Last week, our leaders in the education market held a webinar on network scaling – the first of the series of 3 webinars that discuss the top challenges facing K-12. In the webinar, they discussed best practices to handle growth, BYOD, and new instructional technology and applications. They provided information on key wireless and wired technologies and device on-boarding and management for scale. They shared lessons from K-12 district peers.



Higher-Education Networks have reached a tipping point where traditional enterprise networks with Gigabit uplinks are struggling to keep up with students and researchers’ relentless demand for seamless mobility, access to the latest generation applications and research staff’s needs for more bandwidth. In addition, Higher-Ed IT departments are increasingly challenged by the exponential increase in the volume of research data and the proliferation of areas on the campus where the data is generated, lives and needs to be shared.  Challenges include:


  • University researchers need to move very large datasets across the network: In the areas of medical research, genomics and climatology to name a few, datasets are becoming excessively large. For instance, genome sampling generates datasets that can represent multiple hundreds of gigabytes per genome. Medical imaging also produces gigabyte size files as well that need to be transferred to storage. The equipment that produces these large datasets is proliferating in labs across the campus that are connected to the edge of the network. This creates the need for high performance and high capacity switches to be deployed at the network access layer and little to no oversubscription between the network access, aggregation and core layers.

We are happy to announce support of Ruckus APs and controllers in our network management tool – Brocade Network Advisor.


Campus networking has reached a tipping point where legacy Ethernet networks with Gigabit uplinks are struggling to keep up with users’ relentless demands for seamless mobility access to the latest generation applications. IT departments are increasingly challenged to maintain network SLAs on outdated equipment across the campus.


  • Mobility is now ubiquitous: Legacy campus networks are struggling to keep up with the large amount of traffic generated by an ever increasing number of Mobile users connected to the latest generation 802.11ac Wave 1 and the new 802.11ac Wave 2 WI-FI access points.
  • Video Streaming is taxing the network: Video streaming, video conferencing and video surveillance consume a mass amount of bandwidth and is choking the network. IT continues to fight the good fight on a daily basis to maintain network SLAs when these bandwidth hogs are deployed across the existing network.
  • Latency sensitive applications are suffering: When networks are oversubscribed, latency sensitive applications such as access to VDI desktops, real-time web conferencing and voice/video communications are impacted and results is poor user experience and dissatisfied customers.

Bringing Your Campus Network into the Modern Era

For many years, campus networks have seen little innovation beyond incremental link speed enhancements. Years of piecemeal upgrades have turned traditional legacy campus networks, which should provide a unified network architecture, into a complex and fragmented patchwork of network devices.


Campus networking has reached a point where traditional network architectures are struggling to keep up with users’ relentless demands for both seamless mobility across the campus and pervasive access to latest-generation applications. It is increasingly challenging for IT departments to maintain network Service Level Agreements (SLAs) and to enforce specific access policies across a broad range of wired and wireless users and devices.




Two years ago, we formed an alliance with Aruba. It introduced our best-in-class integrated wired and wireless solution optimized for the LAN environment. The solution was designed to simplify implementation and management, providing a consistent experience no matter whether connected via wire or wirelessly.  It created a central control point for our customers to manage user and device access as well as monitor and manage their network infrastructure end-to-end, lowering the cost of troubleshooting and reducing time spent on network management.


Our champion customers like Levi’s Stadium, Kilgore College, and Isle of Wight College use our switches as the network infrastructure for powering and scaling their wireless networks to provide fast, reliable and secure connectivity. Our cooperative technical support with Aruba makes both teams easily accessible with a single phone call so that users can ask questions or raise issues and get answers in a timely manner.

In his VMworld 2015 keynote address, Pat Gelsinger stated that to dominate in the mobile-cloud era, organizations must be “Ready for Any.” Innovating faster, fully engaging customers, and empowering employees—all while protecting their data from attacks. He stated that there are 3 billion mobile clouds connections today and the rules of the game will change to meet a projected 7+ billion within 5 years.


Afterwards I strolled the aisles at VMworld and talked with vendors to understand their vision for the future. How will things change? How is your solution helping me change?


Five Signs it’s Time to Upgrade Your Network

by Jeff Sejourne ‎08-13-2015 12:05 PM - edited ‎09-03-2015 10:16 AM (2,329 Views)

How old is the equipment running your campus network? Older than 5 year? Do you experience recurrent network outages? Do you struggle with poor quality voice and video communications? Do you pay too much to maintain your legacy equipment? Do you have trouble scaling up the network to accommodate new business needs? If you said “yes” to any of these questions, it may be time to upgrade your campus network. We’ve put together a list of the five telltale signs it’s time to upgrade your campus network.



It's really fascinating to see how customers are innovating and migrating their core business from a physical to virutal world.


8 Ways Brocade is Building the Network of Tomorrow, Today

by Rick Freedman ‎04-07-2015 05:01 AM - edited ‎04-07-2015 08:00 AM (8,003 Views)

This morning Brocade announced new product and technology enhancements for its HyperEdge Architecture Campus Networks. The really exciting parts of the announcement were the new software technologies – Switch Port Extender and OpenFlow 1.3 support, which will simplify network management and enable software defined network innovations.


