Watch Out Cisco. Huawei’s Coming!

In this Gigaom.com piece, Stacey talks about the arrival of Huawei in America.

Huawei had a rocky start with widely known hardware failures [...]

I’ve been doing some research into Ethernet and the use of Jumbo frames for some content I’ve been writing and come across something interesting. The documents state that Jumbo frames can only be used on Full Duplex Ethernet connections.

Musing: Difference Between Success and Not Failing

roject scopes means that the smallest possible money is spent to achieve the least acceptable outcome. That is, the scope of the project is defined as the smallest possible work to achieve the goal.The goal is often researched, analysed, and reviewed until it is reduced to as small as it can be. That is, the “least acceptable” goal for the business.

Network Evolution and Hierarchy of Needs

I’ve often pondered the stages of Network Deployment and Integration within companies – how they progress from the one stage of network complexity to the next. And if you work at enough different organisations you realise that they all companies operate in similar ways, and have similar adoption of Networking. From an IT infrastructure perspective, most organisations use the same basic service models.

In a sense, networking provides the human equivalent of the nervous system which allows the myriad corporate organs to communicate, signal and co-operate. This, of course, leads to consideration of the psychological perception of Networking.

In a recent blog, Alvaro Retana from HP (co-author of a number of outstanding textbooks including Cisco Press with Russ White and some others that are not vendor specific and Cisco CCAr/CCDE etc) wrote a blog post that is similar to something in my “to finish” list where he takes the Maslows Hierarchy of Needs and adapts it to how Networks are part of the corporate Hierarchy of Needs.

Musing: Targeted Recruitment Means Bows and Boobs

In my ongoing project to laugh heartily at marketing people but especially Cisco marketing people, I give you the Cisco Strategic Recruitment Solution.

Check out the picture on this brochure. That’s right. Nothing says “Strategic Recruitment” like the picture of a young woman, in a skimpy top, boobs to the front, and pulling an arrow on a bow.
