Create traffic descriptor (data)
Description
Indicates the Traffic codification, according to
international standard conversion:
best Effort Service - serves Low priority traffic,
which relies on transport layer protocol (per OSI
stack) to recover from loss and tolerates large
delay; e.g. E-mail and file transfer applications.
Best Effort denotes BW (PIR > CIR = 0 in
100kbps increments), which may or may not be
available per network operator's reservation for
Best Effort policy. It may therefore be
unavailable under congestion conditions
backGroundService
regulatedService - serves Medium priority
traffic, which relies on transport layer protocol
(per OSI stack) to recover from occasional loss
and requires moderate delay; e.g. client–server
applications. Regulated service denotes BW
(PIR > CIR >0 in 100Kbps increments), which
may be overbooked per network operator's
overbooking policy. The portion of bandwidth
between CIR and PIR (aka EIR) may therefore
be partially available under congestion
conditions.
regulatedService1
regulatedService3
regulatedService4
guaranteedService - serves High priority traffic
for mission critical applications that require
loss–less delivery and minimal delay.
Guaranteed SLA denotes BW (CIR = PIR > 0 in
100Kbps increments), that is always available
regardless of any congestion conditions. Traffic
delivered using Guaranteed BW, is policed to the
CIR value with a burst window equal to the CBS.
guaranteedService2
This is the normal medium rate (expressed in
kb/sec) of the data flow (Effective Bandwidth)
and it ranges from 0 to PIR value. It can be set
only if the regulatedService has been selected;
in bestEffortService case it is set to 0 by the
system; in guaranteedService case it is set equal
to PIR value
