Example for Configuring IP FPM End-to-End Performance Statistics Collection

Example for Configuring IP FPM End-to-End Performance Statistics Collection

This section provides an example for configuring IP Flow Performance Monitor (FPM) end-to-end performance statistics collection.

Networking Requirements

Various value-added services, such as IPTV, video conferencing, and voice over IP (VoIP) are widely used on networks. As these services rely heavily on high speed and robust networks, link connectivity and network performance are essential to service transmission.
  • When voice services are deployed, users will not detect any change in the voice quality if the packet loss rate on links is lower than 5%. If the packet loss rate is higher than 10%, the voice quality will deteriorate significantly.

  • Real-time services, such as VoIP, online games, and video conferencing, require a delay lower than 100 ms, or even 50 ms. As the delay increases, user experience worsens.

To meet users' service quality requirements, carriers need to promptly measure the packet loss rate and delay so that they can quickly respond to resolve network issues if the service quality deteriorates.

The IPRAN network shown in Figure 2-9 transmits voice services. Voice flows are symmetrical and bidirectional, and therefore one voice flow can be divided into two unidirectional service flows. The forward service flow enters the network through the UPE, travels across SPE1, and leaves the network through the NPE. The backward service flow enters the network through the NPE, also travels across SPE1, and leaves the network through the UPE.

To meet users' service quality requirements and take measures when service quality deteriorates, configure IP FPM end-to-end performance statistics collection to monitor the packet loss and delay of the links between the UPE and NPE in real time.

Configuration Roadmap

The configuration roadmap is as follows:
  1. Configure an IP address and a routing protocol for each interface so that all provider edge devices (PEs) can communicate at the network layer. This example uses Open Shortest Path First (OSPF) as the routing protocol.

  2. Configure Multiprotocol Label Switching (MPLS) functions and public network tunnels. In this example, RSVP-TE tunnels are established between the UPE and SPEs, and Label Distribution Protocol (LDP) LSPs are established between the SPEs and between the NPE and SPEs.

  3. Create a VPN instance on the UPE and NPE and import the local direct routes on the UPE and NPE to their respective VPN instance routing tables.

  4. Establish MP-IBGP peer relationships between the UPE and SPEs and between the NPE and SPEs.

  5. Configure the SPEs as route reflectors (RRs) and specify the UPE and NPE as RR clients.

  6. Configure VPN FRR on the UPE and NPE.

  7. Configure the Network Time Protocol (NTP) to synchronize the clocks of the UPE, SPE1, and the NPE.

  8. Configure proactive packet loss and delay measurement on the UPE and NPE to collect packet loss and delay statistics at intervals.

  9. Configure the packet loss and two-way delay alarm thresholds and clear alarm thresholds on the UPE.

Data Preparation

To complete the configuration, you need the following data:
  • IP address of each interface listed in Table 2-1

  • Interior Gateway Protocol (IGP) protocol type, process ID, and area ID

  • Label switching router (LSR) IDs of the UPE and SPEs

  • Tunnel interface names, tunnel IDs, and tunnel interface addresses (loopback interface addresses) for the bidirectional tunnels between the UPE and SPEs

  • Tunnel policy names for the bidirectional tunnels between the UPE and SPEs and tunnel selector names on the SPEs

  • Names, route distinguishers (RDs), and VPN targets of the VPN instances on the UPE and NPE

  • UPE's NTP stratum (1); clock synchronization interval (180s) for the UPE, SPEs, and the NPE; offset (50s) between the clock server and client; maximum polling time (64s)

  • UPE's DCP ID and MCP ID (both 1.1.1.1); NPE's MCP ID (4.4.4.4)

  • IP FPM instance ID (1) and statistical period (10s)

  • Forward target flow's source IP address (10.1.1.1) and destination IP address (10.2.1.1); backward target flow's source IP address (10.2.1.1) and destination IP address (10.1.1.1)

  • Measurement points (TLP100 and TLP310)

  • Loss and delay measurement flags (respectively the third and fourth bits in the ToS field of the IPv4 packet header)
    NOTE:
    Before you deploy IP FPM for packet loss and delay measurement, if two or more bits in the IPv4 packet header have not been planned for other purposes, they can be used for packet loss and delay measurement at the same time. If only one bit in the IPv4 packet header has not been planned, it can be used for either packet loss or delay measurement in one IP FPM instance.
  • Authentication mode (HMAC-SHA256), password (Huawei-123), key ID (1), and UDP port number (2048) on the UPE and NPE

  • Packet loss alarm threshold and its clear alarm threshold (respectively 10% and 5%); two-way delay alarm threshold and its clear alarm threshold (respectively 100 ms and 50 ms)

Procedure

  1. Configure interface IP addresses.

    Assign an IP address to each interface according to Table 2-1 and create a loopback interface on each node. For configuration details, see Configuration Files in this section.

  2. Configure OSPF.

    Configure OSPF on each node to allow the nodes to communicate at the network layer. For detailed configurations, see Configuration Files in this section.

  3. Configure basic MPLS functions and public network tunnels.

    • Configure basic MPLS functions and enable MPLS TE, RSVP-TE, and Constraint Shortest Path First (CSPF).
