This blog’s main topic is Layer 4-7 testing. Some articles are specific to Spirent products (such as “How tos”), others cover network testing in general, and some others touch on subjects like security, new protocols, and so on.
I don’t hide the fact that I work for Spirent. That means I have a de facto bias towards Spirent Communications and will mention our products mostly, since this is the topic I know best. My views are my own only and do not necessarily reflect Spirent’s.
