快速用户数据报协议互联网连接(QUIC)1通过解决许多传输层和应用层问题来提高网络流量性能。QUIC提供了HTTP/2的关键优势，例如减少了连接建立延迟、改进了拥塞控制、前向纠错和连接迁移。然而，QUIC有三个局限性：(1)在高带宽和大流量条件下性能不佳；(2)存在一些安全问题；(3)它实现了静态转发纠错(FEC)异或“组”机制，在变化的网络条件下性能不佳，影响了带宽的利用率。软件定义网络(SDN)本质上是集中式的，可提供网络的全局视图。在与QuIC集成时，SDN提高了资源利用率和网络安全性，如我们在本文中所展示的。我们提出了一种SDN增强的QuIC，它在传输大量数据时实现了更高的带宽利用率和更高的安全性。
Quick User Datagram Protocol Internet Connection (QUIC) 1 boosts web traffic performance by solving a number of transport-layer and application-layer problems. QUIC provides key advantages to HTTP/2 such as reduced connection establishment latency, improved congestion control, forward error correction, and connection migration. However, QUIC suffers from three limitations: (1) it performs poorly under high bandwidth and heavy traffic conditions, (2) it suffers from some security issues, (3) it implements static Forwarding Error Correction (FEC) XOR "group" mechanism, which performs poorly under variable network conditions, influencing the utilized bandwidth. Software Defined Networking (SDN), being centralized by nature, provides a global view of the network. When integrated with QUIC, SDN improves resource utilization and network security as we show in this paper. We propose an SDN-enhanced QUIC that achieves improved security at higher bandwidth utilization when transferring large amounts of data.
