I had a query on NSAP addresses (as applicable to the OSI world.) What is the significance of the network selector byte in the address? It would be helpful if you could explain with an example.
There is a great explanation here: https://searchnetworking.techtarget.com/definition/Network-Service-Access-Point.
Basically if an OSI end system has multiple NSAP addresses - which is frequently the case - they will typically differ only in the n-selector.
