What resources are intensively used in OSI model Layer 3 and what are the factors that slow that process down?

I found out several reasons: MTU mismatch on a link Unidirectional Traffic on a link A duplex mismatch High error rate in one or both directions layer 2 configuration issues ACL filtering with unintended consequences Security policy blocking traffic TTL setting is too low more than one subnet in a VLAN

Why do you ask? There is no OSI out there in the real world, except maybe buried in some telephone systems. Are they still teaching the OSI model 25 years after its demise? – user207421 Apr 07 '23 at 01:24
