Abstract: In general, a capability for forwarding packets based on path encoding is presented. The capability for forwarding a packet based on path encoding may be configured to enable forwarding of a packet along a network path by determining a path encoding label for the network path, associating the path encoding label for the network path with the packet, and forwarding the packet along the network path based on the path encoding label associated with the packet. The network path for a packet may include an ordered sequence of node output interfaces of an ordered sequence of nodes. The path encoding label for the network path includes an ordered sequence of node interface labels corresponding to the ordered sequence of node output interfaces of the nodes of the network path. The nodes of the network path forward the packet along the network path based on the path encoding label.

Abstract: A method and apparatus for latency control in an optical network. A management node such as an OLT in a PON sends a discovery message intending to prompt joining network nodes such as ONUs to send a response on a first wavelength during a quiet window established for this purpose. When a response is received, a secondary upstream-transmission wavelength is assigned to the ONU. When the ONU sends data upstream according to a schedule calculated by the ONT, which schedule may include transmission times using the assigned secondary wavelength. In this case, the assigned secondary wavelength will be scheduled using a relatively smaller or no quiet window. This scheduling may be determined in part by the service or services used by the ONU.

Abstract: A capability for localization of a wireless tag based on wireless gateway association information uses a wireless tag supporting multiple states and wireless gateway association information associated with the wireless tag to control localization of the wireless tag. The wireless tag may support an unconnected state in which the wireless tag communicates location tracking information using a wireless beacon signal which may be detected by various wireless gateways and a connected state in which the wireless tag communicates location tracking information via one or more connections with one or more wireless gateways. The wireless gateway association information may include wireless gateway lists (e.g., whitelists, blacklists, or the like), association rules, notification rules, or the like. The wireless gateway association information may be used to control transitions of the wireless tag between the unconnected state and the connected state, to control notifications for the wireless tag, or the like.

Abstract: A central node of a MIMO system may transmit, to one or more communication terminals of the MIMO system, a long-duration downlink pilot signal carrying a pilot sequence having a first duration. The first duration may be equal to or greater than a quantity of antennas of the central node. The central node may receive retransmitted long-duration downlink pilot signals from the communication terminals. The central node may further transmit, to one or more communication terminals, a short-duration downlink pilot signal carrying a pilot sequence having a second duration. The second duration may be less than or equal to the quantity of antennas. The central node may receive a retransmitted short-duration downlink pilot signal from the one or more communication terminals. An uplink and downlink between the central node and one or more communication terminals may be estimated based on the received signals.

Abstract: We disclose various embodiments that enable a mobile terminal to authenticate a base station before the mobile terminal proceeds to attach to the corresponding network and/or camp on the corresponding cell, e.g., during the initial network selection and attachment or during an idle mode. In an example embodiment, the authentication processing includes the mobile terminal generating and sending to a candidate base station a system query with a nonce. The candidate base station is deemed to be authentic only if the acknowledgement generated and transmitted in response to the system query includes a copy of the nonce properly signed by a digital signature generated using one or more security keys. In some embodiments, the system query may also include a request for GPS coordinates and/or selected system information signed using a digital signature, which the mobile terminal may beneficially use to further strengthen the protection against a spoofing attack.

Abstract: We disclose various embodiments that enable a mobile terminal to confirm authenticity of a base station before the mobile terminal proceeds to camp on the corresponding cell, e.g., during an idle mode. In an example embodiment, the authentication processing includes the mobile terminal validating a digital signature included in an information block received from a candidate base station, the digital signature having been generated by the base station using an extended time stamp that indicates the calendar year, month, and/or day in addition to the UTC time-counter value. The information block typically includes a truncated time stamp, which the mobile terminal uses to reconstruct the extended time stamp, the reconstruction being performed using a system time stamp that was previously broadcast by the base station. The reconstructed time stamp is then fed, together with other relevant data, into a security algorithm that can confirm the validity of the digital signature.

Abstract: We disclose various embodiments that enable a mobile terminal to confirm authenticity of a base station before the mobile terminal proceeds to camp on the corresponding cell. In an example embodiment, the authentication processing includes the mobile terminal tuning to a selected control channel of the base station to monitor RF signals transmitted thereon. The base station is deemed to be authentic if the monitored RF signals indicate the presence of live traffic between the base station and one or more other mobile terminals. The control channel can be selected from a fixed set of uplink and/or downlink control channels that are typically used by a legitimate base station. The presence of live traffic on the selected control channel can be detected by detecting certain control messages that are typically transmitted on that control channel between the base station and one or more mobile terminals served by that base station.

Abstract: We disclose embodiments of a WDM transmitter having an in-band OTDR capability for at least a subset of the WDM channels thereof. In an example embodiment, an OTDR-enabled WDM channel of the WDM transmitter is implemented using an optical transceiver that comprises an optical transmitter and a coherent optical receiver. The optical transmitter is configured to generate a modulated optical signal by modulating a respective carrier wavelength, transmit the modulated optical signal through an optical link as a component of the corresponding WDM signal, and provide the respective carrier wavelength to the coherent optical receiver for being used therein as an optical local oscillator. The optical receiver is configured to estimate an impulse response of the optical link by coherently detecting and processing a return optical signal produced within the optical link due to distributed reflection and/or backscattering of the modulated optical signal.

Abstract: We disclose a multichannel optical transceiver having a first optical channel used for client-data transmission over an optical fiber and a second optical channel that enables secure transport of encryption keys over the same optical fiber. In an example embodiment, the first channel uses a first carrier wavelength at which the optical fiber supports a single guided mode. The second channel uses a second carrier wavelength at which the optical fiber supports multiple guided modes. The secure transport of encryption keys can be achieved, e.g., by scrambling the encryption-key data over multiple space-division-multiplexed optical signals transmitted by way of the multiple guided modes. The securely transported encryption keys can then be used to enable the client data transmitted using the first optical channel to be encrypted to frustrate or prevent eavesdropping along the fiber length.
