I hava a cold. Did I fail?

When a person gets ill, say from a cold like the one I have right now, we tend to slow down, maybe have trouble focusing, or otherwise performing certain tasks. Clearly we function, but not as well as we would … Continue reading

It’s all about Reliability

If you consider yourself an engineer, think about what you do in a very broad sense. Engineering is all about applying scientific discovery and making it practical, useful, and widely used. If you are an Electrical Engineer, for example, then … Continue reading

The What and How of Network Modeling

I often get asked to describe what I do and how I do it, especially when it comes to network modeling. The other day, that need became urgent. With the pressure on to come up with a description, here is … Continue reading

Capacity Management, Failure Mitigation, and Where to Start?

Standard mitigation tools are a great place to start with Capacity Management, just like any failure mitigation need. As a telecommunications and IT consultant, we’re often called upon to solve problems. I remember some of my early training that suggested … Continue reading

FMECA with Wireshark

Returning from Sharkfest, I found that my laptop’s configuration must have changed. The laptop, running Windows 7 home version, was now not able to see a few of the non-windows machines on my network, including the NAS. Assuming the cause … Continue reading

Network availability and performability modeling tricks

I read a lot, and I mean a lot, of network reliability, availability, and performability papers. The ones we publish in the IEEE Transactions on Reliability, I read multiple times. So there are a lot of relationships that go unnoticed, … Continue reading

Otherwise coherent networks become incoherent when capacity is concerned

See the network in Figure 1 below. Source node 1 fails, which from a pure availability perspective disrupts only traffic originating or terminating at node 1 because all other nodes can still communicate. So a coherent network (as is the … Continue reading
