Abstract: Aiming at the problem of unbalanced traffic schedule in multiple logical links, a traffic schedule model of logical links is analyzed, and the method of available bandwidth measurement is proposed. In order to depict the load of logical links clearly, the concept of maximum proportion of available bandwidth is drawn. The amount of traffic which is scheduled in special logical link is calculated. Experimental result shows that the algorithm has better ability of traffic schedule, optimizes the character of traffic load balance in multiple logical links and improves the utilization of logical links.


Key words: link bandwidth, traffic schedule, bandwidth detection, load balance
