Abstract
Applications that are distributed, fault tolerant, or perform dynamic load balancing rely on redirection techniques, such
as network address translation (NAT), DNS request routing, or middleware to handle Internet scale loads. In this paper, we
describe a new connection redirection mechanism that allows applications to change end-points of communication channels. The
mechanism supports redirections across LANs and WANs and is application-independent. Further, it does not introduce any central
bottlenecks. We have implemented the redirection mechanism using a novel end-point control session layer. The performance
results show that the overhead of the mechanism is minimal. Further, Internet applications built using this mechanism scale
better than those built using HTTP redirection.
