论文摘要
尽管历史悠久而成功，但TCP还是现代数据中心的运输协议差。 TCP的每一个重要元素，从其流取向到其对订购数据包交付的期望，对于数据中心来说都是错误的。现在是时候认识到TCP的问题太根本了，无法解决；利用现代网络的全部性能潜力的唯一方法是将新的运输协议引入数据中心。 HOMA证明，可以创建一个避免TCP所有问题的运输协议。尽管HOMA与TCP不兼容API，但应该通过将其与RPC框架集成到广泛的用法中。
In spite of its long and successful history, TCP is a poor transport protocol for modern datacenters. Every significant element of TCP, from its stream orientation to its expectation of in-order packet delivery, is wrong for the datacenter. It is time to recognize that TCP's problems are too fundamental and interrelated to be fixed; the only way to harness the full performance potential of modern networks is to introduce a new transport protocol into the datacenter. Homa demonstrates that it is possible to create a transport protocol that avoids all of TCP's problems. Although Homa is not API-compatible with TCP, it should be possible to bring it into widespread usage by integrating it with RPC frameworks.
