Satellite link characteristics cause reduced performance in TCP data transfers. This paper presents SaTPEP, a TCP Performance Enhancing Proxy which attempts to improve TCP performance by performing connection splitting. SaTPEP monitors the satellite link utilization, and assigns to connections window values that reflect the available bandwidth. Loss recovery is based on Negative Acknowledgements. The performance of SaTPEP is investigated in terms of goodput and fairness, through a series of simulation experiments. Results obtained in these experiments, show significant performance improvement in presence of available bandwidth and at high error rates.
