  • Page 90: Quality Of Service (Qos)

    QoS will provide the best results. The figure below shows the basic flow of PTP 820S’s QoS mechanism. Traffic ingress (left to right) is through Ethernet or radio interfaces on the “Ingress path.” Based on the services model, the system determines how to route the traffic.

  • Page 91: Figure 54 Standard Qos And H-Qos Comparison

    (service bundles), from a total 2K queues. In H-QoS mode, PTP 820S performs QoS in a hierarchical manner in which the egress path is managed on three levels: ports, service bundles, and specific queues. This enables users to fully distinguish between streams, therefore providing a true SLA to customers.

  • Page 92: Figure 55 Hierarchical Classification

    QoS on the Ingress Path Classification PTP 820S supports a hierarchical classification mechanism. The classification mechanism examines incoming frames and determines their CoS and Color. The benefit of hierarchical classification is that it provides the ability to “zoom in” or “zoom out”, enabling classification at higher or lower levels of the hierarchy.

  • Page 93: Figure 56 Classification Method Priorities

    Chapter 4: Feature Description Ethernet Features PTP 820S performs the classification on each frame that ingresses the system via the logical interface. Classification is performed step by step from the highest priority to the lowest priority classification method. Once a match is found, the classifier determines the CoS and Color decision for the frame for the logical interface-level.

The TrTCM rate meter can change a frame’s CoS settings based on CIR/EIR+CBS/EBS, which makes the rate meter mechanism a key tool for implementing bandwidth profiles and enabling operators to meet strict SLA requirements.

  • Page 100 QoS on the Egress Path Queue Manager The queue manager (QM) is responsible for managing the output transmission queues. PTP 820S supports up to 2K service-level transmission queues, with configurable buffer size. Users can specify the buffer size of each queue independently. The total amount of memory dedicated to the queue buffers is 2 Gigabits.

  • Page 101: Figure 58 Ptp 820S Queue Manager

    This operation is integrated with the queue occupancy level. The 2K queues share a single memory of 2 Gbits. PTP 820S enables users to define a specific size for each queue which is different from the default size. Moreover, users can create an over- subscription scenario among the queues for when the buffer size of the aggregate queues is lower than the total memory allocated to all the queues.

  • Page 102: Figure 59 Synchronized Packet Loss

    Chapter 4: Feature Description Ethernet Features The queue size is defined by the WRED profile that is associated with the queue. For more details, WRED on page 4-70. WRED The Weighted Random Early Detection (WRED) mechanism can increase capacity utilization of TCP traffic by eliminating the phenomenon of global synchronization.

  • Page 103: Figure 61 Wred Profile Curve

    To deal with this, PTP 820S enables users to define up to 30 WRED profiles. Each profile contains a Green traffic curve and a Yellow traffic curve. These curves describe the probability of randomly dropping frames as a function of queue occupancy.
