Network performance test ttcp/nttcp/nuttcp/iperf versionsttcp was one of the first TCP throughput testing tools ever written. It was created by Mike Muuss at BRL to compare the performance of TCP stacks by U.C. Berkeley and BBN to help DARPA decide which version to place in the first BSD Unix release (Berkeley won). The name stands for "Test TCP", but it also supports UDP testing. Many variations have since been created.. 2005. 9. 20. TCP/IP 동영상 해커스랩 2002. 12. 4. 이전 1 2 3 다음 728x90
