Abstract: A data transmission method, Coaxial-Cable Network Unit (CNU) and Coaxial-Cable Line Terminal (CLT) are provided. The data transmission method comprises: saving the upward receiving scramble and the upward transmitting scramble, and saving the downward receiving scramble and the downward transmitting scramble, wherein, the upward receiving scramble and the downward receiving scramble are different; the CLT acquires the upward receiving scramble and uses it to decrypt the data encrypted by the CNU using the upward transmitting scramble; the CNU acquires the downward receiving scramble and uses it to decrypt the received data. In the present invention, CNU comprises scramble-acquiring unit, decryption performing unit and data interacting unit. CLT comprises scramble-processing unit, decryption performing unit and data interacting unit. By the invention, the security of the upward data transmission in the Ethernet Passive Coaxial-Cable Network (EPCN) system can be guaranteed, and the quality of service can be significantly improved.

Abstract: An Ethernet receiving and sending device and an Ethernet transmitting method are disclosed. The receiving and sending device detects the level amplitude of the received analog signal, and adjusts the coefficient of amplifying self-adapting according to the result of the detecting so as to make the output level amplitude of the received analog signal amplified be same and be sent to the MAC level of the Ethernet after AD convening and coding and decoding process. And the signal level sent to the coaxial network is amplified and output, the coefficient of amplification is determined by the largest attenuation loss among the coaxial terminals. The receiving and sending device realizes the intercommunication between the access point of the Ethernet and each coaxial terminal and the intercommunication of each coaxial terminal, and thus makes the CSMA/CD MAC layer of the Ethernet can be used in Broadcasting Coaxial Networks environment.

Abstract: A configuration method for Ethernet data transmission, a configuration system for Ethernet data transmission and a transceiver device for Ethernet data transmission in coaxial distribution network are provided. The present invention considers fully the decline between the Ethernet access point and the coaxial terminal when calculating the transmission and reception parameters of the physical layer. Thus the decline of the transmission signal of the Ethernet can be compensated, in order to ensure the passage of the physical layer between the ehternet access point and the coaxial terminal. Since the decline between the coaxial terminals have also been considered when calculating the transmission and reception parameters of the physical layer, the calculated transmission and reception parameters can ensure the close of the physical layer between the coaxial terminals.

Abstract: A network performance testing method comprises: emulating one similar test service flow with the service flow required of testing; transmitting the test service flow from the testing origin node to the testing end node in the network; testing the network performance based on the received test service flow at the testing end node; or after processing the received test service flow, looping back it to the testing origin node to perform the backtracking service test. The invention also discloses a testing origin node network device, a testing end node network device and a network performance testing system, which comprises the testing origin node network device, the testing end node network device and the testing management device connected through the network link each other. Using the invention, the test based on the actual wideband network service application is realized. Consequently, the network failure is judged and located roundly, quickly and accurately. The subscriber service quality and the network availability are improved.
