CLIO - A Cross-Layer Information Service for Overlay Network Optimization
نویسندگان
چکیده
New overlay-based services aim to provide properties like resilience, availability or QoS. To achieve this, automatic organization and optimization is required, which again demands accurate information on the network. Collecting and exchanging this data has a significant impact on the network, especially if several overlays are used on the same host. In this paper, we provide a survey of the current state of the art and identify challenges which must be addressed in order for new overlaybased services to be successful. We present our own solution CLIO, a cross-layer information service for overlays. CLIO provides information for the automatic creation and optimization of overlays. The service supports multiple overlays on the same node, the provided information is overlay-independent, and collected information is reused.

Multicast services can be provided either as a basic network service or as an application-layer service. Higher level multicast implementations often provide more sophisticated features, and can provide multicast services, where no network layer support is available. Overlay multicast networks offer an intermediate option, potentially combining the flexibility and advanced features of applicati...

متن کاملInternet Design Principles for Economic Traffic Management
Traditional traffic management techniques employed by Internet Service Providers (ISP) cannot successfully deal with the increasingly high volumes of overlay traffic and lead both overlay and underlay to sub-optimal behavior. Individual optimizations as performed on each different layer result in low Quality-of-Experience (QoE) for the overlay users and, therefore, limited business opportunitie...
