Abstract—Packet loss and end-to-end delay limit delay sensitive
applications over the best effort packet switched networks such as
the Internet. In our previous work, we have shown that substantial
reduction in packet loss can be achieved by sending packets at
appropriate sending rates to a receiver from multiple senders,
using disjoint paths, and by protecting packets with forward error
correction. In this paper, we propose a Path Diversity with Forward
error correction (PDF) system for delay sensitive applications over
the Internet in which, disjoint paths from a sender to a receiver are
created using a collection of relay nodes. We propose a scalable,
heuristic scheme for selecting a redundant path between a sender
and a receiver, and show that substantial reduction in packet loss
can be achieved by dividing packets between the default path
and the redundant path. NS simulations are used to verify the
effectiveness of PDF system.
