Embodiment 1

[0050] In the method for data transmission between cards provided in Embodiment 1 of the present invention, the principle of realizing data transmission between cards is as follows: Figure 5 shown. Figure 5 What is shown in is a distributed system including at least two boards, one of which is the main control card and the other is the service card. Each board includes several business modules, such as Figure 5 Both the main control card and the service card shown in include service module A, service module B, ... service module N and so on. Take each service module on the main control card as the service sending end, and each service module on the service card as the service receiving end, of course, take each service module on the service It is also possible for each service module on the card to serve as a service receiving end, wherein at least one service sending end and at least one service receiving end can form an inter-card data transmission system. For the conv...

Embodiment 2

[0082] The inter-card data transmission method provided by Embodiment 2 of the present invention describes in detail the respective specific operation procedures of the service sending end and the service receiving end during the inter-card data transmission. in:

[0083] The operation process of the service sender during data transmission between cards is as follows: Figure 7 shown in Figure 5The business system shown in is taken as an example. In order to ensure that the data synchronization of business N is started only after the data synchronization of business B is completed, the business A that plays a controlling role is generally implemented by the control module in the system. For example, the existing technology example hot-swap modules mentioned in the Figure 5 Take the service sender A sending special control data as an example, the process includes the following steps:

[0084] Step S101: The service sender A starts the process of sending data.

[0085] For...

Abstract

The invention discloses a data transmission method, a data transmission device, a data transmission system between cards, a board card and a distributed system. The method comprises that: when transmitting service data per se, a service transmitting end packages the service data into service messages and transmits the service messages through a data transmission channel of the service per se; when transmitting special control data for controlling other services, the service transmitting end packages the special control data into attribute identification-containing service messages and transmits the service messages through the data transmission channel of the controlled service; a service receiving end receives the service messages through the data transmission channel of the service per se and forwards the service messages to other service receiving ends corresponding to the attribute identification when determining that the service messages comprise the special control data according to the attribute identification contained in the service messages. The method can guarantee the sequential dependence of the data transmission, and the problems of data transmission fault, loss and disordered service processing logic and the like are solved.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a data transmission method, device and system between cards, a board and a distributed system. Background technique [0002] In the distributed system, inter-card communication, or inter-processor communication (Inter-Processor Communication, IPC), realizes data transmission between cards, and realizes data transmission between the main control card and the service card. Inter-card communication also includes: the communication mechanism between multiple processes in the same operating system in a single-core system; the communication between multiple cores on the same chip in a multi-core system; the communication between multiple devices in a network distributed in different regions in a cluster system Communication; communication between multiple cards in the same chassis in a chassis-type distributed system, etc. [0003] Taking the data transmission between the ma...
