A technique efficiently manages bandwidth (BW) for multipoint-to-multipoint (MP2MP) services in a provider network of a computer network. According to the novel technique, each bridge having a user-network interface (UNI) port of an MP2MP service generates a registration for the service that carries maximum BW values for each port direction (e.g., for each {service, priority, color} triple), e.g., as defined by a Service Level Agreement (SLA). The registrations are advertised among neighboring bridges throughout the network toward other UNI ports of the MP2MP service. As each bridge receives registrations from each neighboring bridge (or from the UNI port), the bridge advertises registered BW values pertaining to a particular direction on a particular one of its ports that correspond to the sum of the BW values for that direction received on all of the other ports of the bridge, up to a maximum BW value (e.g., configured or physical) for the particular port. The actual BW required for allocation on an active port for each direction is the lower of either the registered value advertised from the port in a particular direction or the registered value received at the port in the opposite direction.

The present invention discloses a method for the transmission of the downward flow control information in a gigabit-capable passive optical network (GPON) system. After a medium access control chip (MAC) of an optical line terminal (OLT) receives the flow control information, a transmission container bandwidth (T-CONT) prepared for each optical network unit (ONU) reduces the upward authorization time slot obtained by the T-CONT of each ONU through a dynamic alignment, thus reducing an upward band width, thereby accusing the reduction of the upward data stream of the ONU, and a flow control frame is further generated because the slow queue inside the ONU is on the increase. When the flow control frame of the ONU notifies the user to transmit upward data through a user network interface (UNI), the data packet is not dropped until the UNI accesses according to a certain strategy, thus the upward band width of the ONU is effectively reduced, and the congestion phenomenon of the data stream of the OLT uplink port is eliminated.

The method simplifies the operation of the VLAN Tag, can flexibly expand operation mode of the VLAN Tag, and can conveniently realize diversified VLAN Tag operation mode.

The present invention relates to a packet switched communications network especially to an Ethernet network in which User Network Interfaces (UNI) are standardized between client network (202) and core network (203) with a number of UNI service attributes. In one aspect of the invention a method is used in current packet switched nodes implementing a policer function. The task of the function is to decide whether packets with high drop preference need to be dropped or not due to resource shortage on the given interface. All outgoing packets at a given port will undergo this policer (401) irrespective of the source, destination, identification codes or traffic class. Policer (401) drops packets with high drop preference in one traffic class before a packet of low drop preference is dropped in any other traffic class, and drops packets with high drop preference before a packet of low drop preference is dropped in the same queue. In the course of dropping packets, policer (401) prevents the reordering of packets with low drop preference and packets with high drop preference within the same flow.
