  • System and method for transferring data between a user space and a kernel space in a server associated with a distributed network environment
    Patent number: 8996612
    Abstract: A system (150) and method are disclosed that provide for the transfer of at least one packet (194) comprising data between a user space (152) and a kernel space (154) associated with a server (156) that is positioned in a distributed network arrangement (192) with a plurality of clients (158, 160, 162, 164). A distribution program (168) associated with the user space (152) is operable to accumulate the at least one packet (194). An application program interface (174) associated with the user space (152) transfers the at least one packet (194) to the kernel space (154) with a number of software interrupts (204). A driver (176) associated with the kernel space (154) is operable to distribute the at least one packet (194) to a subset of the plurality of clients (158, 160, 162, 164) in response to receiving the number of software interrupts (204). The number of software interrupts (204) is less than one software interrupt per packet per client.
