| Summary: | 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. === På grund av utvecklingen av smartphones blev data den största källan av traffik i aktuella mobilnätverk. Den här uppsatsen handlar om jämförelsen av utförandet av olika TCP Congestion Control Algorithms när de används i LTE nätverk. Vi utveklade ett system som kan användas för att simulera Linux implementeringar av olika TCP versioner och jämföra deras utförande i olika situationer. |
