Performance and Security for Azure Cloud Applications

by Nick Vale on ‎05-20-2015 05:00 AM (1,560 Views)

Moving your Apps to the cloud will mean you need to address the issues of availability, performance and security issues when you architect your cloud infrastructure. Also don’t under-estimate the potential complexity of your infrastructure if you start to mix cloud friendly technology with your Data Center based hardware products – just how many GUIs do you need to learn?! Try and select products that can be deployed wherever you need them – cloud as well as a physical or virtual data center.


The headlines on cloud outages seem to have become less frequent but there is still a risk of your Apps becoming unavailable to users unless you look at cross region deployment or multiple clouds.


Today Brocade released v1.3 of our SDN controller. This release incorporates the OpenDaylight SR3 package, which primarily provides bug fixes. The Brocade v1.3 release also provides support for all Brocade-developed SDN applications, such as Path Explorer 1.2 and vRouter EMS applications.


You can try the latest release for free, with 60 days of free support, by downloading it here. Documentation such as user guides can be downloaded at the same time. Additional information to help you get started can be found in the Brocade DevNet Community and on GitHub.


Downloads of the Brocade Vyatta Controller have been gratifying and interesting. The largest group of downloaders so far is the VAR and SI community, with certain regions especially interested in our developer edition. There is also a very healthy mix of Enterprise users representing a wide range of verticals and use cases. Telcos and cloud service providers are typically the most advanced in their deployment timelines, and you can expect to hear more in the next few months about how they are using the Brocade controller as part of their SDN strategy.



Brocade Vyatta Controller – 1.2 now available

by lcaywood on ‎03-19-2015 08:51 AM (2,727 Views)

The Brocade Vyatta Controller is a continuous-build distribution of the OpenDaylight controller. With the Brocade controller, we’ll be issuing dot releases approximately every 6 weeks to provide our users new features and bug fixes as they are accepted by the OpenDaylight Project. Whenever you download the Brocade Vyatta Controller, you’ll be getting the latest Brocade package; previous releases are maintained on MyBrocade. Our 1.2 release primarily includes the Helium SR2 package. This is mostly bug fixes.


While I’m at it, I wanted to clarify my answer to a question asked at Networking Field Day 9: Ivan Pepelnjak asked about the composition of the Brocade controller, as he’d noted that not all sub-projects are mentioned in the Brocade documentation. This is because, although we work with the entirety of the OpenDaylight Project as I indicated during the session, there are several sub-projects that are very new and are not fully fleshed out and operational as yet. Therefore those projects are not officially supported within our distribution. We work within the Project to help mature these features, and as they become operationally viable and can be supported in a quality-assured package, they will be officially incorporated.

New IP: Just in Time, Just in Place Network Services

"It was software; in cyberspace. There was no system core; it could not be shutdown.”

- John Connor (Terminator 3: Rise of the Machines)


When it comes to advanced networking, we want what we want, how we want it, when we want it: But as humans, we change our minds…a lot. And we can do this because we are wetware, we can grow, change, adapt, even heal.


Ok, so we want products that can morph as our needs do.


The Self Defending Network

by AceKrish on ‎03-02-2015 10:40 AM (14,885 Views)

For years, security has been about prevention, detection and remediation. And yes the emphasis has shifted in recent years towards detection and remediation but prevention is still a key component of any security strategy.


While the prevention methods have evolved over the decades – many network security devices still require human intervention to help ward off the attack. This becomes even more complex when applied to the virtual world where servers are spun up and down based on the needs of the business. How do you reduce the time for action with human intervention and allow for a self-defending network while ensuring network security?


Service providers continue to be challenged with the explosive network traffic growth based on mobility, cloud and video services as evidenced with their demands for large 100Gbps transport links and beyond. At the same time, service providers need to continue deploying new technologies and services to stay competitive and address the needs of their customers. In building their next-gen networks service providers aim to be efficient and cost effective while leveraging new technologies such as network virtualization, big data analytics and IP Voice (VoLTE & VoWIFI), which in turn come with their own challenges. And this all needs to be completed while addressing concerns around things like security, increased network visibility and more granular service flow management. These must be addressed as part of enabling new services successfully.


Living Life On the Virtual Edge

What imagery does “over the top” conjure up? For some folks it is the ’87 Sly Stallone flick. For others, it's a renegade that takes things to the extreme. But ask the question to a Telecom Service Provider and don’t be surprised if they have daggers in their eyes! Why so? Let’s look at what Wikipedia has to say about it – “In broadcasting, over-the-top content refers to delivery of audio, video, and other media over the Internet without the involvement of a multiple-system operator in the control or distribution of the content.

