Abstract: In a wireless mesh network, e.g., a WiFi network, having a root node and one or more extenders, a rogue extender can be removed from the network by (i) updating the list of authorized extenders stored at the root node to exclude the rogue extender and then (ii) changing the network address of the root node. In that case, the existing extenders will automatically re-initiate their on-boarding processes in which the root node will (1) provide the authorized extenders on the list with its new network address in response to probe requests received from those extenders and (2) ignore probe requests received from the rogue extender, thereby terminating the on-boarding process without providing its new network address to the rogue extender. Depending on the implementation, a remote configuration server can provide the new network address to the root node or the root node can select its own new network address.

Abstract: Architectures for inter-converting bitstreams and symbol streams of PAM and/or QAM constellations of different sizes that are not base-2 integers. Some of such constellations may be Gray-coded, and the constellation mapping may be performed to achieve an equiprobable distribution of different constellation symbols. Some embodiments may be compatible with FEC schemes. In an example embodiment, a transmitter DSP may employ a conventional constellation mapper preceded by an electronic encoder programmed to exclude some constellation-symbol labels from the bitstream applied to the mapper. In different embodiments, the electronic encoder may employ a CCDM and/or a long-division operation to select some amplitudes of the constellation and to exclude others. At least some embodiments are beneficially capable of achieving a smaller gap to the Shannon limit than comparable conventional solutions.

Abstract: A network includes a first node having a processor that incorporates a U-turn indicator into a header of an Internet protocol (IP) packet for transmission along a first path towards a second node. The U-turn indicator indicates that the first node expects to receive the IP packet back from the second node. The first node also includes a transceiver that transmits the IP packet including the header having the U-turn indicator along the first path.

The processor (or another processor in another node) detects the U-turn indicator in a header of the IP packet. The processor forwards the IP packet along a path to a destination node that does not include the node that originally transmitted the IP packet or drops the IP packet depending on whether an alternate path is identified.

Abstract: A method and apparatus is proposed for accurately evaluating the performance of optical transmitters under test conditions (such as high bit-rate modulation formats) that compromise the operability of standard test equipment used for this purpose. The proposed apparatus and method are similar to the elements associated with existing testing standards based on an optical eye diagram, with an important distinction that allows for accurate measurements of the transmitter's performance to be made. In particular, the sampling point for collecting eye diagram data samples in the inventive arrangement is shifted by half a period with respect to the conventional mid-eye sampling point, eliminating the need to include representative reference equalizer in the test equipment and providing an evaluation not influenced by the test equipment, resulting in a more accurate measurement of transmitter-related distortions.
