PICMG® 2.16 Tutorial - continuedSummary | Introduction | Evolution | Limitations of the PCI Bus | Time-to-Market Key Features SummaryIncreased inter-board communication: All sub-systems will operate as stand-alone "systems on a card" interfacing with each other through a network stack on top of Ethernet. Standards-based architecture: Standards-based architectures like PICMG 2.16 enable engineers to develop solutions in a shorter time, with a lower total cost of ownership - allowing them to focus on their core competencies. For many equipment developers, this has become the 'software applications and operating environment' that make their product unique. Increased throughput/density/performance: Offers throughput rates up to 40Gbit/sec full duplex, more than an order-of-magnitude improvement over CompactPCI® implementations. Decreased time-to-market: Because PICMG 2.16 leverages existing CompactPCI and Ethernet technology, design engineers can quickly implement a 2.16 design without extreme changes to development techniques or system footprint. Reduced integration time: Development occurs at the network/transport layer, NOT at the link (driver/backplane) level. This drastically reduces integration time - while increasing system scalability, reliability and performance. Increased scalability: Unlimited "virtual backplanes." Increased reliability: The platform accommodates two fully redundant networks within a single chassis, potential system losses are limited to a single slot in a chassis - the ultimate hot-swap failsafe. Also, cables and connectors, the LAN elements most prone to failure, are eliminated - creating a more reliable network. Leverages ubiquity of Ethernet: Ethernet is everywhere. 95 percent of world-wide data travels on Ethernet. 85 percent of installed networks are Ethernet. And Ethernet technology continues to be incorporated into more product than ever before. Applications
VoIP Media Gateway Architecture (centralized management/non HA)
Discrete VoIP Media Gateway Architecture (de-centralized management/HA)
Integrated Access Device (centralized management/non-HA)
IP DSLAM Architecture (de-centralized management/non-HA)
Server Clustering Architecture (de-centralized management/non-HA) Related SpecificationsCompactTCA CompactTCA uses the CompactPCI mechanicals and bundles many of the fragmented specs found in the PICMG 2.x family. The objective is to clearly define an embedded system platform specification. The key element of the CompactTCA specification is that it retains compatibility with most existing CompactPCI/PICMG 2.16 products. The proposed CompactTCA architecture complements AdvancedTCA® by featuring PICMG 2.16 packet switching as the primary interconnect, mandatory system management and elimination of the PCI bus for data transfer. Much like PICMG 2.16, CompactTCA is expected to be an "edge-level" technology. AdvancedTCA AdvancedTCA is a completely new architectural design with a focus on telecommunications applications. AdvancedTCA was recently ratified as a standard in December of 2002. With a much larger overall form factor and less granularity at the board level, it is anticipated that AdvancedTCA will complement other standards-based architectures, like PICMG 2.16 and CompactPCI, by offering an alternative to non-proprietary architectures. Because of its size and functions, it most likely will be adopted as a "core-level" technology versus an edge level technology. Core applications require extremely high bandwidth and are less affected by cost. Additional Information
