Streaming services have been gaining much popularity in the Internet. The widespread adoption of broadband residential access enables individual users to use new bandwidth demanding services. Peer-to-Peer (P2P) multicasting approach using an overlay network to provide communication between peers is a valuable proposal for streaming since it provides rapid deployment at relatively low cost. Most of...
Multicast has been being developed as a very promising technique to data delivery to a group of destinations simultaneously. Except of first implementation for multicasting in the Internet aka IP Multicast, for past few years some systems defined for end-hosts overlay network have been successfully designed and implemented. Additionally, overlay multicast defined for end-host based networks has been...
Most of previous research on survivable networks has been focused on protecting the unicast traffic against random failures. In this paper we propose a new approach, called RA (resistant-to-attack), to provide protection of anycast and unicast communications against attacks on irregular (e.g. scale-free) networks. We use the single backup path approach to provide protection against a single node failure...
Most of previous research on survivable networks has been related to unicast communications. In this paper we propose a new approach to network survivability of anycast communications. To the best of our knowledge, anycast defined as one-to-one-of-many technique has not received much attention recently. To provide network survivability, we use the single backup path approach, i.e. each demand has...
Various streaming services have been gaining much attention in the Internet. In order to reduce the investment cost many companies decide to offer the streaming by the use of the application-layer multicasting constructed on the top of an overlay network. In this paper we address the problem of overlay networks design. The main goal is to minimize the cost of access links selected for nodes participating...
Concepts of network virtualization and overlays are nowadays gaining much popularity and are perceived as key approaches for future Internet. One of possible applications used in overlay networks is live streaming based on Peer-to-Peer (P2P) multicasting. This paper deals with the problem of overlay networks dimensioning. In the problem-formulated as an Integer Program - access link capacities are...
At the present time there are many Peer-to-Peer (P2P) multicasting systems supporting live streaming, i.e. real-time dissemination of various content issued at a source node towards a set of receivers. The objective of content distributing can be twofold: maximization of the system throughput (i.e. the streaming rate) and minimization of the streaming cost while guaranteeing the particular streaming...
Peer-to-Peer (P2P) systems have gained much popularity over the past few years. P2P networks contribute a significant portion of the Internet traffic and cause increasing costs incurred by Internet service providers (ISP). Present P2P systems are generally selecting peers in random manner, regardless of the network cost, which generates much redundant traffic over the core network and congest the...
Grid structures are increasingly considered as very convergent with peer-to-peer networks. This paper presents a model of network acting both as grid and peer-to-peer network, used for data computation and distribution. Presented PPLC algorithm is a complete solution for both grid and peer-to-peer points of view. Problem formulation is presented, as well as solution heuristic algorithm and research...
