Why don't all companies take a customer-centric approach to service?
Being part of the Packet Design Customer Care department and specifically the Technical Support group, I constantly ask: What more can we do to better serve our customers? My own recent experiences as a customer of various consumer products revealed some things that I can correlate to my job and Packet Design’s customer centric approach.
A Tale of Two ISPs
I use two different Internet service providers and experienced issues with both recently. The first, which I will call “ISP1,” is a wired service provider. One day my service was disconnected, as my subscription had expired. I called them to ask for a renewal at 10:00 a.m., and the customer care executive confirmed a collection agent would arrive shortly. (They have a door-to-door bill collection staff, and they turn your service on immediately upon payment). The agent did show up to renew my service.
At 4:00 p.m. (six hours after I had already renewed the service), I received a call from the same ISP1 asking if I would like to renew, since my Continue reading
Summary
• Application Roll Out Reduced from Weeks to Minutes
• VMware NSX Enables Better Agility, Flexibility and Security
Recently I had the opportunity to speak with the team at Schuberg Philis about their successful, production deployment of VMware NSX. As background, Schuberg Philis is an innovative business technology company and an important player in the field of mission critical outsourcing services. The company serves customers across financial services, retail suppliers and utilities, and therefore must comply with the highest international risk management and corporate governance standards, while remaining flexible to evolving customer needs.
The adoption of VMware NSX based network virtualization has transformed the way Schuberg Philis runs its IT. In order to provide 100 percent functional up time of its customers’ critical applications, Schuberg Philis continuously optimizes its infrastructure and processes. However, the company increasingly saw its network as a barrier to increasing business agility.
To solve this challenge and to accelerate application roll out, the Schuberg Philis implemented a software-defined data center environment, and deployed VMware NSX. Schuberg Philis is taking advantage of the VMware NSX platform’s flexibility, security and agility to accelerate the deployment of applications to customers. Schuberg Philis customers now have easy access to Continue reading
After discussing the basics of MPLS and LDP in our Tech Talks chat, Seamus Gilchrist and myself focused on a concept that perplexes many networking engineers entering the MPLS world: the relationship between Forward Equivalence Classes (FEC), LDP and BGP.
While this is likely widely known, I figured this was worth documenting for someone that might not have done this before. If you’ve looked at CoreOS at all you know that in order to connect to a CoreOS server it needs to be configured with your machines SSH key. This is done through the cloud-config file which we’ll cover in much greater detail in a later post. So let’s quickly walk through how to generate these keys on the three different operating systems I’m using for testing…
CentOS
You’ll need to have OpenSSH installed on the CentOS host you’re using in order for this to work. Check to see if it’s installed…
Now let’s check to make sure that we don’t already have a key generated…
There’s no .ssh folder listed in our home directory so let’s move on to generating the key.
Note: If there was a .ssh folder already present, there’s a good chance you already have a key generated. If you want to use this existing key, skip ahead to after we generate the new key.
Since there isn’t a .ssh folder present, let’s create a new key. Continue reading
Outsourcing is complex, and there are lots of ways it can go wrong, or simply fail to deliver. I’ve put together a list of things that I see going wrong with outsourcing arrangements. Of course it’s not exclusive!
There’s a few different types of outsourcing. It might mean procuring a commodity service – e.g. IaaS, or it might mean handing over your existing environment and staff to a third party. There’s also a whole range of levels in between, but the usual deal is: Some part of your environment gets managed or delivered by someone else, according to the terms of a fixed agreement.
Here’s a few things I’ve learnt to watch out for (nb not all these items apply to all types of agreements):
If your outsourcer is managing your software, the contract usually covers applying security patches and bug fixes. But what gets missed is larger upgrades – e.g. ESXi 4.1 to 5.x. Everything goes OK for a while…and then your version goes End of Support.
It then becomes a major drama to get the upgrades sorted out. For financial purposes, you may not be able to do major Continue reading
Facebook engineering has recently introduced their next-generation data center network architecture planned to be operational in the new Altoona facility. Introducing data center fabric, the next-generation Facebook data center network
In this post we are going to look at the design proposed and break down some of the reasons why this design was necessary although maybe still not ideal.
Within Facebook’s data center the network is a critical component driving this social networks ever increasing appetite to connect people together. The challenges unfold on two axis, the first being the explosive growth in the user population and its increasing demand and access bolstered by modern mobile devices and the second related to the exponential growth of machine to machine traffic required to aggregate and compose information which we all know and love. Due to the nature of Facebook applications, machine to machine communications is “several orders of magnitude larger than what goes out the Internet”
The need to parallelize work becomes a daunting task in this environment requiring an enormous communication fabric for internal processing.
the rate of our machine-to-machine traffic growth remains exponential, and the volume has been doubling at an interval of less Continue reading
A long time student of INE, Neil Moore has done it again, last time becoming the worlds first 7x CCIE, and this time becoming the worlds first and only 8x CCIE. And no, he doesn’t work for Cisco.
As a side note, INE has been experiencing phenomenal growth, and tremendous passing rates for people that have been sitting our R&S, Data Center and Collaboration bootcamps. In fact, of just the bootcamps we’ve held this year, nearly all of our students have reported back to us a pass in the 3-4 weeks following their bootcamp experience. Now mind you, these folks come to us studied up and prepared for the bootcamp, but they all credit us as being the deciding factor in their pass.
We’re also adding new content all the time, including Python scripting, Openstack and SDN such as OVS. Check out our Black Friday deals and grab an All Access Pass or sign up for a bootcamp and check out what’s new!
Pica8 Says ‘Yes’ and Challenges the FUD
Up to this point, OpenFlow has mostly been deployed in research and higher-education environments. These early trials have shed some light on interesting use cases, what OpenFlow is good for, and of course, what OpenFlow might not be so good for.
This is important because OpenFlow and SDN adoption is only going to grow. It’s imperative that we understand these limitations – specifically, what’s real and what’s FUD.
One of these is scale.
If you’ve kicked the tires on OpenFlow, one question you may have heard is “How many flows does that switch support?” However, this question is only part of the story. It’s like asking only about a car’s top speed when what you should be thinking other things too – such as fuel efficiency and maintenance. So to figure out the right questions, we first need to go over a bit of background.
In its most basic terms, any network traffic, whether it’s Layer 2, Layer 3, or something else, is governed by a of forwarding rules as defined by a series of protocols. If it’s this MAC, do this. If it’s that IP, go Continue reading

