EIR configuration test (color-aware)

This test verifies that a colored Ethernet service QoS profile has the expected behavior. It is assumed that the service has a QoS profile defined with CIR and EIR parameters as well as maximum frame loss ratio, delay, and jitter values for conforming frames. The test being color-aware means that one green and one yellow stream (two QoS classes) are present. In accordance with ITU-T Y.1564, the green stream is checked against CIR and the yellow stream against EIR. For both streams the following parameters need to be specified: frame size, source and destination UDP port, DSCP value, and VLAN priority (p-bits).

Test procedure

  • The sender Test Agent generates green frames at a rate equal to CIR, and yellow frames at a rate equal to EIR. The combined rate should not exceed the link rate.
  • The receiver Test Agent measures received rate, loss, delay, and jitter on both streams (green and yellow). The test fails if any of the thresholds for maximum loss ratio, delay, or jitter is exceeded for the green stream.

Reference

The test conforms to ITU-T Y.1564 section 8.1.2, test B.1.

Parameters

General

  • Sender: The sender interface.
  • Receiver: The receiver interface.
  • Test duration (s): Duration of the test in seconds. Min: 5 s. Max: 60 s. Default: 20 s.
  • Wait for ready: Time to wait before starting the test. The purpose of inserting a wait is to allow all Test Agents time to come online and acquire good time sync. Min: 1 min. Max: 24 hours. Default: "Don't wait", i.e. zero wait time.

QoS profile

  • CIR (Mbit/s): Committed information rate. Min: 0.1 Mbit/s. Max: 10000 Mbit/s. No default.
  • EIR (Mbit/s): Excess information rate. Min: 0.1 Mbit/s. Max: 10000 Mbit/s. No default.
  • Max frame loss (%): Maximum frame loss ratio for conforming packets. Min: 0%. Max: 100%. No default.
  • Max frame delay (ms): Maximum frame delay for conforming packets. Min: 0 ms. Max: 1000 ms. No default.
  • Max frame jitter (ms): Maximum frame jitter for conforming packets. Min: 0 ms. Max: 1000 ms. No default.

Traffic profile for CIR (green) stream

  • Frame size (bytes): Ethernet frame size in bytes. Min: 64 bytes. Max: 1518 bytes. Default: 512 bytes.
  • Source UDP port: The source UDP port to use. Range: 1 ... 65535. Default: 5000.
  • Destination UDP port: The destination UDP port to use. Range: 1 ... 65535. Default: 5000.
  • DSCP: The Diffserv code point. Range: 0 ... 63. Default: 0.
  • VLAN priority (PCP): Priority bits in VLAN header. Min: 0. Max: 7. Default: 0.

Traffic profile for EIR (yellow) stream

  • Frame size (bytes): Ethernet frame size in bytes. Min: 64 bytes. Max: 1518 bytes. Default: 512 bytes.
  • Source UDP port: The source UDP port to use. Range: 1 ... 65535. Default: 5001.
  • Destination UDP port: The destination UDP port to use. Range: 1 ... 65535. Default: 5001.
  • DSCP: The Diffserv code point. Range: 0 ... 63. Default: 0.
  • VLAN priority (PCP): Priority bits in VLAN header. Min: 0. Max: 7. Default: 0.
