Using Service Session Profiles

662
Manager does not have to rebuild the service—it bases the new service on the service
that it built for the first service session. After you deactivate the first session, Service
Manager must build a new service for any subsequent subscribers.
Preprovisioning entails activating a service for a dummy user on the null interface. You
can then use the preprovisioned service session to activate service sessions for actual
subscribers. This technique improves performance because you only require Service
Manager to build the service one time, then reuse the original service when you activate
future subscriber service sessions.
To preprovision a service you use a command similar to the following example:
host1(config)#service-management subscriber-session dummy interface null
service-session "tiered(1000000, 2000000)"
Service session profiles provide additional flexibility to the Service Manager application
by enabling you to assign one or more supported attributes to a particular activation of
a service.
For example, you might assign the same video service to two subscribers, but use different
service session profiles to set different time limits for each subscriber's service. One
subscriber uses the video service for 5 hours (18000 seconds) while the other subscriber's
video service is for 10 hours (36000 seconds). Or, you might enable statistics on a
subscriber's voice service and disable statistics on the same subscriber's video service.
You can create multiple service session profiles independent of the service activation
process. Then, when you activate a service session, you specify the profile that you want
to use with that particular service session—you can apply one profile to a service session.
You can configure the following attributes in service session profiles:
statistics—Enables statistics and specifies the type of statistics you want to capture
for the service. See "Configuring Service Manager Statistics" on page 667 for additional
information about capturing Service Manager statistics. You can specify the following
types of statistics:
time—The service's duration
volume-time—The service's duration and traffic volume
volume—Specifies that the service is automatically deactivated when the indicated
traffic volume is exceeded.
time—Specifies that the service is automatically deactivated when the indicated time
period is exceeded.
NOTE: The volume and time attributes use values captured by the Service Manager
statistics feature to determine when the threshold is exceeded. Service Manager collects
time statistics by default—you must configure and enable volume statistics collection.
