We investigate and quantify the benefits of multipath routing in a wide-area distributed environment which includes inter-domain routing issues. In this context, we discuss two possible multipath routing schemes and focus on the viable solution for distributed data-intensive applications with high bandwidth and delay requirements. The network topology aggregation is extended for end-to-end multipath computation. An ILP-based algorithm and a heuristic algorithm are proposed with multiple constraints, including bandwidth, delay and memory size. Numerical and simulation results show that the proposed multipath routing algorithms are feasible, and especially well-suited for emerging applications with extremely high bandwidth requirements.