What Makes an Open SDN Controller: Tech + Community

by lcaywood ‎01-20-2015 12:10 AM - edited ‎01-21-2015 03:29 PM (3,413 Views)

Back in September, we announced the Brocade Vyatta Controller, a commercial package of the OpenDaylight controller. We did an initial release in November and since that time have been working with our early adopters to understand and respond to the full range of their needs.


The single biggest challenge for any organization looking at SDN is simply getting started, non-disruptively. That means not having to spring for a lot of new equipment, but it also means supporting the organization through a ramp-up in skillsets and a shift in processes. So we’ve spent a fair amount of time developing ancillary education and support services in addition to making it easy to acquire the controller in the first place.




Dans notre secteur, il y a deux écoles : ceux qui pensent que le futur des réseaux réside dans l’ouverture, et ceux qui pensent qu’une approche propriétaire est indispensable.


I’ve spent the last few months working closely with the OpenDaylight and OpenStack developer teams here at Brocade and I’ve gained a heightened appreciation for how hard it is to turn a giant pile of source code from an open source project into something that customers can deploy and rely on.


What do a SDN Controller and Superman have in common?

The SDN controller of today can be likened to Clark Kent who plods along doing one thing well – print journalism. The SDN controller that we need is more like Superman – seeing, hearing and protecting everyone and everything. And once we see the SDN controller donning the garb of Superman we will never go back to Clark Kent will we? Read on….

Open vs Proprietary? A question of practical philosophy

by Curt.Beckmann ‎08-07-2014 07:16 AM - edited ‎08-07-2014 08:34 AM (3,543 Views)

The early debate about "open" seems to have been resolved.  Or did it just go underground?


What's the buzz about SDN & NFV?

by Joanna Lee ‎07-16-2014 03:14 PM - edited ‎07-24-2014 09:59 AM (3,672 Views)

Introducing the Brocade Terminology Guide: a guide that will aim to help people better understand, organize, and absorb a portion of the many terms around campus by use of strong visuals. Every week, new posts will be available on Brocade Communities and will be focused around a certain theme. Be sure to also join the conversation on social media via #BRCDology. 


Since this week marks the launch of the Guide, it will be all about going Back to Basics. The terms “SDN” and “NFV” vibrate at a constant stream around here and throughout the networking industry, as if someone whispers it through the walls. So, what really is the buzz about SDN and NFV? Read more to find out!


The OpenStack Summit that took place in Atlanta two weeks ago is the first I’ve attended myself, so I gave myself some time to absorb my own experience and to read the subsequent press coverage before adding to the noise.


As I boarded my plane home, I tweeted: “Top 3 Q's I got asked at #openstack: 1) Roles of ODL vs Neutron? 2) How to make money in open source? 3) When will OpenStack be usable?” I’ll address #1 and #3 below…#2, of course, remains the multibillion-cowry shell question.


What should be the respective roles of ODL and OpenStack Neutron?


At the 10,000 foot level, it can sound like OpenStack Neutron and SDN controllers do more or less the same thing—provision and manage networks for cloud consumption. This has led to some discussion as to what should be done by which entity. Before jumping into the theorizing, though, it’s good to have an understanding of the current state of Neutron, the networking module for OpenStack. Rivka Little of SearchSDN provides a good summary, starting in paragraph 3 of this article. Most critically:


“Inside the cloud, Neutron works with virtual switches and hypervisors to configure ports and devices, and provision virtual overlays and tenants. But a Layer 3 agent is responsible for connecting these tenants out into the data center and the Internet. All traffic in a single cloud environment runs through that same L3 agent, which creates a choke point. That Layer 3 agent also lacks dynamic routing.”


That’s not to say, however, that OpenDaylight or other controllers are replacements for Neutron. Neutron is simply the newest portion of OpenStack and evolving rapidly. Meanwhile, a number of the developers working on Neutron are also working on OpenDaylight, especially on integration between the two projects. Rivka Little’s companion article, Do OpenDaylight and OpenStack Compete or Complement?, provides a good picture of the real focus of the discussion ,eg the appropriate degree of abstraction for Neutron.


Using OpenDaylight with OpenStack (slides and video with demo) gives a generic overview of how the two work together. For a more concrete picture, this demo shows how to instantiate and orchestrate some Vyatta vRouters with OpenStack and OpenDaylight.



Supporting Multi-Tenancy Between Data Centers


The SearchSDN quote above highlights a key use case for OpenStack: maintaining tenant connectivity and policy in clouds constructed from multiple physical data centers. Brocade has been working with Huawei on a proposal to do just that, which was shared at the Design Summit portion of the Atlanta event. You can read the blueprint here.


