How the NXP ASK Embedded Networking Router and Software Converts the LS1043A Into a Smart NIC or Router
●The list of high-level goals, often seemingly conflicting, are:
■To perform routing and switching at fixed function router latency and throughputs for any packet size when using an NXP system on chip (SoC) with packet and security acceleration
■To use a well-known router stack that the industry has already accepted
■To support well-known and documented methods of setting up Linux® networking
■To utilize NXP packet and security accelerators (PFE, DPAA 1 &2, SEC) to create a “near-single-chip”programmable smart router with nearly ALL of the general-purpose processor (GPP) cycles available to programmers for value-added applications—not just pushing packets
■To provide a rapidly reconfigurable routing system that fits well with potential SDN-ish deployments Underlying these goals are some simple industry truths:
■Processing packets in software only is very slow and is sometimes actually called the “slow path.” This is particularly acute in Linux.
■Processing packets in a neat and organized software hierarchy, which roughly corresponds to the OSI 7-layer model is VERY slow. This is particularly acute in Linux.
■You can process packets 100% in software, but if you can bypass the layered software stack, the packet throughput and latency dramatically improve. This is particularly acute in Linux.
■Bypassing the layered software stack dramatically reduces CPU utilization, even if there is 100% software-only processing. This is particularly acute in Linux.
■Hardware processing, instead of software processsing, is well known in the industry to yield improvements in latency, throughput, power consumption, and CPU loading.
