A Study of the Effect of Using Kademlia as an Alternative to Centralized User Location Servers in SIP-based IP Telephony Systems
Some proposals are found on the literature for decentralizing SIP-based Voice over IP (VoIP) systems, replacing the client-server architecture for a P2P overlay network but none of the proposed solutions deploying a P2P network had studied the impacting of decentralization on call setup delay. We proposed a system using Kademlia instead of a centralized user location approach. Kademlia offers concurrent searches and this improves the latency in user location and thus provide a faster call establishment when the network experiences different delays, as showed in this study. In this paper it is also described how the system using Kademlia works as well as the tests performed in order to measure the impact on call establishment time when decentralizing a user location service on an IP telephony system.
