Business Challenge: Everything Goes Mobile
The dynamic state of the business of service providers is quite apparent these days, and perhaps this is most evident for the mobility providers as everyone and everything goes mobile. All of their consumers, be they individual or business, are clamoring for new capabilities that can automate their business and simplify their lives. In addition there is a new class (or breed) of consumer – “Things”. Whether it is the connected car, city, bus, or kitchen appliances, “Things” are increasingly using the mobile network. Many of these new services and applications are readily available from “Over the Top” (OTT) providers that do not necessarily have any network upon which to deliver them. The OTT business model is designed for service creation agility, leaving it up to the operators to provide network access, quality of experience, and service assurance while managing the exploding demands for bandwidth and spectrum.

The news of high-profile targeted data center attacks has dominated security news recently. But data center attacks are even more prevalent than those headlines suggest. In fact, a survey conducted last summer by Network World suggests that 67 percent of data center administrators experienced downtime due to malware and related attacks in the previous 12 months.
A key challenge is that many of today's security solutions are simply not designed for the data center, with limitations in both provisioning and performance. The situation will likely get worse before it gets better as data center traffic grows exponentially and data centers migrate from physical, to virtual, to next-generation environments like Software-Defined Networks (SDN) and Application Centric Infrastructures (ACI).
I consider myself to be a reasonably intelligent individual. Well, perhaps "reasonably" is a debatable term; just ask my friends. Or my wife. (Then again, don't ask my wife.)
Reasonable or not, though, I've been trying to wrap my head around what all this "software defined" stuff is supposed to mean, and I have to confess it's been a bit circular: it's almost as if you have to already know the information you're trying to learn.
So where are the Napkin Dialogues written for people like me? Is everyone a super-genius programmer-cum-networker-cum-programmer and I just missed the boat? People are throwing around these "Open" terms left and right (e.g., OpenStack, OpenFlow, OpenDaylight, etc.) as if it's an "open" and shut case.
Well shut. The. Front. Door. I'm going to have to be on the receiving end of my own napkin then. For me, it's been feeling like I've been dropped into the middle of a maze with the lights turned off.

Yeah, kinda like that.
If you already 'get' this stuff, feel free to help a poor storage networking guy along in his journey, because I already know this iceberg goes all the way down.
To someone who is familiar with tried-and-true Data Center designs, I'm just having a hard time getting my head wrapped around 1) getting from here to there, and 2) just where there is! Read More »
A subject very close to my heart at the moment is what skills I will need to have in order to support the Next Generation of Software Defined and Application Centric networks.
It is of no surprise that Networking like most other towers in IT has embraced abstraction as the way forward to provide levels of flexibility and agility never before seen in the Network.
What is perhaps a bit of a surprise, is the speed in which these new concepts are being developed and deployed. It seems like only last year terms like SDN were still viewed as "Way down the line" technologies. But here we are at the start of Q2 2014 and it seems like if you don’t already have an SDN plan you’re already behind.
So what skills will we need in order to design, support and deploy these new networks? Read More »
Many of the existing switch and wireless infrastructures that were deployed 5 or more years ago were not designed for BYOD, pervasive mobility, advanced security, SDN and more. Let us look at these trends and the benefits of upgrading the network infrastructure to the latest switching and wireless products.
BYOD and Mobility
There are multiple dimensions in which BYOD and mobility are pressuring the existing network. An average user now has 3x more devices. A company of 1,000 users seems like a company of 3,000 users. And, Internet of Things devices like sensors, CCTVs, and building automation are being connected to the network. Yesterday’s network cannot sustainably handle the exponential growth of these devices and applications. Upgrade to the latest switches and wireless infrastructure will give you more performance in terms of higher switching capacity, converged wired-wireless access & more processing power to handle the growth of devices/apps. The benefits are network can scale easily to support the influx of mobile & connected devices and their applications and your users get the same excellent experience whether wired or mobile.
