Description of the Self-Chord P2P Application

This paper presents the implementation of the “Self-Chord” P2P system. Self-Chord inherits the ability of Chord-like structured systems for the construction and maintenance of an overlay of peers, but features enhanced functionalities deriving from ant-inspired algorithms, such as autonomy behavior, self-organization and capacity to adapt to a changing environment. Self-Chord has three main advantages with respect to classical structured P2P systems, especially in the context of Grid and Cloud Computing: (i) it is possible execute range queries efficiently; (ii) the load balance among peers is improved; (iii) maintenance load is reduced because resources are spontaneously redistributed when peers disconnect or reconnect to the systems, or when resources are added/modified. In this paper, we summarize the main functionalities of the Self-Chord application, and illustrate the configuration and parameter settings, with the help of an example.
