SET: a Simple and Effective Technique to improve cost efficiency of VNF placement and chaining algorithms for network service provisioning
Bibliographic record
Abstract
Network Functions Virtualization (NFV) is a promising solution to provide cost-efficient, scalable and rapid deployment of network services. It allows the implementation of fine-grained services as a chain of Virtual Network Functions (VNFs). In order to place the VNF chains in the network, several cost-efficient methods have been already proposed. However, a few works have considered order of VNFs to reduce the cost. In this paper, we propose a Simple and Effective Technique (SET), which can be easily combined with VNF placement methods to dramatically improve their cost efficiency by considering different possible orders for the VNFs in the chain. As a proof-of-concept, we combine the proposed technique with one of the recent cost-efficient VNF placement and chaining algorithms called CCVP. The results show that the combination can yield significantly better cost than CCVP operating solo.

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.
