Enterprise Network Evolution: Technical Dissection of Next-Gen Switching Architectures

As enterprises grapple with 47% annual growth in IoT endpoints and 800G uplink demands, the choice between Huawei’s S5735-S and S5735-L switches has become critical for future-proofing network infrastructure. This technical analysis deciphers how these switches balance performance, power efficiency, and operational agility in hyper-connected environments.

​Silicon-Level Performance Analysis

The S5735-S and S5735-L employ distinct ASIC architectures optimized for different traffic profiles:

S5735-S (Performance-Optimized):

  • ​Broadcom Tomahawk 3 Chipset: 6.4Tbps shared buffer
  • ​Cut-Through Latency: 650ns for 64B packets
  • ​Deep Buffering: 64MB per port for burst absorption

S5735-L (Efficiency-Focused):

  • ​Huawei Solar 2.0 ASIC: 4.8Tbps with 35% lower power draw
  • ​Store-and-Forward: 1.2μs latency with full inspection
  • ​Smart Cache: 16MB adaptive memory allocation

A financial trading firm achieved 0.0001% packet loss during market opens using S5735-S, while a smart factory reduced energy costs by 28% with S5735-L’s power-aware scheduling.

​Energy Efficiency Metrics

Power Consumption Comparison (Full Load):

​Model 10G Ports PoE Budget Idle Power Peak Efficiency
S5735-S 48 N/A 78W 0.8W/Gbps
S5735-L 24 2160W 112W 1.2W/Gbps

Huawei’s Power Monitoring Engine in S5735-L enables:

python
def adaptive_power_management():  
    monitor_poe_usage()  
    adjust_serdes_voltage()  
    if port_unused > 300s:  
        activate_energy_saving_mode()

Resulting in 42% lower TCO over 5 years compared to legacy switches.
