The present invention discloses a method and an instrument of forwarding the message, which belongs to the information area. The method includes: receiving the information, and collecting the key words in the message, then searching the first kind of stored space for the key words to see whether there is the sentence corresponding to the key words, if yes, then forwarding the messages according to the sentence; otherwise, search the second kind of stored space for the key words to see whether there is the sentence corresponding to the key words, if yes, then forwarding the messages according to the sentence in the second kind of stored space. The instrument comprises: receiving and getting the module, searching for and forwarding the module. Using the mechanism of combination of multi-class hash table and TCAM to realize the speediness forwarding and balance of content of the stored message and the forwarding velocity, reducing the message conflicting and make the sentence to reduce to satisfy the requirement of content and velocity of the operation business, which reduces the cost.

The invention discloses a CE dual-homed link protection method in MPLS L3VPN and a system thereof. The method comprises the following steps: ARP items of a target CE are configured on a main PE and a standby PE; the main PE generates an interface FRR relation table of a direct connecting network segment route which reaches the main PE and the target CE; simultaneously, the main PE and the standby PE generate a host route forwarding table according to static ARP items, and the main PE generates a corresponding subnet route forwarding table according to the interface FRR relation table; after detecting that a link state between the main PE and the target CE changes, the main PE switches the interface FRR relation table into a standby path or switches the interface FRR relation table back into a main path, and updates related information in a subnet routing table and a host routing table; after receiving a data flow, the main PE obtains present effective out interface information from the present host route forwarding table or subnet route forwarding table, and forwards the data flow to reach the target CE. By employing the method and the system of the invention, the rapid switching of the data flow can be effectively realized.

A portable electronic device includes a communication component, an integral display operatively connected to the communication component, an operator input component operatively connected to the display and a processing component operatively connected to the communication component, to the display and to the operator input component. The communication component communicates with external electronic devices via a common software interface to send data to and receive data from the devices and to send control signals to the devices to control the operation of the devices. The processing component processes an operator's input to the operator input component and data received by the communication component to formulate the control signals. A method of controlling external electrical components is also provided.

In a method for the error-monitored transmission of data via interfaces of a multi-step communication system, the data is transmitted from a transmitter station to a data-receiving station via at least two relay stations which are connected therebetween and receive and further transmit the data parallel to each other. The data is retransmitted if the transmission has been insufficient due to a request from the receiver end and / or due to the lack of a confirmation from the receiver end. In order to increase performance while reducing power consumption of the system, the request or confirmation is generated only by the receiver station and is sent back to the transmitter station. The relay stations consequently do not generate any confirmations or requests.

The invention provides a data transmission method based on a virtual gateway, a data transmission device based on the virtual gateway, a computer readable storage medium and electronic equipment, andrelates to the technical field of computers. The method comprises the following steps: receiving a data packet; transmitting the data packet to an open virtual switch and a kernel protocol stack through a receiving port of a virtual gateway according to an internal circulation path of the data packet, the virtual gateway being created by configuring a single root virtualization function in a physical network card; determining a forwarding rule of the data packet through the open virtual switch; determining a target address of the data packet through the kernel protocol stack; and transmittingthe data packet to a sending port of the virtual gateway according to the forwarding rule, and sending the data packet to the target address through the sending port. The data transmission performanceof a gateway node can be improved, the system cost is reduced, and the system flexibility is enhanced.

A method to wirelessly network a sensor / actuator node is described. The sensor / actuator node is installed in a sensor / actuator node network and arranged in a hierarchical manner with a plurality of node levels and a cluster head network. A unique node identifier is assigned to the sensor node and the sensor node network is initialized. The sensor node is woken-up to perform a task and then set to an active low power mode.

A soft crawling robot comprises a body and multiple wedge-shaped hard friction sheets, wherein the wedge-shaped hard friction sheets are fixedly connected to the body; the body is made of a flexible material; the integral shape of the body is similar to a bow shape; a bow-like sealed gas chamber and a vent opening which is in communication with an external driving gas source are formed in the body; during inflating, the body swells; under the restrictions of the wedge-shaped hard friction sheets, the right end of the body moves to the right relative to the left end of the body; during deflating, the body retracts; and under the restrictions of the wedge-shaped hard friction sheets, the left end of the body moves to the right relative to the right end of the body. According to the soft crawling robot, due to the bow-like integral layout and the bow-like gas chamber, faster swelling deformation during deflating and faster closure deformation during deflating can be guaranteed to be convenient for the soft robot to more rapidly move ahead.

The invention provides a congestion control method and a device; the method comprises the following steps: detecting whether an output port queue with enabled quantification congestion notification has congestion or not; determining whether a first message of the output port queue carries an emergency label or not when the output port queue has congestion, wherein the emergency label represents a present business is emergent; increasing forwarding amount of the first message when the first message carries the emergency label. The method and device can realize fast forwarding of the message matched with the emergency business from a congestion point device to a data flow terminal.

The invention discloses a method for improving the concurrency of a WEB security gateway. The method is implemented on gateway equipment, and the gateway equipment is positioned between a client and a WEB site server. According to the method, a plurality of virtual gateways are simulated on a physical gateway by a virtual technology, a data distributing component is operated in a host system, and hyper text transfer protocol (HTTP) request data packets are intercepted and transmitted, so that a virtual gateway cluster is realized on a piece of physical equipment. By the method, the problems that the concurrent processing capacity of the gateway is low and the utilization rate of system hardware resources is low because a speed of processing application layer data packets is low in the WEB security gateway are mainly solved.
