Download ChaosBridge API examples that use only the Python standard library. [← WAN Emulator Resources](https://www.netaccura.com/en/products/wan-emulator#product-resources) NetAccura · ChaosBridge ### Control Devices with Standard HTTP Requests HTTP + JSON, with no dedicated API SDK. Start with device discovery and configure fixed delay on the multifunction series. [API DocumentationApifox](https://68egd6dxv1.apifox.cn/) API documentation for future versions will be published here. Documentation Access Password NetAccura #### 01 Get the Device Address and API Token Create an API Token in the device's security settings. Replace YOUR_DEVICE and YOUR_API_TOKEN with the management address and token. Use the HTTP or HTTPS protocol configured on the device. The script authenticates with Authorization: Bearer. Request bodies use application/json. ``` export CHAOSBRIDGE_URL="https://YOUR_DEVICE" export CHAOSBRIDGE_TOKEN="YOUR_API_TOKEN" curl --fail-with-body \ -H "Authorization: Bearer $CHAOSBRIDGE_TOKEN" \ "$CHAOSBRIDGE_URL/api/v1/engines" ``` Check the HTTP status code and the success field. Engine queries return engine, port and capability information; use the actual identifiers in the response for subsequent operations. #### 02 Set 100 ms One-Way Delay on an Existing Link This example is for the multifunction series. Find the link ID in the target engine's virtual link list and replace YOUR_LINK_ID. The request updates only fixed delay in the A → B direction; fields not included retain their settings. ``` export LINK_ID="YOUR_LINK_ID" curl --fail-with-body -X PATCH \ "$CHAOSBRIDGE_URL/api/v1/virtual-links/$LINK_ID" \ -H "Authorization: Bearer $CHAOSBRIDGE_TOKEN" \ -H "Content-Type: application/json" \ -d '{ "config": { "direction_a_to_b": { "enabled": true, "delay": {"mode": 1, "value_ms": 100} } } }' ``` A successful PATCH confirms that the configuration request completed. Ensure filters route traffic to the link and emulation is enabled, then verify the effect through endpoint traffic and counters. FPGA models use their corresponding hardware fields; ask a technical adviser for examples. #### 03 Download the Python Connection Example Uses only Python 3 standard libraries such as urllib and json. The script queries engines and virtual links and includes timeouts, HTTP error handling and response checks. [Download the Python Example](https://www.netaccura.com/downloads/wan-emulator/chaosbridge_api_example.py) ``` python3 chaosbridge_api_example.py --url "$CHAOSBRIDGE_URL" # Use the actual engine ID from the previous response to read its virtual links python3 chaosbridge_api_example.py \ --url "$CHAOSBRIDGE_URL" --engine-id YOUR_ENGINE_ID ``` Redirect output to a JSON file to save discovery results as the starting point for your automation workflow. #### From One Request to Automated Regression Connect → Read the Target Link → Configure Network Conditions → Run Application Tests → Collect Statistics and Captures → Save Results. Build this workflow in Python, Java, JavaScript, C#, Go or any language supporting HTTP. For batch configuration, repeated tests, retries or CSV reports, share your test steps with a NetAccura technical adviser. --- ## WAN Emulator Quick-Start Guide | ChaosBridge | NetAccura https://www.netaccura.com/en/resources/wan-emulator/quick-start > Run your first NetAccura ChaosBridge test, from connecting equipment and configuring bidirectional links and filters to fixed-delay testing and result validation. [← WAN Emulator Resources](https://www.netaccura.com/en/products/wan-emulator#product-resources) NetAccura · ChaosBridge ### Run Your First Network Impairment Test Use fixed delay to learn the process from connection to validation. For the multifunction series; on FPGA models, select the available hardware engine and existing links. #### 01 Connect the Test Link Install a pair of WAN emulator test ports inline between the two endpoints. Connect the management port to the management computer's network. Test traffic passes through the test ports, while the browser provides management access. Use the management address in the delivery documentation and your configured account. Confirm both test ports are Link Up and ingress RX counters increase with test traffic. #### 02 Select the Engine, Port Pair and Emulation Mode Select the engine and port pair on the dashboard. A → B receives on Port A and transmits on Port B; B → A is the reverse. Select Emulation mode to apply impairments. Check connectivity without impairments first. Record RTT, throughput or application behavior as the baseline. #### 03 Create a Link and Match Test Traffic On the multifunction series, select New Link and name it. FPGA engines use existing hardware links. Add rules to both ingress filters to route test traffic to the target link. For an isolated first test, select All Traffic; add IP, port or protocol conditions when testing a specific service. Filters determine whether traffic enters the target link. After saving parameters, confirm that the link's packet counters are increasing. #### 04 Configure Fixed Delay - Open link configuration and enable delay for A → B. - Select Fixed; on the FPGA interface, select Constant. - Set the unit to ms, enter 100 and apply. - For a symmetric link, configure the same 100 ms delay for B → A. A 100 ms delay in one direction adds approximately 100 ms to baseline RTT. With 100 ms in both directions, RTT increases by approximately 200 ms. #### 05 Validate, Save and Retest Send the same traffic again and compare RTT, application response and counters before and after configuration. Use captures before and after impairments alongside application logs to investigate differences. Record the port pair, filters, bidirectional parameters and results. Save the configuration for future tests. When finished, disable the test impairments or restore the initial saved configuration. #### What Next? - Add loss, jitter and bandwidth limits to observe service recovery. - Orchestrate conditions into multiple stages and repeat them with scenario replay. - Use [RESTful API Examples](https://www.netaccura.com/en/resources/wan-emulator/api-examples) to read capabilities, configure links and organize results. --- ## Link Quality Monitoring and SLA Baselines | NetAccura https://www.netaccura.com/en/solutions/quality-assurance > Use BestPerf for RTT, directional loss, jitter, micro-outage and TCP goodput measurements, and Flow Hunter for live monitoring, session analysis, retrospe… [Back to All Solutions](https://www.netaccura.com/en/solutions) Solution Detail ### Link Quality Monitoring and SLA Baselines BestPerf Network Quality Measurement + Flow Hunter Network Traffic Analysis Turn subjective reports of slowness into trackable quality baselines.

