Futures Exchange - Aggregation/Distribution Microburst Buffering Solution
Addresses microburst packet loss in multi-link futures-exchange traffic convergence scenarios through traffic shaping and large-buffer design, ensuring complete traffic data for backend security analytics platforms.
Challenges
When high-bandwidth ingress ports send traffic to lower-bandwidth egress ports, microbursts can exceed output capacity. Excess traffic must be absorbed by internal buffers. Traditional TAP architectures have limited packet buffers and cannot absorb all bursts, which leads to packet loss.
Solution
- Enable traffic shaping at the access layer to smooth traffic peaks
- Allocate on-chip packet buffers with a hybrid static + dynamic strategy
- Equip each TAP with large off-chip high-speed packet buffers (32GB+, 200Gbps)
Value
Successfully resolved microburst packet loss in multi-link convergence for futures exchange traffic, enabling backend security analytics platforms (Colasoft, Qi-Anxin, Sangfor) to receive complete traffic data.
