Flow spec algorithm

1.  A flow specification lists the flows for a network along
with their performance requirements and priority
levels.
 Flow specifications can take one of three types:
 one-part, or unitary;
 two-part; or
 multi-part.

3.  A one-part flow-spec describes flows that have only
best-effort requirements/flows(BF).
 A two-part flow-spec describes flows that have
predictable requirements(P) and may include flows
that have best-effort requirements/flows(BF).
 A multi-part flow-spec describes flows that have
guaranteed requirements/flows(i) and may include
flows that have predictable requirements(P)and/or
best-effort requirements/flows(BF).

4.  It is a mechanism to combine these (capacity, delay &
RMA) performance requirements.
 To describe the composite performance for flow /
group of flows.

6.  For the predictable requirements , the flowspec has a
total capacity for best –effort flows CBE and another
capacity for p.redictable flows CP.
 for delay, the minimum delay is taken as delay
requirement Dp. And
 the maximum RMA Rpis taken as RMA Requirment.

8.  A multi-part flow spec is the most complex of flowspecs
 Building/Adding on a two –part flowspec to add
guaranteed requirements.
 Best Effort capacity along with predictable capacity,
delay, and RMA and each set (i) of guaranteed
performance requirement is added individually.
Shown as Ci Ri Di to the flowspec.
