Abstract

As discussed in Chaps. 1 and 3, clients performing synchronized reads across an increasing number of servers in high bandwidth, low latency data center environments, observe TCP’s throughput drop by one or two orders of magnitude below their link capacity. Labeled Incast, this pathological behavior of TCP is endured by a growing number of data center applications and services. Hence, a feasible solution that addresses the Incast problem is urgently needed. In this chapter, we provide a broad overview of existing Incast solutions followed by detailed description of our proposed techniques that are designed to address the Incast problem at the Transport Layer [1].
