Abstract: Methods and systems for load sharing signaling messages at the MTP level are disclosed. When a signaling message is received, it is determined whether the signaling message includes a routing indication indicating route-on-point-code-subsystem-number. If the routing indicator indicates route-on-point-code-subsystem-number, it is determined whether the signaling message belongs to an MTP level 3 load sharing group. If the signaling message belongs to an MTP level 3 load sharing group, the signaling message may be routed to any of the point codes in the MTP level 3 load sharing group. Routing the signaling message to a point code in the MTP level 3 load sharing group may include replacing the destination point code in the signaling message with the destination point code of the node to which the signaling message is to be routed. Once the point code has been replaced, the signaling message is routed to the destination associated with the point code.

Accordingly, the compressed packet data may be transferred over a communication network.

Abstract: An analysis of a communication configuration in a process control (PC) or substation automation (SA) system is disclosed, wherein network messages, and/or respective message sources, configured for transmission across a communication network of the system can be evaluated.

For each retrieved receiver IED, the totality of all network messages destined for or directed to this particular receiver IED can be evaluated or processed (e.g. in view of a subsequent network load analysis, virtual local area network assignment, or graphical display of the data flow).

Abstract: A wireless communication device including a first transceiver, a second transceiver, and a coexistence module. The first transceiver transmits a first signal and operates according to a first wireless communication standard. The second transceiver selects a first channel of multiple channels and transmits a second signal on the first channel. The second transceiver operates according to a second wireless communication standard. The first channel is associated with a frequency. The coexistence module, based on the frequency of the first channel, alters a transmission characteristic of the first signal to be transmitted by the first transceiver and alters a transmission characteristic of the second signal to be transmitted by the second transceiver. The transmission characteristic of the first signal and the transmission characteristic of the second signal, as altered by the coexistence module, prevent interference with the first signal and the second signal.

Abstract: A method and apparatus for processing timeout events in a packet network are disclosed. For example, the method detects a timeout event by a first network element, wherein the timeout event is generated due to a lack of response from a second network element. The method then determines whether a threshold for reporting of timeouts is exceeded for the second network element. The method then generates a report by the first network element to a fault management system if the threshold is exceeded, where the report indicates that the second network element has exceeded the threshold for reporting of timeouts.
