20150326425 | RECORDING, ANALYZING, AND RESTORING NETWORK STATES IN SOFTWARE-DEFINED NETWORKS - A system that includes a recorder that records information of a flow table of at least one network device in a network by capturing information regarding the flow table that is transmitted to and from the network device, wherein the network device receives and forwards incoming packet data over the network, and the flow table is used to determine how each incoming packet is handled by the network device; an analyzer that analyzes state changes in the network and manages a network state; and a restorer that, when a type of failure occurs in the network, recovers the network state by restoring at least a portion of the flow table using the recorded information of the flow table and based on the type of failure event that has occurred. | 11-12-2015 |
20150295852 | PROTECTING AND TRACKING NETWORK STATE UPDATES IN SOFTWARE-DEFINED NETWORKS FROM SIDE-CHANNEL ACCESS - A system and method of access control and tracking capabilities of programmable switches are described. A system and associated method include an access controller component and a tracker component. The access controller component defines access control rights for a user in a flow of a programmable switch in a network. The access control rights are determined by access control table information and an associated bit-array based flow-level role data structure built by a controller network operator. The tracker component authorizes and permits the user to modify the flow according to a flow modification request, which is based upon information in the access control table information and the associated bit-array based flow-level role data structure for the user. A notification component of a programmable switch notifies the controller of the network about the modification request to the flow. | 10-15-2015 |
