        QMOE Features – QoS
    •    Qwest QoS for MOE allows customers to prioritize their traffic into four classes of service. The four
         different levels are Priority 1, Priority 2, Priority 3 and Priority 4.
    •    QoS requires fiber and a Cisco ® 3750 at the premises.
    •    Customers who order QoS receive a minimum of 5 Megabits of P1 traffic. QoS is charged for every
         5 Megabit increment of P1, including the first increment. P1 traffic comes with a 99.999 percent
         service level agreement (SLA) goal.
    •    Customers can purchase a maximum of 50 mbps of P1 traffic per bandwidth profile.
    •    Customers who order QoS must specify which of eight templates applies for P2, P3 and P4 traffic.
         The template sets the limits for P2, P3 and P4 traffic. A customer cannot receive P2, P3 and/or P4
         QoS without ordering P1 traffic.
    •    Qwest will not bill to set up the first template for a QoS MOE circuit. However, customers will be
         billed a NRC for every subsequent template, or changes to existing templates.
    •    The amount of bandwidth allotted to P1 + P2 + P3 + P4 must equal 100 percent of the bandwidth
          –       P1:Supports VoIP applications and other highly critical applications. It is a near
                     real-time QoS supported by a low latency queue. A QoS service level
                     agreement is provided.
          –       P2: Supports interactive video applications.
          –       P3: Supports business data applications.
          –       P4: Default QoS for all other traffic that is not defined as P1, P2 or P3.

    QMOE Features – QoS (cont.)

    QoS SLA – 99.999 percent goal
    Measures the percentage of packets conforming to the committed bandwidth profile
    that are delivered across the core network, without being dropped or lost as a result
    of a fault within the virtual Ethernet network. The core network is defined as being
    from the Ethernet switch serving the customer’s A-end to the Ethernet switch serving
    the customer's B-end location.

    Thus, over any calendar month, the Qwest MOE network goal is to successfully
    deliver at least 99.999 percent of a customer’s packets across the core.

    QoS credit
    The service level availability credit will be based on a specific calendar month’s
    performance. The credit will apply for every increment of 5 Megabits of P1 traffic (i.e.,
    the quantity of QoS USOCs on the circuit). The SLA credit will apply to the monthly
    recurring P1 charges.

    The credit will equal 1/30th of the MRC for every 5 Megabits of affected P1 traffic.
    The maximum amount of credit provided in a given month will not exceed the total
    MRC for the affected service.

                                   (90 Mbps X 40%)

     QoS customer example:
    • Customer buys 100 Mbps and purchases 10 Mbps of P1. They are charged two increments of
      the QoS rate since each increment is 5 Mbps.
    • The customer then chooses Template 1 to distribute the remaining 90 Mbps of traffic in P2, P3
      and P4 priority levels. Template 1 sets P2 at 20 percent (of the 90 Mbps), P3 at 40 percent (of
      the 90 Mbps) and P4 at 40 percent (of the 90 Mbps).
    • If only 5 Megabits of P1 is sent, P2, P3 and P4 can use a combined 95 Megabits. If 15
      Megabits is sent as P1, 5 Megabits is discarded and P2, P3 and P4 can use 90 Megabits.

    QMOE Features – Multiple EVCs
     Multiple EVCs –
     An EVC connects two or more physical user-to-network interfaces (UNIs), i.e., locations, so the connection
     appears like a virtual private line. Each port provided by Qwest will come standard with the capability to provide
     one EVC. Customers may order more than one EVC per port; however, the maximum quantity is limited based
     upon availability. For each additional EVC, Qwest will bill a multiple EVC MRC.
     Requires fiber and a 3750 at the customer premises.
     Two port types are available that support multiple EVCs:
     • Service Provider Port
     • Service Multiplexing Port (pictured below)

    QMOE Features – Multiple EVC Charges
    • Each Service Multiplexing Port (SMP) or Service Provider Port (SPP)
      includes one EVC per port with no additional charge.
    • Each additional EVC to a SMP or SPP port type will carry an
      incremental MRC.
    • In the drawing example below, Location A is the SMP. EVC 1 is
      included with the SMP, EVC 2 will carry an incremental MRC for the
      multiple EVC.

    Service Provider Port - Requirements and Limitations
      • The service provider provides service to other end users.
         – Example: An Internet service provider (ISP)
      • The end customer is required to send untagged frames into QC MOE. Qwest
       adds a VLAN tag. That tag is negotiated and transmitted to the service provider.
      • VLANs or EVCs are used up on a one-to-one relationship; end users to service
      • If a customer controls both ends of the circuit and they’re simply asking Qwest to
       do routing on their behalf based on VLAN/EVC, they do not qualify for a service
       provider port.
      • Customers helping to deliver the service to another end user qualifies for a
       service provider port.
      • The total maximum number of EVCs allowed back to a service provider port is 50
       (this figure includes the one EVC that comes standard with the port).
      • Customers must be provisioned over fiber with a 3750 at the customer premises
       (this enhancement is not available over copper).

