“…Many of these metrics are completely described by the Internet Protocol Performance Metrics (IPPM) working group of the IETF. Concretely, the delay measurements in one way [4] and round-trip [5] are really important for this work, as these methodologies are grounded standards and good examples of how to measure the latency.…”

Nowadays, the demand of Over-The-Top (OTT) services such as multimedia streaming, web services or social networking is rapidly increasing. Consequently, there is a wide interest in studying the quality of these services so that Internet Service Providers (ISP) can deliver the best experience to their clients.For this purpose, we present FlexiTop, a flexible and scalable system to actively monitor these OTT services, which allows an operator to obtain metrics with a limited resource usage. Due to the continuous evolution of OTT services, this system was designed with different approaches that can be extrapolated to future situations.By looking at the results, the proposal meets all the expectations and requirements and therefore it proves its success. The proposed design was implemented and validated with different alternatives whenever it was possible, both in wired and wireless networks. Moreover, long-time testing was performed to both ensure its stability and analyze the obtained data.

“…Every day, more than 2000 probes are performed for each test box pair. The interval between two consecutive probes is randomized according to a Poisson distribution, as recommended in [9]. The measurements done also include packet losses, path information, bandwidth and delay variation.…”

“…One approach to identify the path with the lowest delay is to probe all available paths. However, measuring adequately the delay of a path typically requires many probes, distributed over time [9]. For example, RON [10] uses at least 10 probes to estimate the latency of a path, with 14 seconds in average between two consecutive probes.…”

Abstract. IPv6 multihoming with multiple prefixes increases the number of paths available between multihomed sites. Selecting the path with the lowest delay is important for many interactive and real-time applications. We propose in this paper to use a network coordinate system as a scalable an efficient way to help hosts in IPv6 multihomed sites in selecting the best source and destination IPv6 prefixes. Relying on RTT measurements from the RIPE NCC data set, our experiments show that, using synthetic coordinates, all paths with really bad delays can be avoided. Moreover, we are able to select paths with a delay at most 20% worse than the lowest delay for more than 85% of the pairs of multihomed sites. A second contribution is SVivaldi, an improved version of the Vivaldi distributed algorithm for computing synthetic coordinates. We show that SVivaldi produces more accurate coordinates and is able to stablilize Vivaldi's coordinates.
