Abstract: A network management gateway device, method, and software is disclosed which communicates and translates between more sophisticated digital data network monitoring devices and managers, such as SNMP managers, and managed network devices, such as OpenFlow packet switches, which often are not sophisticated enough to respond to SNMP or REST type monitoring methods. This gateway may communicate with managed devices in one or more of a variety of modes. The manager may communicate with the gateway directly, or be configured to communicate with the managed device while the communications are redirected to the gateway and processed by the gateway. In some embodiments, the gateway may use the OpenFlow protocol to communicate management data with an OpenFlow switch and to install a flow in the switch to redirect management traffic to the gateway. Other routers and switches may also be used to redirect network management traffic to the gateway as well.

Abstract: Disclosed is a system for processing data streams that includes a parallel processor and a netflow aggregator module to generate a storage representation for data packets. Each storage representation includes segments of information about the data packet, the segments of information including information about a communication protocol specification related to the data packet.

The netflow aggregator module groups data packets by their composite index. The netflow aggregator module generates a session flow identifier by identifying a beginning and/or end of a transmission netflow for each data packet having the same data packet association characteristic. The netflow aggregator module aggregates and orders the data packets having the same session flow identifiers into a flow channel.
