Why is QoS and Especially Delay and Delay Variation Important ?
End-to-end delay budgets are a strict operator requirement
RAN transport delay is a significant contributor to end-to-end delay
Delay variation (jitter) is also important in dimensioning playout buffers
Hybrid approaches can be used to mitigate and protect delay-sensitive traffic
versus bulk, best effort
Convergence and phase stability of packet-based sync and timing protocols
depend on low delay and jitter effects on packet/timestamp arrivals
Ultimately, to fully leverage the packet-based RAN a range of traffic types
must be accommodated: legacy, sync, conversational, messaging, streaming,
best effort, OAM, etc.
Minimizing packet loss, delay and delay variation for certain traffic flows is crucial

Overview Of Traffic Management on SAR / SR
Traffic can be classified based on multi-field, DSCP, Dot 1p/q, timeslot, ATM
VC, port, etc.
Policing and queuing takes place based on classification
Queuing is scalable and flexible: strict priority, exhaustive and optionally
hierarchical
Traffic can be shaped towards the fabric
QoS is a key differentiator on 7705 SAR: sophisticated yet flexible —
configurable to fit the requirements of the PSN

creation and archival of test suites which can be scheduled to run at specific time intervals
(against all services relevant for mobile operators, such as ATM/TDM/Eth pseudowires),
collect results, compare the results against the specified thresholds (SLA metrics), and
return results in a form of report or raised alarm(s).
with the simple steps in the form of policy test creation, target selection, and schedule
selection, the tests can be made uniform across the network and available to all operators,
and run unattended, while their results will be reported.

Pure class-based queuing does not allow fairness
Current TDM and ATM backhaul solutions provide b/w per destination
IP backhaul can provide class-of-service distinction but where congestion occurs still need fairness and bandwidth policies for base stations

Dual Parented H-QoS: Per-class and Per-destination control
Combination of per class H-QoS with
the per ―subscriber‖ H-QoS provides
us with a class based scheduling
model that will allow
Each application to be prioritized based on
its level regardless of location or subscriber
Each subscriber will be defined with its own
rate for all of its applications.
service queues are dual-parented
Every queue will be parented by the class it
belongs to and that will define its priority
Every queue will also be parented by the
subscriber scheduler defining the maximum
amount of BW allowed for ALL of that
subscriber‘s queues.

SR/ESS QoS Hardware Features
The SR/ESS provides:
Per-service, per-class, ingress queuing and shaping features
Configurable ingress buffering up to 200 mSec at 10 Gbps
Egress buffering, up to 200 mSec at 10 Gbps
Up to 32 ingress queues per SAP; each queue has configurable CIR, PIR, CBS,
MBS, and HPO and forwarding class attributes*
8K ingress and 8K egress queues for SAP.
Three Major Components:
Traffic classification
Classification and marking
Buffer memory management
Default buffer allocations, queue attributes and WRED slope definitions

Hierarchical Scheduling
Suppose the CIR and PIR of three service ingress queues corresponding to
Premium, Expedited and Bulk services are configured as follows:
Premium: CIR = 10 Mbps, PIR = 10 Mbps
Expedited: CIR = 20 Mbps, PIR = 40 Mbps
Bulk: CIR = 0 Mbps, PIR = 100 Mbps
Under Basic scheduling, each of the queues can burst up to its specified PIR,
which means up to 150 Mbps can enter the service through the three queues.
Under Hierarchical Scheduling, a superior or “parent” scheduler can be
created for the Premium, Expedited and Bulk queues which limits the overall
rate of all the queues to (for example) 100 Mbps. With Virtual Scheduling,
customers will be able to send in any combination of Premium, Expedited and
Bulk traffic conforming to their specified PIR values and not to exceed 100
Mbps in total.
