He holds 3 patents that focus on innovative methods for classifying network packets. His work has significantly impacted how data is processed and managed in networking environments.

Latest Patents

Hugh Nhan's latest patents include a method for classifying packets using multi-class structures. In one embodiment, a super class that contains a plurality of matching rules is generated. The matching rules of the super class are converted into a hierarchical arrangement of lookup tables and equivalence sets, the hierarchical arrangement having a plurality of levels including a first level and a final level. A final equivalence set is associated with the final level. The lookup tables and final equivalence set are then used to generate a results table that indicates a network packet is associated with a particular class. Another patent describes a technique for classifying a packet in a deterministic number of lookup operations. This technique builds a single 'super class' that contains the match criteria for all the rules associated with packet classification. The 'super class' is then compiled to produce a series of lookup tables and equivalence sets, including a final lookup table and equivalence set. The final equivalence set is then “post-processed” to associate the entries in the final lookup table with a particular result.
