FIELD: data processing.
SUBSTANCE: group of inventions relate to the field of data transmission. For this, proposed is the tabular search method for the OpenFlow table, in which the OpenFlow tables of different levels are divided into the flow tables with exact matching and at least one flow table with the classification matching; flows table configuration information is transferred to the flows tables with exact matching or the flows table with the classification matching and performing the search by exact matching flows tables using all of the packet keywords, at that, when the corresponding table entry is found, performing the packet processing according to the action specified in the table entry, and when the corresponding table entry is not found, extracting keywords from the packet various key fields to perform the parallel search in at least one flows table with the classification matching, dynamically creating flows table entry with exact matching and performing the packet processing according to the action specified in the table entry.
EFFECT: increase in the switching efficiency.
