In this case, the sender did not get a successful response. Then, the sender may try to send the same message again even though the receiver received the messge. I guess MSB inherits the HTTP/HTTPS messaging reliability issue. I will contact Huabing off-line. 14:36:17 #topic Modeling subcommittee 14:37:24 #info There are several sub topics here. 14:38:15 #info The first subtopic is Service IM 14:45:06 #info next sub-topic is resource IM 14:45:24 #info PNFD is not defined yet, but it is consiered as a resource IM. 14:49:42 #info there were questions about the relationship between the service and the service component.
