TLDR
This article presents a comprehensive survey of existing transport layer solutions proposed for mitigating the problems of TCP in data center networks.Abstract:
In recent years, data centers play an important role in academia and industry for supporting various services and applications. Compared with other IP networks, data center networks have some special features such as many-to-one communication pattern with high bandwidth, low latency, auto-scaling, shallow buffered switches and multi-rooted tree topology. Owing to these special features of data center networks, traditional TCP suffers from severe performance degradation. For improving the performance of TCP in data center networks, various solutions have been proposed in recent years. This article presents a comprehensive survey of existing transport layer solutions proposed for mitigating the problems of TCP in data center networks. The objective of this article is threefold: to discuss about the issues of TCP in data center networks; to introduce various transport layer solutions and finally to compare and discuss the challenges of existing solutions proposed for improving the performance of TCP in data center networks.read more

Tuning the Aggressive TCP Behavior for Highly Concurrent HTTP Connections in Intra-Datacenter
TL;DR: This first extensive study to investigate the root cause of performance degradation of highly concurrent HTTP connections in data center network presents the design and implementation of TCP-TRIM, which employs probe packets to smooth the aggressive increase of congestion window in persistent TCP connection and leverages congestion detection and control at end-host to limit the growth of switch queue length under highly concurrent TCP connections.

Data center TCP (DCTCP)
Mohammad Alizadeh,Albert Greenberg,David A. Maltz,Jitendra Padhye,Parveen Patel,Balaji Prabhakar,Sudipta Sengupta,Murari Sridharan +7 more
TL;DR: DCTCP enables the applications to handle 10X the current background traffic, without impacting foreground traffic, thus largely eliminating incast problems, and delivers the same or better throughput than TCP, while using 90% less buffer space.
