  • Patent number: 11212220
    Abstract: A method performed by a switch in a software-defined network (SDN), the switch being communicatively coupled to a controller, is provided. The method includes performing a first flow action with respect to a first flow (e.g., deleting the first flow). The method further includes storing a first flow event data object, the first flow event data object indicating the first flow and the first flow action. The method further includes storing a first tag in association with the flow event data object. The method further includes generating a flow event message comprising the first flow event data object and the first tag. The method further includes sending the flow event message to the controller.
    Type: Grant

  • Patent number: 10050840
    Abstract: Methods of Internet of Things (IoT) device access are disclosed. In one embodiment, a method is implemented in a software-defined networking (SDN) controller. The method includes receiving a node discovery request from a network device that receives a unicast neighbor solicitation message from an electronic device that supports IPv6. The unicast neighbor solicitation message contains an IPv6 address to be registered. The method also includes causing a device entry to be generated in a device discovery table, and transmitting an acknowledgment to the network device upon the device entry being generated successfully. The method continues with transmitting a request to the network device to generate a flow table entry for the electronic device based on a policy table. The flow table entry includes an operation to be performed, and the network device is to perform the operation on a packet received matching the flow table entry.

  • Publication number: 20150363423
    Abstract: Methods and systems are described for redundant storage of a data block from a data source into a distributed file system over a software-defined network. According to one embodiment, the methods and system describe a cloud manager in the network that identifies a first and second storage server in a network, along with the clusters that the servers are in, and the in-cluster network elements (NEs) of those clusters. The cloud manager calculates best paths through the NEs of the network to reach the identified storage servers, reserves bandwidth along the best paths so that the data block can be sent, configures the forwarding tables of the NEs in these best paths to forward the data block to the storage servers, and sends the data block through the best paths.
