交互式实时的通信中的纠删编码和拥塞控制
Erasure Coding and Congestion Control for Interactive Real-Time Communication
摘要：
在Internet上使用实时的【形】应用是一个具有挑战性的问题，QoS时代试图通过提出DiffServ架构来解决。今天，互联网提供的唯一服务仍然是尽力而为。因此，多媒体应用通常在提供可变发送速率的传输层之上执行。显然，这种可变发送速率对于具有强延迟约束的这些应用是一个问题。在不能使用重传来确保可靠性的实时的【形】上下文中，视频质量受到任何分组丢失的影响。在这份立场文件中，我们讨论了这个问题，并激发为什么我们要在多媒体拥塞控制协议（如TFRC）中提出某类纠删编码方案。
英文摘要：
The use of real-time applications over the Internet is a challenging problem that the QoS epoch attempted to solve by proposing the DiffServ architecture. Today, the only existing service provided by the Internet is still best-effort. As a result, multimedia applications often perform on top of a transport layer that provides a variable sending rate. In an obvious manner, this variable sending rate is an issue for these applications with strong delay constraint. In a real-time context where retransmission can not be used to ensure reliability, video quality suffers from any packet losses. In this position paper, we discuss this problem and motivate why we want to bring out a certain class of erasure coding scheme inside multimedia congestion control protocols such as TFRC.
