WAVELENGTH SELECTIVE FOR PACKET TRANSMISSION VIA A PASSIVE OPTICAL NETWORK

摘要

A method and apparatus for transmitting a plurality of IP packets with different traffic quality categories in an Ethernet-passive optical network (100) is disclosed. When an IP packet is received for transmission, the traffic quality category for the packet is determined from a field in an IP header (200) of the packet. An optical wavelength for transmission of the IP packet is then selected based on the determined traffic quality category and the IP packet is transmitted using the selected optical wavelength.
