FIELD: physics, computer engineering.SUBSTANCE: invention discloses a method and a system for dispatching an uplink message in gigabit passive optical networks (GPON). The method includes the following steps: configuring a private managed entity for an 802.1p entity, and defining a mapping relationship between a priority queue and a priority of an uplink message in the private managed entity (S100); the 802.1p entity scheduling an uplink message from a user terminal, mapping the uplink message to a corresponding GEM port, and creating a corresponding priority queue according to the mapping relationship between the priority queue and the priority of the uplink message defined in the private managed entity (S101). In the present invention, the uplink messages mapped to the GEM ports in the GPON system can be flexibly scheduled using an N:M bridge-mapping service model, which is a beneficial extension to the existing mode for dispatching an uplink message in the GPON system.EFFECT: enabling one GEM port to determine the number of priority queues to be created when mapping uplink messages with different P-bits.10 cl, 6 dwg |
