Overview
Explains ULB features and configuration for technical implementation and operations. It covers resilience and traffic convergence via BGP and BFD, neighbor discovery, core dump generation, and service outbound route (SOR).
The ULB is designed to enhance network resilience, ensure rapid traffic convergence, and manage network resources effectively.
These features are currently applicable only for on-premises deployments.
Resilience and traffic convergence via BGP and BFD
Explains how resilience and traffic convergence are achieved using BGP and BFD protocols, focusing on network stability and rapid rerouting during node failures.
Neighbor discovery
Details neighbor discovery for technical implementation and operations. It covers how the neighbor discovery works, configuring the refresh interval, interfaces, and node labels, and monitoring neighbor entries.
Core dump generation
Explains how ULB enables generation of core dump files for the ULB Agent and Operator processes, including storage location and collection procedures for debugging.
Service outbound route (SOR)
Explains the Service Outbound Route (SOR) feature, including its technical implementation, operational benefits, limitations, and how SOR works within Kubernetes clusters.
Support for data path metrics based on eBPF
Explains the support for data path metrics based on eBPF, including benefits, limitations, metric collection, and enabling data path metrics collection for technical implementation and operations.
Miscellaneous configurations
Explains miscellaneous configurations for technical implementation and operations, including how to configure cilium BPF map and enable cilium hubble statistics.