    Service Multiplexing Port - Requirements and Limitations
       • Available to all customers regardless of how they’re using the
       • Bottom line: anyone who doesn’t qualify for a service provider port
        can order a service multiplexing port.
       • The total maximum number of EVCs allowed back to a service
        multiplexing port is five (this figure includes the one EVC that comes
        standard with the port) .
       • Customers must be provisioned over fiber with a 3750 at the
        customer premises (this enhancement is not available over copper).

    QMOE Features – Protect Route (1)
      MOE Protect Route
      Protect Route provides a separate fiber facility path for the protection system
      between the serving wire center (SWC) and the company point of termination.* This
      added protection is provided by ensuring that backup electronics and two physically
      separate facility paths are used in the provisioning of the service. One primary (or
      working) service path is established between the SWC and the customer-designated
      premises. In addition, a protect path is provisioned between the customer-designated
      premises and the SWC via a company-designated alternate route. In the event the
      working facility or electronics fail, or the service performance becomes impaired, the
      facility automatically switches to the service protect path to maintain a near
      continuous flow of information between locations. Requires a 3750 at the customer

    QMOE Features – Protect Route (2)
     • Protect Route comes with an SLA should continuity between the
      customer-designated premises and SWC fail.
     • The SLA goal of 99.99 percent equates to four minutes and 20 seconds
      of downtime.
     • Multiple outages of less than four minutes and 20 seconds each will not be added
     • Credit of 1/30 MRC is paid for each occurrence where the outage exceeds four
      minutes and 20 seconds. Affected elements are the Protect Route MRC and
      the bandwidth profile MRC.
     • The maximum amount of credit provided in a given month will not exceed the MRC
      of affected elements for that month.

       – Qwest is reliant on the independents to buy, place, and configure
         the customer premises equipment. Sales and the project
         manager will have to work closely with the independent to
         coordinate the installation of this equipment.

    QMOE - Appendix

     What is the function of VLANs in the MOE network?
     • The function of a VLAN is to isolate and separate customer traffic
       across the shared MOE network by isolating the layer 2 Media Access
       Control (MAC) broadcast domains.
     • VLANs tag the customer’s traffic in the MOE network.
     • Qwest uses VLAN tags to allow multiple customers to share common
       network uplinks and Qwest infrastructure links while ensuring isolation
       and security of customer traffic.
     • VLANs have significance only within a metro region.
     • QC MOE uses the VLAN standards specified in IEEE 802.1q.

    QMOE – Traffic Partition Capability

     • Partitioning of different customers’ data traffic is done utilizing VLAN tags.
     • VLAN tagged frames are only allowed to terminate or originate on
       provisioned ingress/egress ports ensuring the security of traffic.
     • There are two different kinds of Ethernet frames that the customer may
       offer the MOE edge switch.
        – Native Ethernet
        – 802.1q tagged VLAN traffic
     • Tagged traffic is transported using Q-in-Q tag (outer tag) stacking, so
       customers may layer their own VLAN tag under the MOE transport tag
       (dependent on the type of access port ordered by the customer).

    QMOE Customer Access Port Types
         – Non-TLS
             • Native Ethernet
         – TLS
             • Native Ethernet and/or Customer VLAN Tagged frames
         – TLS Plus
             • Point-to-point only
             • Aggregated Ethernet Access ports (like N x T-1)
                 – LACP or PAgP (supported protocols)
         – Service Provider (SP)
             • Aggregates Non-TLS ports
             • Uses separate EVCs for each Non-TLS port
             • Limited to a total of 50 EVCs per SP port
         – Service Multiplexer (SM)
             • Aggregates Non-TLS and/or TLS ports
             • Uses multiple EVCs – can be multipoint
             • Limited to a total of 5 EVCs per SM port

    UNI and EVC Attributes
        • Customer VLAN ID/Tag Preservation
          – VLAN tags are not changed across the QC MOE Network

        • Service Multiplexing
          – Multiple EVCs on the same port

        • Bundling
          – Combining one or more customer VLANs into one Qwest EVC

        • Bandwidth Profile
          – Monthly Recurring Rate element (non-recurring rate element is the Port)

        • Layer 2 Control Protocols Tunneling
          – STP - spanning tree protocol
          – CDP – Cisco discovery protocol
          – VTP – Cisco VLAN trunking protocol
