sysServices { system 7 } read-only “A value which indicates the set of services
that this entity primarily offers.
The value 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

is added to the sum. For example, a node
which performs primarily routing functions
would have a value of 4 (2

a node which is a host offering application
services would have a value of 72 (2

). 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
