Insights into incremental quantile estimation methodology

Identification of challenges in network quality of service monitoring

Proposed approach for assessing loss and delay distributions

Abstract

Our comments are in two parts. First, we make some observations regarding the methodology in Chambers et al. [arXiv:0708.0302]. Second, we briefly describe another interesting network monitoring problem that arises in the context of assessing quality of service, such as loss rates and delay distributions, in packet-switched networks.
