摘要

Methods and systems for managing authorized data flows using software defined networking include receiving flow criteria sent from a firewall and extracted from a first data packet, determining whether flow criteria of the first data packet matches an entry in a master data flow list, inserting the flow criteria from the first data packet into the master data flow list on a software defined networking controller, and sending the flow criteria of the first data packet to the router. The router may forward a second data packet associated with the data flow toward a destination based on the validation of the first data packet by the firewall. The flow criteria may not match an entry in a router data flow list on the router and may include at least two of: a source IP address, a destination IP address, a destination port, and a protocol of transmission.

說明書

In operation, network 100 may be controlled using software defined networking (SDN) controllers, as described previously. Specifically, devices in network 100 may be configured and programmed in network 100 using various network protocols by SDN controllers. The SDN controllers may support managing authenticated data flows, as disclosed herein.

Referring now to FIG. 2, a block diagram of selected elements of a network for managing authorized data flows across domains is shown in accordance with some embodiments of the present disclosure. An embodiment of a network 200 for managing authorized data flows across domains in networks, such as, for example, in transport network 100 (see FIG. 1), is illustrated.
