Comparing Apples to Oranges: The Meaning of Bandwidth.

Part of my role in the Juniper Networks Routing platform team is to review and decipher marketing announcements from our competitors. Just recently I stumbled upon one such announcement which inspired me to create this blog and share with you my observations on bandwidth [BW] measurements. My objective is to bring awareness to customers and sales engineers of how to correctly understand and approach network BW capacity. The following blog represents my personal opinion and not necessarily that of Juniper Networks.

Let’s get going…


The marketing announcement that sparked my interest in this topic was an advertisement publicizing “the industry’s first 2 Tbps line card.” My initial reaction was something like: Really? I hate to be the bearer of bad news, but this is a little late. The new benchmark is 3 Tbps since Juniper’s release of the PTX FPC3 on March 11th . However, I decided to sit down, take a sip of espresso, and try to understand the methodology behind this announcement.
