Holo's main goal is to create a reliable, easy-to-maintain, and extensible codebase. With the ever increasing complexity of routing protocols and their extensions, it's crucial to have routing protocol implementations built on a robust foundation. To that end, Holo's codebase prioritizes simplicity, modularity, and thorough documentation. Thanks to the strictness of the Rust compiler and extensive unit tests, it's expected that most regressions will be caught early in the development cycle of new features.
Holo was developed specifically for high-scale, automation-driven networks that require programmable configuration and monitoring using structured and modeled data. Holo natively implements standard YANG modules from IETF and supports multiple management interfaces, including native gRPC and gNMI. Additionally, Holo features a standalone CLI that dynamically renders commands from YANG modules and communicates with the Holo daemon through gRPC.
The changes made to the configuration are processed as transactions, guaranteeing that either all the changes are applied or none at all. This feature is a significant facilitator of network automation as it eliminates the need for error recovery in management applications. Holo also supports network-wide transactions involving multiple network devices. Additional network automation capabilities include confirmed commits and configuration rollback support.
