Abstract: Networks devices interconnected via link groups may implement micro operations administration and maintenance (micro-OAM) sessions. The micro-OAM sessions may be used to monitor the status of individual links within the link groups at small time scales. The micro-OAM session may be implemented on a non-internet protocol (non-IP) layer. In some cases, independent micro-OAM sessions may be used to monitor different links within a link group.

Abstract: An environment, such as an industrial environment, may include a control network with multiple network devices. A network device in the control network may have groups of communication ports servicing upstream and/or downstream network traffic. The group of communication ports may have, for example, two communication ports. Transmission parameters of the communication ports may be dynamically configured based on a first network port configuration and a second network port configuration for the first and second communication ports, respectively. The first network port configuration may have different transmission parameters than the second network port configuration. The first network port may forward data packets over the control network according to the first network port configuration, while the second network port may forward data packets to the next hop device utilizing the second network port configuration.

Abstract: A system forwards congestion management messages to a source host updating the source address in the management message. The system may determine that the congestion management message was triggered responsive to an initial communication that was previously forwarded by the system. The system may use header translation within a single addressing scheme and/or may translate the congestion management message into a different type to support forwarding to the source of the initial communication. The system may use portions of the payload of the congestion management message to determine the source of the initial communication and to derive a different header for the translated congestion management message.

Abstract: Aspects of geotagged communications are described herein. In one embodiment, a data unit including a geotag field is received over an ingress port of a network component. In turn, the network component may determine a path for forwarding the data unit to a location associated with the geotag field and with reference to a forwarding decision index. The path may include a least distance hop or a least distance route for forwarding or routing the data unit. With reference to the forwarding path, the network component may identify an egress port for forwarding the data unit. The network component may also forward the data unit over the egress port. According to other aspects, geolocation data may enable a network component to implement geotag-based virtual local area networks, geotag-based multiprotocol label switching, geotag-based fault detection and isolation, or geotag-based firewalls and fencing in wired routers or switches, for example.

Abstract: A system for providing oversubscription of pipeline bandwidth comprises a steer module, an absorption buffer, an ingress packet processor (IPP), a memory management unit (MMU), and a main packet buffer. The steer module receives packets that include start of packet (SOP), middle of packet (MOP), and end of packet (EOP) cells, attaches a packet identifier to the cells, passes the MOP and EOP cells to the MMU, and stores the SOP cells and EOP metadata in the absorption buffer. The IPP processes the SOP cells and EOP metadata and passes the same to the MMU. The MMU stores the MOP, EOP, and processed SOP cells in the main packet buffer, combines, upon receiving the processed EOP metadata of each packet, the processed SOP cell, the MOP cells and the EOP cell of each packet to reconstruct each packet, and queues each reconstructed packet in an egress port queue.

Abstract: A device with dynamically tunable heterogeneous latencies includes an input port configured to receive a packet via a network, and a processing module configured to determine multiple values corresponding to a number of qualifying parameters associated with the packet. The processing module may use the values to generate a selector value and may allocate a latency mode to the packet based on the selector value.