RFC 6349 notes that L2/L3 tests alone do not fully represent end-user experience: TCP throughput also depends on RTT, bottleneck bandwidth, buffers, loss and windows. Acceptance and routine checks should therefore assess consistent application quality, not just provisioned bandwidth. BestPerf actively probes and schedules measurements without waiting for user complaints. It records RTT, directional loss, jitter, micro-outages, TCP goodput and quality under load. Flow Hunter can remain passively connected to critical links for SLA monitoring, session anomalies, protocol-stage observations and retrospective analysis, linking trends to real sessions.

Average interface utilization can hide minute-scale bursts, directional imbalance, five-minute peaks, busy-hour 95th percentiles and actual traffic sources. Bandwidth monitoring must also align ingress and egress at CE/PE handoffs, enterprise and carrier billing methods, cloud/data center directional bottlenecks, QoS treatment and backup schedules. Correlate bandwidth curves, sessions, application classes and active capacity measurements to answer these questions. Flow Hunter continuously observes real traffic and identifies top applications, hosts, sessions, protocols, VLANs, subnets, bursts and causes. BestPerf schedules available-capacity, TCP goodput and load-quality tests. Together they explain high utilization by direction, time, application, capacity threshold and expansion trigger.

MPLS often carries critical traffic; broadband and LTE/5G add capacity, internet access or backup; satellite and cloud paths introduce delay and variability. Tunnel establishment alone cannot establish reliable routing, QoS, failover or experience. MEF 70.2 defines externally visible SD-WAN service behavior through attributes and a framework. Test SD-WAN edges, controllers, CPE, Underlay Connectivity Services, Tunnel Virtual Connections, applications, policies and quality goals together, rather than single-link throughput alone. Use for vendor R&D, enterprise bakeoffs, managed SD-WAN delivery, branch rollout, SASE/security integration and cloud-edge optimization. Turn claims about intelligent routing, application assurance, failover, economical links and secure access into repeatable, measurable evidence.

