“…There are several ways to deliver such a signal. One common approach is to use the IP or TCP option to piggyback the explicit feedback on ACK packets [27]. However, in today's Internet, there are middle-boxes with the tendency of removing the TCP option from the TCP stream [28].…”

We propose XRC, an explicit rate control algorithm that overcomes the poor performance of commonly used TCP variants in cellular networks. XRC exploits explicit feedback from the radio access network that is aware of the physical, network and transport layer information of all UEs as well as resource distribution policies for users with different traffic characteristics. XRC co-exists fairly with other XRC and non-XRC flows at the wireless and non-wireless bottlenecks while it strictly controls queuing delay within a small threshold. We implement XRC in NS-3 and examine its performance across a range of network loads and dynamics. When competing with CUBIC at a wireless bottleneck, XRC achieves a Jain's fairness index of 99.7% while providing a 3x lower median queuing delay compared to when CUBIC competes with CUBIC in the same setup.

Tran et al [7] present a method to add functionality to the TCP kernel implementation using eBPF.

Networked systems and applications are often based on proprietary hardware/software components that manufacturers might not be willing to adapt or update if new requirements arise. We present mechanism interception, a novel approach to unobtrusively add or modify functionality to/of an existing networked system or application without touching any proprietary components. Behavioral changes are achieved by functionality-enhancing yet unobtrusive interceptors, i.e., components introduced between systems and their environments adding or updating mechanisms. We illustrate our approach by unobtrusively adding a vertical handover mechanism between Wi-Fi and LTE to a mobile end device without disconnecting TCP sessions. Our results indicate that mechanism interception is a compelling approach to achieve improved service quality and provide previously unavailable functionality.

TCP and TLS are among the essential protocols in today's Internet. TCP ensures reliable data delivery while TLS secures the data transfer. Although they are very often used together, they have been designed independently following the Internet layered model. This paper demonstrates the various benefits that a closer integration between TCP and TLS would bring.By leveraging the extensible TLS 1.3 records, we combine TCP and TLS into TCPLS to build modern transport services such as multiplexing, connection migration, stream steering, and bandwidth aggregation. These services do not modify the TCP wire format and are resistant to middleboxes. TCPLS offers a powerful API enabling applications to precisely express the required transport services, ranging from a single-path single-stream connection to a multistream connection over several network paths, enabling choices between aggregated bandwidth and head-of-line blocking avoidance.Compared to MPTCP, our TCPLS prototype offers more control to the application and can be easily deployed as an extension to user-space TLS libraries, while being implemented at a low cost. Measurements demonstrate that it offers higher performance than existing QUIC libraries with a super set of transport services. CCS CONCEPTS• Networks → Transport protocols; Network protocol design.
