4.6.2 Profiles
Performance parameters, that is, the Latency and Jitter Buckets described above, can be
configured for each NID in the network. These metrics, along with other packet parameters, such
as priority, size, and number of packets per second, are used to define a profile. The profile
mimics the Subscriber's exchange of service frames between NIDs for the purpose of ensuring
that the overall quality of a CoS instance has been met and that the virtual circuit performance
attributes are within the values specified by the SLA.
Profiles are used to define both test parameters and control information. These let you define
differentiated types of service across a network. Such services let you classify and prioritize
packets based on the applications they support. Applications include packet voice, video, high
priority data, etc. When deleting a profile, the profile is marked for deletion and will not be purged
by the NID until all Test Result records that reference the deleted profile have been removed from
the system. Test results are removed from the NID by:
• Purging - records are removed after they have been stored over the time limit. The sys-
tem resets as these records are stored in volatile RAM.
• Telnet to the appropriate NID: 9145E.
