Dynamic reconfiguration is the action of modifying a software system at
runtime. Several works have been using architectural specification as the basis
for dynamic reconfiguration. Indeed ADLs (architecture description languages)
let architects describe the elements that could be reconfigured as well as the
set of constraints to which the system must conform during reconfiguration. In
this work, we investigate the ADL literature in order to illustrate how
reconfiguration is supported in four well-known ADLs: pi-ADL, ACME, C2SADL and
Dynamic Wright. From this review, we conclude that none of these ADLs: (i)
addresses the issue of consistently reconfiguring both instances and types;
(ii) takes into account the behaviour of architectural elements during
reconfiguration; and (iii) provides support for assessing reconfiguration,
e.g., verifying the transition against properties.Comment: 6\`eme Conf\'erence francophone sur les architectures logicielles
