Upstream Polling Protocols for Flow Control in PON/xDSL Hybrid Access Networks.
IEEE Transactions on Communications(2016)
摘要
In a hybrid PON/xDSL access network, multiple customer premise equipment (CPE) nodes connect over individual digital subscriber lines (DSLs) to a drop-point device. The drop-point device, which is typically reverse powered from the customer, is co-located with an optical network unit (ONU) of the passive optical network (PON). We demonstrate that the drop-point experiences very high buffer occupan...
