Abstract: Systems and techniques for forward error correction decode processing power reduction are described herein. A capacity of a network slice is determined for a user network interface (UNI) based on a subset of forward error correction (FEC) codewords to be decoded by the media access control processor. A number of decoder cores is calculated to decode the capacity of the network slice. A utilization value is determined for a decoder core. A decoder utilization value is calculated for the decoder cores using the utilization value a number of decoding iterations. A non-decoding media access control processor utilization value is obtained for the network slice. A geometry is calculated for the media access control processor using the number of decoder cores, the decoder utilization value, and the non-decoding media access control processor utilization value. A media access control processor manufacturing specification data is generated based on the calculated geometry.

Abstract: Systems and techniques for forward error correction decode processing power reduction are described herein. A first codeword is identified in a network transmission. A conditional decoding window is generated that begins with the first codeword. The conditional decoding window is aligned with a frame of the network transmission. A report is generated that includes an indication of relevance of the conditional decoding window to a network device. The conditional decoding window and the report are transmitted to the network device. A conditional decoding window is received that includes a first codeword. The first codeword is decoded to determine a second codeword. A report is obtained that includes a codeword relevance bit for the second codeword. Upon a determination that the codeword relevance bit indicates that the second codeword is irrelevant, the second codeword is discarded without decoding the second codeword.

Abstract: Embodiments include an automatic set top box placement (STB) process and system that balances video playback needs against the performance characteristics of individual devices and the communications system. For video playback, this involves maintaining required sustained data rates needed to support video of various levels of quality and resolution and matching these against the capacity of the Wi-Fi system in terms of channel capacity and gateway/Access Point to STB connection quality. An intelligent network controller calculates the STB total airtime. Each STB is associated with a Service Set Identifier (SSID) that the controller uses to identify the STB clients. The controller calculates the End-to-End PHY rates for each client. The total STB airtime can then be calculated and compared to the default allocation for the STBs. Recommendations regarding moving STBs, gateways, and or satellite/booster devices can then be provided to the user.

Based on the returned grant/block status, the services gateway may respond to the requesting device with the DNS resolution or access denial.

Abstract: Techniques are described for configuring an optical network unit (ONU) in a pre-burst state prior to transitioning the ONU to a burst-on state. During the pre-burst state, a laser emitter of the ONU stabilizes to its wavelength, thereby reducing the impact of wavelength drift when the ONU transitions to the burst-on state.

To improve reliability as well as manufacturing yield, a photonic integrated circuit (“PIC”) for as a multi-channel optical line terminal (“OLT”) contains spare lasers or standby lasers configured to replace a failed laser(s). In one aspect, PIC includes a set of fixed-wavelength lasers (“FWLs”), a tunable-wavelength auxiliary laser (“TWAL”), a photonic detector, and a tuner. FWLs, for example, generate optical wavelengths representing optical signals. TWAL generates an optical signal with a spectrum of wavelengths based on a setting generated by the tuner.
