Why
Critical networks must remain available across constrained, complex, distributed and changing paths. 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.
Topology
How
Model primary networks, satellite, microwave/wireless, site links, emergency vehicles, portable nodes, data center/cloud entries, security boundaries and servers. Define delay, loss, jitter, throughput, recovery and degradation requirements for voice, video, command apps, files, sensors, logs and encryption.
Apply high delay, low bandwidth, burst loss, jitter, reordering, outages and reductions at different segments. Build satellite, constrained, air-ground, shore-ship, remote-site and temporary emergency profiles.
Generate multi-stream backgrounds, bursts and intersite loads or replay Ethernet PCAPs, protocol and security samples. Use separate devices for simultaneous modes; real endpoints provide full interactions.
Progressively degrade Primary, Alternate, Contingency and Emergency paths. Check switching, minimum service, voice/video/control protection and lower-priority degradation. BestPerf records quality, Traffic Generation supplies load and ChaosBridge supplies repeatable conditions.
Flow Hunter observes sessions, DNS/TLS/HTTP/SIP/RTP, QoS, retries, failures and captures at critical links and security boundaries. Combine curves, parameters, sessions, PCAPs and logs into acceptance, vendor-review and exercise reports.

Core Emulation Equipment
Optional Supporting Tools
NetAccura Traffic Generation
Generate L2-L3 test streams. Software models also replay Ethernet PCAPs, rewrite IPv4 addresses and TCP/UDP ports, and multiply traffic for performance, security detection and issue reproduction. Stop all transmit tasks before switching modes. Simultaneous generation and replay require separate devices.
BestPerf
Actively measure RTT, directional loss, jitter, micro-outages, TCP goodput and quality under load to establish link baselines.
Flow Hunter
Capture passively through mirrored ports or TAPs for L2-L7 analysis, session investigation, protocol-stage diagnosis and PCAP export.
Result
Make DDIL concrete through configurable, repeatable delay, loss, jitter, bandwidth, outage and multihop profiles, with availability evidence for each service.
Trigger, observe and retest each path to verify switching, QoS, degradation and recovery requirements.
Combine legitimate traffic, load, impairments, attack samples, appliances and passive evidence to assess policies, performance and detection limits.
Deliver more than throughput or delay figures: include topology, parameters, timelines, quality curves, key sessions, anomalies, PCAP extracts and retest results. Development, testing, operations, vendors and customers can discuss the same evidence rather than relying on screenshots, verbal descriptions and repeated debate.
