Overlook: Scalable Name Service on an Overlay Network
نویسندگان
چکیده
This paper indicates that a scalable fault-tolerant name service can be provided utilizing an overlay network and that such a name service can scale along a number of dimensions: it can be sized to support a large number of clients, it can allow large numbers of concurrent lookups on the same name or sets of names, and it can provide name lookup latencies measured in seconds. Furthermore, it can enable updates to be made pervasively visible in times typically measured in seconds for update rates of up to hundreds per second. We explain how many of these scaling properties for the name service are obtained by reusing some of the same mechanisms that allowed the underlying overlay network to scale. Finally, we observe that the overlay network is sensitive to bandwidth and CPU limitations.

Towards Scalable and Robust Overlay Networks
Every peer-to-peer system is based on some overlay network connecting its peers. Many of the overlay network concepts proposed in the scientific community are based on the concept of virtual space. These designs are usually highly scalable, but they do not guarantee robustness against adversarial attacks, especially when considering open peer-to-peer systems. In these systems, determined advers...

متن کاملDistributed QoS Routing for Backbone Overlay Networks
In recent years, overlay networks have emerged as an attractive alternative for supporting value-added services. Due to the difficulty of supporting end-to-end QoS purely in end-user overlays, backbone overlays for QoS support have been proposed. In this paper, we describe a backbone QoS overlay network architecture for scalable, efficient and practical QoS support. In this architecture, we adv...
متن کاملData Driven SMART Intercontinental Overlay Networks
This paper addresses the use of Big Data and machine learning based analytics to the real-time management of Internet scale Quality-of-Service Route Optimisation with the help of an overlay network. Based on the collection of large amounts of data sampled each 2 minutes over a large number of source-destinations pairs, we show that intercontinental Internet Protocol (IP) paths are far from opti...
متن کاملA Scalable Hybrid Overlay Multicast Architecture for Large-Scale Applications
We propose a two-tier overlay multicast architecture to efficiently support large-scale multicast applications. In this architecture, overlay multicast scheme is adopted in the backbone domain, while application-layer multicast protocol is responsible for the communication between the limited number of end users in access domains. Our two-tier architecture is able to provide efficient resource ...
