摘要： Aspects include receiving, at an input/output (I/O) processor, a transport control word (TCW) that includes an instruction to perform physical port mirroring. It is identified, by the I/O processor, a first port to be mirrored and a second port to perform the mirroring. The second port is a physical port on a host bus adapter (HBA). In response to outbound data being sent to the first port for transmission to a first target device and to the instruction specifying outbound port mirroring, the I/O processor sends a copy of the outbound data to a second target device via the second port. In response to receiving inbound data at the first port and to the instruction specifying inbound port mirroring, a copy of the inbound data is transmitted to the second target device via the second port.

摘要： A packet control device includes a processor that receives a first packet to be input or output through a port. The processor determines whether the first packet is to be mirrored. The processor determines, upon determining that the first packet is to be mirrored, whether the first packet has been mirrored, based on a value of an area of the first packet. Upon determining that the first packet has not been mirrored, the processor generates a second packet by duplicating the first packet, sets a first value indicating completion of mirroring to the area of the second packet, transfers the second packet to a transfer destination, and transmits the first packet to a transmission destination. Upon determining that the first packet has been mirrored, the processor sets a second value indicating incompletion of mirroring to the area of the first packet, and transmits the first packet to the transmission destination.

摘要： A method and device for forwarding a packet are disclosed. When a first access device connected with a database server is to be configured with a mirror image rule, an SDN controller can transmit a mirror image rule adding message carrying the mirror image rule to the first access device. Where, the mirror image rule comprises an IP address of the database server, a MAC address of a database audit device connected with a second access device and a VXLAN tunnel between the first access device and the second access device. When receiving a database access packet whose destination IP address is an IP address of the database server, the first access device may replace a destination MAC address of a mirror packet for the database access packet with a MAC address of the database audit device according to the mirror image rule and forward the encapsulated VXLAN packet.

摘要： A system and method are disclosed for forwarding data in hybrid wireless mesh networks. The method includes configuring a number of mesh network nodes as potential relay nodes (PRNs) in an overlay network associated with a hybrid wireless mesh network, streaming data packets from a source node to a destination node using a native data forwarding algorithm of the hybrid wireless mesh network, dynamically identifying relay nodes (RNs) among PRNs in the overlay network, creating secondary paths for sending data packets towards selected RNs in the overlay network, and relaying data packets from RNs to the destination node using the overlay network.

摘要： The present invention provides a method for stream testing by a switching hub including the steps of generation a test data stream by the switching hub and testing a plurality of DUTs by using the test data stream. A first port of the switching hub transmits port mirroring to a second port of the switching hub. A packet is transmitted through a physical cable from the first port. The first port and the second port are added to a first virtual local area (VLAN) in a native manner. The second port receives a test packet in a self-loop mode. The test data stream is created by repeatedly transmitting the test packet from the second port. In addition, the present invention further provides a system for stream testing by a switching hub.

摘要： A network traffic monitoring apparatus and method of monitoring network traffic on a network path is disclosed. The apparatus comprises a first path arranged to receive a portion of the network traffic from the network path and a monitoring port arranged to monitor the portion of network traffic. The apparatus further comprises a switch having an input port communicatively coupled to the first path, and an output port communicatively coupled to the monitoring port. The switch is arranged to selectively toggle between the first state in which the portion of network traffic can pass from the input port to the output port and a second state, in which the portion of network traffic is prevented from passing from the input port to the output port, in dependence of a switching signal. The apparatus further comprises a second path for communicating a monitoring status signal to a network device.

摘要： A system and method of processing management frames implement a switching strategy is disclosed. In one embodiment, a method of processing frames received in a network switch comprises identifying control frames from the received frames, wherein a control frame includes instruction messages, and identifying non-control frames that include data traffic. For identified control frames, the control frames are modified by inserting a value for an EtherType within the control frame. The value of the EtherType is not inserted within the non-control frames. The method transmits the frames to a central processing unit (CPU) or other frame processing device within the network switch wherein the CPU is configured to identify the control frames from the non-control frames by the value of the EtherType in the frames.

摘要： A method for providing location independent dynamic port mirroring on distributed virtual switches is disclosed. A controller is provided to configure one or more virtual switches within a group of physical machines to appear as a set of distributed virtual switches. In response to the receipt of a data packet at a port of a physical machine, a determination is made whether or not the port has a monitor port located on the physical machine. If the port has a monitor port located on the same physical machine, a copy of the data packet is sent to the monitor port of the physical machine. If the port has a monitor port located on a different physical machine, a copy of the data packet along with an identification (ID) of the port and an ID of the monitor port are encapsulated, and the encapsulated information are sent to a controller.
