Abstract
The internet is an integral part of our daily life and business. In recent years, internet access has moved from wired connections to a substantial amount of wireless communication. Although the link layer is evolving, higher network layers do not. Hence, most wireless communication is handled by standard TCP/IP stacks, even though TCP does not perform to its best on wireless links. Additionally, TCP offers partially redundant services to the link layer, as it is possible to ensure reliability and in-order-delivery in managed wireless technologies (such as LTE). These problems lead to underutilized wireless links and not optimal user experience. In this paper, we present UDP++, an adaptable transport layer protocol for managed wireless links. UDP++ offers a feature set to achieve TCP-like transport layer communication. Thereby any feature is optional and configurable at runtime, to ensure a perfect match between application requirements and the communication link, without unnecessary services. This results in better quality of service outcomes, reduced overhead traffic, and less CPU utilization. Our evaluation show around 45 less end-to-end latency and around 30 less overhead traffic compared to the de-facto standard TCP.
