Cavium, Kontron and Tata Elxsi Demo LTE eNode B

Cavium Networks Kontron and Tata Elxsi will showcase an LTE eNodeB solution at next week's Mobile World Congress 2011 in Barcelona based on Cavium OCTEON II multi-core processor as part of Kontron's open standard hardware running Tata Elxsi's LTE eNodeB L2/L3 software stack. The joint solution offers 3GPP Release 8 compliant LTE Layer 2 and Layer 3 processing that is capable of delivering up to 450 Mbps of aggregate throughput from a single AdvancedMC module featuring the OCTEON II CN6335 cnMIPS64 6-core processor.



The Cavium OCTEON II CN63XX processor family provides up to 9GHz of compute with a large 2MB L2 cache, DDR3 memory controller, security acceleration for SNOW 3G and KASUMI, TCP/IP, DPI, QoS and packet processing acceleration. Maximum power ranges from 7 to 17 watts from low-end to high-end. The OCTEON II processors have been designed into a range of tier-1 OEM systems ranging from eNodeB to packet-core platforms and services rich wireless infrastructure gateways.



The Kontron AM4211 ATCA Mezzanine Card (AMC) module can be configured with ATCA node blades and MicroTCA platforms (Picostation, Microstation to Macrostation). It is designed to support 1x 10GbE to the front and software configurable interfaces to the Fabric with either 2x PCIe x4 or SRIO which expands its application usage when configuring systems in combination with standards based third-party Digital Signal Processing (DSP) AMCs.



For control plane functions the Kontron AM4211 provides GbE on Ports 0 and 1 connected to the CN6335 processor and is fully software compatible with previous generation Kontron AMC packet processing modules, AM4204, AM4210 and AM4220, all based on OCTEON Plus processors from Cavium Networks. It is configurable with the Kontron MicroTCA 1U carrier-grade platform OM6061.



Tata Elxsi has architected its LTE eNodeB L2/L3 protocol stack to leverage the advanced hardware acceleration capabilities available in Cavium's OCTEON II multi-core processors, thereby delivering market-leading performance and scalability. The Tata Elxsi L2/L3 protocol stack also exploits the ability of the Cavium OCTEON II to support multiple virtual operating systems including Linux and Simple Executive to accelerate data plane performance.http://www.caviumnetworks.com
