Abstract

With rapid development of network communications, the performance requirements of applications are getting more differentiated. Many applications like high-definition video transfer require high throughput but do tolerate occasional packet losses. Traditional generic transport protocols however, only provide inflexible data transfer guarantees (TCP (Transmission Control Protocol) offers full reliability guarantees and UDP (User Datagram Protocol) offers no guarantees). Moreover, TCP pays a significant price to ensure a full reliability guarantee over lossy wireless communications environment like 5G millimeter wave (mmWave) communications. While existing, “partially” reliable transport protocols are either specifically designed for certain applications or need router’s support. In this paper, we design a new generic Differentiated Reliable Transport Protocol (DRTP), aiming to provide a differentiated and deterministic reliability guarantee for upper layer applications while maximizing the throughput under the constraint of guaranteeing a required reliability of data transfer. DRTP is a generic and pure end-to-end partially reliable transport protocol, and as such is easy to deploy regardless of the application in use and with no need for router’s support. The performance of DRTP is evaluated under various network conditions using extensive NS-3 (Network Simulator) simulations and practical experiments over the mmWave communications environment. The results show much higher throughput compared to typical transport protocols while guaranteeing the required transfer reliability.

DRTP：通用的差异化可靠传输协议

随着网络通信的快速发展，应用对性能的要求也越来越多样化。许多应用（如高清视频传输）要求高吞吐量，但又能容忍偶尔的数据包丢失。然而，传统的通用传输协议只能提供不灵活的数据传输保证（TCP（传输控制协议）提供完全的可靠性保证，UDP（用户数据报协议）不提供任何保证）。此外，在 5G 毫米波（mmWave）通信等有损无线通信环境中，TCP 要确保完全的可靠性保证需要付出巨大的代价。现有的 "部分 "可靠传输协议要么是专门为某些应用设计的，要么需要路由器的支持。在本文中，我们设计了一种新的通用差异化可靠传输协议（DRTP），旨在为上层应用提供差异化和确定性的可靠性保证，同时在保证所需数据传输可靠性的约束条件下最大化吞吐量。DRTP 是一种通用的、纯粹的端到端部分可靠传输协议，因此易于部署，无需路由器的支持，也无需考虑使用中的应用程序。在毫米波通信环境下，通过大量的 NS-3（网络模拟器）模拟和实际实验，对 DRTP 在各种网络条件下的性能进行了评估。结果表明，与典型的传输协议相比，DRTP 的吞吐量要高得多，同时还能保证所需的传输可靠性。

期刊介绍： Computer and Communications networks are key infrastructures of the information society with high socio-economic value as they contribute to the correct operations of many critical services (from healthcare to finance and transportation). Internet is the core of today''s computer-communication infrastructures. This has transformed the Internet, from a robust network for data transfer between computers, to a global, content-rich, communication and information system where contents are increasingly generated by the users, and distributed according to human social relations. Next-generation network technologies, architectures and protocols are therefore required to overcome the limitations of the legacy Internet and add new capabilities and services. The future Internet should be ubiquitous, secure, resilient, and closer to human communication paradigms. Computer Communications is a peer-reviewed international journal that publishes high-quality scientific articles (both theory and practice) and survey papers covering all aspects of future computer communication networks (on all layers, except the physical layer), with a special attention to the evolution of the Internet architecture, protocols, services, and applications.