The hardware addition is the Brocade ICX 7250 Switch – a new entry-level switch that allows organizations and businesses to easily scale 10G uplink capacity and port density for increasing campus video and wireless demands. Combine these new hardware and software additions foreshadow how customers will be able to adapt and scale their network of today into the future.


A recent Gartner survey shows that 75% of data center professionals are expected to adopt Software Defined Networks (SDN) within the next five years, though only 7% already have SDN in use today. That’s consistent with the customers I talk to who have an eye to the future, but aren’t ready for these new technologies… yet. They know it’s coming and want to be prepared for the New IP. Their priority is building a network infrastructure that meets their needs today that can meet rapidly growing demands for wireless access, video, VDI and other network services that are taxing their legacy networks.


Most customers are looking, and hoping, that their infrastructure investments will last 5-7 years. And, in many cases 7-10 years. As they examine their options, they’re also very cognizant of the fact that these demands will continue to increase. So, while customers examine their options they have consider what they will need in the future, as well as how they will be able to take advantage of new technologies as they become available.


Last year, 2014, was our first presence at Aruba Atmosphere – for myself and for Brocade – and we were graciously welcomed by the Airheads community. As new Aruba partners we had a great opportunity to showcase unified wired/wireless solutions., featuring demonstrations of our integration points with AirWave and ClearPass. Additionally, as a leader in Software-Defined Networking (SDN), our breakout sessions drew a lot of attention and we received a lot of interesting feedback from the community about their views on SDN in the campus.


Over the past year, the partnership has grown stronger with delivery of the promised joint software integration and many joint customer deployments and success stories. We’ve worked jointly to make the customer experience seamless across the wired and wireless networks for both end-users and network administrators – with joint software development and unified technical support services. Customers like Levi's (SF 49ers) Stadium, Kilgore College and Westmark School attest to the importance and value of this partnership.


Integrated best-of-breed technology, management and support.  And now best-of-breed financing?  Really? No capital outlay with flexible operating expense options.  Nice to know when technology and financing move so fast in the network world. Only available from Brocade and Aruba.


As if the original deal wasn’t already sweet enough, two best of breed partners have now added unique industry acquisition methods. Just this month, Brocade and Aruba announced that the partnership has been extended into integrated financing. 

Now customers purchasing wired and wireless networks can include the equipment for both into a BNS subscription - expanding opportunities and virtually eliminating risk. Can your vendor(s) of wired and wireless networks offer a more tightly integrated solution with regard to technology, management, support and financing options?


SC14 New Orleans: Customers find Simplified Campus Networking on the Path to SDN

by Prasida Menon ‎11-25-2014 11:22 AM - edited ‎11-26-2014 10:45 AM (3,915 Views)

As the curtain fell at SC14 in New Orleans last week, passersby at Brocade’s booth 2145 heard a huge applause - the 3D Printer Raffle had found its winner. While the rest of us were wrapping up our final day at the SC14, I could not help but ponder on the many fruitful customer discussions and exchange of ideas that made this event such a massive success for attendees and participating vendors.


This year we showcased a wide array of Brocade solutions, while also actively contributing to the SCinet community with Brocade’s routers and switches. All of Brocade’s latest platforms along with our new Brocade Vyatta controller were exhibited to the scientific community demonstrating solutions such as, High-Performance Computing, Software-Defined Networking, Data Privacy and On-Demand Acquisition. 


Keeping up with User Demand Requires Out-of-the-Box Thinking

by Jeff Sejourne ‎11-04-2014 02:52 AM - edited ‎11-04-2014 04:14 AM (2,787 Views)


Ubiquitous video calls, unified communications, Virtual Desktop Infrastructure (VDI), wireless access at wired speed greatly contribute to user productivity, but these new applications and devices, place immense pressure on the network, a network that was not originally designed to handle such demand.


Traditional legacy campus networks have been through years of incremental technology improvements and patchworks that have turned what should be a coherent network into a complex and fragmented collection of loosely coupled devices.

Right across the street from Brocade at the newly opened $1.18 billion Levi’s Stadium, home of the 49ers football franchise.  Every fan will strike gold when they fire up their smart phone or tablet on the stadium’s Wi-Fi network. With dual high-speed 40Gig pipes, a massive Brocade switching system, and Aruba 1.3Gbps 802.11ac Wi-Fi everywhere, the stadium is a tour de force of Silicon Valley networking and fan engagement technology.


Does SDN Have a Role in Campus Networks?

by Jim Metzler on ‎09-29-2014 04:31 PM - last edited on ‎09-30-2014 10:36 AM by (4,215 Views)

The vast majority of the discussion about SDN to date has focused on the data center. Since the network is a lot bigger than just its data center LAN that begs the question “Does SDN have a role in campus networks?”


