“… Copies of memory-to-memory (M2M) are obtained for sending large data in the cost of processor bus BW, CPU cycle, latency and memory controller BW. In addition, remote direct memory access (RDMA) is getting wide acceptance as proficient 0-copy transfer protocol [17], [18]. However, an efficient deployment of RDMA is complex on byte stream abstraction.…”

Abstract-With developments of real-time applications into data centers, the need for alternatives of the standard TCP protocol has been prime demand in several applications of data centers. The several alternatives of TCP protocol has been proposed but SCTP has edge due to its several well-built characteristics that make it capable to work efficiently. In this paper, we examine the features of SCTP into data centers like Multi-streaming and Multi-Homing over the features of TCP protocol.In this paper, our objective is to introduce internal problems of data centers. Robust transport protocol reduces the problems with some extend. Focusing the problems of data centers, we also examine weakness of highly deployed standard TCP, and evaluate the performance of SCTP in context of faster communication for data centers. We also discover some weaknesses and shortcomings of SCTP into data centers and try to propose some ways to avoid them by maintaining SCTP native features. To validate strength and weakness of TCP and SCTP, we use ns2 for simulation in context of data center. On basis of findings, we highlight major strength of SCTP. At the end, we Implement finer grain TCP locking mechanisms for larger messages.

“…We identified three factors that may contribute to increase the level of contention: (1) the large congestion window increases the contention among the TCP data packets in the forward path Chen et al, 2003;Kim et al, 2005;Triantafyllidou et al, 2009) (2) generating ACK for every arrived packet will increase the contention between data and ACK packets in the forward and return path (Singh and Kankipati, 2004;Oliveira and Braun, 2007;Chen et al, 2008) and (3) hidden and exposed terminals (Chen et al, 2008;Cai et al, 2008). These factors cause an excessive number of medium accesses (Cai et al, 2008;Kim et al, 2006) that increases the level of contention.…”

Transmission Control Protocol (TCP) is a fundamental protocol in the TCP/IP Protocol Suite.TCP was well designed and optimized to work over wired networks where most packet loss occurs due to network congestion. In theory, TCP should not care whether it is running over wired networks, WLANs, or Mobile Ad hoc Networks (MANETs). In practice, it does matter because most TCP deployments have been carefully designed based on the assumption that congestion is the main factor of network instability. However, MANETs have other dominating factors that cause network instability. Forgetting the impact of these factors violates some design principles of TCP congestion control and open questions for future research to address. This study aims to introduce a model that shows the impact of MANET factors on TCP congestion control. To achieve this aim, Design Research Methodology (DRM) proposed by BLESSING was used as a guide to present this model. The proposed model describes the existing situation of TCP congestion control. Furthermore, it points to the factors that are most suitable to be addressed by researchers in order to improve TCP performance. This research proposes a novel model to present the impact of MANET factors on TCP congestion control. The model is expected to serve as a benchmark for any intended improvement and enhancement of TCP congestion control over MANET.

Abstract-In explicit or delay-driven congestion control, a common objective is to sustain high throughput without long queues and large losses at the bottleneck link of the network path. Congestion control protocols strive to achieve this goal by transmitting smoothly in the steady state. The discovery of the appropriate steady-state transmission rates is a challenging task in itself and typically introduces additional queuing and losses. Seeking insights into the steady-state profiles of queuing and loss achievable by real protocols, this paper presents an AIST (Asynchronous arrivals with Ideally Smooth Transmission) model that abstracts away transient queuing and losses related to discovering the path capacity and redistributing it fairly among the packet flows on the bottleneck link. In AIST, the flows arrive asynchronously but transmit their packets at the same constant rate in the steady state. For the link with an overprovisioned buffer, our queuing-theoretic analysis and simulations for different smooth distributions of packet interarrival times agree that queuing under AIST with the target utilization of 1 is on the order of the square root of N , where N is the number of flows. With small buffers, our simulations of AIST show an ability to provide bounded loss rates regardless of the number of flows.
