Foreword This Technical Report (TR) has been produced by ETSI Technical Com

15、mittee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). Introduction The focus of the present Technical Report is on identifying the emerging requirements for exposing NGN services and capabilities and on summarizing some of the technologies for acco

16、mplishing the goal. At the current time, NGN services and capabilities are being exposed by different technological means. There have been a number of causes for using a wide range of technologies. The most notable include: Historical usage of certain protocols in certain networks. Varying considera

17、tions in protocols timing, bandwidth consumptions, and extensibility. Different security requirements. The drives and imperatives behind the present effort include: NGN (including IMS) is on its way to become the global reference architecture encompassing different networks and technologies. Realiza

18、tion that in competitive reality, the design, implementation, integration and the deployment stages of both NGN and external to NGN services and applications continue to shorten, become more automated and of ad-hoc nature. The NGN boundaries, many times in the past defined by regulatory rules and as

19、sumptions, are a moving target and vary greatly worldwide. As a result, the present Technical Report identifies new emerging requirements and, in the same time, analyzes the relevance of some previous working assumptions. ETSI ETSI TR 181 020 V1.1.1 (2008-03) 6 1 Scope The present document: Identifi

20、es requirements for flexible and agile service development and deployment for a multi-provider and multivendor environment. Surveys the technical approaches available (e.g. Web services) to expose the functionalities and identify any possible impacts in the evolution of the TISPAN architecture and m

21、anagement. Surveys the existing industry efforts in this domain (e.g. TISPAN/NGN (protocols), Parlay/X, OSA, OMA, ITU-T, OASIS, WS-I, W3C, among others) and relationship with management frameworks (e.g. DMTF/TMF) Identifies next steps. 2 References References are either specific (identified by date

42、 the present document, the following abbreviations apply: 3GPP CT5 3GPP Core Network the Simple Object Access Protocol (SOAP) 3 provides the semantics for data exchange; and the Web Services Description Language (WSDL) 4 provides a mechanism to describe the capabilities of a Web service. Additional

43、specifications, collectively referred to as the WS-* architecture 5, define functionality for Web services discovery, event handling, attachments, security, reliable messaging, transactions, and management. The most important attribute of the WS-* architecture 5 is composition. Protocol composition

44、enables incremental development of Web services solutions only as individual requirements (such as security, reliable messaging, attachments, discovery, etc.) are needed. In isolation, each of these requirements solves an elemental need. In composition, they address higher-level functionality common

45、ly required by distributed applications. As such, the WS-* specifications can be used either independently or in combination with one another. This eliminates the complexity and overhead associated with specifications that attempt to define multiple capabilities or are tightly coupled with other spe

46、cifications. It also enables developers to apply only the specific functionality needed to solve the immediate need. As new application requirements arise, new specifications can be authored without compromising backwards compatibility. The high level Web services protocols stack is presented in fig
