What is a sender-receiver communication?

The sender-receiver pattern gives a solution to the asynchronous distribution of information, where a sender distributes information to one or several receivers. The sender is not blocked (asynchronous communication) and neither expects nor gets a response from the receivers (data or control flow), i.e. the sender just provides the information and the receivers decide autonomously when and how to use this information. It is the responsibility of the communication infrastructure to distribute the information. The sender component does not know the identity or the number of receivers to support the transferability and exchange of AUTOSAR Software Components.
