On Packet Reordering in Time-Sensitive Networks [article]

Ehsan Mohammadpour, Jean-Yves Le Boudec
2021 arXiv   pre-print
Time-sensitive networks (IEEE TSN or IETF DetNet) may tolerate some packet reordering.  ...  There is so far no precise understanding of per-flow reordering metrics nor of the dimensioning of re-sequencing buffers in order to provide worst-case guarantees, as required in such networks.  ...  Time-sensitive networks may allow some limited amount of packet reordering.  ...

On Monitoring of End-to-End Packet Reordering over the Internet

Bin Ye, A.P. Jayasumana, N.M. Piratla
2006 International conference on Networking and Services (ICNS'06)  
End-to-end reordering of packets on Internet is investigated. Packet streams transferred over the Internet are used to analyze the long-term and shortterm trends in reordering.  ...  Reorder Entropy characterizes the reordering in a stream using a single value, reflecting the fraction of packets displaced as well as the magnitude displacements.  ...  ., reordering) during whole observation period for each network. One can see that packet reordering is prevalent in Net-1 and Net-5.  ...

Metrics for packet reordering—A comparative analysis

Nischal M. Piratla, Anura P. Jayasumana
2007 International Journal of Communication Systems  
Packet reordering is an inevitable phenomenon on the Internet.  ...  The attributes include the ability to capture reordering, sensitivity to lost and duplicate packets in reorder measurements, usefulness, simplicity, and evaluation complexity.  ...  In delay sensitive applications based on UDP, for example VoIP, an out-of-order packet that arrives after the elapse of playback time is treated as lost, thereby decreasing the perceived quality of voice  ...

Impact of acknowledgments on application performance in 4G LTE networks

2015 2015 International Conference on Computing, Networking and Communications (ICNC)  
4G LTE, the new cellular network standard, provides the capacity to support Quality of Service (QoS) for wireless multimedia applications.  ...  However, research has yet to examine the effects of the various LTE retransmission choices on QoS.  ...  The simulated UDP end-to-end packet delay includes both the delay on the core network to reach the 4G network and the time to traverse the LTE network itself.  ...

Reorder Density (RD): A Formal, Comprehensive Metric for Packet Reordering [chapter]

Nischal M. Piratla, Anura P. Jayasumana, Abhijit A. Bare
2005 Lecture Notes in Computer Science  
In delay sensitive applications based on UDP, e.g., IP telephony, an out-of-order packet that arrives after the elapse of playback time is treated as lost thereby decreasing the perceived quality of voice  ...  Moreover, the number of table entries in routers are growing exponentially [17] , which means that in spite of high-speed links in future, packets will spend more time within the network, i.e., a higher  ...  This indicates that the reorder response of a network, while dependent on the interpacket gap distribution in general, may not be highly sensitive to it.  ...

Slytherin: Dynamic, Network-assisted Prioritization of Tail Packets in Datacenter Networks [article]

Hamed Rezaei, Mojtaba Malekpourshahraki, Balajee Vamanan
2018 arXiv   pre-print
We make the key observation that long tails in the Flow Completion Times (FCT) of short flows result from packets that suffer congestion at more than one switch along their paths in the network.  ...  Our proposal, Slytherin, specifically targets packets that suffered from congestion at multiple points and prioritizes them in the network.  ...  Packet Reordering In this section we investigate the effect of expediting ECN marked packets on TCP packet reordering.  ...

Packet Reordering Metrics to Enable Performance Comparison in IP-Networks

Pedro Rodrigues Torres-Jr, Eduardo Parente Ribeiro
2020 Journal of Computer Networks and Communications  
In this paper, we present a scenario for testing and describe a methodology for conducting experiments to compare network paths with respect to unordered packets.  ...  On the other hand, more complete metrics are represented in a vectorial manner, making comparative analysis challenging.  ...  However, the use of any of these metrics alone is insufficient to completely characterise all aspects of packet reorder in a path on the network.  ...

Simulation-Based Comparisons of Solutions for TCP Packet Reordering in Wireless Networks

Daiqin Yang, Ka-Cheong Leung, Victor O. K. Li
2007 2007 IEEE Wireless Communications and Networking Conference  
First, we compare the performance, through computer simulations, of some solutions for TCP packet reordering in wireless networks.  ...  Thus, the problem of high channel error rates in wireless networks becomes the problem of packet reordering due to link-layer retransmissions.  ...  Packet reordering refers to the network behaviour where the relative order of some packets in the same flow is altered when these packets are transported in the network.  ...

Recovery of loss of packet in network using constant packet reordering

Sandeep Kumar Gonnade, Naresh Kumar Nagwani
2011 International Journal of Communication Networks and Security  
Packet reordering has does not effect on the performance of TCP-CPR.  ...  If acknowledgement are not received within the appropriate time then packet assume to loss because of the TCP-CPR does not depend on the duplicate acknowledgement.  ...  Most standard implementations of TCP perform poorly when packets are reordered. In existing TCP was based on the premise that packet loss is an indication of network congestion.  ...
