Monitoring Network Service Quality

Monitoring Network Service Quality

Network service quality refers to the quality of services running on a network. iPCA provides end-to-end service quality measurement and regional network service quality measurement. You can monitor the service traffic quality at a specified region through iPCA, implementing location of network faults.

Monitoring End-to-End Network Service Quality

eSight can monitor the end-to-end network service quality so that you can know the quality of a specified service flow on an end-to-end network, understand the health status of end-to-end network, and locate faults.

Process

Step

Description

1. Create a monitoring task.

To monitor end-to-end network service quality, you need to create a monitoring task according to the networking and device types on the network.

2. Monitor quality using alarms and packet conservation domain topology.

Maintenance personnel usually monitor network quality by checking alarms and topology. Alarms help you quickly learn about the health status of network resources and topology allows you to view details about network resources.

Creating a Monitoring Task
  • NTP has been configured to synchronize clock between devices. NTP ensures accuracy of iPCA quality measurement.
  • Only Huawei agile devices support iPCA. Agile devices refer to the devices supporting agile features. Currently, Huawei agile devices include S12700, S7700, and S5720HI. For details, see eSight Specification List.
  1. Choose Resource > Network > Business > iPCA Management from the main menu.

  2. Choose iPCA Management > Conservation Domain Measurement from the navigation tree on the left.
  3. Click Create.
  4. Set the parameters and click OK.

    Table 12-76 Parameter description

    Parameter

    Description

    Value

    MCP

    Collects and calculates the statistics data and shows measurement results in the topology view.

    Select a device as the MCP according to the network plan.

    Flow Direction

    Indicates the direction of the service flow to be monitored.

    • Forward
    • Bidirectional
    NOTE:

    If you select Bidirectional, both the source IP address and destination IP address need to be entered.

    Protocol

    Indicates the type of the protocol carrying the target flow.

    • TCP: services that use the TCP protocol, for example, data service, streaming media, cloud desktop. If you select TCP, both the source and destination ports need to be entered.
    • UDP: services that use the UDP protocol, for example, real-time video, IPTV, and voice. If you select UDP, the source and destination ports need to be entered.
    • All: all types of protocols.
    • Other: other types of protocols, except TCP and UDP.

    Source Port/Destination Port

    Indicates the source and destination ports of the target flow.

    You can enter a port number or a port number range.

    DSCP

    Indicates the value of a Differentiated Services CodePoint (DSCP). Different types of services pose different requirements on network delay and jitter. The DSCP value is used to ensure quality of high-priority services.

    The DSCP field has 64 values (0-63). The value 0 indicates the lowest priority and the value 63 indicates the highest priority.

    Source IP

    Indicates the source IP address of a target flow.

    • To measure quality of point-to-point service flows, set a single IP address for each of source and destination IP addresses.
    • To measure quality of multipoint-to-multipoint service flows, set an IP address range for each of source and destination IP addresses.
    • To measure quality of point-to-multipoint service flows, set a single IP address for source IP address and an IP address range for destination IP address.

    Destination IP

    Indicates the destination IP address of a target flow.

    NOTE:

    If you want to monitor end-to-end network service quality, scheme 3 is recommended. That is, set Protocol to All, enter the source and destination IP addresses, and select the flow direction.

  5. View the created tasks in the packet conservation domain list.

    You can also click in the Operation column next to a target task and select from the drop-down list box to view the status of the packet conservation domain in the topology.

Monitoring Quality Using Alarms and Packet Conservation Domain Topology

The monitoring process is as follows:

  1. View alarms that have been reported to know the health status of network resources.
  2. Perform the following operations according to the health status of network resources:
    • If there are reported alarms, check Location Info in the alarm list and Historical Data in the Operation column to find out the alarm cause.
    • If no alarm has been generated, view the physical topology to know details about the packet conservation domain. This information helps you take preventive measures before a fault occurs.

  1. View alarms that have been reported to know whether a service has lost packets in the packet conservation domain.

    Choose Fault > Current Alarms from the main menu.

  2. Perform the following operations according to the health status of the packet conservation domain.

    • If there are reported alarms, check Location Info in the alarm list and Historical Data in the Operation column to find out the alarm cause and handle the alarms.
    • If no alarm has been generated, view the packet conservation domain topology to know the packet loss rate of the current service.
      1. Choose Topology > Topology Management from the main menu.

      2. Choose Customize topology > iPCA Network-Level View in the topology tree on the left.
      3. View the packet loss rate in the packet conservation domain on the current page.
      4. To obtain detailed statistics, view the real-time or historical data of the packet conservation domain.

        Right-click the packet conservation domain and choose Query Real-time Data or Query Historical Data.

Monitoring Regional Network Service Quality

eSight can monitor the regional network service quality so that you can know the quality of a specified service flow on a regional network, and understand the health status of the regional network.
