Abstract: One example method occurs in a test environment comprising network emulation platforms (NEPs), wherein the NEPs implement an emulated switching fabric comprising emulated switches, wherein the NEPs are connected via at least one physical cable. The method includes determining, using a network test system controller, at least one routing path group for communications between the emulated switches, wherein each of the at least one routing path group includes or uses virtual links utilizing one or more lanes of the at least one physical cable; configuring, using the network test system controller, physical ports of the NEPs to assign traffic during a test session to one of the virtual links based on a routing path group identifier associated with the traffic; and initiating, using the network test system controller, the test session involving the test environment.
