Abstract

In this paper we verified that the window based TCP performance of throughput can be improved by the traffic connection efficiency. and have studied the performance of traffic congestion control that is controlling transmission rate. In wireless network, the bidirectional node is run by estimating the usage rate of link of error control idle and the throughput is shown by transmitting segments. The throughput rate shows almost no delay due to the bidirectional traffic connection efficiency up to the allowable point as increasing the transport rate by the critical value, depending on the size of end-to-end node queue of the increase of transport rate. This paper reports the performance improvement as the number of feedback connection traffic congestion control increases because of the increase of the number of asynchronous transport TCP connections.

TCP 전송제어 프로토콜은 원도우 기반에서 트래픽의 연결 효율성으로 인해 성능 처리율이 향상됨을 입증하고, 전송률을 제어하는 혼잡제어 성능을 연구한다. 무선네트워크에서 에러제어 휴지의 링크 이용율을 산출하여 양방향 노드를 동작시키고, 세그먼트를 전송하여 전송률을 나타낸다. 연결 혼잡 발생을 하지 않은 ACK승인 압축을 처리하여, 임계값에 의해 전송률을 증가시켜 종단 간 노드 큐의 크기에 따라 허용될 수 있는 부분까지 양방향 트래픽의 대역폭 연결효율성에 의해 지연이 거의 없는 처리율이 된다. 본 논문은 트래픽이 존재하는 비동기 전송 TCP 연결 개수가 늘어남에 따라 피드백 연결 혼잡제어 수가 증가하여 성능이 개선됨을 나타낸다.
