The convergence of communications, caching and computing (i.e., 3C) has attracted a lot of interests recently. To save communication resources, caching has been introduced into information-centric communication networks. Meanwhile, computing has also been exploited to improve the efficiency of communication networks. However, the combination of both communication, caching and computing is still at its infancy and significant research challenges remain to be addressed. Different from the previous works, we consider a virtualized 3C network, in which multiple service providers (SPs) are able to share the physical resources (i.e., bandwidth, storage and computation resources) from the same infrastructure provider (InP), and the users can dynamically choose the services from different SPs to maximize their utility. The dynamics of resource sharing between multiple SPs and users are modeled via a game theoretical approach. More specifically, the evolution and the dynamic behaviors of users are modeled as an evolutionary game. The competition among the SPs is formulated as a non-cooperative game, and an iterative algorithm is proposed to obtain its Nash equilibrium. Simulation results are presented to show the dynamics and equilibrium of the proposed game model.
