NMA Vendors Can Offload CPU Intensive Functions to Hardware at 10, 40, 80 and 100Gbps
As a network monitoring appliance (NMA) vendor it is likely you rely on industry standard servers from Cisco, Dell, HP, or Super Micro for your hardware needs and spend much of your R&D budget on software. This generic hardware with proprietary software solution is often not powerful enough to handle the 10, 40, 80 and now 100 gigabits of network traffic these appliances receive.
Hardware-based Host CPU Offload Options
When software and a standard x86 CPU is not enough there are various hardware-based host CPU offload options available: 1) ASIC, 2) Network Processor (NPU) or, 3) FPGA.
Each option is bound by at least three requirements:
- The solution must fit into an industry standard server
- Require no major modification to the vendor’s software
- Be cost effective
The RTC Magazine article below illustrates the pros and cons of each of these options.
