The International Conference on Dependable Systems and Networks (or DSN) is an annual conference on topics related to dependable computer systems and reliable networks. It typically features a number of coordinated tracks, including the Dependable Computing and Communications Symposium (DCCS), the Performance and Dependability Symposium (PDS), several workshops, tutorials, a student forum, and fast abstracts. It is sponsored by the IEEE and the IFIP WG 10.4 on Dependable Computing and Fault Tolerance. DSN was formed in 2000 by merging the IEEE International Symposium on Fault-Tolerant Computing (FTCS) and the IFIP International Working Conference on Dependable Computing for Critical Applications (DCCA). The instance number for DSN is taken from FTCS which was up to its 29th instance in its last year of 1999.
