Data transmission method and device

Abstract

The application provides a data transmission method and device. The data transmission method and device are applied to a communication system that includes at least one computing device and at least one routing device, wherein at least one container is configured in each computing device, the communication system is equipped with a plurality of container groups, each container group in the plurality of container groups includes at least one container, and one container belongs to only one container group. The data transmission method comprises the following steps: a routing device confirms a first mapping relationship and a plurality of second mapping relationships, wherein the first mapping relationship is used to indicate a one-to-one mapping relationship between the plurality of container groups and a plurality of external identifiers, the plurality of second mapping relationships have one-to-one correspondence with the plurality of container groups, and each second mapping relationship is used to indicate a one-to-one mapping relationship between the plurality of containers of the corresponding container group and a plurality of internal identifiers; and the routing device controls the data transmission between the container and the external device according to the first mapping relationship and the second mapping relationship, so that the communication between the container and the external device can be easily realized.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and more specifically, to a method, device and system for managing network slices. Background technique [0002] A container is a collection of interfaces between components and platforms in an application server. Containers were born with the development of thin client systems. When developing a thin client system, developers have to spend a lot of energy to pay attention to details such as thread safety, transactions, networks, resources, etc., thereby reducing development efficiency. Since these solutions to these details are generally fixed, or only parameters are changed, from the perspective of code reuse and design patterns, developers extract these underlying details to make a platform and provide certain interfaces. In this way, business developers do not need to pay attention to the realization of these low-level details, but focus on the realization of business l...

Problems solved by technology

[0005] Mode 1, the container can use the network information of the computing device (for example, Internet Protocol (Internet Protocol) IP address) to communicate with external devices, but in this mode, when multiple containers are running on the computing device, the multiple containers Sharing the same IP address can easily lead to communication errors. Therefore, this method is not easy to realize the communication between the container and the external device

[0006] In method 2, you can consider assigning independent network information (for example, IP address) to each container. However, with the development of communication technology, there may be a large number of containers in the communication system, resulting in a huge overhead for IP addresses in this method. Therefore, this method is not easy to realize the communication between the container and the external device
