Samsung patents switch method using FPGAs to speed up data packet processing

This patent describes a method for a switch server to handle data traffic using field programmable gate arrays (FPGAs). The system checks if incoming data packets match a pre-loaded list of rules; if they do, the FPGA processes them immediately, but if not, the packets are sent to a separate server for further handling.

Why it mattersThis improves network efficiency by offloading routine data processing tasks to specialized hardware, which can help manage high-speed data flows in communication systems.

In the filing’s own words

A method, in a communication system, carried out by a switch server comprising a programmable switch and one or more field programmable gate arrays (FPGAs) is provided. The method includes receiving information related to a flow table from an offloading server, receiving data packets, identifying a FPGA corresponding to the data packets, identifying whether the data packets match a flow entry of a flow table of the FPGA, in case that the data packets match the flow entry of the flow table, processing the data packets based on the flow entry and transmitting the processed data packet, and in case that the data packets do not match the entry of the flow table, providing the data packets to the offloading server.

What exactly they claim (claim 1)

1. A method performed by a switch server including a programmable switch and one or more field programmable gate arrays (FPGAs) in a communication system, the method comprising: receiving information on a flow table from an offloading server; receiving data packets; identifying an FPGA corresponding to the data packets; identifying whether the data packets match a flow entry of the flow table of the FPGA; if the data packets match the flow entry of the flow table, processing the data packets based on the flow entry and transmitting the processed data packets; and if the data packets do not match the flow entry of the flow table, providing the data packets to the offloading server.
