  • Patent number: 9369925
    Abstract: Embodiments are provided for scheduling resources considering data rate-efficiency and fairness trade-off. A value of Jain's fairness index (JFI) is determined for transmitting a service to a plurality of users, and accordingly a sum of throughputs is maximized for transmitting the service to the users. Alternatively, a sum of throughputs is determined first and accordingly the JFI is maximized. Maximizing the sum of throughputs or JFI includes selecting a suitable value for a tuning parameter in an efficiency and fairness trade-off relation model. In accordance with the values of sum of throughputs and JFI, a plurality of resources are allocated for transmitting the service to the users. For static or quasi-static channels, the relation model is a convex function with a monotonic trade-off property. For ergodic time varying channels, the tuning parameter is selected by solving the relation model using a gradient-based approach.

  • Patent number: 9363583
    Abstract: System, apparatus, and method embodiments are provided for suppressing the stimulated Raman scattering (SRS) crosstalk in multiple wavelength channel signals propagating in fiber links, such as in WDM/DWDM or other optical communications systems. The SRS is reduced or suppressed by separating the channels into two sets of different channels, such as even and odd channels, and then performing subtraction of signal amplitudes between the two sets of channels. The channels are separated by an interleaver into the two sets. Alternatively, a wavelength selective switch (WSS) is used to separate the channels into the two sets on which the subtraction of signal amplitudes is then performed. In an embodiment, the signals are low frequency modulation signals used for channel monitoring for optical communications systems.

  • Patent number: 9361238
    Abstract: Methods and apparatuses for insertion, searching, deletion, and load balancing using a hierarchical series of hash tables are described herein. The techniques disclosed provide nearly collision free or deterministic hash functions using a bitmap as a pre-filter. The hash functions have different priorities and one hashing result will be used to perform main memory access. For the hash functions, two hash bitmaps are used to store valid data and collision information. There is no collision allowed in the hash tables except for the hash table with the lowest priority. The hash tables and bitmaps may be stored in one or more caches in (e.g., a cache of a CPU, Block RAMs in FPGAs, etc.) which perform much faster than main memory.
