Abstract:
Web services (WS) implements Service-Oriented Architecture
(SOA). WS extends World Wide Web (WWW) infrastructure.
This provides a means of integrating software applications in
loosely coupled distributed systems. WS communication is
facilitated by Simple Object Access Protocol (SOAP). SOAP
offers a simple and lightweight mechanism for exchanging
structured and typed information among peers in a decentralized,
distributed computing environment. However, SOAP’s
transmitted data is represented in XML. XML documents are
huge in size and verbose (highly redundant), and processing of
XML information and its conversion to and fro memory data
types are some of the major hindrance in performance for high
performance applications. This survey paper gives an insight of
previous researchers’ contributions on techniques used in
optimizing SOAP in communication in WS in terms of
bandwidth utilization and throughput. To optimize SOAP,
several techniques covered include: client side caching,
differential serialization, SOAP binding, compression, server
side caching, and differential deserialization.
