Small Cell Integrated Backhaul (SIB) Application Solutions Kit (ASK) for the LX2160A and LS1046A Processors
This 5G small cell integrated backhaul application solutions kit (SIB ASK) offloads the main CPU by sending packets through NXP security hardware and through packet fastpath implemented in hardware or software. Use existing IPTABLES and firewall rules to configure. The CPU cycle savings from fastpaths provides large boosts in CPU utilization, packet throughput, packet latency and even power.
Leverages Linux stack for initial connection processing and session learning.
Bulk of the data traffic is offloaded through fast path engine. Thus provides large boosts in CPU utilization, packet throughput, packet latency and even power.
Hardware based QoS(CEETM) offers strict priority queuing(SPQ) and weighted bandwidth fair scheduling(WBFS)

Features
Software Details (NXP Fast-Path Packet Processing)
- Fastpath Packet Engine provides bypass of the Linux Stack saving substantial CPU cycles
- Two fastpath technologies : ASF for CPU-based bypass / DPAA(ASK) for HW based bypass
- No specialized Linux user space programming. Just use Linux (nfconntrack, iptables(firewall rules))
- Excellent integration with NXP hardware security(CAAM) for fast key exchange and fast symmetrical ciphers
- QoS offload through CEETM hardware
