GNN-GM: A Proactive Caching Scheme for Named Data Networking
Bibliographic record
Abstract
As people spend more time watching movies and sharing videos online, it is crucial to provide users with a satisfactory quality of experience (QoE). With the help of the in-network caching feature in named data networking (NDN), our paper aims to improve user experience through caching. We propose a graph neural network-gain maximization (GNN-GM) cache placement algorithm. First, we use a GNN model to predict users’ ratings of unviewed videos. Second, we consider the total predicted rating of a video as the gain of caching the video. Third, we propose a cache placement algorithm to maximize the caching gains and proactively cache videos. We also design a caching replacement strategy based on the gain of caching the video. We utilize a real-world dataset to evaluate our caching strategy. Compared to state-of-the-art caching approaches, experimental results show that our caching policy improves cache hit rate by 25%, reduces latency by 5%, and reduces server load by 7%.

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.
