Abstract-- Emergent wide-area distributed systems like com-
putational grids present opportunities for large scientific ap-
plications. On these systems, communication mechanisms have
to deal with dynamic resource availability and occurrence of
network failures. In this paper, we present the design and imple-
mentation of an asynchronous and persistent pipe mechanism,
called -channels. These communication issues are addressed
by combining adaptive caching with data streaming for efficient
and fault-tolerant communication. We present the underlying
distributed algorithm that implements (a) caching of pipe data
segments; (b) asynchronous operation; and (c) re-establishment
