AI Technical Summary
In Kubernetes clusters, the combination of node-local DNS service and kernel service for domain name resolution results in significant performance overhead, especially when the number of domain name resolution requests is high, leading to noticeable latency.
By leveraging the programmability of the eBPF kernel and storing Socket information using a Map structure, domain name resolution requests can be directly redirected at the Socket layer, bypassing the TCP/IP protocol stack. This allows requests to be redirected directly to container groups with local resolution capabilities at the Socket layer, reducing performance overhead.
It improves the speed of domain name resolution between Pods within the same node in the Kubernetes cluster, reduces the performance consumption of the node, and improves the efficiency of domain name resolution.
