This paper presents a multicast routing mechanism supporting the classical IP multicast service model that can dynamically use redundant forwarding in the parts of the network affected by a high rate of topology changes, while converging to regular multicast distribution trees where or when the network becomes relatively stable. The rationale is that intermittent connectivity directly affects the...
We present a new approach to performing adaptive, loop-free, destination-based unicast forwarding in an IP-based network. The approach is an integration of several well-known techniques, including broadcast-based flooding, on-demand route discovery, and link state routing. In this approach, routers are not universally in one routing mode, such as a ‘link-state’, for all destinations but instead apply...
Estimation of Available Bandwidth (AB) for an end-to-end network path allows traffic sources to judiciously regulate the volume of application traffic injected into the network. Bandwidth estimation between two red-black network boundary nodes can enable efficient admission control of new sessions and congestion control of existing sessions through the black network. In this paper we have modified...
