Quality of Service (QoS) in indirect communication systems

Indirect communication, based in publishers and subscribers, is becoming an alternative paradigm to direct communication. The main advantage of this paradigm relates to the independence of parts involved in communication, which do not need to know where other parts are and, in some architectures, do not even need to be simultaneously active.

However, the architectures providing this service do not have the ability to ensure Quality of Service (QoS) and with indirect communication, traditional QoS mechanisms will be dificult to use, if not impossible, because parts should not know topology and positions involved in communication.

This project intends to produce the necessary changes to the publisher-subscriber model in a way such that QoS should be viewed in an integrated way by applications, provider and data network.
