Description
Technical Field
The invention belongs to the field of network application, and relates to a method for deploying and managing network services based on service computing and a system for deploying and managing network services based on service computing.
Background
With the development of the internet, more and more network-based application services have emerged. For network service administrators, deploying and managing different network services on different operating system platforms is a task which requires professional knowledge and is tedious and time-consuming, and it is very meaningful to research how to release the network administrators from the deployment details of various network services.
Before the advent of Web services, a significant problem faced by distributed networks was that interoperability between the various platforms was too poor due to the inter-diversity of the platforms between the various organizations, organizations. The advent of the Web services standards (WSDL, SOAP and UDDI) solved this problem. Its advantage is seamless interoperability, which allows an application written in one language on one platform to use an application service written in a completely different language on another, completely different platform. And from the e-commerce application field, the Web service can solve the problems of high maintenance cost and update cost caused by complex application connection and program codes in e-commerce application.
Because of the existence of special network services (e.g., certain types of honeypots can dynamically change the unicast IP address of a host), there are many problems with the use of unicast IP addresses by a network service management center to control and manage various network servers. Thus, conventional communication modes based on unicast or broadcast techniques limit information delivery to a particular host or all hosts in the network, and do not accommodate the dynamics of the communication. Multicast technology is an efficient data transport mechanism suitable for group communication, where a group of hosts logically belonging to a group is identified by a class D IP address, and dynamic changes in the group relationships are achieved by means of "join" or "leave" operations. Any host can communicate with all members of the group via this address. The data source only needs to send one data copy, the multicast message is automatically copied according to the needs in the network transmission process, the defects that the unicast stream establishes communication connection for each receiver and independently sends data information are avoided, and the problem that the unicast address is dynamically changed in some special services is solved.
