Abstract
Many of today's Internet applications such as mobile web browsing and live video streaming are delay and throughput sensitive. In face of the great success of cellular networking, especially with the advent of the high-speed LTE access tech-nology, it is noteworthy that there is little consensus on the performance experienced by applications running over cellular networks. In this paper we present application-level performance results measured in a major commercial LTE network. We replicate measurements in a wired access network to provide a reference for the wireless results. We investigate the performance of common web application scenarios over LTE. In addition, we deploy controlled measurement nodes to discover transparent middleboxes in the LTE network. The introduction of middle-boxes to LTE results in a faster connection establishment on the client side and notable performance gain for HTTP. However, this improvement comes at the price of ambiguity as some middlebox operations may introduce unnecessary timeouts. Further, we pinpoint LTE specific delays that arise from network signalling, energy saving algorithms and Hybrid Automatic Repeat reQuest (HARQ). Our analysis provides insights into the interaction between transport protocols and LTE.
