In numerous countries, the nation-wide roll-out of high-speed Internet access is progressing slowly, in particular in rural areas, where the investment of laying fiber is high compared to potential revenue. Regulatory pressure however has forced ISPs …
Application Layer Traffic Optimization (ALTO) allows operators to guide the peer selection of P2P applications. Using ALTO, operators can reduce inter-domain transmissioncosts while at the same time P2P applications can improve their performance. …
Networks rely on broadcasts and multicasts for some of the most basic services such as auto-configuration. In the recent past, application layer protocols have increasingly made use of the broadcast mechanism. Examples of these applications include …
Network measurements are essential for network operations and troubleshooting. A number of network measurement projects have developed measurement platforms to not only assess the state of individual networks and services but target certain aspects …
Standardization of Internet protocols is usually a somewhat slow process. The reasons for this are manifold. Besides working out the protocol details, things like opposing stakeholder interests can prolong the consensus building process, new …
The network measurement community has produced an impressive set of network measurement tools to which a few are added each year. A few prominent examples have seen wide-spread deployment covering large parts of the Internet but there is arguably one …
Inter-domain traffic engineering is an important aspect of network operation both technically and economically. Traffic engineering the outbound direction is less problematic as routers under the control of the network operator are responsible for …
Capacity sharing – the fair usage of the available capacity amongst a set of users – is relying solely on the end user/end hosts in today’s Internet. This in principle allows malicious end users to consume disproportional amounts of capacity without …
The looming depletion of the public IPv4 address space has recently inspired a number of proposals intended to work around the inevitable address shortage. Broadly, all of these can be classified as address sharing, tunneling and translation …
Application Layer Traffic Optimization (ALTO) is a means for operators to guide the resource provider selection of distributed applications. By localizing traffic with ALTO, Internet Service Providers (ISPs) aim to reduce the amount of costly …
