The approach to RIN message deliveries using web services defined in this standard is asymmetric. Only recipients of RIN messages will need to publish and maintain a web service. Companies sending RIN messages will be able to call these services and thus effect the deliveries of RIN messages. As a consequence it is the sender that determines the speed of the communication.
A further consequence is that the capacity management lies with the recipient of RIN messages who may need to be able to satisfy concurrent (or near concurrent) web service requests from multiple RIN message senders. The number and frequency of such web service requests is likely to vary significantly over time and recipients of RIN messages are advised to plan their infrastructure accordingly.
Wherever this standard only mentions the HTTP protocol, it is to be understood that HTTPS communications are also allowed.
