Aimed to enhance the supporting ability for diversified services, this paper proposes a hierarchy echo state network(HESE) based service-awareness(SA)(HESN-SA) mechanism in 10 Gbit/s Ethernet passive optical network(10G-EPON). In this HESN-SA, hierarchy architecture is adopted to realize echo state network(ESN) classification based SA. According to the network architecture of 10G-EPON, the parent-ESN(p-ESN) module works in the optical line terminal(OLT), while the sub-ESN(s-ESN) module is embedded in optical network units(ONUs). Thus, the p-ESN plays the main function of SA with a total view of this system, and s-ESN in each ONU conducts the SA function under the control of p-ESN. Thus, resources allocation and transport policy are both determined by the proposed mechanism through cooperation between OLT and ONUs. Simulation results show that the HESN-SA can improve the supporting ability for multiple services.