One of the blueprint authors, Mohammed Hanif, talks about it in this video:



This brings us to the “usability” questions: not When, But By Whom, For What?


First, some data points: I’m told there were virtually no actual user organizations at the summit a year ago. I don’t know the actual attendance breakdown in Atlanta, but anecdotally, roughly ¼ of the badges I had time to eyeball there were user orgs. Although the headliners (Walt Disney, Wells Fargo) are very large companies, most were not—something borne out in OpenStack’s own User Survey, which shows that 60% of deployments are in companies of under 500 employees. At the opposite end of the spectrum, most of the large, non-vendor organizations present were not large enterprises, but telcos. Which brings me to the point of this section.


Last fall, Geoff Arnold wrote a much-discussed post called Whither OpenStack, in which he debated whether it made much sense for enterprises to try to use OpenStack for private clouds. He also made reference to telcos having some specific needs of their own.


Consensus now seems to be emerging that there’s room for enterprises to develop and grow private clouds on OpenStack over time, especially with the certifications and hardened distributions that are now more firmly in place.


At the same time, NFV has seen remarkably rapid adoption in the telco space, and there’s clearly an appetite for using OpenStack to orchestrate those functions. Some additional work (slides) needs to be done within OpenStack to really support that, but we may well see a telco-centric body of work emerging over the next few months, with NFV at the core.


Late-breaking: a scrap over Fibre Channel in OpenStack


In a post last week, Stephen Foskett questioned whether there’s even a need to include Fibre Channel initiatives within OpenStack. J Metz responded this morning that it’s a moot question, since Fibre Channel is already implemented in OpenStack, with more proposals for Juno release. Instead, Metz says, “the question is related to the level and extent of which Fibre Channel can be managed and controlled by some type of orchestration layer using OpenStack infrastructure.” It’s a good question, and one that will be answered as users road-test it and OpenStack capabilities evolve.


In the meantime, if you’re curious where Fibre Channel is today in OpenStack, here’s a brief talk given by Andre Beausoleil on the FC Zone Management capabilities implemented in Icehouse.

UPDATE: Efficient and Scalable DDoS Mitigation with SDN (SDN Idol Award WINNER!)

by mschiff ‎03-03-2014 08:57 AM - edited ‎03-06-2014 05:04 PM (4,795 Views)

DDoS attacks are on the rise. That statement by itself might not be that interesting because in this climate of "cyber insecurity", it probably wouldn’t surprise anyone that the number of attacks is increasing.  However, what is more interesting, and even more troubling for networks, is that the size of these attacks is on the rise, with some attacks reported at over 400 Gbps. And yet the same solutions that were used for much smaller attacks are being used in attempt to detect and mitigate these security threats.

The Year of NFV

by Kelly.Herrell on ‎02-23-2014 11:01 PM (2,724 Views)

In the span of just over one year “Network Functions Virtualization” (NFV) went from a non-existent term to a dominant theme at Mobile World Congress. For a trend to skyrocket from absolute obscurity to being showcased at the world’s largest networking show is a very rare phenomenon.


The importance of Intel to the NFV movement cannot be overstated. At the root of agility and economics is an open ecosystem system of software with a common, powerful, highly economical hardware platform to leverage. The hardware must be able to be delivered in a variety of form factors given the wide variety of network infrastructure that exists, but it’s crucial that there be an architectural similarity in order for the software ecosystem to thrive.


Changing Perceptions of the NFV Opportunity

Next week, arguably one of the biggest SDN events will be held in Denver, Colorado.  At this event there will be more live demonstrations of SDN applications and solutions by organizations actually using SDN than there have been at any other event to date.  A vibrant community will come together for nearly a week to openly share technology and ideas with one another for the betterment of each organization scratch that, mankind.  If you have an interest as to where the world of networking is going, then you should pay attention to what is happening at Supercomputing 2013 (SC13). For the last 25 years, the Supercomputing Conference has been the premier event for the High-Performance Computing community, attracting members of research and education networks, universities, national laboratories, and other public and private research institutions. It is at this event, and really this event only, that you can get a preview of what networking may look like in 2, 3, maybe even 10 years down the road.

These are exciting days in my Forwarding Abstractions Working Group (FAWG); the past 15 months of work is just now producing results that will be instrumental in enabling our SDN future.  Past is meeting future in my extended present, and each week brings us closer to fruition.  Some weeks ago, FAWG produced a “preliminary final” document about our framework enhancements for the OpenFlow ecosystem. 


