 | Network monitoring and diagnosis systems are used by ISPs for daily network management operations and by popular network applications like peer-to-peer systems for performance optimization. However, the high overhead of some monitoring and diagnostic techniques can limit their applicability. This is for example the case for end-to-end available bandwidth estimation: tools previously developed for available bandwidth monitoring and diagnosis often have high overhead and are difficult to use.

| The ability to locate network bottlenecks along end-to-end paths on the Internet is of great interest to both network operators and researchers. For example, knowing where bottleneck links are, network operators can apply traffic engineering either at the interdomain or intradomain level to improve routing. Existing bandwidth measurement tools fail to identify the location of bottle-neck links. In addition, they often require access to both end points and generate huge ... |

 | Detecting the points of network congestion is an intriguing research problem, because this information can benefit both regular network users and Internet Service Providers. This is also a highly challenging problem, because the Internet is designed to provide only end-to-end services, and its internals are in principal invisible to end users. Current techniques used to detect bottleneck positions have problems such as high probing overhead and low measurement accuracy. In ... |

| The packet pair mechanism has been shown to be a reliable method to measure the bottle-neck link bandwidth of a network path. However, the use of packet pairs to measure available bandwidth has had more mixed results. In this paper, we study how packet pairs and packet trains can be used to estimate the available bandwidth on a network path. As a starting point for our study, we construct the ... |
