We propose a new two-stage energy-saving scheme allocating the idle time of one ONU's transceiver to other ONUs based on downstream and upstream matching and dividing ONUs into two categories which adopt different energy-saving modes according to their traffic. The simulation results show that proposed scheme can reduce the power consumption and delay of ONUs.
Passive optical network (PON) deployment requires significant capital and operational costs for operators to provide high network capacity and significant geographic coverage. Network sharing is desirable for operators to reduce the investment needed to deploy and operate PON networks. In this paper, we introduce a bandwidth resource sharing framework for XG-PONs among multiple operators. In this...
Passive optical networks (PONs) offer high network capacity and densified coverage at the cost of high capital expenditure. Therefore, it is desirable for network operators who deploy their own infrastructures to share their PON infrastructures to reduce the initial investment. The key problem of PON network sharing is how to balance the trade-off between isolation and utilization of bandwidth resources...
In this paper, we propose a GPON-based transmission hierarchy (GTH) for metro network. Then a simulation testbed is constructed to study the GTH's performance on supporting wireless backhaul service. Simulation results show that, compared with MSTP, GTH reduces the cost of network expansion significantly for its higher transmission efficiency.
