"Experimental Dataset for Edge-Native Transport Relocation in HFC Access Networks"

"# Dataset: Edge-Native Performance Scenarios in HFC Access Networks This dataset supports the evaluation of an edge-native full-stack architecture for Hybrid Fiber-Coaxial (HFC) networks, focused on relocating L2\u2013L4 transport processing from a centralized vCMTS to Multi-access Edge Computing (MEC) nodes using the VPP HostStack. It complements the research article:> Ivan Ivanets et al., \u201cAn Edge-Native Full-Stack Architecture for Hybrid Fiber-Coaxial Networks,\u201d submitted to IEEE Communications Magazine, Special Issue on Network Softwarization and Management, 2025. ## DOI https:\/\/doi.org\/10.6084\/m9.figshare.29036366 --- ## Evaluated Scenarios | Scenario | MEC Stack                         | vCMTS Stack                     | Description                                       ||----------|-----------------------------------|----------------------------------|---------------------------------------------------|| S1       | Linux Kernel TCP                  | Linux Kernel TCP                | Baseline DOCSIS 3.1 setup                         || S2       | VPP HostStack (via `LD_PRELOAD`)  | Linux Kernel TCP                | Partial stack relocation (MEC client)            || S3       | VPP HostStack (via `LD_PRELOAD`)  | VPP HostStack (via `LD_PRELOAD`)| Full user-space stack on both sides              | All scenarios were run on the 3-node `lf_3n_icx_testbed38` using 25GE interfaces on port7\/8 (Intel XXV710), and reproducible CSIT jobs were triggered via Jenkins CI using [FD.io infrastructure](https:\/\/csit.fd.io). --- ## Tools & Methods - Traffic Generator: `iperf3` with dynamic linking via `LD_PRELOAD`- Metrics Collected:  - TCP throughput (Gbps)  - Retransmissions (%)  - CPU usage (%)  - Standard deviation (stability)- Runtime: 20s runs with `--parallel 1`- Automation: Robot Framework + Jenkins + OpenTelemetry --- ## Example Metrics (Scenario S3 \u2013 Symmetric VPP HostStack) Test ID:  `tests.vpp.perf.hoststack.25ge2p1xxv710-eth-ip4tcp-hfc-scenarios-ldpreload-1cl1s-bps.1460b-1c-eth-ip4tcp-hfc-scenarios-ldpreload-1cl1s-bps` Extracted from `1460b-1c-eth-ip4tcp-hfc-scenarios-ldpreload-1cl1s-bps.info.json`: - **Test duration:** 20.0 seconds- **Measured throughput:** **12.53 Gbps**- **TCP retransmissions:** 0- **LD_PRELOAD:** enabled- **NIC:** Intel XXV710, port1 (25GE), `vfio-pci` driver- **Topology:** 3-node single link (direct)- **VPP version:** `25.06-rc0~218-g0352899c0~b503`- **Client\/Streams:** 1 client, 1 stream- **Status:** passed --- ## Notes - This study focuses on **L2\u2013L4 transport relocation**. Application-layer (L5) softwarization remains **out of scope** and will be addressed in future research.- All results are reproducible via patch-based test execution in [Gerrit](https:\/\/gerrit.fd.io\/r\/c\/csit) using CI jobs. --- ## License This dataset is made available under the [Apache License, Version 2.0](https:\/\/www.apache.org\/licenses\/LICENSE-2.0.html). --- ## Citation If you use this dataset, please cite: > Ivan Ivanets et al., \u201cEdge-Native Performance Scenarios in HFC Access Networks,\u201d Figshare, 2025.