Unlocking Flexible Security in an Enterprise World

by Prasida Menon on ‎09-26-2014 12:02 PM (3,218 Views)

One of the biggest challenges faced by the enterprise world today is how to overcome the security issues faced in many of the enterprise organizations. The early adopters of the BYOD strategies have learnt their lessons the hard way – a plethora of mobile devices in the enterprise result in huge demand for authentication and authorization framework caused by the sheer volume of devices and each device’s varied authentication interface.


Did you know that the root cause for many upgrades is not based upon new applications or user demands, but based upon Planned Product Obsolescence and Vendor-Centric Business Practices?


Consider the dramatic increase in incumbent network devices moving to end-of-support (EOS), from 38% to 45%, in Cisco’s product portfolio.  This was reported by Dimension Data, one of Cisco’s top notch partners no less.


Sidestepping Security Woes of BYOD

by Prasida Menon on ‎09-04-2014 09:06 PM (3,248 Views)

My previous blog detailed how organizations worldwide can adopt BYOD programs seamlessly using innovative stackable switch solutions. While a solid network infrastructure and enhanced capacity form the backbone of any BYOD program, security is one of the overarching issues faced by many organizations today. With over 23% of US based employees experiencing some form of security compromise on their personal devices in any single year, it’s not surprising that a recent Gartner study shows over 75% of organizations cite security issues as their biggest concern for adopting BYOD programs. What is Brocade's Campus solution to help mitigate BYOD security risks faced by organizations worldwide?


Well, many of you may be wondering what happened after the network disruption that Cisco did a decade ago. Where are we going from there? Do you still want to stay status quo?


Not all Stacking is Created Equal

by Prasida Menon ‎08-22-2014 04:17 PM - edited ‎09-04-2014 02:40 PM (5,122 Views)

With BYOD strategies maturing, organizations worldwide are frantically looking to adopt BYOD programs, not only to improve employee satisfaction but also to improve user productivity. According to a recent Gartner research half of the enterprise world says they intend to move to BYOD for smartphones alone by 2017, let alone other devices such as tablets, standard mobile phones and PCs. What are the steps taken by Brocade's Enterprise LAN switches to mitigate these issues?

Wired networks are dead. Long live wired networks.

by Rick Freedman on ‎07-03-2014 06:10 AM - last edited on ‎10-23-2014 01:25 PM by (3,573 Views)

The expansion of wireless networks in recent years has been phenomenal.  The rapidly growing use of smartphones, tablets and corporate acceptance of BYOD has forced businesses to offer wireless connectivity virtually everywhere.  Pundits have forecasted the decline of the wired network as we know it and, perhaps, the demise of wired-only network companies. 


How then, can a network company that only makes wired network switches still be growing?  As with most technology companies, it requires a business to adapt and change, to survive and thrive.  The end-user connectivity may be changing, but the importance and dependence on the wired network has never been greater.


SDN Hybrid Mode: Connecting the Dots

by Simon Pollard on ‎06-10-2014 05:00 PM - last edited on ‎10-23-2014 03:14 PM by (3,004 Views)

Combining all the elements of a modern IT infrastructure can often feel like solving a technological dot-to-dot puzzle; there aren’t any visible relationships between all the points that must be interconnected but when they are joined up they form a coherent picture. Every IT professional is painfully aware that the reality is somewhat different; the relationship between the different components – network nodes, servers, storage and applications – runs deeper than mere connections;


Elastic Networks

by Simon Pollard on ‎06-10-2014 12:27 AM - last edited on ‎10-23-2014 03:15 PM by (2,841 Views)

One of the biggest challenges when designing any new system that requires an element of capacity planning – computing, networks, transportation, to name a few - is deciding what the primary criteria are; should you go for a big initial costly build-out and hope that all of the capacity is used? Or aim for something more flexible that can start smaller and be expanded as required to deliver greater capacity. Factors such as the need for up-front investment and sketchy predictions of future demand need to be considered and the result can sometimes be a difficult compromise.


SDN Killer Apps for the Campus

by Jeff Sejourne on ‎05-16-2014 06:22 PM - last edited on ‎10-23-2014 03:27 PM by (3,795 Views)

The data center is getting all the SDN attention these days, but the applications that will help SDN cross the chasm may actually very well come from the campus.


SDN has the ability to radically transform campus networks over the next few years and address today’s most acute management challenges.  Campus networks require application specific policies like security & access control, VLAN traffic isolation and QoS policies to be provisioned across the network one switch at a time. This consumes a lot of resources and results in a static network that cannot be easily updated as business requirements evolve and new applications are deployed.


Brocade Products and Website NOT Affected by Heartbleed Vulnerability

by Jeff Sejourne on ‎04-16-2014 12:52 PM - last edited on ‎10-23-2014 03:30 PM by (8,731 Views)

Since early last Wednesday, the web and media have been abuzz over a new security vulnerability they have named the Heartbleed bug. Heartbleed is a security vulnerability inOpenSSL, an open-source protocol primarily used to encrypt web communications but also used by IT personnel for connecting securely to network devices and servers for administrative purposes. After thorough investigation, our engineering teams have concluded that neither our products nor website are affected by the Heartbleed bug.
