With the emergence of smartphones, data traÿc became the dominant application type in current mobile networks. This thesis deals with the comparison of the per-formance of di˙erent TCP congestion control algorithms when running in an LTE network. We developed an environment allowing for the simulation of the Linux im-plementation of di˙erent TCP variants and compared their performance in di˙erent scenarios. The results show that the loss-based variants manage to reach full link util-isation but create huge amount of delay whereas the delay-based mechanisms keep the delay under control but are not always able to fill the link.
