The coined DSIN paradigm is envisioned to be an integrated high speed self-organizing hypernetwork consisting of the terrestrial ground-based information networks and the outer space-based entities to provide maximum network capacity. In this paper, we address the challenges of dynamic routing with bandwidth constraint over intermittently connected Deep Space Backbone Layer (DSBL) of DSINs under scheduled contacts. Firstly, we build up hypergraph model to represent DSBL aiming to improve network connectivity. Taking into account the continuous and random changes of selfish traffic along backbone links as well as the selfish forwarding of joint nodes, we propose a noncooperative dynamic routing model with bandwidth constraint, in which routing decision is related to the continuous-time resource usage. Our routing model includes two effective sub-models: stochastic differential game based noncooperative forwarding model with bandwidth constraints and contact schedule model. In addition, we provide a polynomial time algorithm to describe the procedure of our routing model. This algorithm covers three sub-algorithms considering three different cases based on hypergraph model, i.e., internal forwarding, cross-IS forwarding, cross-island forwarding. Theoretical analysis and numerical results demonstrate the effectiveness and feasibility of our routing model.
