An Overview and Comparison of Hierarchical P2P-SIP Networks
P2P-SIP networks are emerging distributed communication
technology introducing Scalability and Robustness.
These networks propose to use a peer-to-peer network for user
registration and user location in Session Initiation Protocol (SIP)-
based voiceover- IP (VoIP) networks.
Nevertheless, P2P-SIP systems are based on a pure flat
DHT design which provides a uniform distribution of (equal)
peers and resources that assures scalability and load balancing.
Recent research works have proposed to organize P2P overlays
into hierarchical architecture called HP2P-SIP. These later are
motivated by supporting sophisticated search requirements, separating
categories of use (content, personal communications,),
scaling, etc. However, these works did not resolve the problem
of overloading the bandwidth, which is still a head-case.
In this paper, after highlighting the many challenges of
hierarchical architectures, we show how to avoid overloading
the physical network by acting on the overlay network. To do
this, we have a physical network of size N with a number of
super nodes (NSN). Our solution shows how many levels k we
must build our overlay network so that in the physical network,
the number of messages generated by the lookup nodes does not
exceed a value x, initially fixed. x
