LTE module for packet processing for 4G

October 21, 2010 // Phil Ling

At 4G World, Kontron unveiled its second generation of AdvancedMC packet processor modules featuring the Cavium Networks OCTEON II CN6335 MIPS64 6-core processor. Kontron claims the module has already garnered interest from 4G network equipment vendors seeking a faster time to deployment using standards based hardware platforms such as AdvancedTCA and MicroTCA.

Platform design considerations for the Kontron AM4211 include using it as an eNodeB and LTE network element component or, in combination with full-scale AdvancedTCA blades, as a co-processor Network Interface Card (NIC).

The module can be scaled across both MicroTCA (Picostation, Microstation to Macrostation) and 14-slot AdvancedTCA platforms. The new features of the CN6335 processor on the Kontron AM4211 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.

This next generation packet processor module is said to offer compatible evolution and can meet numerous market requirements when designing high performance 4G network elements, including - increased data plane performance with twice the performance per Watt over existing alternatives; high density computing (9GHz) within a stringent thermal budget (< 40W on 12VDC).

It is interoperable with third party AMCs based on DSP and FPGA. With direct connectivity to FPGA/DSP AMCs in a MicroTCA platform, it is described as a complete solution for MAC processing and L3-L7 processing on single chip, achieving a high throughput of up to 15M packets per second (pps).
