Aktivní XML

This work is concerned about the usage of so called active XML for the implementation of distributed algorithms. The active XML is introduced in the form of Web Services and the XML-RPC protocol. Both of these technologies are based on the exchange of XML-based messages. While the XML-RPC protocol is nowadays an unused and almost forgotten technology, the Web Services are getting more and more attention over the last few years. The communication of Web Services is based on the exchange of SOAP messages. The interface of these services is described by WSDL files. Besides the description of these already mentioned technologies, this thesis is concerned with possible modifications of these technologies in order to implement distributed algorithms. Since the requirements of distributed algorithms, as they are conceived by the academics, are diametrically different from the requirements of business applications, for which were the Web Services developed, great compromises are necessary. The practical part of this work points at possible solutions for the usage of Web Services in the distributed algorithm computing on an exemplary implementation. Another distributed algorithm is implemented with the usage of the XMLRPC protocol and the comparison of these implementations is done
