Embodiment Construction

[0038] An embodiment is cited below to illustrate the concept of the present invention. The network packet transmission method of this embodiment is to cut the packet to be transmitted into two packets when the remaining time of the current upload time is insufficient, which is called the first transmission packet and the second transmission packet, and then use the remaining time to transmit the first transmission packet and the second transmission packet. The packet transfer waits for the next uploadable time. However, the cutting of the packet is not carried out blindly, but a conditional judgment, please refer to figure 2 .

[0039] figure 2It is a schematic diagram of packet cutting judgment in this embodiment. In this embodiment, three conditions must be met before the packet 210 to be transmitted is cut. First, the time required to transmit the package 210 must be greater than the remaining time 220 of the current upload time, otherwise there is no need for cutting. ...

Abstract

A method and a device for network packet transmission are characterized in that whether remaining time of current upload time is sufficient for transmission of a network packet is inspected at first; when the remaining time is sufficient, the network packet is directly transmitted; otherwise, the network packet is split into a former transmitted network packet and later transmitted network packet, the remaining time is used for transmitting the former transmitted network packet, and the later transmitted network packet is transmitted when the next uploading time is provided.

Description

technical field [0001] The present invention relates to a network packet transmission method and device, and in particular to a network packet transmission method and device for cutting packets. Background technique [0002] The passive Ethernet optical network (EPON: Ethernet Passive Optical Network) has a bandwidth of up to 1Gbps. It is a shared transmission media network structure, which can greatly reduce the cost of network laying. Due to its high-speed transmission characteristics, many high-speed applications, such as multimedia transmission, voice data, Internet telephony (IP Telephony, where IP is the abbreviation of Internet Protocol), Internet television (IPTV) and high-definition television (HDTV: High-Definition TV) and other applications can be realized on EPON. In the downlink direction, EPON uses the broadcast (Broadcast) method, and in the uplink direction, EPON uses the Time-Division Multiplexing (TDM: Time-Division Multiplexing) method, so that in the sha...
