<p>In a distributed context, mutual exclusion algorithms can be divided into two familiesaccording to their underlying algorithmic principles: those that are permission-based andthose that are token-based. Within the latter family, a lot of algorithms use a rooted treestructure to move the requests and the unique token. This paper presents a very generalinformation structure (and the associated generic algorithm) for token- and tree-basedmutual exclusion algorithms. This general structure not only covers, as particular cases,several known algorithms, but also allows for the design of new ones that are well suitedfor various topology requirements.</p>
