A P2P Virtualization for Distributed Adaptive Conference Management
Wolfgang Kellerer und Thomas Magedanz (Hrsg.) GI/ITG KuVS Fachgespräch: NGN Service Delivery Platforms & Service Overlay Networks

Marker: TI-I

Zusammenfassung: An increasing number of popular conferencing applications operate in a lightweight, infrastructure-independent ad hoc fashion. These P2P-type systems raise the demand for scalable, adaptive self organization of conferencing in a standard-compliant way. We present a SIP-based approach to scalable distributed conference management in a Peer-to-Peer environment. The protocol distributes locators for a conference focus in a transparent fashion and makes use of the P2PSIP overlay to virtualize the focus identifier.

Peer the Peers: An Overlay ID Assignment Service at Internet Exchange Points
Proc. of the ACM SIGCOMM CoNEXT. Student Workshop , Seite 45--46.
Verlag: ACM, New York

Marker: TI-I

Zusammenfassung: P2P networks enable end users to establish services relying neither on a dedicated infrastructure nor on an ISP deployment of enhanced services at the network layer. Regrettably, overlay traffic is not optimal with respect to native connections and peering agreements, but may decrease network quality at end users at increased transit costs. This issue has been addressed by traffic localization approaches: The general objective is to keep overlay traffic local and to minimize provider crossing. Current efforts foster provider-assisted solutions. Overlays, which approximate network paths from the underlay, promise to significantly limit inter-domain traffic. However, ISPs offering transits rejoice in additional traffic and may provide localization data to de-localize peers. In this paper, we argue that ISP interaction should be provided by neutral authorities, namely the Internet exchange points. We present an architecture which serves unstructured and structured overlay peers with a sloppy generic overlay ID that jointly reflects AS-paths and peering topologies, and is unbiased by unilateral ISP interests.

An a Priori Estimator for the Delay Distribution in Global Hyrid Multicast
Proc. of the ACM SIGCOMM CoNEXT. Student Workshop , Seite 19--20.
Verlag: ACM, New York

Marker: TI-I

Zusammenfassung: Hybrid multicast is regarded a promising technology to overcome the inter-domain deployment problem for group communication. Realistic performance estimators are difficult to obtain due to the diversity of overlay concepts and their complex dependence on the global Internet topology that withstands straightforward simulations or measurements. We contribute a simple analytic model for the expected delay distribution. Parametrized by realistic measurement values, this should serve as a first order estimator for quantifying the delay penalties in a global-scale hybrid multicast packet distribution. We diagnose a strong dependence on hop counts and proximity awareness for the overlay multicast approach in use with promising results for most efficient schemes.
