In the heterogeneous environment of the multi-registry centers, owing to the traditional updating data burden, the data of the affiliated registry center cannot synchronize with the root registry center in real-time. Although therefore the special UDDI service subscription mechanism had ever defined, most present UDDI registry centers don't support the function of subscription nowadays. Therefore, aiming at the problem and the limitation, the implementation method of the registry to support subscription has been proposed on the basis of analyzing the information interaction mode and function requirements of subscription. Moreover, the certain instance has been implemented with the method based on UDDI specification and Java language so as to the real monitoring, feasibility and practice to be proved.

The paper researched modeling methods for Architecture of Command and Control System Based on SOA and respectively established organization model, communication model, function model, and information model that can provide solutions and reference to the problems such as business services, communication standard, protocol unified that occur in the process of architecture of Command and Control System Based on SOA.

Denial of Service (DoS) is to make a computer or network unable to provide normal service. With more and more SOA-oriented enterprise information platform appearing, SOA security issues have become increasingly prominent and the safety of SOAP message transmission is an important determinant of SOA Security. However, the loss of Dos attack for SOA brought to society is huge and difficult to estimate. Through the study and analysis of the simulation results, the characteristic of DoS attack on the impact of system resource is summarized, which also provides the reference for the safety technology and theory.
