Embodiment Construction

[0019] The specific implementation of the method of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] In the general data transmission method of the present invention, by setting a frame structure for transmitting data on the physical layer, the bandwidth occupied by the transmission service is controlled at the interface part of the physical layer, and the corresponding bandwidth is dynamically allocated according to needs, Provide a flexible and effective way to realize the reasonable allocation of bandwidth for real-time services and non-real-time services, and carry various data services. There are basically three types of existing network data: IP data, ATM data, and TDM (time division multiplexing) data. Different types of data can correspond to different service types. The existing service types are divided into management information services, real-time Business, non-real-time key business, non-real-...

Abstract

The method comprises: during transmitting data in physical layer, using a data frame structure with a fixed time length to transmit data; said data frame structure comprises fields, frame synchronization, frame initiation and sub-channel bearing data service; according to a preset rule, mapping the service type corresponding to the transmitted data into the sub-channel bearing the data service. By using a frame structure with a fixed time length, the real-time QoS can be ensured, and the bandwidth can be allocated based on the variation the network traffic.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a general data transmission method. Background technique [0002] The communication network has changed from the voice-based synchronous transmission network to the once-dominant asynchronous transfer mode (ATM) network, and now to the IP network with the Internet Protocol (IP) as the core. The proportion of data has dropped rapidly, and at the same time, the huge increase in data throughput has brought enormous pressure to the network. Telecom operators have increased the ability of the network to process data through continuous expansion of physical bandwidth and related technologies, but the increase in physical bandwidth will always lag behind users. For data transmission requirements. [0003] The current communication network carries various services, such as real-time services such as voice, non-real-time critical services such as video and online games, and non-real-tim...