Formerly local traffic may traverse dedicated circuits, VPN, SD-WAN, the internet, regional backbones or VPC/VNet boundaries. Bandwidth, delay, jitter, loss and detours affect cutover windows and performance. Bulk transfers, object storage, replication and regional synchronization are network-sensitive. Limited bandwidth lengthens migration; delay reduces TCP goodput; loss and micro-outages cause retries, failures and timeouts. Problems may emerge only when migration scale, user concurrency and actual cloud paths combine, threatening windows, rollback and experience. Establish a baseline, reproduce target cloud paths in the lab, and test migration and application access under varied conditions. Monitor during and after migration, then compare results to answer: what is the current baseline, can target paths carry the workload, and is performance maintained?

Captures used only as attachments leave developers guessing from logs; repeatable lab replay turns them into inputs for reproduction and regression. Common challenges include intermittent customer failures absent in the lab, protocol upgrades breaking older scenarios, no identical traffic for A/B fix checks, and releases tested only with synthetic loads. PCAP replay addresses these gaps. Flow Hunter extracts PCAPs and context around abnormal sessions, protocol stages, hosts and time windows. NetAccura Traffic Generation replays original timing or configured rates with optional IPv4/port rewriting and multiplication. ChaosBridge reproduces link conditions. Simultaneous generated background traffic requires another device; dynamic handshakes, authentication and responses require real endpoints.

A brief stall may involve wireless switching, upstream congestion, RTP loss, RTCP feedback, SIP/SDP negotiation, TURN/media relay changes or server limits. RTP/RTCP in RFC 3550 provides transport, timestamps, sequence numbers and quality feedback. SDP in RFC 8866 describes sessions, while WebRTC standardizes real-time media/data. Tests must examine media, signaling, networks and QoE together, not bandwidth alone. For conferencing, classes, telemedicine, live interaction, dispatch, contact centers, cloud meetings and RTC SDKs.

Following Apposite's satellite testing approach, labs should assess full-path throughput, delay, loss, response and QoS, while isolating individual VSATs, modems, proxies and gateways to locate bottlenecks. 3GPP NTN covers satellites, HAPS and UAS; LEO/MEO/GEO differ in delay, coverage and handover. Satellite services mix voice, video, web, files, telemetry, command applications, IoT, maintenance and tunnels. Use real workloads and background load beyond ping or one iperf stream.

RoCE v2 runs over UDP/IPv4/IPv6, commonly destination port 4791. Microbursts, loss, PFC storms, ECN thresholds and QoS affect GPU training, storage and HPC efficiency and tail latency. R&D validation deliberately creates failure and boundary conditions for NICs, switches, AI fabrics and storage networks. Deployment, delivery and change acceptance instead confirm that an existing network meets agreed requirements. Ping and iperf alone miss RoCE issues. Use ChaosBridge for loss, jitter, bandwidth reduction, micro-outages and link failures, alongside east-west load, bursts, queue congestion, PFC/ECN and low-delay path changes.

Satellite, air-ground, shore-ship, private intersite, emergency vehicles, portable nodes, temporary command sites, backhaul, video, dispatch and encrypted apps face delay, low bandwidth, bursts, intermittent links, multihop paths and security policies. DDIL means denied, degraded, intermittent and limited communications. PACE defines Primary, Alternate, Contingency and Emergency plans. Validate that each path carries critical services under impairments; controlled lab conditions cover combinations that costly field exercises cannot repeat reliably. These tests support cyber ranges, selection, acceptance and integration. Ranges need legitimate traffic, load, QoS, impairments and evidence as well as attack samples. Selection should measure real behavior on constrained multihop networks. Scope remains general engineering, reliability and security validation, not sensitive missions or restricted topologies.

