AVAIL vs. UNAVAIL: a test flow is considered to be in one of two stated either Available or Unavailable. A test

Seconds Ethernet). A SES
rate is exceeded, the test flow will remain in the Unavailable state until the commencement of a block of 10
consecutive non-SES
is defined as a second in which the FLR exceed a rate of 0.5 (50%). Once the SES
