BS EN 61907:2010 pdf free.Communication network dependability engineering.
BS EN 61907 This International Standard gives guidance on dependability engineering of communication networks. It establishes a generic framework for network dependability performance, provides a process for network dependability implementation, and presents criteria and methodology for network technology designs, performance evaluation, security consideration and quality of service measurement to achieve network dependability performance objectives.
This standard is applicable to network equipment developers and suppliers， network integrators and providers of network service functions for planning, evaluation and implementation of network dependability.
The following referenced documents are indispensable for the application of this standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Terms and definitions For the purposes of this document, the terms and definitions given in IEC 60050-191 and the following apply.
communication network system of communication nodes and links that provides transmission of analog or digital signals.
The nature of network operation is multi-faceted and ever expanding and evolving such as doing business on-line via the Internet. The infrastructure connecting different types of communication systems and interacting networks is extremely complex. The integration of disparate networks and systems demands evolving establishment of interfaces and protocols for interoperability to attain viable network connectivity and service performance. Enterprise marketing and e-commerce pressures often dictate development of new techniques that change the ground rules in business and service applications.
Network related activities are unique in assuring dependable performance and quality of service. The challenge is to provide network solutions that link network designs and service function applications to realize the relevant dependability attributes. Network dependability infers that the network performance is able to maintain information integrity and capable of delivering the network service functions to satisfy user expectations as well as the service provider’s needs. The strategic framework is to select and implement appropriate network elements for the network configuration to achieve dependability and integrity in network performance.
Annex A presents a generic communication network model and related concepts. Network dependability and network service functions are influenced by the dependability attributes relevant to their specific applications in various network life cycle stages.These dependability attributes include availability, reliability, maintainability, maintenance support performance, recoverability and integrity performance characteristics, incorporated in the network designs and implemented in the network service functions for network operation and maintenance.BS EN 61907 pdf download.
