Service Loss
Service Loss
Service Loss is an event which occurs when the Cisco SCE platform does not provide the processing it
was expected to perform for any transaction in the network. This can occur due to either CPU or Flows
shortage.
There are two different situations which can result with service loss in the Cisco SCE platform:
•
Temporary – This might occur when some network pattern which is short in its nature occurred and
caused the Cisco SCE platform to exhaust some of it resources temporarily. An example could be a
DDoS attack that the Cisco SCE platform could not detect and filter.
This is usually measured in seconds.
•
Permanent – In cases where the Cisco SCE platform is installed in locations where the network
traffic does not match its capacity and performance envelopes, permanent service loss can occur.
This is measured in hours.
Service loss is defined as the ratio of the number of packets that did not receive service as expected to
the total number of packets that were processed by the Cisco SCE platform.
Monitoring Service Loss
•
SNMP
cscTpServiceLoss
MIB available for each traffic processor.
Refer to the cisco-service-control-tp-stats MIB for more information.
It is expected that the Cisco SCE platform user will define timeslots in which this variable is monitored
(reset it between timeslots).
Note that the units for this variable are 0.001% and the information is rounded down.
