BENEFITS OF ALCATEL-LUCENT DEVICES COMMON CLASSIFIERS
Following are the benefits of Alcatel-Lucent common classifiers:
• Usage of common classification by different features.
• Classification can be optimized and hence would lead to better performance of the
devices.
• Unified and consistent syntax, which allows users to manage their classification
configuration separately from the feature specific parameters and configuration.
• Extension or enhancements can be made to the classification configuration
without the need to make any changes to the feature configuration.
CC ARCHITECTURE
A key design aspect of the CC is that it separates the classification from the
action. This allows the classification to be performed once for a particular packet,
and then different features can use the result to derive their own action. The below
diagram depicts usage of common classification by different features.
Figure 3: Elements in Common Classifiers
Classifications, referred in applications are known by names assigned to them
when they are first defined. The classifications themselves are composed of a
number of elements and are designed to be nested or serialized. Ultimately,
classifications are composed of one or more rulesets, each of which consist of
one or more rules. Rules themselves can consist of individual elements arranged
in a specific manner, and can include references to lists of elements.
