Age of information (AoI) has been widely accepted as a measure quantifyingfreshness of status information in real-time status update systems. In many ofsuch systems, multiple sources share a limited network resource and thereforethe AoIs defined for the individual sources should be correlated with eachother. However, there are not found any results studying the correlation of twoor more AoIs in a status update system with multiple sources. In this work, weconsider a multi-source system sharing a common service facility and provide aframework to investigate joint performance of the multiple AoIs. We then applyour framework to a simple pushout server with multiple sources and derive aclosed-form formula of the joint Laplace transform of the AoIs in the case withindependent M/G inputs. We further show some properties of the correlationcoefficient of AoIs in the two-source system.
