive of up to 12 HiveAPs. An entire hive can be managed via the HiveUI Web interface on a single 802.11n HiveAP, providing configuration, status, and guest-management functionality to customers who do not require the advanced features of Aerohive’s HiveManager network management system. This free, intuitive interface reduces the cost of and simplifies small deployments, extending the benefits of Aerohive’s cooperative control architecture to smaller businesses.

Web 2.0 and Convergence

What does Web2.0 really mean? Will it really have any impact on my business?, Can it save me money? Will it cost me money? Will it mean my employees spend all day on facebook!! and the list can go on and on.

We are entering an age of true mass collaboration, where knowledge becomes shared, the wisdom of the crowds, information ownership becomes blurred, intellectual property is put on-line in order to realise new value, and social and professional networks become converged. Got a question post it, google it, blog it, twitter it, wiki it, there will be an answer out there somewhere. Is it the right answer you make up your own mind or you run it past a social or professional friend.

All this relies on the always on, always available networks. Next generation networks need to have increased availability, be secure, be scalable, and be simple to manage. If you are running a network do you truly know what applications are running over your network, consuming your bandwidth, or exposing security vulnerabilities? With business resources – your employees, consisting of digital immigrants and digital natives,  all require access to social and professional networks. It’s not just as simple as securing your network by switching off a few selected apps like MSN and Skype, this approach can have an adverse affect to employee productivity, in the digital age, ad-hoc collaborative project groups are being established using this technology which in true terms provide benefits to the business.

HOW CAN WE HELP – We spend a lot of our time finding innovative products to build the next generation of networks for our customers/partners. These solutions can reduce operational costs while providing the functionality that the next generation of enterprise MUST have in order to support new business opportunities and challanges.

If you are looking at reducing op-ex, supporting new technologies, have concerns on security – we may have an answer for you. Our solutions portfolio starts at the network core with;

1) Bonded 3G fail over solutions so you still have connectivity if your hard wired WAN link fails or for remote/mobile requirements.

2) UTM – Unified threat management – this includes FIREWALL, Antivirus/Antispam, Database security, Intrusion Prevention, Web App security, endpoint security.

3) High availability switch and routing networks – with VPN and QoS (Quality of Service) key to ensuring scalability and functionaility for real time services. (I-Phone and the next generation of devices will  be a significant driver for this) – as seen with the development of app’s for the likes of software as a service solution providers like salesforce.com. These applications on mobile devices give availability of valuable information anywhere, anytime increasing productivity.

4) Edge/Access network – more and more edge connectivity will be through wireless technologies for true available anywhere access. Wireless networks most importantly need to be secure – 802.11i(WPA2), Wireless IDS, 802.11X authentication, rogue detection, integrated stateful firewall and guest access control are all key considerations. This combined with the 802.11n capability of the Aerohive wireless access points offers the requirements to bring this function to company networks now. This combined with the mesh connectivity, dynamic airtime scheduling and controller-less management offers a enterprise class solution with considerable savings over existing vendor solutions.

All this comes at a time where organisation have significant pressures on their IT budgets. Typically the 80/20 rule applies with 80% of IT budgets spent on operating the network (OPEX) leaving only 20% available for new products and technologies (CAPEX). This is forcing IT departments to remain the status quo and rather than embrace the new technologies and applications their answer is to limit traffic across the network so as to reduce bottle necks due to limited network capacity, BLOCK new applications which drive up bandwidth, and delay implementation of new wireless connectivity solutions.

Where as if you embrace the new technologies – save op-ex through reduced power, cooling and real estate costs, re-invest this in new technologies through virtualisation, lower power, higher capacity switches, Unified Threat Management (security) – the days of per seat security pricing are gone, and simplify employee and guest access to your network. This with reliable power infrastructure (UPS, DC and HVAC) will enable your business to seize the next generation of technologies, have a collaborative, knowledgeable and productive work force and an organisation that is adaptable and responsive to change.

If any of this has sent the synaptac connections in the brain twitching, neurons firing, you feel like twittering, need some advice on what it all means, you are just plain confused, or if you feel the need to get on the immigration path to the digital highway let us know we will be more than happy to support/advise/deploy or manage.
