Service-Level Agreement Measurement

Service-level agreement (SLA) measurement is the process of monitoring the bandwidth, delay, delay variation (jitter), continuity, and availability of a service (E-Line or E-LAN). It enables you to identify network problems before customers are impacted by network defects.

The Ethernet VPN services can be classified into:

  • Peer-to-peer-services (E-Line services)—The E-Line services are offered using MPLS-based Layer 2 VPN virtual private wire service (VPWS).
  • Multipoint-to-multipoint services (E-LAN services)—The E-LAN services are offered using MPLS-based virtual private LAN service (VPLS).

Note: For more information, see the Junos VPNs Configuration Guide.

In Junos OS, SLA measurements are classified into:

  • On-demand mode—In on-demand mode, the measurements are triggered through the CLI. For more information, see On-Demand Mode.
  • Proactive mode—In proactive mode, the measurements are triggered by an iterator application. For more information, see Proactive Mode.

For more information about frame delay measurement, see Ethernet Frame Delay Measurements Overview. For more information about frame loss measurement, see Ethernet Frame Loss Measurement Overview. Note that Ethernet frame delay measurement and Ethernet frame loss measurement are not supported on the ae interface.
