High-Density Scalable Load Balancer(HDSLB) is a high performance server-based Layer-4 load balancer.
HDSLB leverages several key performance optimziation techniques of Intel's hardwares to achieve scalable performance.
HDSLB is based on DPVS.
Rough Performance data on recent Intel's Xeon CPU (e.g. 3rd & 4th generation) and NIC (E810 100G) based server：
- Concurrent Session: 100M level / Node
- Throughput: > 8Mpps / Core @FNAT
- TCP Session Est. Rate > 800K / Core
- Linear growth
