摘要： A network node comprising:
a message handling module configured to control the sending of messages to one or more output ports of the network node based on a rule set stored at the network node, the rule set comprising one or more rules;
a communication module configured to receive at least one update to the rule set from a controller node, separate from the network node, for changing the rule set;
a supervisor module configured to verify that the changes to the rule set instructed by the update comply with at least a first set of rule-compliance-criteria and, if so, the network node is configured to modify the rule set to implement the changes of the update and, if not, the network node is configured not to implement the changes to the rule set.

摘要： An apparatus comprising:
a receive-input for coupling to a transmission medium;
a transceiver configured to receive signals representative of one or more data transmission units from the receive-input and output said data transmission units;
a protocol module configured to process at least a subset of the one or more data transmission units output from the transceiver according to a protocol, said processing including at least removing one or more fields of information from said subset of data transmission units associated with said protocol; and
wherein the apparatus is configured to add at least one field to the subset of data transmission units processed by said protocol module, the at least one field comprising protocol information derived from said processing by the protocol module and provide said data transmission units with the at least one field added to a receive-output of the apparatus.

摘要： 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).

摘要： 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.
