Nanosecond Buffer Visibility with Hardware-Based Microburst Detection – Cisco Blogs
What Are Microbursts and Why Do They Matter? Ever wondered why a switch interface shows an average utilization of well below wire rate, and yet egress discards are incrementing? Most likely, that interface is experiencing microbursts. Often, when multiple input interfaces simultaneously receive traffic destined to a single egress interface – a so-called “incast” traffic pattern – no problem arises because the instantaneous receive rate is low enough that the output interface can handle the…
