| Description | The Delay parameter at each service element
should be set to the maximum packet transfer
delay (independent of bucket size) through the
service element. For instance, in a simple
router, one might compute the worst case amount
of time it make take for a datagram to get
through the input interface to the processor,
and how long it would take to get from the pro-
cessor to the outbound interface (assuming the
queueing schemes work correctly). For an Eth-
ernet, it might represent the worst case delay
if the maximum number of collisions is experi-
enced.
The Delay term is measured in units of one mi-
crosecond. An individual element can advertise
a delay value between 1 and 2**28 (somewhat
over two minutes) and the total delay added all
elements can range as high as (2**32)-1.
Should the sum of the different elements delay
exceed (2**32)-1, the end-to-end delay should
be (2**32)-1. |
