Quality of service control in Ethernet passive optical networks based on virtual private LAN service technique

摘要

A technique is proposed that allows achievement of logieal point-to-mui-tipoint paths in gigabit Ethernet (GbE) networks with access based on passive optical networks (PONs), guaranteeing upstream/downstream bandwidth and quality of senice also in conditions of traffic congestion. Such a method is based on the combination of the virtual private LAN service (VPLS), implemented in the core network, and the VLAN tagging forwarding process used in the edge-PON segment.
