Not all network engineers understand the impact of interface errors on TCP performance. Interface errors can cause a BIG impact, although it may not be intuitive at first glance. We recently pointed out some interfaces with extremely high errors to a customer. We mentioned that the links with the highest…

've always looked at percentage of interface errors as an indicator of which interfaces I should examine. What did I know? Not enough, as it turns out. I've been working with customers on application performance, as you might have guessed from the series of recent blogs on the topic of…

Here is a recap of articles I posted in August to my blog at Netcordia: “Quick Network Redundancy Test” describes why and how you should test the network redundancy that [...]

Good network engineers know about TCP performance over Long, Fat Networks (LFNs – see RFC1323) and how to use bandwidth, delay, and window size to calculate the maximum throughput of [...]
