Abstract
In this paper, the performance evaluation of TCP New Reno over satellite DVB-RCS2 links with random access is analyzed. Based on the satellite system consisting of a large number of source-destination TCP New Reno pairs, a Markov chain model for a TCP connection is conducted. According to the principles of TCP New Reno, two one-step transition probabilities for the value of congestion window in different data transmission phases (e.g. the slow start phase and congestion avoidance phase) are proposed. In order to analysis the throughput of a TCP connection, according to the packets lost events, three conditions (no packet lost, packets lost in the congestion avoidance phase, and packets lost in the slow start phase), are theoretically analyzed. We analytically derive the upper and lower throughput bounds, simulations and analysis are integrated together to indicate the effective ness and correctness of theoretical analysis. Moreover, we can clearly determine which factor plays role for the performance of TCP New Reno. The analysis not only includes the main algorithms of TCP protocol, but also is developed for general random access. Therefore, the Markov model and the theoretical analysis can be applied to many erasure channel, and the conclusions are extremely critical for the research of improving TCP performance over links with random access.
