摘要： A packet is received at an ingress port of a networking device and a forwarding result that identifies an egress port for the packet is generated. In parallel with the generation of the forwarding result, a network address translation (NAT) result that identifies one or more NAT rules for possible application to the packet is generated. The forwarding result and the NAT result are then used to generate a routing decision result.

摘要： A shared network interface controller (NIC) interfaces a plurality of operating system domains as part of the load-store architecture of the operating system domains. A bus interface couples the NIC to a load-store domain bus (such as PCI-Express), using header information to associate data on the bus with an originating operating system domain. Transmit/receive logic connects the NIC to the network. Association logic allows the NIC to designate, and later lookup which destination MAC address (on the Ethernet side) is associated with which operating system domain. Descriptor register files and Control Status Registers (CSR's) specific to an operating system domain are duplicated and made available for each domain. Several direct memory access (DMA) engines are provided to improve throughput. Packet replication logic, filters (perfect and hash) and VLAN tables are used for looping back packets originating from one operating system domain to another and other operations.
摘要翻译：共享网络接口控制器（NIC）将多个操作系统域接口作为操作系统域的加载存储体系结构的一部分。总线接口将NIC耦合到加载存储域总线（例如PCI-Express），使用头信息将总线上的数据与始发操作系统域相关联。发送/接收逻辑将NIC连接到网络。关联逻辑允许NIC指定，并且稍后查找哪个目标MAC地址（在以太网端）与哪个操作系统域相关联。特定于操作系统域的描述符寄存器文件和控制状态寄存器（CSR）被复制并提供给每个域。提供了几个直接内存访问（DMA）引擎来提高吞吐量。数据包复制逻辑，过滤器（完美和散列）和VLAN表用于将源自一个操作系统域的数据包循环到另一个操作系统。

摘要： In a method of generating an orthogonal frequency division multiplexing (OFDM) symbol, a plurality of information bits is encoded to generate a plurality of coded bits. The plurality of information bits corresponds to a first bandwidth, while the OFDM symbol includes a number of data tones corresponding to a second bandwidth. The coded bits are mapped to a plurality constellation symbols. The constellation symbols are mapped to a first plurality of data subcarriers corresponding to a first portion of the OFDM symbol and to a second plurality of data subcarriers corresponding to a second portion of the OFDM symbol. A subset of data subcarriers in the first plurality of data subcarriers and in the second plurality of data subcarriers are set to one or more predetermined values. The OFDM symbol is then generated to include at least the first plurality of data subcarriers and the second plurality of data subcarriers.

摘要： Systems, methods and computer program products facilitate communication on a network by transmitting a communication on the network from a first node to a second node, the communication including a first segment and a second segment. The first segment consists essentially of a destination port and a data length of the communication, and the second segment includes a payload and at least one of a connection ID, a sequence number, and an opcode. A responsive communication is then received from the second node, the responsive communication acknowledging receipt of the communication transmitted from the first node.

摘要： A system and machine-implemented method for processing data associated with an application running on an electronic device. A server receives an HTTP header from the electronic device. The HTTP header is associated with an application running on the electronic device and specifies a content mode for the application. The content mode identifies a type of server content for a user of the application, and corresponds to at least one of plural modes including a child mode in which the type of server content is for a child user. The server receives a request for content from the electronic device, the request being associated with the application, and accesses content for the application based on the received request. The accessed content is provided for the application running on the electronic device. At least one of the accessing or the providing is based on the identified type of server content.

摘要： A packet processor for processing an input packet includes an information generator for generating process control information for processing the input packet, an internal packet generator for receiving the input packet as an packet to be processed and adding the process control information to the packet to be processed to produce an internal packet, an internal packet processor for processing the internal packet supplied from the internal packet generator on the basis of the process control information added to the internal packet, and a packet transmitter for extracting an output packet from the internal packet processed by the internal packet processor to transmit the output packet. The packet processor can reduce the amount of communication between modules even when the packet processor includes plural modules.

摘要： Certain aspects of the present disclosure provide techniques and apparatus for using different MAC addresses in frames for the same station to indicate how to process the frames. In this manner, frames for IEEE 802.11ac can carry information not present in legacy frames (e.g., frames according to IEEE 802.11a/n), but these frames may be interpreted by legacy devices in a legacy way. One example method generally includes receiving a first frame comprising an indication of a first MAC address and processing the received first frame based on the first MAC address. For certain aspects, the method further includes receiving a second frame comprising an indication of a second MAC address, wherein the second MAC address is different than the first address; and processing the received second frame based on the second MAC address, such that the processing of the second frame is different than the processing of the first frame.
摘要翻译：本公开的某些方面提供了用于在相同站的帧中使用不同MAC地址来指示如何处理帧的技术和装置。以这种方式，用于IEEE 802.11ac的帧可以携带在传统帧（例如，根据IEEE 802.11a / n的帧）中不存在的信息，但是这些帧可以由传统设备以传统方式解释。一个示例性方法通常包括接收包括第一MAC地址的指示并基于第一MAC地址处理接收的第一帧的第一帧。对于某些方面，所述方法还包括接收包括第二MAC地址的指示的第二帧，其中所述第二MAC地址不同于所述第一地址; 以及基于所述第二MAC地址处理所接收的第二帧，使得所述第二帧的处理与所述第一帧的处理不同。
