Method for voice/data transport over UDP/TCP/IP networks using an efficient buffer management

By a voice and data transmission method as UDP / TCP / IP network, based on the buffer management in the use of a buffer in, UDP / TCP / IP network in the edge router to control the flow of traffic, comprising: receiving a packet from a network; The received packet is for notifying the traffic congestion of a network determining whether a choke packet (Packet Choke); If the received packet is not a choke packet, classifying the received packet to a predetermined traffic class; A step of dividing the buffer logically assign different buffer areas of the buffer logically partitioned to correspond to the traffic classification on the received packet; And performing any one of an operation of the store for a predetermined time to the received packet discard with classification assigned to the traffic class and the buffer area, the method comprising: controlling the transfer of the received packet, and a. Thus, while constantly ensuring the proper bandwidth for real-time traffic demands, it is possible to prevent application data traffic based on the TCP that this situation does not occur at all allocated bandwidth.
