SNE Ignite

実際の 5G トランスポートネットワークモデルを用いた新しい自動テストに対応。
6.8 µs の本質的に低いレイテンシを備えた 100 GbE フルラインレートのネットワークエミュレーターは、5G O‑RAN の O‑DU から O‑RU、O‑DU から O‑CU(フロントホールおよびミッドホール)間のベンダー相互接続性テストなど、高精度アプリケーション向けに設計されています。O‑RAN WG4 および WG5 のレイテンシ仕様への準拠を確保し、オペレーターのネットワーク ROI を最適化します。
SNE Ignite は、高容量データセンター間接続(DCI)設計の検証にも最適です。
設計全体を構築してから、導入後に予期しない挙動が発覚するのはコスト効率が良くありません。実際のネットワーク条件(輻輳やインターフェース障害を含む)下で最高利用率でも確実に動作することを、導入前に検証する必要があります。
このような特性評価には、SNE Ignite の豊富なインペアメント機能とマップ機能が最適であり、ネットワークベンダー選定フェーズのラボ環境や実運用に近い状況で、定義済みのネットワークシナリオを忠実かつ再現性高く生成できます。

Validate O-RAN interoperability

Using the SNE Ignite’s extensive packet and protocol impairments, the minimum and maximum latency performance to O-RAN’s T12_max/T34_max specifications can be validated in multi-vendor deployments. Multi-vendor O-RAN deployments eliminate vendor lock-in, but non O-RAN standards-compliant interoperation between components has a monetary cost to the operator because of the impact on network efficiency.

SNE Ignite is able to perform these O-RAN standards-driven validations with orchestrated impairments at the full line-rates of 100 GbE, 25 GbE or 10 GbE, along with transparent passing of PTP (IEEE1588v2) or SyncE (ITU-T G.8261, G.8262, G.8264 and G.781) signaling, essential for performing the tests.

PTP Transparent Clock (TC)

A network emulator with transparent clock functionality is essential for impairment testing in a time-synchronized environment. For PTP (RFC1588v2), this eliminates noise and ensures high priority S-plane traffic is not affected by large U-plane packets e.g. jumbo.

  • Minimal Packet Delay Variation (PDV).
  • Improves test repeatability.
  • Maintains timing integrity upstream/downstream during impairment testing.

Synchronous Ethernet (SyncE) passthrough

Synchronous Ethernet (SyncE) passthrough ensures physical-layer frequency synchronization is preserved through the network emulator, enabling accurate and representative testing in time-sensitive networks.

  • Enables precise validation of SyncE-dependent applications and network devices.
  • Preserves physical clock continuity end-to-end.

Low intrinsic latency and minimal PDV

O-RAN fronthaul links (O-DU to O-RU) cannot be tested to O-RAN interoperability standards specifications unless the network emulator has an in-line latency of below 8 μs. SNE Ignite outperforms this with an intrinsic latency of just 6.8 μs, the first network emulator on the market with this level of performance.

SNE Ignite's user interface (UI) leverages the SNE's graphical map-based Web UI

  • Drag and drop from the extensive list of impairments into your network “map” to create specific impairment scenarios to meet your testing needs.
  • Take full control by linking together impairments in the order required and directly controlling the flow of packets around the simulated network.

SNE Ignite introduces precise, programmable network impairments into Ethernet traffic to emulate real-world conditions

Delay

Latency testing is critical for validating time-sensitive applications like 5G O-RAN fronthaul, where even microsecond-level delays can impact synchronization and throughput.
  • Supports delay injection up to 3200 ms on 10 GbE and 320 ms on 100 GbE interfaces.
  • Delay can be configured per flow using powerful filtering (e.g. MAC, VLAN, MPLS).
  • Nanosecond-level accuracy ensures repeatable and deterministic testing.

Packet Loss

As few real-world networks are packet perfect, packet loss emulation is used to test application resilience and error recovery mechanisms under degraded network conditions.
  • Supports both random and deterministic packet drops.
  • Can be configured per flow using user defined filters.
  • Used in SLA verification, RFC2544, Y.1564, and Y.1731 testing scenarios.

Jitter

Jitter simulates the variation in packet arrival times, which is especially disruptive in real time services such as voice, video, and synchronized radio units.
  • Supports PDV injection with nanosecond granularity.
  • Jitter profiles can be applied independently per flow.
  • FPGA-based architecture ensures best-in-class intrinsic jitter (as low as 0.1 μs).

Packet re-ordering

Reordering simulates out-of-order delivery, which is critical for validating and characterizing packet reassembly behaviours.
  • AI workloads.
  • TCP reassembly stress testing.
  • Load-balanced path emulation.

Errored packets

SNE Ignite supports frame-level error injection, enabling the simulation of bit-level corruption for OAM testing and protocol robustness validation.
  • OAM testing.
  • BER validation.
  • Protocol resilience testing.

Duplication

Duplication emulates scenarios where packets are duplicated due to retransmissions or network loops.
  • Application-layer deduplication testing.
  • Network loop simulation.
  • Resilience validation.

Applications

  • O-RAN fronthaul (O-DU to O-RU) and midhaul (O-CU to O-DU).
  • O-RAN 5G Mobile Edge Computing (MEC).
  • 5G Core and backhaul.
  • Datacenter interconnect/migration.
  • Cloud migration planning.
  • Telecom/Federal applications.
  • Defense applications.
  • Customer Proof of Concept (PoC).
  • SLA verification.
  • IPTV, video.
