 The service mesh software represented by Istio has gradually become popular and has become an important component of cloud infrastructure. However, the current service mesh still face some challenges:
 
 - **Extra latency overhead at the proxy layer**: Single hop service access increases by [2~3ms](https://istio.io/latest/docs/ops/deployment/performance-and-scalability/#data-plane-performance), which cannot meet the SLA requirements of latency-sensitive applications. Although the community has come up with a variety of data plane solutions to this problem, the overhead introduced by agents cannot be completely reduced.
-- **High resources occupation**: The agent occupies extra CPU/MEM overhead, and the deployment density of service container decreases.
