Abstract: Traffic scheduling which aims at improving network resource utilization and network application performance.Currently，much research can be found about traffic scheduling algorithm.However，since logical links in broadband network access are dynamic，real-time and distributed，those scheduling algorithms did not fit for the case well.In this paper，the feature of traffic scheduling in multi logical links is discussed，a model of sharing token buffer traffic scheduling is also designed.A sharing token traffic scheduling algorithm in multi logical links based on feedback information is presented.In this algorithm，the traffic scheduling of links which is based on the feedback information of token numbers in sharing token buffer.Experimental results demonstrate that this algorithm diminish latency，the shape and throughout capacity of traffic is better than other traditional algorithms.

Key words: traffic scheduling, token buffer, feedback, load balancing
