An important class of datacenter applications, called Online DataIntensive (OLDI) applications, includes Web search, online retail, and advertisement. To achieve good user experience, OLDI applications operate under soft-real-time constraints (e.g., 300 ms latency) which imply deadlines for network communication within the applications. Further, OLDI applications typically employ tree-based algorithms which, in the common case, result in bursts of children-to-parent traffic with tight deadlines. Recent work on datacenter network protocols is either deadline-agnostic (DCTCP) or is deadline-aware (D 3 ) but suffers under bursts due to race conditions. Further, D 3 has the practical drawbacks of requiring changes to the switch hardware and not being able to coexist with legacy TCP.We propose Deadline-Aware Datacenter TCP (D 2 TCP), a novel transport protocol, which handles bursts, is deadline-aware, and is readily deployable. In designing D 2 TCP, we make two contributions: (1) D 2 TCP uses a distributed and reactive approach for bandwidth allocation which fundamentally enables D 2 TCP's properties. (2) D 2 TCP employs a novel congestion avoidance algorithm, which uses ECN feedback and deadlines to modulate the congestion window via a gamma-correction function. Using a small-scale implementation and at-scale simulations, we show that D 2 TCP reduces the fraction of missed deadlines compared to DCTCP and D 3 by 75% and 50%, respectively.

Widely implemented topology in Internet is Heterogeneous networks which are a combination of wired and wireless networks. Due to high bandwidth availability at wired links and high delayed products at wireless links, bottleneck situation is generated at Access Point and it has to face severe Congestion consequences. Some of the most known and recent protocols developed to provide faster and lighter congestion control are TCP (Transmission Control Protocol) and the Rate Control Protocol (RCP). This paper provides performance comparison of TCP, RCP+ and our proposed algorithm RCP++ in hybrid network.

“…Approaches such as VCP [31], MLCP [32], BMCC [33], XCP [13], RCP [34], and rate feedback in Quick-Start [12] are based on intermediate routers providing more extensive feedback, but more importantly are not meant to be submissive to other flows.…”

Abstract. Delay-insensitive applications, such as P2P file sharing, generate substantial amounts of traffic and compete with other applications on an equal footing when using TCP. Further, to optimize throughput, such applications typically open multiple connections. This results in unfair and potentially poor service for applications that have stringent performance objectives (including sensitivity to delay and loss). In this paper, we propose NF-TCP, a TCP variant for P2P and similar delay-insensitive applications that can afford to have communication in the "background". NF-TCP aims to be submissive to delay-sensitive applications under congestion. A major component of NF-TCP is to integrate measurement as an integral component of the congestion control framework. This enables the transport to exploit available bandwidth, so that it can aggressively utilize spare capacity.We implemented NF-TCP on Linux and ns-2. Our evaluations of the NF-TCP Linux implementation on ns-2 show that NF-TCP outperforms other network friendly approaches (e.g., LEDBAT, TCP-LP and RAPID). NF-TCP achieves high utilization, fair bandwidth allocation among NF-TCP flows and maintains a small average queue. Our evaluations further demonstrate that with NF-TCP, the available bandwidth can be efficiently utilized.
