It is an architectural perspective and, more importantly, a mindset. ...

Network Infrastructure Product Selection: Strategic Criteria and Field Experiences How to evaluate Switch, Firewall, and AP beyond the datasheet Most enterprise network projects start at the same point: product selection. And most of the time, they fail at the same point: products not working together. Because what we call a “core network” is not just three boxes (switch, firewall, access point) sitting side by side; it is about these three boxes carrying an identity together, generating segments together, enforcing policies together, and most importantly, sustaining operations together. ...
