TRAFFIC MANAGEMENT APPARATUS AND TRAFFIC MANAGEMENT METHOD FOR CONTROLLING TRAFFIC CONGESTION

摘要

A traffic management apparatus and a traffic management method are disclosed. The present invention relates to the traffic management apparatus comprising: a hierarchical queue including hierarchically different levels; a weighted value random early detection (WRED) management unit capable of calculating the profile of the corresponding level by assigning different weighted values to the hierarchical queues according to each hierarchical queues; and a hierarchical scheduler capable of controlling traffic congestion by controlling packets in each level and using the profile calculated by the WRED management unit.;COPYRIGHT KIPO 2014;[Reference numerals] (100) Over traffic control unit;(110) Control packet asynchronous unit;(120) Hierarchical WRED profile calculating unit;(130) Hierarchical WRED setting unit;(20) Hierarchical scheduler;(200) Congestion avoiding unit;(210) Traffic controlling unit;(220) Congestion management unit;(AA) Level 1;(BB) Level 4;(CC) Level 1 WRED operation mode;(DD) Level 4 WRED operation mode;(EE) Queue level 4;(FF) Queue level 3;(GG) Queue level 2;(HH) Queue level 1;(II) Queue level 0