[← Technical Support · Troubleshooting](https://www.netaccura.com/en/support#troubleshooting) NetAccura · ChaosBridge ### Cannot Open the Management Page For problems opening the WAN emulator Web interface, first check management connectivity, then the address and access path. #### 01 Confirm You Are Using the Management Port The management computer accesses the Web page through the management port. Test ports carry test traffic; their activity does not establish Web-management availability. Check the management cable and both endpoints. If a switch is present, check its corresponding port too. #### 02 Use the Actual Management Address Find the IP, port and HTTP/HTTPS scheme in delivery records or saved configuration. Do not assume another device's default address. Check the computer's IP, subnet mask and routes. For cross-subnet access, verify the gateway and management network can reach the device. #### 03 Distinguish Network and Browser Issues Record whether the browser reports a timeout, refused connection or certificate error; each requires different checks. Ping can help check reachability, but no ping response alone does not prove the Web service is unavailable. Confirm the scheme and port, and check proxy/VPN routing. For certificate warnings, verify device identity and certificate configuration first; do not simply disable certificate checks. #### Need More Help? Have the following information ready when contacting an adviser: Device model, software version if known, management address, computer subnet, connection method and browser error screenshot.

Check in this order before changing parameters repeatedly. #### 01 Establish an Unimpaired Baseline Save the current configuration. Once other tests will not be affected, use the same endpoints and traffic without impairments to record RTT or response time. Confirm traffic passes inline through the emulator rather than another path. #### 02 Check Engine, Port Pair and Traffic Matching Select the physically connected engine/port pair and Emulation mode. Check that ingress filters route this traffic to the target virtual link. Send traffic and confirm target-link counters increase. If ports show traffic but the link does not, inspect matching rules first. #### 03 Check Direction, Units and Enable State A → B and B → A are independent. Enable delay in the intended direction, select ms and apply the settings. Start with a clear 100 ms fixed-delay comparison. Select Fixed on multifunction models or Constant on FPGA models. #### 04 Interpret Results along the Round-Trip Path If requests and responses use the same port pair, 100 ms in one direction adds about 100 ms to baseline RTT; 100 ms in each direction adds about 200 ms. Repeat and compare with baseline. Investigate remaining differences using counters, before/after captures and logs to verify direction and path. Restore the original configuration afterward. #### Need More Help?

If ingress is empty, inspect the sender, cables/optics, port speed and upstream switching. #### 02 Compare Rules with Actual Packets Check actual MAC, VLAN, IP, port and protocol values against filters, and verify the target link. Check reverse-direction ingress rules too. For encapsulated traffic, confirm the matched header layer. In an isolated test, temporarily use All Traffic to rule out filters, then restore the original rules. #### 03 Compare Counter Deltas over the Same Interval Record initial/final ingress RX, target-link, egress TX and receiver counters and compare deltas over one interval. Ingress without link increments points to matching. Link increments without receiver traffic call for checks of loss, bandwidth, queues, egress connectivity and the receiver. Use captures at relevant processing points for deeper diagnosis. A link name or successful save alone does not prove traffic enters the link. #### Need More Help? Have the following information ready when contacting an adviser: Topology, traffic characteristics, filters, target link and counter deltas at every stage over the same interval.

Handle timeouts, certificate failures and HTTP authentication errors separately. [← Technical Support · Troubleshooting](https://www.netaccura.com/en/support#troubleshooting) NetAccura · ChaosBridge ### API Authentication Fails Confirm the request reaches the right device, then check authentication and permissions. Handle timeouts, certificate failures and HTTP authentication errors separately. #### 01 Confirm the Actual Request Address Check management address, scheme and port; replace YOUR_DEVICE. Query /api/v1/engines to check connectivity and authentication. For timeouts or certificate errors, resolve the network/certificate issue before changing tokens repeatedly. #### 02 Check the Bearer Token Header Obtain an authorized API Token from the device's security settings. Use Authorization: Bearer followed by one space and the actual token. Confirm the environment variable is set and contains no newlines, extra quotes or example placeholders. Do not put tokens in public links or URL query parameters. #### 03 Use Status Codes and Responses to Diagnose 401 usually means valid authentication is missing: check correctness, expiry or revocation. 403 usually means access is forbidden: check account/token permissions and the response details. For 404, check the API path and software version. Not every unsuccessful response is an authentication failure. After HTTP success, check the response's success field. For configuration changes, also verify the effect using traffic and counters. #### Need More Help? Have the following information ready when contacting an adviser: Software version, request method/path, HTTP status and error response. Remove tokens, passwords and other credentials before sharing logs or screenshots.
