Traffic Engineering (TE) leverages information of network traffic to generatea routing scheme optimizing the traffic distribution so as to advance networkperformance. However, optimize the link weights for OSPF to the offered trafficis an known NP-hard problem. In this paper, motivated by the fairness conceptof congestion control, we firstly propose a new generic objective function,where various interests of providers can be extracted with different parametersettings. And then, we model the optimal TE as the utility maximization ofmulti-commodity flows with the generic objective function and theoreticallyshow that any given set of optimal routes corresponding to a particularobjective function can be converted to shortest paths with respect to a set ofpositive link weights. This can be directly configured on OSPF-based protocols.On these bases, we employ the Network Entropy Maximization(NEM) framework anddevelop a new OSPF-based routing protocol, SPEF, to realize a flexible way tosplit traffic over shortest paths in a distributed fashion. Actually, comparingto OSPF, SPEF only needs one more weight for each link and provably achievesoptimal TE. Numerical experiments have been done to compare SPEF with thecurrent version of OSPF, showing the effectiveness of SPEF in terms of linkutilization and network load distribution.
