The wireless edge router: A network processor-based packet data serving node for a CDMA2000* network
Bibliographic record
Abstract
A network processing unit (NPU) is increasingly becoming the processor of choice for building custom packet-processing gateways. In this paper, we present an NPU-based design and architecture for a packet data serving node (PDSN) in a CDMA2000∗network. A PDSN is a packet-processing gateway that interfaces between the Internet and the wireless radio access network to provide packet data services to mobile users. We map the different functions of the PDSN onto the packet-processing engines and the core processor of an NPU. This involves a complete separation of the control plane, which is implemented in the core processor, and the data plane, which is implemented using a multistage packet pipeline mapped onto the packet-processing engines. We describe resource allocation schemes for packet buffering and processing and also a flexible communication method with the core processor. The mechanisms described in the paper are general enough to be used to implement other NPU-based packet-processing gateways. We also present a prototype implementation of the PDSN on an NPU and show its superiority to commercial products by means of measurement experiments.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
