In reviewing some opportunities for Plexxi this week, I was reminded that we have made things very hard on ourselves. Through no one’s fault but our own we have created monsters of networks that are impossible to maintain, debug, diagnose and understand.
I have been lucky in my career. Most of it has been in an R&D organization for a large network vendor, but always in positions where I was close to customers, close to customer networks, and of course with that comes the “close to customer networks that are not working well”. And while there are always exceptions, in most of these troublesome networks, the sheer complexity of the network contributed significantly to the problem at hand, even if the end result was a bug.
Finding and fixing issues in networks is often one of these activities where you spent almost half your time understanding the network and its intricacies, a quarter of the time debugging and diagnosing the actual problem, and a last quarter producing, testing and implementing the solution. And so often the problem is hidden in the understanding of the network. An additional link that was not documented. A spanning tree config that was slightly different on one switch. A LAG with slightly different LACP timers. One vendor’s version of MLAG behaving just slightly different than another. And the guy that configured it no longer works here.
Whether it is a support person hunting for a problem, or a sales engineer trying to propose a new design or product, the process always almost starts with pictures. Network diagrams are the most powerful thing we produce. They are also the most misleading piece of information we produce because without fail they are wrong. Or missing something that is really important for that one specific item you are chasing. Network engineers and architects love to draw, our world exists of boxes, circles and lines between them. The challenge is that a 2 dimensional representation of a network is always going to be abstracted and therefore will always miss something. A network diagram that articulates the overall architecture and design of a network is absolutely key and with a clean sheet of paper we always start out with something that is sensible, easy to understand and typically simple. And then weeks, months and even years of incremental needs and requirements start eating away at the clean design.
Over 20 years of networking have created an astounding amount of capabilities. What we have taught our switches and routers to do is really amazing, and our packet forwarding chip vendors have done an equally outstanding job keeping up pushing these capabilities into hardware. And lots of these capabilities slowly make it into your network, chipping away at what was the “perfect” architecture. In the end, we are configuring individual devices with endless amounts of functions. Functions that should be so simple you should not have to configure them by hand.
We all know that ethernet networks need to be loop free. It should be dreadfully simple to instruct your devices to “make it so”. Except that we have at least five ways to ensure it is loop free. And then only for a specific portion of the network. We all know VoIP traffic should get preferred treatment over regular internet or other traffic. But in the end we configure complicated access lists and mappings to DSCP values that then map into queues that then have to be hand crafted into a scheduling mechanism we believe does not mess up the original voice traffic we cared about, or the other important traffic. We know routers needs to exchange subnet information for reachability. But we end up with rather complicated protocols that have endless options, some apply globally, some to interfaces, some need filtering, some need adjusted timers, you name it.
Your equipment vendor will tell you that there will be bugs. A switch or router is no different than a regular application, there are millions of lines of code and bug free code does not exist. We as vendors need to help the network architect, manager and operator. We have to make it much easier to implement the functionality you require. You can help yourself by uncluttering your network as a regular activity. Think back to those pristine network diagrams you created before the network was installed. Instead of adjusting the diagram to represent reality, perhaps it is worth spending some time adjusting the network back to the diagram.
[Today's fun fact: there is an actual website where you can submit network diagrams to be rated by the viewing public. Really. http://www.ratemynetworkdiagram.com]
DevOps Summit 2015 New York, co-located with the 16th International Cloud Expo - to be held June 9-11, 2015, at the Javits Center in New York City, NY - announces that it is now accepting Keynote Proposals. The widespread success of cloud computing is driving the DevOps revolution in enterprise IT. Now as never before, development teams must communicate and collaborate in a dynamic, 24/7/365 environment. There is no time to wait for long development cycles that produce software that is obsolete at launch. DevOps may be disruptive, but it is essential.

The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs. In this Power Panel at 15th Cloud Expo (http://www.CloudComputingExpo.com), moderated by Ashar Baig, Research Director, Cloud, at Gigaom Research, Nate Gordon, Director of T...

Nigeria has the largest economy in Africa, at more than US$500 billion, and ranks 23rd in the world. A recent re-evaluation of Nigeria's true economic size doubled the previous estimate, and brought it well ahead of South Africa, which is a member (unlike Nigeria) of the G20 club for political as well as economic reasons. Nigeria's economy can be said to be quite diverse from one point of view, but heavily dependent on oil and gas at the same time. Oil and natural gas account for about 15% of Nigera's overall economy, but traditionally represent more than 90% of the country's exports and as...

The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session at @ThingsExpo, Ryan Bagnulo, Solution Architect / Software Engineer at SOA Software, focused on desi...

We certainly live in interesting technological times. And no more interesting than the current competing IoT standards for connectivity. Various standards bodies, approaches, and ecosystems are vying for mindshare and positioning for a competitive edge. It is clear that when the dust settles, we will have new protocols, evolved protocols, that will change the way we interact with devices and infrastructure. We will also have evolved web protocols, like HTTP/2, that will be changing the very core of our infrastructures. At the same time, we have old approaches made new again like micro-services...
