Abstract: Technology related to managing network traffic flows is disclosed. In one example, a method can include searching a first data structure to determine whether a first entry associated with a network flow is present in the first data structure. In response to determining the first entry is present in the first data structure, at least a portion of the first entry can be used to generate an index for a flow cache. An action can be performed on the network packet as indicated by a flow cache entry, where the flow cache entry is located in the flow cache at the generated index.
