|
This object denotes the PHB which is mapped to the traffic
class given by cggsnQosUmtsTrafficClass.
DS architecture is based on number of functional elements,
one of which is PHB. PHBs specify queuing, queue management
and scheduling characteristics that allow a means of
allocating buffer and bandwidth resources at each node among
the competing traffic streams.
The various DS PHBs include:
signalling - signallingClass(1)
The signalling class PHB is only used for the UMTS
signalling messages. This DS PHB does not apply to
any other IP data packets.
expedited forwarding - efClass(2)
The expedited forwarding PHB is used for providing
a low loss, low latency, low jitter, assured
bandwidth, end-to-end service through the DS domains.
Such a service appears to the endpoints like a
point-to-point connection, or a virtual leased line.
assured forwarding - afClass(3-6)
The assured forwarding PHB provides a means for a
provider DS domain to offer different levels of
delivery assurances for packets received from a
customer DS domain. Four assured forwarding classes:
afClass1, afClass2, afClass3 and afClass4 are defined,
where each AF class is in each DS node allocated a
certain amouont of forwarding resoources(buffer space
and bandwidth). IP packets are assigned into one or
more of these classes, according to the subscribed
service. Within each class the packets are marked
by a mobile subscriber, or by the provider DS domain,
with one of the three possible drop precedence
values. In case of congestion, the drop precedence
of a packet determines the relative importance of a
packet within the class. Packets in one class are
forwarded independently of the packets in another
class.
best effort - bestEffort(7)
This is the default PHB. The packets of this
aggregate are forwarded on an output link whenever
the link is not required to satisfy any other PHB.

|
Call Admission Control (CAC) is to ensure that network
resources are not oversubscribed to protect real-time traffic
such as voice (conversational) and video (streaming), etc.
Therefore before admitting a new PDP create, call admission
control will be performed to ensure there is sufficient
resource for the new PDP create request.
This table contains policy profiles (containing all the QOS
parameter needed for the PDP activation) which can be attached
to the one or more APN.
The SNMP entity adds a conceptual row to this table when
the user configures a policy profile.
The SNMP entity deletes a conceptual row from this table when
the user removes the policy profile. However, if there is
an APN associated with this policy, the conceptual row cannot
be deleted.
The SNMP entity modifies the conceptual row when the user
changes any QOS parameters of the profile. However, if there
are existing PDP contexts in the APN which is using this
policy, the maximum QOS parameter can only be changed to
greater or higher than previous configuration.
|
| cggsnUmtsQosCacTcTable |
.1.3.6.1.4.1.9.9.241.1.3.4.4 |
|
This table defines Maximum Bit Rate and/or Guranateed Bit rate
that can be allowed for each traffic class in both uplink and
downlink directions. For the IMS PDP context, this parameter is
taken from authorized QoS obtained from PDF.
The SNMP entity creates a conceptual row when the user
configures the MBR/GBR for a particular traffic class with
either uplink or downlink traffic type and there must be a
corresponding conceptual row existing in
cggsnUmtsQosCacPolicyTable.
The SNMP entity deletes the conceptual row(s), when the user
deletes the MBR/GBR config or the corresponding conceptual
row is deleted from cggsnUmtsQosCacPolicyTable. However, if
some PDP context is active in the APN using this policy,
then the conceptual row(s) cannot be deleted.
The SNMP entity modifes the conceptual row, when the user
changes the MBR/GBR value or the optional reject parameter.
However, if any PDP context is active in the APN using this
policy, then the MBR/GBR value can be changed to higher than
the previously configured.
|
| cggsnUmtsQosCacBWPoolTable |
.1.3.6.1.4.1.9.9.241.1.3.4.5 |
|
This table defines allocation of virtual bandwidth pool for
the traffic classes. Basically there are two types of bandwidth
pool, Physical & Virtual. Physical bandwidth is the egress
interface bandwidth. It is not supported and will not be
explained more.
Virtual bandwidth is user defined bandwidth. Virtual bandwidth
provides an easy and flexible way to implement bandwidth pool
for call admission control to avoid physical bandwidth
limitations. In contrast to per-interface based physical
bandwidth management, Virtual bandwidth management is per-APN
based, that is, each APN has its own pool to admit request.
To use this type of bandwidth, user needs to make assumption of
what interface type and total bandwidth of Gi and Gn in both
directions to allocate bandwidth for each class.
The SNMP entity creates a conceptual row when the user
configures the bandwidth pool with some bandwidth value in the
range described in cggsnUmtsQosCacBWPoolBWVal.
The SNMP entity deletes the conceptual row, when the user
deletes the bandwidth pool. However, if the bandwidth pool is
associated with an APN or if bandwidth is currently been
utilised, then the conceptual row cannot be deleted.
The SNMP entity modifes the conceptual row, when the user
changes the bandwidth value. However, if any PDP context is
active in the APN using this pool, then the bandwidth value
can be changed to higher than the previously configured.

bandwidth allocated for different traffic class per pool
must not exceed 100 percent or the absolute
value (4294967295).
The SNMP entity creates a conceptual row when the user
configures the bandwidth allocation for the traffic class
defined in cggsnQosBWPoolTrafClass and if the corresponding
conceptual row is present in cggsnUmtsQosCacBWPoolTable.
The SNMP entity deletes the conceptual row(s) when the user
unconfigures the bandwidth allocation for the traffic class
or the corresponding conceptual row is deleted from
cggsnUmtsQosCacBWPoolTable. However, if there are active PDP
in the APN using this pool, then the conceptual row cannot
be deleted.
The SNMP entity modifies the conceptual row when the user
changes the bandwidth allocation for a traffic class. However,
if there are active PDPs in the APN using this pool, then only
value greater than previous allocation is accepted.