You know those times when you paste innocuous config to a router and it just freezes up on you? Even if you know you’ve done nothing wrong it can be a few scary seconds until the router starts to respond again. While reading up on onePK I was trying to come up with a use case. Though I eventually thought about some other things that would actually be useful. The very first thing that came to mind was something to test just for fun.
Picture this; You ask a co-worker to login to a router and shutdown an interface which won’t be used anymore. Your colleague logs into the device and disables the interface and the session hangs. Only it doesn’t just hang, it’s dead and apparently your colleague can’t ping the device now. At this point it can be a good idea to ask your co-worker about what exactly he changed.

Last week we hosted the Open vSwitch 2014 Fall Conference, which was another great opportunity to demonstrate our continued investment in leading open source technologies. To get a sense of the energy and enthusiasm at the event, take a quick view of this video we captured with attendees.
I’ve been thinking about the key takeaways from everything I saw and everyone I spoke with.
First, there’s huge interest in Open vSwitch performance, both in terms of measurement and improvement. The talks from Rackspace and Noiro Networks/Cisco led me to believe that we’ve reached the point where Open vSwitch performance is good enough on hypervisors for most applications, and often faster than competing software solutions such as the Linux bridge.
Talks from Intel and one from Luigi Rizzo at the University of Pisa demonstrated that by bypassing the kernel entirely through DPDK or netmap, respectively, we haven’t reached the limits of software forwarding performance. Based on a conversation I had with Chris Wright from Red Hat, this work is helping the Linux kernel community look into reducing the overhead of the kernel, so that we can see improved performance without losing the functionality provided by the kernel.

Relying on a DMZ to protect your network and data is like putting money in a bank that depends on one guard and a single gate to secure its deposits. Imagine how tempting all those piles of money would be to those who had access — and how keen everyone else would be to obtain access.
But banks do not keep cash out on tables in the lobby, they stash it in security boxes inside vaults, behind locked doors, inside a building patrolled by a guard and secured by a gate. Likewise, network segmentation offers similar security for an organization’s assets.

I recently received a note from a colleague from ZeroHedge (http://www.zerohedge.com/news/2014-11-21/not-so-fab-1-billion-valuation-15-million-year) that was officially calling the beginning of the bubble bursting based on the untimely (or timely depending on your perspective) demise of the startup Fab. I had never heard of Fab, but according to ZeroHedge, Fab “started out as a dating site for the gay community and then relaunched as a flash sale site for home decor – raised $150 million just over a year ago (at a $1 billion valuation), but as TechCrunch reports today, multiple sources have confirmed that Fab is in talks to sell to PCH International for $15 million in a half cash and half stock deal. Pets.com?”
Its a fair question indeed – are we seeing the same pattern we saw in the last bubble (i.e. Dot-Com 1.0) being repeated? Certainly, crazy valuations of equally crazy or non-existent business models are a cause for concern, but more important than that are the fundamentals of what is driving the speculation in the first place. In Dot-Com 1.0 we saw simultaneous speculative investment across at least 3 major areas: internet backbone infrastructure, internet edge/access Continue reading

News reports show cyber attacks continue to outpace IT’s ability to protect critical data, but teams that have built systems to deliver accurate threat intelligence can often end an attack before damage is done. Threat intelligence comes from commercially available information, ongoing analysis of user behavior and native intelligence from within the organization.
