...software across multiple network elements--speeding time-to-market, saving money, and freeing up key resources to focus on competitive differentiation.
Equally important, the adoption of standards-based elements enables new and emerging hardware to plug into an existing network infrastructure without extensive retooling and associated costs. It also encourages use of best-of-breed technologies without imposing vendor lock-in. For much of the new hardware being deployed in next generation networking (NGN) infrastructures, the de facto standard is the Advanced Telecommunications Computing Architecture (ATCA). ATCA is a perfect example of a standard that not only promises all the benefits of a COTS solution, but has also reached a point of maturity for wide use in real-world implementations.
Getting standards-based technologies to deliver on their intended promise requires heavy lifting and cooperation. For many industries, such as mobile phones, the proliferation of special interest groups (SIGs) has led to overlap and competing standards, resulting in a splintered, confused industry and delays in standards adoption.
In the communications industry, however, there is significant cooperation between different SIGs. In telecommunications, nearly a dozen SIGs have worked to define the technology components that fit into an overall solution. Some of the most notable SIGs include the Communications Platform-Trade Association (CP-TA), PICMG, the SCOPE Alliance, the Service Availability Forum (SAF), and The Linux Foundation.
Each communication SIG has a specific function and focus: The Linux Foundation, created by a merger between the Open Source Development Labs (OSDL) and the Free Standards Group, focuses on specifications for the Linux OS; PICMG focuses on standards for ATCA hardware; the SAF focuses on middleware above the OS; and the CP-TA...
