摘要： A method for network tapping and packet brokering in wireless networks includes tapping a signal in a wireless network and determining whether the signal is a valid signal according to a wireless network protocol. In response to determining that the signal is a valid signal according to the wireless network protocol, the signal is demodulated into a sequence of bits arranged according to the wireless network protocol. In response to determining that the signal is not a valid signal according to the wireless network protocol, an indication that the signal is not a valid signal according to the wireless network protocol is generated. A packet in a format compatible with a network tapping and packet brokering system is generated. At least some of the bits or the indication is inserted in the packet. The packet is transmitted to the network tapping and packet brokering system.

摘要： Methods, systems, and computer readable media for monitoring and/or testing network communications are disclosed. A method for monitoring network communications includes receiving packets from a network connected device, determining features associated with either the network connected device or a communications network to which the network connected device is connected by actively or passively monitoring or testing the packets, and automatically switching between passively monitoring or testing the packets and actively monitoring or testing the packets in response to receiving a packet carrying instructions.

摘要： A system for providing test receive port resiliency includes a network equipment test device including a port module for transmitting test packets to and receiving packets from a device under test (DUT). The system further includes a port central processing unit (CPU) associated with the port module for processing packets that the CPU receives from the DUT. The system further includes a configurable pre-filter associated with the port module for pre-filtering the packets to prevent at least some of the packets from being forwarded to the port CPU. The system further includes a pre-filter rules generator for analyzing the packets forwarded to the port CPU and for automatically generating a pre-filtering rule to be used by the pre-filter for filtering subsequent packets received from the DUT.

摘要： A method for validating a network packet broker is disclosed. The method includes configuring in software at least one of a on filter and a load balancer, processing a packet capture file containing data packets using the at least one filter and the load balancer such that data packets processed is output from an output port of the network packet broker. The method also includes analyzing, using a protocol analyzer, the data packets output by the output port of the network packet broker to validate the network packet broker.

摘要： Methods, systems, and computer readable media for receiving test configuration information are disclosed. According to one exemplary method, the method occurs at a node configured to operate in a private network. The method includes registering node identification information with a registration server. The method also includes sending a keep-alive message to the registration server. The method further includes receiving, in response to the keep-alive message and via the registration server, test configuration information from a configuration system outside the private network.

摘要： Methods, systems, and computer readable media for obtaining power consumption data associated with packet processing are disclosed. One method for obtaining power consumption data associated with packet processing occurs at a test device. The method includes sending, via a first communications interface, at least one test packet to a system under test (SUT). The method also includes receiving, via a second communications interface, power consumption data associated with the at least one test packet. The method further includes correlating the power consumption data and test packet information.

摘要： Systems and methods are disclosed herein to provide improved data communication test systems for the testing of wireless data communication devices and systems. A flexible arrangement of physical layer interfaces, hardware traffic generator/analyzers and software traffic generator/analyzers is disclosed that partitions the data communication test system into interfacing and processing modules. Such a system may offer improved capabilities such as a lower-cost and more efficient test system, a reduction in redundant processing capabilities, and a dynamic balancing of interfaces and processing power.

摘要： A method for transmitting and coherently detecting data transmitted over electrical lanes that experience different amounts of skew includes, at a traffic generation or forwarding device, self calibrating transmit and receive-side components of the traffic generation or forwarding device to account for skew between electrical lanes and setting per-electrical lane delays based on the calibration. Data to be transmitted to a network device is generated. The data to be transmitted is spread, using one of the transmit-side components, over a first number of electrical lanes. The data is multiplexed from the electrical lanes onto a second number of optical lanes, the second number being different from the first number. Data is transmitted to and received from the network device over the optical lanes. Transmitted data is reconstructed from the received data using the receive-side components.

摘要： Network tool optimizers for server cloud networks and related methods are disclosed. In part, master filters are defined to segregate and control user traffic, and user filters are defined to forward the user traffic to cloud-based network tools or tool instances. A master user interface and user interfaces for each user are provided so that the master filters and user filters can be defined and managed. A filter rules compiler within the cloud-based network tool optimizer then combines the master filters with the user filters, resolves conflicts in favor of the master filters, and generates filter engine rules that are applied to filter engines within the network tool optimizer for the cloud network. The filter engines then forward packets received at input ports for the network tool optimizer to output ports for the network tool optimizer that are coupled to network tools or tool instances within the cloud network.
