摘要： A method of filtering data packets in a network device is disclosed. An incoming packet is received from a port and the incoming packet is inspected and packet fields are extracted. The incoming packet is classified based on the extracted packet fields and action instructions are generated. The incoming packet is then modified based on the action instructions. Further, the inspection and extraction includes applying inspection mask windows to any portion of the incoming packet to extract programmable packet fields.

摘要： A network device is provided which includes a device input, at least one port, a frequency doubler, a data I/O device, and a programmable delay locked loop. The frequency doubler is coupled to the input and configured to receive an input signal and output an output signal having double the frequency of the input signal. The data I/O device is configured to output data based upon a reference clock signal. The programmable delay locked loop is coupled to the device input and configured to receive an input signal and to automatically output an output signal being a predetermined amount out of phase from the input signal. An external clock signal received at the device input is input to the frequency doubler. The output of the frequency doubler is input to the data I/O device as a reference clock. Data (e.g., from internal device logic) is output from the data I/O device to the at least one port. The external clock signal is input to the programmable delay locked loop, which outputs an output clock signal having a frequency equal to the frequency of the external clock signal, in synchronization with the data being output.

摘要： A network switch, configured for performing layer 2 and layer 3 switching in an Ethernet (IEEE 802.3) network without blocking of incoming data packets, includes a network switch port having a filter (i.e., a packet classifier module) configured for evaluating an incoming data packet on an instantaneous basis. The filter performs simultaneous comparisons between the incoming data stream of the data packet and multiple templates configured for identifying respective data protocols. Each template is composed of a plurality of min terms, wherein each min term specifies a prescribed comparison operation within a selected data byte of the incoming data packet. The templates may be programmed by a user and stored in an internal min term memory. Moreover, the multiple simultaneous comparisons enable the network switch to perform layer 3 switching for 100 Mbps and gigabit networks without blocking in the network switch.

摘要： Rapid channel failure detection and recovery in wireless communication networks is needed in order to meet, among other things, carrier class Ethernet channel standards. Thus, resilient wireless packet communications is provided using a physical layer link aggregation protocol with a hardware-assisted rapid channel failure detection algorithm and load balancing, preferably in combination. This functionality may be implemented in a Gigabit Ethernet data access card with an engine configured accordingly. In networks with various topologies, these features may be provided in combination with their existing protocols.

摘要： Embodiments of the present invention disclose a method for sending a code block data stream, including: adding m first data frames carrying the code block data stream to n physical layer data frames on an Ethernet physical interface, identifying a location of the first code block of each first data frame in the m first data frames by using an alignment marker of a physical layer data frame in the n physical layer data frames, and sending the n physical layer data frames that carry the m first data frames of the code block data stream, where m and n are integers greater than or equal to 1. According to the foregoing technical solution, there is no need to perform framing search in the first data frame, so as to improve efficiency in performing framing in the first data frame, reduce an overhead bit of the first data frame, and reduce system design complexity.

摘要： System and method for implementing a link aggregation system, a protection system, and an XPIC application for an all outdoor radios system using a wireless channel operating at a license-free 60 GHz band are provided. The license-free 60 GHz band offers a wide frequency bandwidth that can support a high speed data rate up to 10 Gbps in full duplex mode, frequency reuse, and high security due to its fast oxygen absorption at 60 GHz. As such, a wireless channel operating at the license-free 60 GHz band may be used for a link aggregation system to support wireless local area network (LAN) connections with the speed up to 7 Gbps. In addition, a wireless connection operating at the license-free 60 GHz band may be used to support both XPIC application and protection system for all outdoor radios to achieve a transmission speed of up to 10 Gbps in a full duplex mode.
