What OSI layer are we discussing?

• samstave 7y ago
  Interestingly that you say this; we need an additional layer called layer 8. As app is 7 but we have grown beyond the seven into meta layers of service types which have become the favric of how we operate... such as email, txt, chat etc to keep all other aspects of infra up and running.

    the OSI model is not a truthful representation of the different layer of networking. Things get messy between layer 2 and 3 (ARP for instance?). Also, everything above layer 4 is a enormous mess, considering that stuff is usually happening at the application itself anyways. There are network protocols which have proper OSI seperation, but they are rarely used. (IS-IS in combination with CLNS for instance).

      Knowledge atrophy is a serious thing... i used to be deeply skilled in all of that but attention is where the heart is... so ive literally forgotten so much abt networking over the years. A failure of mine was to not keep a project portfolio runbook which i could look back upon. Imagine a system where all your status reports were logged and searchable - that would be move valuable than linkedin...
