Zero Round-Trip Time for the Extended Access Control Protocol [chapter]

Jacqueline Brendel, Marc Fischlin
2017 Lecture Notes in Computer Science  
Here we discuss how to enhance the EAC protocol by a so-called zero-round trip time (0RTT) mode.  ...  Such a mode is called zero round-trip time (0RTT). The first proposal for a 0RTT-supporting protocol came from Google with its QUIC protocol [19] .  ...  Acknowledgements We thank the anonymous reviewers for valuable comments.  ...

Compound TCP+: A Solution for Compound TCP Unfairness in Wireless LAN

Hiroki Oda, Hiroyuki Hisamatsu, Hiroshi Noborio
2013 Journal of Information Processing  
However, in wireless LAN, the media access control used causes unfairness in the throughput among TCP connections.  ...  In high-speed and long-distance networks, TCP NewReno, the most popular version of Transmission Control Protocol (TCP), cannot achieve sufficient throughput owing to the inherent nature of the congestion  ...  Many packets are accumulated at the access point buffer, and the round-trip time increases.  ...

Active Window Management: Performance Assessment through an Extensive Comparison with XCP [chapter]

M. Barbera, M. Gerla, A. Lombardo, C. Panarello, M. Sanadidi, G. Schembra
2008 Lecture Notes in Computer Science  
The most authoritative solution in this context seems to be the eXplicit Control Protocol (XCP) which achieves high performance but requires changes in both network routers and hosts which make it difficult  ...  The most efficient approaches defined so far to address performance degradations in end-to-end congestion control exploit the flow control mechanism to improve end-to-end performance.  ...  In addition, since the round-trip time is function of the bottleneck queuing time, small oscillations around the average queue length make variance of the round-trip time small as well, implying small  ...

Design of SIP transformation server for efficient media negotiation

Sangheon Pack, Eun Kyoung Paik, Yanghee Choi, Petros Mouchtaris
2001 Voice Over IP (VoIP) Technology  
It takes only 1.5 round trip times to negotiate two different media types while the standard media negotiation mechanis m takes 2.5 round trip times.  ...  The extra processing time in message handling is negligible in comparison to the reduced round trip time.  ...  The round trip times for the session setup become from 2.5 round trip times to 1.5 round trip times.  ...

A virtual loss-load congestion control strategy for high speed networks

Narayanan Prithviraj, Carey L. Williamson
1996 Computer communication review  
Second, the authors incorporate the round-trip delay and get more general window control schemes. Third, the ECN is used as congestion indictor instead of packet losses.  ...  Abstract: The authors study a single node with multiple flows based on a deterministic fluid model where the multiple flows have different round-trip delays.  ...  Then, we propose an experimental congestion avoidance mechanism, which relies on a fine-grained RTT estimation and coordinates the upward and backward window adjustments, to improve TCP smoothness for  ...

Congestion Control for Small Buffer High Speed Networks

Y. Gu, D. Towsley, C. V. Hollot, H. Zhang
2007 IEEE INFOCOM 2007 - 26th IEEE International Conference on Computer Communications  
Unfortunately, as we show in this paper, as workload requirements grow and connection bandwidths increase, the interaction between the congestion control protocol and small buffer routers produce link  ...  In this paper we present a new congestion controller that avoids this problem by allowing a TCP connection to achieve arbitrarily large bandwidths without demanding the loss probability go to zero.  ...  Any Opinions, findings and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect those of the National Science Foundation.  ...

A MAC protocol for efficient multiplexing QoS-sensitive and best-effort traffic in dynamically configurable WDM rings

Helen-Catherine Leligou, John D Angelopoulos, Charalambos Linardakis, Alexandros Stavdas
2004 Computer Networks  
The performance of the proposed mechanism is evaluated via simulations demonstrating access delay below the round trip time for high priority traffic and good overall system efficiency by filling any spare  ...  In contrast, best effort traffic is using only any bandwidth left over by the high QoS traffic, thus exploiting the elastic behaviour of besteffort traffic and its closed loop control.  ...  Acknowledgements The work presented in this paper was partially funded by the EU project IST-1999-11742 ''DA-VID''.  ...
