Xinertel DarYu-X Series High-Performance Layer 2–7 Network Test Platform

Overview

The Xinertel DarYu-X Series High-Performance Layer 2–7 Network Test Platform is an enterprise-grade, modular network testing infrastructure engineered for validation and benchmarking of high-end networking equipment—including core routers, data center switches, SDN/NFV gateways, and application-layer security appliances. Built on a deterministic, FPGA-accelerated architecture, the platform implements line-rate traffic generation, real-time packet capture, and protocol state machine emulation across OSI Layers 2 through 7. Its design adheres to RFC-compliant forwarding semantics and supports full-stack conformance testing under sustained load conditions—enabling R&D labs, interoperability test centers, and QA teams to validate device behavior under realistic scale, concurrency, and protocol complexity. The system operates in both standalone chassis mode and multi-chassis synchronized configurations, supporting time-synchronized distributed testing across geographically dispersed testbeds.

Key Features

• Modular chassis architecture: DarYu3000 (3-slot) and DarYu12000 (12-slot) variants support hot-swappable X-series interface modules, enabling flexible capacity scaling without service interruption.
• Comprehensive port density and speed coverage: Up to 48 x 400GbE ports per 12-slot chassis; native support for 400G/100G/40G/25G/10G/5G/2.5G/1G Ethernet interfaces—both optical and electrical—with auto-negotiation and FEC configuration.
• FPGA-based wire-speed processing: Full-duplex, zero-drop traffic generation and latency-sensitive packet capture at line rate, with sub-microsecond timestamp resolution and hardware-accelerated flow classification.
• Advanced routing scalability: Per-port support for up to 4 million discrete IPv4/IPv6 route entries; concurrent BGP4, OSPFv2/v3, IS-IS, and PIM-SM/SSM session emulation with route flapping and convergence timing analysis.
• Multi-protocol performance stress testing: Native support for MPLS L2/L3 VPNs, VXLAN/EVPN control plane verification, Segment Routing (SR-MPLS & SRv6), IGMP/MLD snooping, and DHCPv4/v6 relay stress scenarios.
• Dual-software ecosystem: Integrated compatibility with RENIX (Layer 2–4 functional & performance test suite) and ALPS (Layer 4–7 application-aware traffic simulation platform), both built on a unified PCT (Protocol Control and Traffic) architecture.

Sample Compatibility & Compliance

The DarYu-X platform is validated against industry-standard test methodologies defined in IETF RFCs (e.g., RFC 2544, RFC 2889, RFC 3918, RFC 6815), ITU-T Y.1564, and IEEE 802.1Q, 802.1ad, and 802.3 standards. It supports compliance workflows required for carrier-grade equipment certification (e.g., MEF CE 2.0, ETSI NFV MANO), as well as security evaluation frameworks including Common Criteria (ISO/IEC 15408) and NIST SP 800-126 for network device assurance. All test reports generated by RENIX and ALPS include audit-ready metadata—timestamped logs, configuration snapshots, and cryptographic hash signatures—ensuring traceability for ISO/IEC 17025-accredited laboratories and GLP/GMP-aligned validation environments.

Software & Data Management

RENIX provides CLI- and GUI-driven Layer 2–4 test orchestration, supporting RFC 2544 throughput/latency/frame-loss benchmarking, back-to-back frame testing, and burst tolerance analysis. ALPS delivers web-native, role-based access to Layer 4–7 test automation: it enables scalable client-server session modeling (HTTP/HTTPS, TLS 1.2/1.3, SIP, RTP, DNS, SMTP), behavioral fidelity via TCP stack emulation, and malicious traffic injection (e.g., HTTP fuzzing, DNS amplification, TLS handshake exhaustion). Both applications store test artifacts in a PostgreSQL-backed repository with RESTful API exposure, supporting CI/CD pipeline integration (Jenkins, GitLab CI), automated report generation (PDF/XML/CSV), and long-term trend analytics via time-series indexing. Audit trails comply with FDA 21 CFR Part 11 requirements for electronic records and signatures.

Applications

• R&D validation of next-generation data center fabrics (e.g., CLOS topologies, RoCEv2 congestion control, NVMe over Fabrics).
• Security appliance benchmarking: firewall rule-set scalability, IPS signature matching latency, WAF SQLi/XSS evasion resistance, DPI deep packet inspection throughput under encrypted traffic loads.
• 5G transport and core network testing: UPF performance under massive UE session churn, SMF control-plane stress with concurrent PDU session establishment, and time-sensitive networking (TSN) coexistence validation.
• Cloud-native infrastructure testing: Kubernetes CNI plugin verification, service mesh (Istio/Linkerd) sidecar proxy latency, and eBPF-based observability agent impact assessment.
• Interoperability certification: MEF-certified CE services, ONF-defined AWMF test suites, and Open Compute Project (OCP) switch compliance verification.

FAQ

What is the maximum number of concurrent L4–7 sessions supported by ALPS on a fully populated DarYu12000 chassis?
ALPS scales linearly with installed interface capacity and host memory; typical deployments achieve 10–15 million concurrent TCP/UDP sessions per 12-slot chassis when configured with 16 x 100G modules and 512 GB RAM.
Does the DarYu-X platform support hardware timestamping for precise latency measurement?
Yes—each X-series module integrates IEEE 1588v2 PTP Grandmaster/Slave capability and supports hardware-assisted timestamping at ingress/egress with ≤50 ns precision, traceable to UTC via GPS or PTP boundary clocks.
Can RENIX and ALPS be operated simultaneously on the same chassis?
Yes—RENIX and ALPS operate as independent, containerized services on the same management controller, enabling concurrent Layer 2–4 functional tests and Layer 4–7 application-layer stress tests without resource contention.
Is third-party test script integration supported?
Both RENIX and ALPS expose comprehensive Python SDKs and REST APIs, enabling integration with Robot Framework, PyTest, and custom CI/CD orchestrators for automated regression and nightly validation pipelines.
What documentation and training resources are provided with the platform?
Xinertel delivers ISO 9001-aligned installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) documentation packages, along with instructor-led remote training, hands-on lab exercises, and annual software update subscriptions with technical support SLAs.
