The aTCA-N700 is a single slot AdvancedTCA® (ATCA) blade powered by dual OCTEON II multi-core processors for high performance packet processing applications such as IPTV, LTE wireless, security and many more areas. The blade provides up to 40Gbps full duplex packet processing performance with flexible network interfaces.
The aTCA-N700 is designed to provide high performance security enabled intelligent deep packet inspection and processing functions that are required by high-end network appliances, security appliances, switches, and servers. The major building block is the Cavium CN6880 packet processor subsystem.
The Cavium CN6880 has 2MB of L2 cache which is shared by 32 cnMIPS cores. Each cnMIPS core also has dedicated 37K lcache and 32K Dcache. DDR3 memory has a total of 400Gbps bandwidth. Hardware acceleration blocks are also available for the most advanced networking and security application. The RegEx engine enables high throughput pattern matching with optional co-processors.
The blade also has a high performance, non-blocking, local switch fabric to interconnect the CN6880, backplane, and I/O ports altogether. This feature allows the data path to be configured in many different ways to fully utilize the multi-core CPUs and provide the flexibility for application programming. There are 3 modes of data path operation: serial, parallel, and by pass, which can be configured depending on the application requirements.
The application areas of the blade are summarized but not limited to:
Wireless backhaul aggregation Switch/Router, which requires Deep Packet Inspection capability
Security Appliances such as Firewalls, VPN and IDS/IPS
Content based fine grain load balancing switches
Front end I/O card with traffic management for high capacity, value added appliances for multi-service offering
Network Monitoring and Analysis Services
Ethernet aggregation nodes
ADLINK Software for Network (ADSN) Product Brief
With the exponential growth of data traffic, service operators need increasing amounts of switch bandwidth to keep up with operational demands. The 40G switch has now become mainstream, superseding the 10G-based switch, and will eventually be replaced by the 100G switch as the industry standard in the near future. As a telecom and network platform provider, ADLINK supplies 10G & 40G ATCA products and has developed the ADLINK Software for Network that allows customers to configure, manage and monitor ATCA switch blades and NPU-based processor blades.
The ADLINK Software for Network is a comprehensive, optimized middleware designed to allow operators to easily configure, manage and monitor switch status. It includes support for Layer 2 (IEEE 802.3), Spanning Tree Protocol (STP-IEEE 802.1D), VLAN support (IEEE 802.1Q), Link Aggregation Control Protocol (LACP-IEEE 802.3AD) and switch statistics. For Layer 3 protocols, the ADLINK Software for Network supports wire-speed layer-3 packet routing base on route protocols such as RIP/OSPF/BGP. To fulfill different complex requirements, the ADLINK Software for Network also integrates with the Linux kernel to support miscellaneous features such as ACL/High-Availability. In addition, the ADLINK Software for Network not only provides a traditional command-line interface for management, but also includes libraries and APIs for further customization and integration with customers�� management systems.
