摘要： A virtual computer system, including one or more virtual machines (VMs), is connected to a computer network by multiple network interface cards (NICs). The VMs are supported by a kernel, which includes a resource manager for allocating system resources among the VMs, including network data bandwidth. A NIC manager is loaded into the kernel as a driver or is integrated into the kernel, for selecting NICs over which outgoing network data is transferred, including providing functions such as failovers and failbacks, as well as load distribution. Implementing the NIC manager in the kernel provides NIC teaming functions to each of the VMs without having to implement a NIC teaming solution in each of the VMs, adding to the simplicity, flexibility and portability of the VMs. In addition, integrating the NIC manager into the kernel improves the kernel's ability to manage the VMs and to implement network resource allocations for the VMs.

摘要： A method for protecting a virtual computer system which may be susceptible to adverse effects from a Denial of Service attack is described. The virtual computer system includes a plurality of VMs. In the method, data that is transferred between the virtual computer system and the computer network is monitored for an indication of a possible Denial of Service attack. If an indication of a possible Denial of Service attack is detected, one or more of the VMs is suspended, to reduce the risk of adverse effects on one or more other VMs.

摘要： Methods, systems, and devices for wireless communications are described. An encoder of a wireless device may receive a transport block (TB) for transmission and segment the transport block into a set of multiple, smaller data segments that respectively In correspond to a plurality of code blocks of the TB. The encoder may generate a code block level (CB-level) error detection code (EDC) for a subset of the data segments. The encoder may generate a transport block-level (TB-level) EDC for the TB using the data segments. Each of the code blocks (CBs) may be of the same size and may include one of the data segments. A subset of the CBs may include a data segment from the subset of the data segments and one of the CB-level EDCs. The remaining CBs that are not part of the subset may include a remaining data segments and the TB-level EDC.

摘要： A transmitting device may identify a set of bit locations of a polar code for encoding an input vector based at least in part on a reliability order of the bit locations, where the input vector includes a set of payload bits. The transmitting device may map bits of the input vector to respective bit locations of the identified set of bit locations and may apply a masking operation to a subset of bits of the input vector that is mapped to a most reliable subset of the set of bit locations. The transmitting device may perform an encoding operation according to the mapped input vector to generate a codeword for transmission. A receiving device may perform complementary operations to obtain the payload bits of the input vector. Based on the described techniques, a false alarm rate for the receiving device may be suppressed.

摘要： Methods, systems, and devices for wireless communications are described. A transmitting device, such as a base station or a user equipment (UE), may generate a first set of encoded bits using a polar code. The transmitting device may transmit the first set of encoded bits to a receiving device, but the receiving device may unsuccessfully receive the transmission. The transmitting device may prepare a retransmission by generating a second set of encoded bits. In some cases, the transmitting device may copy information bits from the first transmission to polarized channels when generating the polar code for the retransmission. The transmitting device may copy information bits based on how the information bits were assigned for the first transmission as well as the block length. The transmitting device may copy information bits such that the retransmission is self-decodable.
