  • Patent number: 9571402
    Abstract: Systems and methods described herein are directed to solutions for NoC interconnects that provide congestion avoidance and end-to-end uniform and weighted-fair allocation of resource bandwidths among various contenders in a mesh or torus interconnect. The example implementations are fully distributed and involve using explicit congestion notification messages or local congestion identification for congestion detection. Based on the congestion level detected, the injection rates of traffic at various agents are regulated that avoids congestion and also provides end-to-end QoS. Alternative example implementations may also utilize end-to-end credit based flow control between communicating agents for resource and bandwidth allocation of the destination between the contending sources. The resource allocation is performed so that both the weighted and strict bandwidth allocation QoS policies are satisfied.

  • Patent number: 9538489
    Abstract: A wireless communication system to synchronize data transfer rates. A hard disk drive controller receives a first Long Term Evolution (LTE) Radio Resource Connection message generated by an eNodeB proposing a wireless communication network download data rate. The hard disk drive controller compares the proposed wireless communication network download rate in the first LTE RRC message with a hard disk drive storage data rate. If the proposed wireless communication network download rate is higher than the hard disk drive storage data rate, then the hard disk controller transfers a second LTE RRC message requesting a lower wireless communication network download rate.
