Ph.D Thesis Proposal :
[Proposal 01]
Several models and architectures are proposed to
support Multiparty VoIP (MVoIP) services. Initial solutions are based
on network infrastructure and use routers to redirect live streams for
large groups of participants by using multicasting addresses. Since not
all routers in the Internet are IP-multicast enabled, this creates a
major deployment problem. To overcome this shortcoming, actual MVoIP
solutions implement multicast services on top of the IP unicast service
of end-systems. The aim is to create an overlay communication topology
based on application-links known as Application Layer Multicast (ALM)
systems. ALM brings the advantage of requiring only application
software installation on host peers without any added network
infrastructure.
The aim of this thesis is to study
different MVoIP architectures, and to propose a P2P model
adapted for Large Scale Communication.
The
Quality of exchanged media flow on the porposed architecture can be
assessed and compared with previous models using omnet Simulation
environment (with INET) and ffmpeg codecs.
