Want affordable SDN products? Check the secondary market

Frankly (no pun intended), I have to admit that I’m growing increasingly frustrated with certain trends in networking.For example, it’s not that I don’t like the dream or idea of software-defined networking (SDN) — it’s not that I don’t think it’s superior to the older way of setting up or monitoring a network. It’s just that I’m becoming increasingly concerned that small- to medium-size enterprises (SMEs) won’t be able to keep up. And the media that follows this trend isn’t really brining to light the extreme cost of some of these systems.Pricewise, many of the product lines are intended for large networks. There's no way that a smaller company could even begin to afford them. For example, one trainer told me that a certain SDN product was scaled to start at 500 site deployments!!To read this article in full, please click here

How Cisco’s Multigigabit Technology can increase network speeds

If you remember, in a previous Switch IT Up blog post I referenced Wireless AC and Wave 2 — some of the things that we could expect and some of the problems we could run up against. Things like having enough bandwidth to our APs to support a 6.8 gig connection.So, what can be done about that?Well, in 2015, Cisco introduced its Catalyst Multigigabit Technology, along with a new group of products, that address that issue and allow users to get more than just that 1 gig speed that most people have in their closets or in their infrastructure. How can users leverage that and still use their preexisting infrastructure rather than having to rip everything out and replace it?To read this article in full, please click here

5 reasons to buy refurbished Cisco equipment

It’s a pretty common scenario. You’re considering implementing Cisco hardware in your infrastructure, and you talk to a vendor who pushes a shiny, new, cutting-edge solution on you.It’s impressive, this bleeding-edge solution — it has all sorts of bells and whistles (whether your business plan can make smart use of them or not) and it comes with a nice, healthy price tag.So, you’re left with a really difficult question. Should you stretch your already thin budget with a solution that may actually be overkill for your needs? Or do you have options[ Read also: 80/20 rule of network equipment: Stay on budget and innovate. | Get daily insights: Sign up for Network World newsletters. ] 5 things to consider when buying network hardware Keep these five factors in mind as you consider how to proceed with your Cisco hardware solutions because that vendor who thinks you should buy new probably doesn’t want you to know them.To read this article in full, please click here

Does the Cisco 4000 router series redefine the traditional role of routers?

Last month it was Catalyst 9000 switches, and this month its routers. Yes, my project engineering staff have had a surprising amount of inquiries regarding routers.Routers vital to enterprise networks When looking at distribution for an enterprise network, well-planned routing is the key to success. Routers can be absolutely vital for networks, as they connect a large amount of worksites within one large, umbrella-like network. At the enterprise level, they provide redundant paths, connect ISPs, and can translate data between different media.To read this article in full, please click here

Requests for Cisco Catalyst 9300 are up … what’s the intent?

My project engineering staff has been getting more and more information requests for Cisco’s new line of Catalyst 9000 switches, especially the 9300 switch. That has me wondering why.Cisco touts the Catalyst 9300 Series as the next generation of the industry's most widely deployed stackable switching platform that’s built for security, the Internet of Things (IoT), and cloud computing. It’s part of a line of network switches that form the foundation for Cisco's Software-Defined Access, its leading enterprise architecture.One reason for the increased interest could be Cisco’s recently announced new intent-based networking system. Cisco believes that by adopting an intent-based approach, networks will be able to deliver a solution that introduces an onslaught of applications and devices that provide greater efficiency and address new security threats.To read this article in full, please click here

Is Cisco’s Mobility Express right for you?

One of the hottest topics on the minds of our customers for 2018 continues to be their wireless infrastructure. As WLAN 802.11ac wave 2 devices becoming mainstream, Cisco has placed a stake in the ground claiming to be the “value leader.”Cisco's solution to accomplish this is Mobility Express, designed to help companies easily set up wireless LAN (WLAN) networks. What exactly is Mobility Express? And is it right for you?What is Mobility Express? Mobility Express is the ability to use an access point (AP) as a controller. That means a lightweight network without a controller box. Instead one of the APs on the network acts as the controller. Here is how Cisco describes it:To read this article in full, please click here

Can Wave 2 handle the wireless tsunami heading toward us?

There seems to be a shift in our industry from wireless N to AC, as we have seen large leaps forward in bandwidth and client saturation handling. With more wireless options going in the workplace, widespread connectivity continues to rise and wireless requirements are becoming greater and greater.Now, with Wave 2 becoming more common, is AC really able to handle the tsunami-like wave of wireless internet requests to meet this growing demand?Also on Network World: REVIEW: Early Wave 2 Wi-Fi access points show promise There's only one way to find out. We need to step out of the comfort zone provided by past wireless technologies and expand the idea of what wireless is capable of providing to meet these demands.To read this article in full or to leave a comment, please click here

The King is dead?! Heck, no!

It’s been about a year and a half since I asked the question in this blog, “Is the Cisco 6500 Series invincible?” I believe enough time has passed and that I should revisit that question — especially since people in the industry have been talking, tweeting and writing about the demise of the venerable Catalyst 6500 chassis family for years. But don’t worry, the King is not dead because Cisco is having none of that! + Also on Network World: 4 resources to find free Cisco skills and certification labs + Aside from being a major revenue stream for Cisco, the 6500 chassis family remains a solid platform that the company has made extensible by creating the Catalyst 6800 family. To read this article in full or to leave a comment, please click here

Is the Cisco 6500 Series invincible?

The Cisco 6500 Series has proven itself time and time again to be a mainstay in the networking industry. Cisco has done a commendable job with continued enhancements to ensure that the industry’s golden child maintains relevance. If this is the case, why do IT professionals still fear its supposedly impending obsolescence and feel pressure to upgrade to newer models? Let’s just say rumors of its demise are greatly exaggerated.As the industry moves toward 10/40Gig and higher, the need for bandwidth and port density only increases. Software-defined networking (SDN), while certainly worthy of consideration, may not be the best option for all organizations just yet. However, the need for high-speed switching connectivity and robust services remains a concern for the here and now. Enter: The Cisco 6500 Series.To read this article in full or to leave a comment, please click here
