Abstract: Various methods and systems are provided for space, frequency and time domain coexistence of RF signals. In one example, among others, a communication device includes a coexistence manager capable of monitoring operating conditions of a cellular modem and a coexistence assistant capable of monitoring operating conditions of a wireless connectivity unit. The coexistence manager is capable of modifying operation of the modem and/or unit based on an operating condition change. In another example, a method includes detecting a change in antenna isolation and/or operating temperature of a FE filter, determining filtering characteristics of the FE filter based at least in part upon the change, and modifying communications of coexisting communication protocols based at least in part upon the filtering characteristics. In another example, a TX/RX configuration for coexisting communication protocols is determined and communications in a protocol is modified based at least in part upon the TX/RX configuration.

Abstract: A device includes circuitry configured to determine characteristics of jammer signals associated with a first wireless protocol of another device. An amount of interference between the jammer signals and a first received signal at the device associated with a second wireless protocol is determined, and the jammer signals are filtered from the second received signal when the amount of interference between the jammer signals and the first received signal is greater than a first predetermined threshold.

Abstract: A management controller in a network device may support performing management operations based on management traffic communicated wirelessly via a wireless network controller of the network devices. The management controller may perform the management operations and/or to support wireless communication of the management traffic independent of operations of the network device. The management controller may be integrated into a network controller in the network device. The management traffic may comprise out-of-band (OOB) management related traffic. A direct interface may be established between the management controller and the wireless network controller, to support direct sideband communication between the management controller and the wireless network controller. The sideband interface may incorporate Network Controller Sideband Interface (NC-SI) and/or Secure Digital Input Output (SDIO) interface.

Abstract: A method includes storing an address in an entry of a first memory device that is accessible by an address manager while the address is being stored in an entry of a second memory device included in a packet-forwarding device.

Abstract: An apparatus and a system, as well as a method and an article, may operate to control a data flow associated with one of a plurality of ports sharing a resource, including a memory. The port having the controlled data flow may have an actual usage value above a determined average shared resource usage value associated with the plurality of ports.

Abstract: An apparatus and a system, as well as a method and article, may operate to immediately terminate fetching a packet from memory after determining that transmission of the packet has been aborted.

Abstract: A method includes using dual free link lists and may be extendable to use more than two free link lists in managing a packet memory. The method includes providing a multi-port link memory. The link memory contains pointers to storage locations in the packet memory that is to be managed. The method provides for maintaining dual free link lists of free pointers in the link memory pointing to free locations in the packet memory. The free links when used appear as separate linked sets of pointers to storage locations in a packet memory which contains packet data.

Abstract: An apparatus and a system, as well as a method and article, may operate to send a packet from a first switch to a second switch by way of a stacked port, the packet identifying a congesting port included in the second switch as a source of congestion with respect to a congested port included in the first switch.

Abstract: A method and system for processing data packets are described. The method stores a data packet in a memory location and locks the data packet memory location when the data packet is an IP multicast packet. The method can also set a count equal to a number of transmission ports of the data packet, decrement the memory count after each transmission of the data packet and make the memory location unlockable when the status count is equal to a predetermined value.
