  • Page 24: Qos Overview

    There is still no guarantee of service quality. The guarantee of service quality is what distinguishes QoS from CoS. CoS is an element of overall QoS. By using the traffic management features of the 7705 SAR, network engineers can achieve a QoS for their customers. Multiprotocol Label Switching (MPLS) provides a predetermined path, while policing, shaping, scheduling, and marking features ensure that traffic flows in a predetermined and predictable manner.

  • Page 25

    7705 SAR will be contained within QoS boundaries associated with that service and the general QoS parameters assigned to network links. The 7705 SAR is designed with QoS mechanisms at both egress and ingress to support different customers and different services per physical interface or card,...

  • Page 26: Egress And Ingress Traffic Direction

    As an example, if there is a group of Node Bs connected to a 7705 SAR node, one QoS policy can be applied to all services of the same type, such as High-Speed Downlink Packet Access (HSDPA) offload services.

  • Page 27: Ring Traffic

    This section (QoS Overview) uses the term access, and the following sections (beginning with QoS Policies Overview) use the term service. Figure 1 Egress and Ingress Traffic Direction 7705 SAR Access Ingress Network Egress Access Fabric Network Customer Access Egress...

  • Page 28: Forwarding Classes

    Queues can be created for each forwarding class to determine the manner in which the queue output is scheduled and the type of parameters the queue accepts. The 7705 SAR supports eight forwarding classes per SAP. Table 2 shows the default mapping of these forwarding classes in order of priority, with Network Control having the highest priority.

  • Page 29

    Quality of Service Guide QoS and QoS Policies The traffic flows of different forwarding classes are mapped to the queues. This mapping is user-configurable. Each queue has a unique priority. Packets from high-priority queues are scheduled separately, before packets from low-priority queues.

  • Page 30: Scheduling Modes

    Access Egress Queuing and Scheduling 3.1.5 Intelligent Discards Most 7705 SAR systems are susceptible to network processor congestion if the packet rate of small packets received on a node or card exceeds the processing capacity. If a node or card receives a high rate of small packet traffic, the node or card enters overload mode.

  • Page 31

    Intelligent discards during overload ensures priority-based handling of traffic and helps existing traffic management implementations. It does not change how QoS-based classification, buffer management, or scheduling operates on the 7705 SAR. If the node or card is not in overload operation mode, there is no change to the way packets are handled by the network processor.

  • Page 32: Buffering

    3.1.6.1 Buffer Pools The 7705 SAR supports two types of buffer pools that allocate memory as follows: • reserved pool—represents the CBS that is guaranteed for all queues. The reserved pool is limited to a maximum of 75% of the total buffer space.

  • Page 33: Cbs And Mbs Configuration

    CBS buffer limit for the queue was considered reached when half of the available buffers were in use. In Release 8.0 of the 7705 SAR, the CBS is no longer divided by two. Instead, the extra buffers are added to the queue count when enqueuing, and are removed from the queue count when the multicast traffic exits the queue.

  • Page 34: Buffer Unit Allocation And Buffer Chaining

    Packetization buffers and queues are supported in the packet memory of each adapter card or platform. All adapter cards and platforms allocate a fixed space for each buffer. The 7705 SAR supports two buffer sizes: 512 bytes or 2304 bytes, depending on the type of adapter card or platform.

  • Page 36

    QoS and QoS Policies Quality of Service Guide Note: 1. The 7705 SAR-X has three buffer pools. Each block of ports (MDA) has its own buffer pool. 3.1.6.3.1 Advantages of Buffer Chaining Buffer chaining offers improved efficiency, which is especially evident when smaller packet sizes are transmitted.

  • Page 37: Shaped And Unshaped Saps

    Quality of Service Guide QoS and QoS Policies Figure 3 Figure 4 illustrate per-SAP aggregate shapers for access ingress and access egress, respectively. They indicate how shaped and unshaped SAPs are treated. H-QoS is not supported on the 4-port SAR-H Fast Ethernet module. 3.1.7.1 Shaped and Unshaped SAPs Shaped SAPs have user-configured rate limits (PIR and CIR)—called the aggregate...

  • Page 38

    This aggregate CIR is applied to all the 4-priority SAPs as a group, not to individual SAPs. In addition, the aggregate CIR is configured differently for access ingress and access egress traffic. On the 7705 SAR-8 and 7705 SAR-18, access ingress is configured in the config>qos>fabric-profile context. On the...

