This paper provides an authoritative knowledge of through-router packet delays and
therefore a better understanding of data network performance. Thanks to a unique …

We measure and analyze the single-hop packet delay through operational routers in a
backbone IP network. First we present our delay measurements through a single router …

Using an authoritative data set from a fully instrumented router at the edge of a core network,
packet delays through an access link are studied in detail. Three different root causes of …

Traditionally, it had been assumed that the efficiency requirements of TCP dictate that the
buffer size at the router must be of the order of the bandwidth-delay (C× RTT) product …

During the past four years, several papers have proposed rules for sizing buffers in Internet
core routers. Appenzeller et al. suggest that a link needs a buffer of size O (C/√ N), where C …

As the Internet role changes from the experimental environment to the social infrastructure,
end-to-end quality for data transfer of various types of traffic has been required as well as its …

This paper concerns the modelling of Internet packet traffic. In previous work we showed that
a Bartlett–Lewis point process, as a model of packet arrivals on backbone links, enjoys …

We measure and analyze the single-hop packet delay through operational routers in the
Sprint Internet protocol (IP) backbone network. After presenting our delay measurements …

Measurement of the main contributions to the single-hop delay introduced by an open-
source router is dealt with. A new method is proposed, which is capable of distinguishing the …

The queueing delay faced by a packet is arguably the largest source of uncertainty during its
journey. It therefore seems crucial that we understand how big the buffers should be in …
