Latest Patents

One of his latest patents is titled "On-chip packet cut-through." This invention includes a method for avoiding memory bandwidth utilization during packet processing. The packet processing core receives a plurality of packets and identifies each packet's quality of service (QoS) descriptor. It determines that at least one packet should be moved to an off-chip packet store prior to being transmitted to the egress port, based on the packet's QoS descriptor. Additionally, the packet processing core decides that at least one packet should not be moved to the off-chip packet store before transmission, also considering the QoS descriptor.

Another significant patent is "Method and apparatus for packet classification." This invention reduces the amount of low-latency memory needed for rules-based packet classification by representing a packet classification rules database in compressed form. The packet processing rules database is preprocessed to obtain corresponding rule fingerprints, which are much smaller than the original rules. This allows for efficient accommodation in on-chip or low-latency memory. The rules database can be stored in off-chip or higher-latency memory, minimizing accesses to the rules database and enhancing overall performance.
