More Information
Summary:A raw policy set is received for the network processor and a dimension bitmap corresponding to the raw policy set. From the raw policy set, a policy tree builder generates a policy tree image from a set of recursive operations on the raw policy set including selecting boundaries of the raw policy set from cuts on a given dimension of the raw policy set, the dimension cut based on a dimension selection and a partition number selection for the raw policy set. Network processor hardware is configured according to the policy tree image including at least one set of registers, at least one set of tables, and at least one sequence of instructions. At runtime, the network processor applies the optimized policy set to processing of the packet session from the data communication network by the network processor hardware.
