Abstract

fetched live from OpenAlex

Today, many have attempted to provide multimedia services using IP over Satellite communication infrastructure. The traffic complexity and real-time constraints of the multimedia services pose challenges to guarantee the delivery of packets end-to-end. This challenge is enhanced when we take the network dynamics into account. At present, Quality of Service (QoS) in the router’s forwarding plane provides traffic differentiation capability in the traditional terrestrial networks. While the same QoS concepts can be borrowed and implemented in the ground terminals, the satellites presently do not have the capability to understand and respect the packet differentiation done by ground terminals and carry forward that differentiation end-to-end. Hence networks with QoS implementation only in Ground terminals presently exist. In this paper, we will clearly show that partial implementation of QoS in a satellite based network cannot provide multimedia service guarantee. To solve this, we introduce a concept for satellite-based networks, namely Hierarchical QoS (H-QoS), and evaluate the multimedia traffic performance on satellitebased networks with and without H-QoS. We will clearly show that with H-QoS, we achieve better multimedia throughput. In addition, we will provide compelling reasons with performance evidence that future satellites be designed with advanced QoS features and control feedback mechanisms, to support end-to-end multimedia traffic with service guarantees. In addition, we show that H-QoS with feedback mechanism only satisfies the necessary condition to achieve end-to-end performance guarantees. We show that H-QoS in conjunction with Traffic Engineering in Inter Satellite Routing Protocol clearly provides end-to-end multimedia traffic differentiation and hence guarantees performance.

Teacher imitation

Not 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.
