摘要： According to particular embodiments, determining paths in a network with asymmetric switches includes receiving a graph representing the network. Each asymmetric switch has defined degree connectivity between one or more pairs of degrees of the asymmetric switch. The graph is transformed to yield a transformed graph that accounts for the asymmetric switches. A routing process is applied to the transformed graph to yield one or more paths through the network.
