Problems solved by technology

[0004] However, when establishing slice-based services in existing SPNs, it is necessary to establish end-to-end hierarchical Ethernet SE channels according to the access bandwidth. For example, the average value of access services is 1GE and the peak value is 10GE. One point requires 3 SE channels, occupying 30GE of physical channel bandwidth, but the SE channel can only be occupied by one client, and the time slots in the SE channel are randomly occupied according to the allocated time slots during transmission. For example, 1G traffic entering will also occupy 10G transmission time slot
Therefore, even if the bandwidth and time slot are free, they cannot share the bandwidth and time slot with other clients, resulting in low bandwidth and time slot utilization and inflexible service configuration.

Embodiment Construction

[0063] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0064] In view of the existing SPN transmission, the SE channel can only be occupied by one client, and the time slots in the SE channel are occupied according to the allocated time slots during transmission, which is prone to the problem of bandwidth and time slot idleness, and provides a data The transmission method realizes the time-slotted transmission of the SE channel, effectively utilizes the idle time slot, improves the utilization rate of the SE channel, and realizes flexible uplink and downlink and transmission of services.

[0065] Such as figure 1 Shown, a kind of data transmission method of the embodiment of the present invention is applied to the SPN device of slice packet network, including:

[0066] Step 101, transmit the data to be tran...

Abstract

The present invention provides a data transmission method, device and device, and relates to the technical field of communication. The method, applied to a sliced ​​packet network SPN device, includes: transmitting data to be transmitted to a receiving end through a fixed time slot in a layered Ethernet channel, wherein the layered Ethernet channel is a multi-service data transmission channel. The solution of the present invention, by realizing the time-slotted transmission of the SE channel, effectively utilizes the idle time slot, improves the utilization rate of the SE channel, and realizes the flexible adding and dropping of services and transmission.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method, device and equipment. Background technique [0002] With the development of technology, the fifth-generation mobile communication technology 5G network will support a variety of services and application scenarios, such as enhanced mobile broadband eMBB (Enhanced Mobile Broadband) services with higher bandwidth and lower latency, and support for massive user connections. Internet of Things mMTC (Massive Machine-Type Communication) business, and ultra-high reliability, ultra-low latency communication uRLLC (Ultra Reliable&Low Latency Communication), etc. It is foreseeable that in the 5G era, many new user applications will be introduced, such as: ubiquitous high-definition / ultra-high-definition and even 3D holographic films and videos in dense urban areas, high-speed user experience of 100Mbps anywhere, and high-speed traffic greater than ...
