摘要： A device may abstract access to hardware resources in the device to a single operating system (OS) running in the device utilizing an abstraction layer and a software partition. The abstraction layer and the software partition may enable virtualizing the hardware resources during interfacing between the single OS and the hardware resources, such that the actual characteristics and/or number of the hardware resources may be abstracted. The abstraction layer may comprise a hypervisor, which may be optimized to support network abstraction based operations. The software partition may enable managing configuration and/or use of the hardware resources via the abstraction layer. The hardware resources may comprise networking resources. Accordingly, operations of a plurality of virtual drivers within the OS corresponding to each of one or more of the plurality of hardware resources may be supported. Data transfers between the OS and the hardware resources may be performed via the software partition.

摘要： A system for reordering frames may include at least one processor that enable receiving of an out-of-order frame via a network subsystem. The at least one processor may enable placing data of the out-of-order frame in a host memory, and managing information relating to one or more holes resulting from the out-of-order frame in a receive window. The at least one processor may enable setting a programmable limit with respect to a number of holes allowed in the receive window. The out-of-order frame is received via a TCP offload engine (TOE) of the network subsystem or a TCP-enabled Ethernet controller (TEEC) of the network subsystem. The network subsystem may not store the out-of-order frame on an onboard memory, and may not store one or more missing frames relating to the out-of-order frame. The network subsystem may include a network interface card (NIC).

摘要： A method and system for handling or processing out-of-order TCP segments in a wireless system may comprise at least one of: placing a first TCP segment received by a wireless network processor in a host buffer and having a mapping between a TCP sequence number and a corresponding buffer address. It may be determined whether a second TCP segment received by the wireless network processor is one of an in-order TCP segment or an out-of-order TCP segment. If the second received TCP segment is an out-of-order TCP segment, then control information associated with at least the second TCP segment may be stored locally on the wireless network processor. The out-of-order TCP segment may be placed in a portion of the host buffer.
