Adding Priorities to Total Order Broadcast Protocols


Group communication and total order topics have been studied for more than two decades from both a theoretical and a practical point of view. Most of this work is concerned about the classical definition of total order (informally, all the messages are received in the same order). However, in some cases additional guarantees are needed, like optimistic delivery or priority-based delivery, which allows a user application to prioritise the sending or even the delivery of certain messages. In this paper, we present several techniques to modify an existing total order protocol to take into account message priorities and show how existing total order algorithms can be modified according to these techniques.
