    Abstract: A network switch is disclosed. The network switch includes an input port and an output port. The network switch further includes a rule logic and a memory for storing a configurable counter. The rule logic is configured to inspect a packet received via the input port and attempt to find a rule for the packet and if the rule is found, to reset the counter and process the packet according to a preconfigured follow up action associated with the rule and if the rule is not found, to route the packet according to a default rule. The rule logic is configured to identify the packet for a follow up action based at least on a subset of content of the packet including a header and a payload of the packet. The counter may hold a time value or the number of packets from a same source to a same destination, a number of bytes received from the same source to a same destination, or a user configurable parameter to control the rule validity period.

    Abstract: An apparatus for providing an interface between a first network that operates based on a first protocol and a second network that operates based on a second protocol, includes a receive terminal configured to receive one or more first messages encoded according to the first protocol, the first messages encapsulating a plurality of second messages. The apparatus is configured to extract encapsulated second messages, determine for each of extracted second messages, and based on flow identifying information of each of extracted second messages, a flow to which the extracted second message belongs. The extracted second messages of the flow provide for transmission of the extracted second messages on the second network encoded based on the second protocol with a time spacing there between greater than a predetermined minimum time spacing.

    Abstract: A system configured to support software-defined networking, SDN, is described. The system comprises: a management client entity (310); main processing device (220, 320) operably connected to the management client entity (310) and arranged to communicate with the management client entity (310) using a first SDN protocol; a target server (330) running on a constrained device (228, 329) operably connected to the main processing device (220, 320) and arranged to communicate with the main processing device (320) using a second SDN protocol (242) that is different to the first SDN protocol. The main processing device (220, 320) comprises a data store (370) configured to perform as an interface between the first SDN protocol and the second SDN protocol (242).
