Proposals for the way forward - One view from core networks Staffan Skogby Strategic Product Manager Huawei Technologies Sweden AB – R&D Center Staffan.Skogby@huawei,com June 4th, 2009

Huawei company – on one slíde Founded in 1988, Huawei Technologies is one of the fastest growing telecommunication and network solutions providers in the world. It is one of the worldwide leading suppliers in the field of Broadband Network (NGN, DSL, MSAN), Mobile Network (GSM/GPRS, UMTS, CDMA), Optical Network, Data Communication, Software and Applications (Intelligent Network). Huawei Technologies experienced a fast growth in the last decade with offices in more than 50 countries in the world and supplied its diversified products and solutions to more than 60 countries.

OpenSAF in the Platform Landscape To explain a bit more, the Carrier Grade Platform architecture is comprised of the following major areas: Operations and Maintenance Tools (development, deployment, and remote debugging or tracing) Application Services Carrier Grade Base Platform (of which Specialized Processing Engines are a part) The focus areas of the SCOPE Alliance to date have been the Carrier Grade Base Platform and related tools. For these areas NEPs are increasingly sourcing commonly available components based on open specifications. Specifically, these include Hardware, Operating System, Software Virtualization, Base Platform Middleware, Carrier Grade Base Platform Management and Configuration, as well as low-level development, debugging and profiling Tools. The reference architecture is purely a logical representation. A group of Network Equipment Providers (NEPs) have formed the SCOPE Alliance [SCOPE] under the IEEE-ISTO with the intent of developing profiles for as well as identifying gaps in existing open specifications and prioritizing the importance of implementations of these specifications in the Carrier Grade Base Platform (CGBP) ecosystem. NEPs have an overriding requirement for hardware and software in their carrier class solutions, namely that they be “Carrier Grade,” with all of the high availability, service reliability, retainability/ failover capability, quality, and performance that this implies. Hardware: the equipment that makes up a network platform Software: programs and instructions that run on a computer platform Components: represents a set of resources including hardware and software resources that comprise building blocks that make up a carrier grade base platform Middleware: carrier-grade base platform middleware contains platform-level services such as support for service availability, but not application services such as databases or application servers Operating system: essential program that maintains software, files, devices and runs applications Network Element: a physical node within a telecom network Application: aggregates components to provide a higher level of service Service: refers to operator services and high-level services. A service is a set of actions that satisfy a request from a user or other system. For example, database servers satisfy requests for updates, inserts, or queries. Services may surround other subsidiary services. For example, a database-driven Web service will invoke database servers Availability: in general refers to the probability that a system is in an operating condition that allows it to provide the service(s) for which it is intended to perform. Availability is a measure that conventionally is expressed as a percentage which is calculated as the uptime divided by the uptime plus the downtime of the system. For this consideration it makes no difference whether the downtime is planned or unplanned. Often availability is expressed as the number of nines (e.g., 99.999% is expressed as five 9’s and this translates to approximately 5.26 minutes of downtime per year). Retainability: ensure continuity of a service. Carrier Grade Base Platform: The common platform made up of standardized hardware and software components. CGBPs provide the foundation upon which NEPs will efficiently construct network elements. What to do? Analyze the maturity of the industry chain in terms of terminals, services, standards, patents, key technologies and key chips Evaluate how technical changes drive or limit the new product Why? Maturity of industry chain: Without key technologies, the product can be nothing but a concept only; without a chip to ensure good performance, the product can be nothing but a prototype; without a terminal, the product is of no commercial value. Choose the right time, right place and right technology.

Thank You OpenSAF Web Site http://www.opensaf.org/ Many NEPs have endorsed the concept of the OpenSAF initiative, including Ericsson (NASDAQ:ERIC), Motorola’s Networks and Enterprise business, Nokia (NYSE: NOK), Nortel (NYSE: NT), OKI (TYO: 6703), and Siemens Networks. Several providers of computing and communications technology also have indicated support for the OpenSAF initiative including Interphase (NASDAQ: INPH), MontaVista Software, Inc., and Wind River (NASDAQ (WIND).
