Abstract
Mechanisms are provided for configuring a data flow between a source device and a destination device in a network. The mechanisms receive, from a network control application, a request to establish a network configuration corresponding to a data flow between the source device and the destination device. The request comprises a fine grained header field tuple for defining the data flow. The mechanisms allocate, from a shadow address pool, a shadow address to be mapped to the fine grained header field tuple. The shadow address pool comprises addresses not being used by devices coupled to the network. The mechanisms configure a network infrastructure of the network to route data packets of the data flow from the source device to the destination device based on the shadow address.
