Control Message Aggregation in Group Communication ProtocolsSuch feedback is typically sent as control messages by receiver nodes. Since sending of control messages involves communication overhead, many protocols rely on aggregating a number of control messages and sending them together as a single packet over the network. On the other hand, the delays in th

Church-Rosser Languages vs. UCFLroblem is solvable in polynomial time. In this paper we concentrate on the class of Church Rosser Languages (CRL), the “deterministic counterpart” of GCSL. We prove the conjecture (stated in [.] that the set of palindromes is not in CRL. This implies that CFL∩co-CFL as well as UCFL∩co-UCFL are not i

On the Construction of Reversible Automata for Reversible Languagesffective construction of a reversible automaton for a reversible language was still unknown. We give in this paper a method to compute a reversible automaton from the minimal automaton of a reversible language. With this intention, we use the universal automaton of the language that can be obtained

We define the multicast aggregation problem and design efficient online algorithms for it, both centralized and distributed.