  • Page 40: H-qos Example

    A typical example in which H-QoS is used is where a transport provider uses a 7705 SAR as a PE device and sells 100 Mb/s of fixed bandwidth for point-to-point Internet access, and offers premium treatment to 10% of the traffic. A customer can mark up to 10% of their critical traffic such that it is classified into high-priority queues and serviced prior to low-priority traffic.

  • Page 41: Per-vlan Network Egress Shapers

    QoS for Gen-3 Adapter Cards and Platforms. The 7705 SAR supports a set of eight network egress queues on a per-port or on a per-VLAN basis for network Ethernet ports. Eight unique per-VLAN CoS queues are created for each VLAN when a per-VLAN shaper is enabled. When using per-VLAN shaper mode, in addition to the per-VLAN eight CoS queues, there is a single set of eight queues for hosting traffic from all unshaped VLANs, if any.

    − A maximum of eight per-VLAN shapers can be configured on an 8-port Ethernet Adapter card, version 2. − On an 8-port Ethernet Adapter card, version 2, installed in an 7705 SAR-18, when a Fast Ethernet port is configured as a network port with profile scheduler mode, the number of per-VLAN shapers supported on the card is reduced by one.

    On all 7705 SAR fixed platforms (with the exception of the 7705 SAR-X), when a shaper policy is assigned to an Ethernet MDA for access ingress aggregate shaping, it is automatically assigned to all the Ethernet MDAs in that chassis. The shaper group members contained in the shaper policy span all the Ethernet MDAs.

A network QoS policy defines ingress, egress, and ring handling of QoS on the network interface.

    Quality of Service Guide Network queue policies are identified with a unique policy name that conforms to the standard 7705 SAR alphanumeric naming conventions.

    If the flow rate is above the threshold, the transmitted packet is internally marked out-of-profile. All 7705 SAR queues support the concept of in-profile and out-of-profile. The network QoS policy applied at network egress determines how or if the profile state is marked in packets transmitted into the network core.

  • Page 147: Peak Information Rate

    When defining the CIR for a queue, the value specified is the administrative CIR for the queue. The 7705 SAR maps a user-configured value to a hardware supported rate that it uses to determine the operational CIR for the queue. The user has control over how the administrative CIR is converted to an operational CIR if a slight adjustment is required.

    QoS and QoS Policies Quality of Service Guide The high-priority-only buffers for network queues are defined within network queue policies based on the forwarding class. High-priority-only traffic for a specific traffic class is marked as in-profile either on ingress classification or based on interpretation of the QoS markings.

  • Page 151: Queue Counters

    3.7.6.9 Queue Counters The 7705 SAR maintains extensive counters for queues within the system to allow granular or extensive debugging and planning; that is, the usage of queues and the scheduler used for servicing a queue or packet is extremely useful in network planning activities.

  • Page 152: Rate Limiting

    3.7.6.11 Rate Limiting The 7705 SAR supports egress-rate limiting and ingress-rate limiting on Ethernet ports. The egress rate is set at the port level in the config>port>ethernet context. Egress-rate limiting sets a limit on the amount of traffic that can leave the port to control the total bandwidth on the interface.

  • Page 153: Slope Policies (wred And Red)

    QoS and QoS Policies 3.7.7 Slope Policies (WRED and RED) As part of 7705 SAR queue management, policies for WRED and/or RED queue management (also known as congestion management or buffer management) to manage the queue depths can be enabled at both access and network ports and associated with both ingress and egress queues.

  • Page 154

    QoS and QoS Policies Quality of Service Guide Referring to Figure 24, one WRED slope curve can manage discards on high-priority traffic and another WRED slope curve can manage discards on low-priority traffic. The minT, maxT and maxDP values configured for high-priority and low-priority traffic can be different and can start discarding traffic at different thresholds.

  • Page 155: Wred Minthreshold And Maxthreshold Computation

    The system-minT must be the absolute closest value to the minT that satisfies the formula below (2^x means 2 to the exponent x): system-maxThreshold – system-minThreshold = 2^x Note: The 6-port Ethernet 10Gbps Adapter card and the 7705 SAR-X Ethernet ports use payload-based WRED (also called byte-based WRED); see Payload-based WRED.
