Web Services are an emerging software technology that
employ XML to share and exchange data. They may serve
as wrappers for legacy data sources, integrate multiple remote
data sources, filter information by processing queries
(function shipping), etc. With those that interact with an end
user, a fast response time might be the difference between a
frustrated and a satisfied user. A Web Service may employ
a loss-less compression technique, e.g., Zip, XMill, etc., to
reduce the size of an XML message in order to enhance its
transmission time. This saving might be outweighed by the
overhead of compressing the output of a Web Service at a
server and decompressing it at a client. The primary contribution
of this paper is NAM, a middleware that strikes a
compromise between these two factors in order to enhance
response time. NAM decides when to compress data based
on the available client and server processor speeds, and
network characteristics. When compared with today’s common
practice to transmit the output of a Web Service uncompressed
always, our experimental results show NAM either
provides similar or significantly improved response times
(at times more than 90% improvement) with Internet connections
that offer bandwidths ranging between 80 to 100
Mbps.
