Abstract: Constraining resource provisioning by domain controllers based on resource requirements projected for remotely-originating inter-domain traffic can improve utilization efficiency and link reliability in multi-domain software defined network (SDN) architectures. A domain controller may be required to reserve a portion of inter-domain link capacity for transporting remotely-originating traffic. This may limit the inter-domain link capacity available for transporting locally-originating traffic in a manner that ensures remotely-originating traffic flows have equitable and/or adequate access to resources of inter-domain links. Alternatively, a domain controller may be required to maintain a minimum throughput rate for remotely-originating traffic, which may cause remotely-originating traffic to be prioritized over locally-originating traffic when necessary to maintain the minimum throughput rate. Provisioning constraints can be generated in a centralized or distributed fashion.

Abstract: Embodiments are provided for early termination of an iterative process of determining channel directions and transmissions in multi-user multiple-input and multiple-output (MU-MIMO) communications systems. In an embodiment, a base station or a user equipment (UE) calculates a multi-user channel matrix using a first iteration of a null-space singular value decomposition (SVD) based iterative zero-forcing (I-ZF) algorithm for multi-user MU-MIMO. The base station or UE repeats updating the multi-user channel matrix using a next iteration of the algorithm and the multi-user channel matrix calculated in a previous iteration, until the diagonal elements of the multi-user channel matrix are greater than the off-diagonal elements by a predefined threshold. Upon determining that the diagonal elements are greater than the off-diagonal elements by the predefined threshold, a plurality of transmission signals are calculated using the last updated multi-user channel matrix.

Abstract: Embodiments are provided for applying pilot tone modulations to optical signals by introducing bias bits to data frames carried on the optical signals. Since the modulation is done by modifying data, the modulation depth is accurate, and there is no need for calibration or feedback control, which can improve power monitoring accuracy and simplify implementation. In an embodiment, a transmitter determines a period of a pilot tone modulation for tracking or identifying an optical channel. The transmitter inserts a sequence of bias bits, periodically according to the determined period, in a plurality of frames comprising original data bits. The amplitudes of the optical signals carrying the frames are modulated at a higher frequency than the pilot tone modulation. The optical signals are then transmitted including the bias bits within the frames.
