A network quality control system includes a user control console to probe, calculate, and display the quality of an enterprise's network connections to remote SNMP managed devices supporting real-time services like VoIP. Traceroute-like messages are sent to each remote SNMP managed device to report on the path, and hop latency, jitter, and packet losses. MOS scores are computed to indicate performance with a variety of available codec's. Empty test packets used simply to probe network quality are not used. Instead, SNMP messages that carry valuable information or commands for other purposes are gleaned of timing information so the MOS quality scores can be calculated in background.

This invention provides a fault indication technology used to Ethernet optical fiber transceiver. It includes following step: adds the control circuit in the transceiver, the control circuit is used to test and control the working state of Ethernet electrical interface and optical interface. To implement the fault indication, the control circuit connects to the interface circuit of Ethernet through the LINK signal, through connecting SD and TX-DIS with the optical interface circuit of Ethernet, makes real time test to the state of receiving the optical signal in the optical fiber interface and the state of network connection in the RJ45 interface, and reports the working state of the link according to the result of testing. The control circuit implements the report of the fault indication to the remote equipment through controlling the working state of the optical fiber sending circuit.

A printing apparatus, or a multifunction peripheral connected via a network, can store images having individual identification (ID). The devices can extract inherent identification (ID) from a document and can retrieve, from a storage device, a pre-stored image having identification (ID) corresponding to the extracted identification (ID), and can compose visualized copy-forgery-inhibited-pattern information on the retrieved image and form a composite image on a recording paper.

The invention provides a network connection method, a network connection device and a terminal. The network connection method comprises the steps of judging whether the SSID (Service Set Identifier), BSSID (Basic Service Set Identifier) and connection password of the wireless network access point are correspondingly stored in a preset safe network list or not when a wireless network access point is scanned; obtaining preset authentication information corresponding to the wireless network access point when the judging result is yes, encrypting the preset authentication information through a preset encryption key and sending the encrypted preset authentication information to the wireless network access point; detecting whether the response information of the wireless network access point for the encrypted preset authentication information is received or not; and determining whether to establish connection with the wireless network access point by employing the connection key or not according to the response information when it is detected that the response information is received. According to the technical scheme, the security of automatic connection with a wireless network can be effectively improved, the connection with phishing is avoided, the information security of the user is ensured, and the use safety experience of the user is improved.

The invention discloses an explanation system based on a code with uniqueness and a method of the explanation system. The method includes the following steps that the code which has uniqueness and the scannable characteristic and corresponds to explanation data is generated through the explanation data; the code is manufactured into a material object and placed on the obvious position, where a receiver can conveniently scan the material object, of an explanation unit; an intelligent terminal of the receiver carries out automatic searching and is connected with a network; after network connection, the intelligent terminal scans the code and has access to the explanation data stored in a device. The system and method meet the requirement of the receiver for scenic spots or exhibit explanation on the condition that explanation personnel are not on the spots, the number of the explanation personnel is reduced through the method, cost is lowered, information electronization, visualization and standardization of the explanation data are achieved, continuous long-time benefits are achieved through one-time editing and recording, intermediate links are reduced, and labor cost is further reduced.

A method of controlling network connection, comprising: establishing connection between a security monitored network and a wide area network (WAN); detecting presence status of a first network node in the security monitored network; and adjusting access of a second network node included in the security monitored network to the WAN according to the detection.

A multi-cast download method for downloading an image file is applicable to downloading the image file from an image file server to a computer. The multi-cast download method includes the steps of establishing a wire network connection and a wireless network connection in the computer, in which the wire network connection connects the computer and the image file server; and simultaneously performing a retransmitted packet receiving process and the following steps. The image file is downloaded from the image file server to the computer in a multicast manner by using the wire network connection. When a lost packet is detected, a packet retransmitting request corresponding to the lost packet is sent by using the wireless network connection and Transmission Control Protocol (TIC).

The invention relates to the technical field of data backup, in particular to a snapshot technology combined continuous data protection system. The system includes a client, the client is in network connection with the remote mirror image system; the data transmission module is used for transmitting data in a database. the remote mirror image system is in network connection with the backup storagesystem through a local area network; data in the database can be backed up and stored; wherein the backup storage system is sequentially connected with the snapshot technology system and the server host through a network; the snapshot technology system and the remote mirror image system are combined to realize remote backup; according to the invention, data can be arranged through the control system; according to the data backup method and device, the data can be distinguished according to the importance priority and preferentially transmitted according to the importance level through analysis and classification, the phenomenon that important data are lost due to the fact that the data are very disordered during backup is avoided, important data transmission is guaranteed, the backed-up data can be stored in order, and the use requirement can be met.
