“…Two metrics related to bandwidth are extensively investigated in the literature, the maximum possible data rate called capacity and the maximum available data rate called available bandwidth [50]. Packet dispersion techniques [18], [17], [52], [34], [38] are widely used to measure bottleneck link capacity. Available bandwidth measurement techniques are outlined in [30], [31], [51], [54], [27], [16], [42], [41], [6], [2], [57], [56].…”

“…On a multiple-hop path, maintaining a zero-dispersion gap before creating a pre-defined dispersion gap in the compound probe at the router under test is feasible with the proper sizing of P t , P h , and P r . However, heterogenous link-capacities over an end-to-end path can impact the sizing of the compound probe [25]. For example, any dispersion (zero and non-zero) in a pair of packets on a router is dependent on the packet-size ratio and the link-capacity ratio between the input and output links [25]- [27].…”

For example, any dispersion (zero and non-zero) in a pair of packets on a router is dependent on the packet-size ratio and the link-capacity ratio between the input and output links [25]- [27]. This infers that we need an a-priori knowledge of the link capacities over an end-to-end path for determining the required sizing of the packets in the compound probe.…”

Determining the qualitative States-of-the-Internet requires an accurate knowledge of queueing delay over an end-to-end path. However, the measurement of queueing delay in a large network is still considered a complex and open problem. Existing schemes that measure queueing delay compensate for this complexity using a high infrastructural support and administrative access to the path under test even though their feasibility and accuracy on the Internet are low. In this article, we propose an active scheme, called COMPRESS: COMpound Probe compRESSion, to measure queueing delay on all routers over an end-to-end path. The proposed scheme performs per-hop measurement using UDP-based probing packets. It is both simple and self-sufficient in comparison to the existing schemes. We have implemented the proposed scheme in a simulation environment to present a controlled performance evaluation under different levels (e.g., light, moderate, and heavy) and types (e.g., symmetric and asymmetric) of queueing delays over single-and multiple-hop paths. Our simulation results show that the scheme is sensitive to the induced queueing delays and consistently produces a high measurement accuracy. Overall, the scheme has an average measurement error of around 20% or below over the simulated paths.
