sysServices A value that indicates the set of ser-
vices 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 - 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:
Layer 1 - physical (e.g., repeaters)
Layer 2 - datalink/subnetwork (e.g.,
bridges)
Layer 3 - internet (e.g., IP gateways)
Layer 4 - end-to-end (e.g., IP hosts)
Layer 7 - applications (e.g., mail
relays)
* For systems including OSI proto-
cols, Layers 5 and 6 may also be
counted.
Read-only The 1900 MIU shelf will per-
form Layer 1 (physical) and
Layer 2 functionality only. So
the number would be 2^(1-1) +
2^(2-1) = 3
