Due to rapid increasing in complexity of Internet, quantifying the performance of protocol helps in assessing the application behavior with respect to network performance. TCP is an important protocol that is used by some important applications on Internet such as HTTP, FTP and soon. To analyze TCP, Round trip times is one of the metric used. As it is a internal metric of TCP used to find the retransmission timeout of sent packet. Round trip times means measuring elapsed time between the sent packet and recieving its acknowledgment that covers the sequence number of the sent packet(i.e., from source to destination and vice-a-versa). Round trip times is a metric that is recognised by IETF as Quality of Service parameter. We design a tool here that will calculate the round trip times for each stream. This round trip times helps us to understand the protocol behavior. In this document, we discuss the design, implementation issues carried out while developing the tool. This tool is capable of reading offline as well as online streams and helps us to analyze the statistics obtained from collected round trip times of each stream. === 91-40-24023214
