The described implementations relate to computer networking. One implementation is a method performed using one or more computing devices. The method can include obtaining first performance data reflecting performance by first networking components of a first classification and, based at least on the first performance data, determining a first expected service level of a first redundant configuration of the first networking components. The method can also include obtaining second performance data reflecting performance by second networking components of a second classification, and, based at least on the second performance data, determining a second expected service level of a second redundant configuration of the second networking components. The method can also include providing an evaluation of the first redundant configuration and the second redundant configuration based at least on first expected service level and the second expected service level, and configuring network traffic based at least on the evaluation.
