Classification of unicast and multicast routing protocols for interior and exterior routing: RIPv1/2, RIPng, OSPFv2/3, IGRP, EIGRP, IS-IS, MOSPF, DVMRP, PIM-DM/SM;
Study and classification of alternative group communication technologies like:
CastGate, XCast, XCast+, ESM and HyperCast.;
Measurement of join latency, control overhead, forwarding delay and jitter for the
following multicast routing protocols: DVMRP, PIM-DM and PIM-SM;
Determination of the effects of bidirectional tunneling in Mobile IPv6;
BGP4 exterior routing protocol was studied by a detailed analysis of the finite state
machine (states: Idle, Connect, Active, OpenSent, OpenConfirm, and Established) using
ns-2 simulator;
The performance parameters for AGCS technologies: stress, resource utilization,
stretch, time to first packet and control overhead were evaluated;
Enhancement of CastGate technology by using the CastGate router together with
the PIM-SMv2 multicast routing protocol in IPv4;
Extension of CastGate technology in order to allow the transmision of IPv6
multicast traffic over IPv4 tunnels;
Enhancement of XCast/XCast+ technology by using the PIM-SMv2 multicast
routing protocol on routers and hosts;
The design and implementation of a new translation mechanism for multicast data
and associated SAP/SDP messages.
