FIELD DESCRIPTION
Services This is a number that indicates the set of services offered. The number is a sum.
This sum initially takes the value zero, Then, for each layer, L, in the range 1 through 7, that this
node performs transactions for, 2 raised to (L - 1) is added to the sum. For example, a node that
performs primarily routing functions would have a value of 4 (2^(3-1)).
In contrast, a node that is a host offering application services would have a value of 72 (2^(4-1) +
2^(7-1)). Note that in the context of the Internet suite of protocols, values should be calculated
accordingly: layer functionality 1 physical (e.g., repeaters) 2 datalink/subnetwork (e.g., bridges) 3
internet (e.g., IP gateways) 4 end-to-end (e.g., IP hosts) 7 applications (e.g., mail relays) For systems
including OSI protocols, layers 5 and 6 may also be counted.
