Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a data transmission method, apparatus, device, transmission network management and control system, and terminal.
Background
In order to meet the requirements of the China Mobile 5G network, different service types need to be supported simultaneously, such as large bandwidth, low time delay, hard isolation, flexible connection, unified management and control, high-precision time synchronization and the like, and a new slice transmission network technical system is needed to support the transmission of the 5G service.
The 5G transmission is based on a Slicing Packet Network (SPN) mechanism, and after data enters SPN transmission equipment through a User Network Interface (UNI), data types are distinguished through data classification, and the data enters a Network Node Interface (NNI) forwarding flow.
However, for multi-service access, the SPN needs to support multiple transmission pipes of different services, including 5G, 4G, customer service, home wide, etc., and different transmission pipes need to be configured to meet the needs for different services, which need different transmission levels, relating to bandwidth, delay, jitter, reliability, security, etc.
The current technical solution is to establish an end-to-end transmission channel, configure transmission channel attributes (including bandwidth, priority, etc.), encapsulate a service with a corresponding L2 or L3 transmission label, receive the service at a UNI interface, encapsulate a transmission label related to the service inside an SPN device, send the transmission label to a corresponding NNI interface, and transmit the transmission label in the corresponding transmission channel.
The SPN transmission network equipment receives the service at the UNI interface by establishing various L2VPN or L3VPN channels, encapsulates the related transmission label in the SPN equipment, sends the transmission label to the corresponding NNI interface and transmits the transmission label in the corresponding transmission channel.
Because the establishment of the transmission channel is established according to a transmission network management and control platform, the pipeline transmission of the SPN can have the problem of link interruption, so that the end-to-end service is interrupted; meanwhile, since the transmission channel may enter and exit at the same port, traffic congestion at the port may be caused, which may result in increased traffic delay, increased jitter, and packet loss.

Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different bits which, when joined logically together, comprise the module and achieve the stated purpose for the module.
Indeed, a module of executable code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Likewise, operational data may be identified within the modules and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network.
When a module can be implemented by software, considering the level of existing hardware technology, a module implemented by software may build a corresponding hardware circuit to implement a corresponding function, without considering cost, and the hardware circuit may include a conventional Very Large Scale Integration (VLSI) circuit or a gate array and an existing semiconductor such as a logic chip, a transistor, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.
The exemplary embodiments described above are described with reference to the drawings, and many different forms and embodiments of the invention may be made without departing from the spirit and teaching of the invention, therefore, the invention is not to be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of elements may be exaggerated for clarity. The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. Unless otherwise indicated, a range of values, when stated, includes the upper and lower limits of the range and any subranges therebetween.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
