摘要
Technologies for efficient network flow classification include a computing device that receives a network packet that includes a header. The computing device generates a vector Bloom filter (VBF) key as a function of the header and searches multiple VBFs for a VBF that matches the VBF key. Each VBF is associated with a flow sub-table that includes one or more flow rules. Each flow sub-table is associated with a mask length. If a matching VBF is found, the computing device searches the corresponding flow sub-table for a flow rule that matches a masked header of the network packet. If no matching VBF is found or if no matching flow rule is found, the computing device searches all of the flow sub-tables for a flow rule that matches the header. The computing device applies a flow action of a matching flow rule. Other embodiments are described and claimed.
