ITC is the first international conference in networking science practice. In 1955, ITC was founded by enthusiastic scientists and engineers willing to deploy networks in a holistic way. It served as a forum for all theoretical fundamentals and engineering practices for large-scale deployment and operation of telecommunications networks. For long time, ITC was the sole venue that brought together at large scale researchers from industry, network operators and service providers, as well as scientists from academia. These groups are the three strong traditional roots of ITC.
