JANUS: Design of a software-defined infrastructure manager and its network control architecture
Bibliographic record
Abstract
We present an integrated management architecture based on Software-Defined Infrastructure (SDI), an approach where an SDI Manager controls heterogeneous resources with a global view of the entire infrastructure. By exposing APIs on top of our SDI management system, we create a programmatic cloud environment where users can innovate, creating unique applications and services in a software-defined manner. In this paper we first provide an overview of the SDI manager, dubbed JANUS, that was developed and implemented in the SAVI testbed for application platforms. We focus on advanced software-defined network services that can be provided in this SDI environment. We present requirements that must be met by the SDI management system: Pro-active rule installation; Broadcast-free networking; VN creation and management; scalability and extensibility; and support for legacy networks. We describe the Network Control Module of the JANUS SDI Manager which was designed to meet the specified requirements. A key innovation that promotes scalability and performance is a FlowStore that tracks flows and cache rules in the SDN network.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
