RSS tcp - ip delayBenchmarking High Bandwidth-Delay Product Protocols
White Paper In the largest bandwidth-delay product environment the authors tested, PSockets achieved a maximum bandwidth of 875Mbps, while RBUDP and UDT were not far behind at 837Mbps and 840Mbps respectively, compared to 4.57Mbps for TCP. [11 Jul 2008]
Rate Based Congestion Control Over High Bandwidth/Delay Links
White Paper As the network bandwidth and delay increase, traditional dominant transfer protocols on the Internet like TCP have shown inefficiency and instability to many applications involved in huge amounts of data transfer. [11 Jul 2008]
AntiECN Marking: A Marking Scheme for High Bandwidth Delay Connections
White Paper This paper describes a simple scheme that uses feedback from underutilized high capacity links to allow a TCP connection to aggressively increase its sending rate. The paper shows through simulations that such a scheme allow TCP connections to... [11 Jul 2008]
Rate Allocation Under Network End-to-End Quality-of-Service Requirements
White Paper This paper addresses the problem of allocating transmission rates to a set of network sessions with end-to-end bandwidth and delay requirements. It gives a unified convex programming formulation that captures both average and probabilistic delay... [10 Jul 2008]
Investigation of Ethernet Switches Behavior in Presence of Contending Flows at Very High-Speed
White Paper This paper examines the interactions between high speed Ethernet switches and TCP in high bandwidth delay product networks. Then the impact of these switches behaviors is studied on TCP protocols in Long and Fast Networks (LFNs). [08 Jul 2008]
Achieving High Throughput in Low Multiplexed, High Bandwidth, High Delay Environments
White Paper In the scheme, a TCP source reacts differently on receiving an ECN than it does on inferring a packet loss in terms of congestion window update. Coupled with an AQM scheme such as RED, TCP sources achieve high utilization at a bottleneck router... [08 Jul 2008]
SABUL: A Transport Protocol for Grid Computing
White Paper This paper describes SABUL, an application-level data transfer protocol for data-intensive applications over high bandwidth-delay product networks. It uses UDP to transfer data and TCP to return control messages. [10 Apr 2008]
UDT: An Application Level Transport Protocol for Grid Computing
White Paper Data-intensive applications over high bandwidth delay product (BDP) networks, such as computational grids, need new transport protocols to support them. As network bandwidth and delays increase, TCP becomes inefficient. [10 Apr 2008]
Impact of TCP-Like Congestion Control on the Throughput of Multicast Groups
White Paper This paper studies the impact of randomness (i.e.variation of queuing delay due to cross traffic) on the performance of a (one-to-many) multicast session in the presence of a "TCP-like" congestion control mechanism. [04 Apr 2008]
Lossy Bulk Synchronous Parallel Processing Model for Very Large Scale Grids
White Paper However, TCP does not perform well in a high bandwidth and high delay network environment. Many grid programming platforms use TCP due to its reliability, usually with some optimizations to reduce its costs. [03 Mar 2008]
The Role of Buffer Management in Controlling the Effects of Congestion over 10 GbE Links
White Paper This white paper describes the rationale for providing switch/routers with port buffers that are scaled to the expected delay-bandwidth product (DBP). DBP-sized buffers, together with RED congestion avoidance, can be used to optimize the... [07 Feb 2008]
Impact of Round Trip Delay Self-Similarity on TCP Performance
White Paper Recent measurement showed that self-similar nature is found not only in network traffic volume but also round trip packet delay. First, the paper discusses the origin of the packet delay self-similarity. [14 Jan 2008]
Avoiding Spurious TCP Timeouts in Wireless Networks by Delay Injection
White Paper While TCP can adapt to small fluctuations in the delay between the sender and the receiver, adverse affects (most importantly spurious timeouts) have been observed under large delay variability. Then it investigates a new methodology for avoiding... [14 Jan 2008]
Queue Delay Estimation and Its Application to TCP Vegas
White Paper It also proposes an estimation algorithm for the marking queue delay in TCP data traffic by using the Kalman filter. With this, the marking queue delay is defined. The modified Vegas algorithm supplements the shortcomings of Vegas such as... [14 Jan 2008]
Global Stability Analysis of a TCP/AQM Protocol for Arbitrary Networks With Delay
White Paper This paper investigates global stability of Fast AQM Scalable TCP (FAST), a network congestion control scheme for the Internet modelled by a nonlinear delay differential equation with heterogeneous delays. [14 Jan 2008]
