Embodiment 1

[0032] A method for obtaining transmission performance evaluation data for data distribution services in this embodiment, such as image 3 As shown, perform the following steps:

[0033] Step 1, association matching;

[0034] Publishers and subscribers in each application involved in the data distribution service are matched through topics;

[0035] Step 2, data transmission;

[0036] Obtain the transmission performance evaluation parameters of a single data transmission from the publisher to the subscriber based on the RTPS message and the RTPS protocol standard;

[0037] RTPS messages include data sub-messages, heartbeat sub-messages, confirmation sub-messages and timestamp sub-messages;

[0038] Wherein, there is a timestamp sub-message carrying at least one timestamp before the confirmation sub-message of the message in the data transmission;

[0039] Step 3, obtaining transmission performance evaluation parameters;

[0040] Obtain transport performance evaluation par...

Embodiment 2

[0052] This embodiment is basically the same as Embodiment 1, except that the round-trip time delay of this embodiment is more accurate than that of Embodiment 1, and the effects of factors such as performance and scheduling on the time delay are considered. Such as Figure 6 As shown, the data sender sends a message carrying a time stamp (T1), data and heartbeat at time T1. The data reader receives at time T2 and records T1 and T2. The data reader replies with a message carrying a timestamp (T1, T2, T3) and confirmation at T3, and the data sender receives it at T4 and calculates that the round-trip delay between the data sender and the data reader is T4 -T1-(T3-T2). That is to exclude the delay caused by the non-immediate transmission of the data reader due to various reasons, so as to show the round-trip delay that has nothing to do with external factors and is completely based on the deployment of the data distribution service, so as to provide a reference.

Abstract

The invention relates to a method for acquiring transmission performance evaluation data for a data distribution service, and belongs to the field of communication transmission. The method comprises the following steps: step 1, association matching; step 2, data transmission; and step 3, acquiring transmission performance evaluation parameters. According to the invention, in the scene of data distribution service, the data transmission performance evaluation and acquisition method with low operation overhead, low network overhead, real-time performance, comprehensive coverage and low complexity is realized. On the basis of a standardized interoperability protocol RTPS (real-time publish-subscribe protocol) of a data distribution service, a plurality of sub-messages in twelve different sub-messages to which the RTPS belongs are selected to be modified. On the basis of not changing the original protocol specification, the data interaction process is realized, and meanwhile, the data related to the transmission performance can be obtained at the transceiving end.

Description

technical field [0001] The invention relates to a method for acquiring transmission performance evaluation data for data distribution services, belonging to the field of communication transmission. Background technique [0002] The full name of DDS is Data Distribution Service, that is, data distribution service. It is a new generation of distributed real-time communication middleware technical specification formulated by Object Management Group (OMG) on the basis of HLA and CORBA standards. This specification standardizes the interfaces and behaviors of data publishing, transmission and reception in distributed real-time systems, defines a data-centric publish-subscribe (Data-CentricPublish-Subscribe) mechanism, and provides a platform-independent data model. DDS defines the data transmitted in the distributed network as a topic (Topic), and defines the data generation and receiving objects as a publisher (Publisher) and a subscriber (Subscriber) respectively, thus forming ...
