Statistical Sharing and Traffic Shaping: Any Contradiction? [chapter]

Yee-Hsiang Chang
1995 IFIP Advances in Information and Communication Technology  
One example is in Figure 1 , the multiplexing of traffic A and B reduces the overall variance. If there are more traffic multiplexing together, the variance goes down further.  ...  That is, the stable state in the network utilization is achieved when the number of users is large, in which case each individual traffic balance its burstiness traffic with others.  ...  The performance model (G/D/1) Here, a simple model is used to show the performance of a network with traffic shaping.  ...

2009 IEEE/ACM Transactions on Networking  
In particular, the traffic reporting enables a rich description of the diversity of microcongestion behavior, without model assumptions, and at achievable computational cost.  ...  This enables a comprehensive examination of congestion and delay from three points of view: the understanding of origins, measurement, and reporting.

Bandwidth Estimation for Best-Effort Internet Traffic

Jin Cao, William S. Cleveland, Don X. Sun
2004 Statistical Science  
This model is built and validated using queueing theory and extensive empirical study; it is valid for traffic with 64 host pair connections or more, which is about 1 megabit/sec of traffic.  ...  Packets can queue up and are dropped if the queue size (bits) is bigger than the size of the buffer (bits) for the queue.  ...  In other studies, queueing simulations of both live and altered live traffic are used to study the effect of dependence properties and multiplexing on performance using the average queue length as the  ...

Split, Send, Reassemble: A Formal Specification of a CAN Bus Protocol Stack

Rob van Glabbeek, Peter Höfner
2017 Electronic Proceedings in Theoretical Computer Science  
We present a formal model for a fragmentation and a reassembly protocol running on top of the standardised CAN bus, which is widely used in automotive and aerospace applications.  ...  Although the CAN bus comes with an in-built mechanism for prioritisation, we argue that this is not sufficient and provide another protocol to overcome this shortcoming.  ...  The input queue of the multiplexer, on the other hand, has a maximal length.  ...

Optical Packet Buffers for Backbone Internet Routers

Neda Beheshti, Emily Burmeister, Yashar Ganjali, John E. Bowers, Daniel J. Blumenthal, Nick McKeown
2010 IEEE/ACM Transactions on Networking  
With the combination of these two results, we conclude that future Internet routers could use optical buffers. Index Terms-Buffer size, integrated optical memory, packet switching, TCP.  ...  Building optical buffers for routers is daunting: Today's electronic routers often hold millions of packets, which is well beyond the capabilities of optical technology.  ...  Here, we want to know whether we can set the buffer size as small with short packets and yet achieve the same performance as what we achieve with long packets.  ...
