example 1

[0102] The priority number of instance 1 in aggregation group 1 is 16, the priority number of instance 1 in aggregation group 2 is 4096, and the priority of instance 1 in aggregation group 1 is higher.

example 2

[0103] The priority number of instance 2 in aggregation group 1 is 4096, the priority number of instance 2 in aggregation group 2 is 16, and the priority of instance 2 in aggregation group 2 is higher.

[0104] After running the multi-instance spanning tree protocol, use the priority vector of CIST2 {CIST root bridge ID, CIST external root path cost, CIST domain root BID, CIST internal path cost, CIST specified bridge BID, CIST specified aggregation group PID, CIST receive aggregation Group PID} and the priority vector {MSTI domain root BID, MSTI internal path cost, MSTI designated bridge BID, MSTI designated aggregation group PID, MSTI receiving aggregation group PID} with the priority vector of MSTI1 instance, compare the priority vectors. Establish the relationship between NNI port number, aggregation group number, spanning tree instance number, VLAN number, QINQ number, and link direction. When the link is normal, the data packet corresponding to instance 1 is sent through...

Abstract

The present invention relates to the field of Ethernet passive optical network technology, and provides a method and system for sending data packets based on a GPON system. The method includes: receiving data packets sent by each optical network unit ONU, and temporarily storing the received data packets in advance In the configured receive buffer; obtain the relationship between the port, the destination MAC and the link direction, and transfer the data packets belonging to the same direction in the receive buffer to the corresponding same direction buffer; The data packets in the area are analyzed to generate a port data sending pointer linked list; according to the generated port data sending pointer linked list, the data packets in the same direction buffer are sent to the corresponding port buffer, thereby realizing link Send data packets to multiple ports in a loop-free and load-balanced manner. When a link fails, other links provide backup to improve the reliability and efficiency of sending data packets.

Description

technical field [0001] The invention belongs to the technical field of Ethernet passive optical network, and in particular relates to a method and system for sending port data packets based on a GPON system. Background technique [0002] Ethernet passive optical network (Gigabit-Capable PON, GPON) technology is a point-to-multipoint passive optical network access technology based on Ethernet technology, which integrates the easy maintenance and low cost of Ethernet technology and PON network It is the best way to realize the optical fiber access network. [0003] With the acceleration of the integration of the three networks and the process of fiber optic access to the home, the GPON system is widely used, and the demand for broadband Internet access, video on demand, and online games is increasing, and the number of users is huge. Under the premise of certain GPON system resources, there is a delay in the content such as the video requested by the user, and the online game...
