  We evaluate the downstream performance of our novel interoperator
fixed-mobile network sharing, in which operators exchange data in their access
networks. We propose a performance evaluation algorithm, and report credible
performance evaluation results obtained for 204600 randomly-generated passive
optical networks. We show that with the proposed sharing, operators can
increase their access network performance even twofold with software-defined
upgrades, and with no or minimal new hardware required.
