Abstract: There are a data transmission method, a data transmission system, a Coaxial-cable Line Terminal (CLT) and a Coaxial-cable Network Unit (CNU). The method includes the following steps: setting the uplink transmission period, the length of which is less than or equal to the length of each CNU keeping the clock; each CNU transmits uplink data within the uplink transmission period. The clocks between each CNU and the CLT are always kept synchronous, and the normal communication between the CNUs and the CLT is guaranteed.

Abstract: A method, system and terminal for determining QoS grade, include: oaxial-cable network unit (CLT) assigns the QoS grade for user equipment; the information of assigned QoS grade is sent to the Coaxial-cable network unit(CNU); CNU determines the QoS grade of the data packet sent from the user equipment corresponding to the received information of the QoS grade. And the CLT and CNU therefore are also provided. The CNU can meet the QoS requirement of user equipment, and can also reduce the consumption of the CNU.

Abstract: A method for synchronous time division switch is provided by the present invent, and the said method includes the following steps: with the transmission time of single byte as an unit, the time for receiving and transmitting each Ethernet frame of fixed length in the Ethernet port is divided respectively to input slots and output slots, and the input slots and output slots are numbered respectively in turn; the data is received circularly according to the number of input slots through the Ethernet port; the data received in each input slot is interchanged to the corresponding output slot; according to the number of output slots, the data is transmitted circularly through the Ethernet port. An equipment for synchronous time division switch and two kinds of equipment for the Ethernet switch are also provided by the present invent. By using the method for synchronous time division switch in the present invent and making synchronous time division switch in the Ethernet, the cost of synchronous time division switch will be depressed.

Abstract: A method of Ethernet switching, including: dividing the communication time of output section of every Ethernet port into at least 2 same size time slots, determining the output time slot of the Ethernet port which corresponding to the L2/L3 information of the fixed size Ethernet frame to be exchanged, exchanging said fixed size Ethernet frame to the time-division switching output queue maintained by the determined time slot of the Ethernet port, cyclically outputting said Ethernet frame of the time-division switching output queue maintained by the every time slot via the Ethernet port. An Ethernet switching device is also provided and thus can meet the requirement of transmission delay of same velocity ratio time-division service transmission.

Abstract: A method, physical layer cross-apparatus, MAC layer cross-apparatus, IP layer cross-apparatus and cross-concatenation system for forwarding data in Ethernet are provided. In the method, cross relations between every interface of the Ethernet device are set; after data is received in one interface, whether there is cross relation between the interface receiving data and other interfaces is judged according to the cross relations set; if there is cross relation, the received data will be transmitted to the other interface between which and the interface receiving data there is cross relation; otherwise, existing forwarding processing will be performed. In accordance with the method, cross-apparatus and system, the burden of the Ethernet devices is mitigated, and the forwarding performance of the Ethernet devices is improved.
