  • Patent number: 11003385
    Abstract: According to one embodiment, a memory system stores write data received from a host to a shared write buffer for write destination blocks, acquires first write data for plural pages from the shared write buffer, and writes the first write data to a first write destination block by a first-step write operation. When receiving write data from the host in a state in which an empty region does not exist in the shared write buffer, the memory system discards write data in the shared write buffer in which the first-step write operation has been finished. In a case where the first write data do not exist in the shared write buffer when a second-step write operation of the first write data is to be executed, the memory system transmits a request to acquire the first write data to the host.

    Abstract: A system and method for a self-adapting SDWAN to ensure compliance with client requirements. A SDWAN performance analyzer continuously monitors all of the nodes within an SDWAN, receiving a plurality of operational data regarding operational parameters of each node. Based on the operational data, a machine learning algorithm is applied to develop a tree-structure representative of a desired network configuration, based on the real-time state of the network, to ensure compliance with client requirements. The SDWAN performance analyzer can generate configuration commands to send to one or more of the nodes in the SDWAN to reconfigure the operational parameters of the nodes in line with the desired network configuration.

  • Patent number: 10862617
    Abstract: Systems and methods of using a packet order work (POW) scheduler to assign packets to a set of scheduler queues for supplying packets to parallel processing units. A processing unit and the associated scheduler queue is dedicated to a specific flow until a queue-reallocation event, which may correspond to the associated scheduler queue being idle for at least a certain interval as indicated by its age counter, or the queue being the LRU, when a new flow arrives. In this case, the scheduler queue and the associated processing unit may be reallocated to the new flow and disassociated with the previous flow. As a result, dynamic packet workload balancing can be advantageously achieved across the multiple processing paths.