Multi-Layer Network Provisioning and Optimization with SDN

by mschiff on ‎10-14-2013 09:32 PM - last edited on ‎10-28-2013 09:20 PM by bcm1 (3,104 Views)

The true value of SDN will come from the real-world applications that it will enable. Although at times, when listening to vendors describe their SDN strategies, it seems like we are hearing more about solutions in search of a problem, and not the other way around.  Today I am happy to be part of an announcement that is not that.


For service providers, the onslaught of data on their networks has made them re-examine and re-examine again how to build a more efficient network. The goal is to have a dynamic network infrastructure at all layers to not just handle the massive amount of traffic, but to also unlock new revenue streams by providing premium services with greater SLA’s to customers.


Today, Brocade is excited to be part of an announcement of a successful demonstration of such an SDN application. In collaboration with Infinera and ESnet, this demonstration shows how SDN can be used to provision services and automatically optimize network resources across a multi-layer network as traffic and service demands change.  By leveraging an application developed by ESnet, called OSCARS, we were able to show two use cases:


  1. The first phase of this demonstration showcases how the OSCARS application, integrated with a Floodlight controller, uses OpenFlow for orchestrated, multi-layer, automated provisioning across a packet optical 100 GbE network comprising of Brocade MLXe Core Routers, Infinera’s DTN-X converged OTN/WDM optical platform and additional OpenFlow enabled Layer 2 switches.
  2. The second phase of the demonstration focuses on multi-layer network optimization and demonstrates how proactive detection of increasing bandwidth of packet flows can trigger the OSCARS application to dynamically re-optimize the underlying packet-optical topology and re-route the large flow to bypass an intermediate packet switch, improving overall network resource utilization and increasing operational efficiencies.


Originally a research project by ESnet, OSCARS has helped scientists collaborate with one another from around the world by moving massive amounts (in petabytes) of mission-critical data generated from research and experiments.  Now with the demonstration announced today, this provisioning can be done at both the routing and transport layer using SDN.  You can see the details of the demo setup in the diagram below.




This demonstration also exemplifies the power of an open SDN ecosystem. One of the major tenants of SDN is to unlock new levels of innovation for network operators. By establishing APIs between layers, software components and best-of-breed network elements this can ignite innovation, enabling the development of customized applications.


This week the demo will be on display at SDN & OpenFlow World Congress in Bad Homburg, Germany. If you are there, please stop by the Infinera booth #39 to see it live.  Also check out the Brocade booth #41 where you can learn more about this solution in addition to other Brocade SDN and OpenFlow solutions.  If you aren’t lucky enough to be in Germany, we will be showcasing the demo during a DemoFriday hosted by SDNCentral at 9am on November 22, 2013. Stay tuned for more details on this live virtual event where you will have a chance to hear commentary from Brocade, Infinera, and ESnet, see a live demonstration, and have time for questions and answers.

A million OpenFlow router ports and counting!

by anandar on ‎09-26-2013 06:58 PM (969 Views)

Yesterday, Brocade announced at the annual Analyst and Technology Day that we have shipped more than a million OpenFlow-enabled router ports to date. So, what does that mean in the evolving world of SDN?


Have you ever had a situation when you came across a feature on a gadget/appliance you already own, that suddenly improves your productivity? Discovering OpenFlow on an MLX port is kind of similar! And the capital cost you incur to evaluate OpenFlow for a specific use case on an MLX infrastructure? Zero! Because every MLX port shipped to date can be upgraded with software to support OpenFlow.


As the market moves from the initial enthusiasm of OpenFlow to more practical deployments, it is logical to ask a few pertinent questions:

  • How does one migrate from an existing infrastructure that is not OpenFlow-aware to one that is. This is where a capability such as hybrid port mode is so relevant. Other posts on this community have highlighted how this is a practical path to SDN because it enables SDN capabilities without forcing a forklift.
  • How does one perform flow processing at scale? Is there a performance penalty? Doing these at scale implies having the right system architecture in place to process such flows without any performance penalty.
  • What does future-proofing really mean? The benefits of an architecture are best revealed well after it is designed and deployed. In the case of MLX, the foundation of a fully programmable architecture has meant that a technology that did not even exist when the platform was designed, could still be fully supported without any penalties.
  • What SDN controller should I choose? Today, there are more choices than what were available two years ago. Apart from the commercial controllers in the market, Open Daylight with the Hydrogen release is just around the corner.


If you have MLX deployed in your network infrastructure today, try out OpenFlow. There is no cost to creating a slice of your infrastructure for OpenFlow and having it concurrently coexist with your existing network protocols/present mode of operation. You may discover a more programmatic way to solve problems such as service chaining, traffic steering or others.
