Categories
In certain installations, data must be sent to different collector servers according to their type. For
instance, in the pre-paid environment, some types of data must be sent to the pre-paid collector to get a
new quota, while others should be sent to the mediation system. In this case, the data types are divided
into up to four groups, and each group, or category, is assigned to a particular destination or destinations.
The categories are defined by the application running on the Cisco SCE platform.
The system supports up to four categories:
•
Category 1—
Usage RDRs to the Collection Manager or mediation system
•
Category 2—
Quota RDRs to Pre-Paid Server or Subscriber Controller OSS
•
Category 3—
External events RDR or RT Signaling to various systems, such as a packet cable
multi-media policy server
•
Category 4—
URL Query RDR to URL Filtering database (for example, surfControl)
Each destination must be configured regarding each category in use. Each destination may be assigned
to more than one category and may be assigned the same or different priorities for each category.
It is also possible to remove a category from a destination, leaving only the desired category. If all
categories are removed, the destination itself is deleted.
By default, the categories are referred to as Category 1 through Category 4. However, you can define
meaningful names for the categories. This generally reduces confusion and prevents errors.
You can also configure the buffer size for each category. The total buffer size is 80 MB.
Priority
The priority value is used to indicate whether the destination should be a destination for a given category.
Priority is related to the redundant forwarding mode, in that it indicates which is the primary active
connection. Priority values have no effect in multicast forwarding mode.
Each destination is assigned a priority value for each category. The first destination that is configured is
automatically assigned a priority of 100 (highest priority) for all categories, unless explicitly defined
otherwise.
Following are some important points to keep in mind regarding priority values:
•
Two destinations may not have the same priority for one category. The priority values for
destinations within a category must be unique to have any meaning.
•
If only one priority value is assigned to the destination, that priority is automatically assigned to all
categories for that destination.
•
If only one category is assigned a priority value for a destination, no RDRs from the other categories
will be sent to the specified destination.
•
Assign a high priority if data from the specified category should be sent to this destination. Assign
a low priority if data from the specified category should less likely to be sent to this destination.
•
Redundant forwarding mode—Assign a high priority to the primary destination for the
system/category. Assign a lower priority to the secondary destination for the system/category.
