Historical Packet Analysis
Historical packet analysis is the process of analyzing previously captured network traffic to investigate intermittent issues, validate timelines, and reconstruct past events.
I
IT Visibility
The ability for IT teams to monitor and understand performance across the entire digital environment—from endpoint to cloud.
J
Jitter
Jitter is the variation in packet arrival times across a network, commonly affecting voice and video quality.
L
Latency
Latency is the delay experienced as data travels across a network from source to destination.
Latency
The delay between a user action and system response—one of the most critical factors impacting user experience.
M
Mean Time to Resolution (MTTR)
The average time it takes for IT teams to diagnose and resolve an issue.
N
Network Analyzer
A network analyzer is a platform or tool used to monitor, capture, and analyze network traffic for troubleshooting, diagnostics, and operational visibility.
Network Forensics
Network forensics is the investigation and reconstruction of network activity using packet captures, traffic analysis, and historical data to understand security or operational incidents.
Network Performance
The speed, latency, and reliability of network connections supporting user access to applications and services.
Network Performance Monitoring & Diagnostics (NPMD)
Network Performance Monitoring & Diagnostics (NPMD) is a packet-based approach to monitoring and troubleshooting network and application performance using real-time and historical traffic analysis.
Network Traffic Analysis
Network traffic analysis is the process of monitoring and analyzing network communication patterns, bandwidth usage, latency, retransmissions, and traffic behavior across an environment.
P
Packet Analysis
Packet analysis is the inspection and interpretation of network packets to understand application behavior, diagnose performance issues, investigate incidents, and identify root cause across network environments.
Packet Analytics
Packet analytics refers to the analysis of packet-based network data to identify traffic patterns, performance degradation, anomalies, and operational issues.
Packet Capture
Packet capture is the process of collecting and storing network traffic data, or packets, as they move across a network for troubleshooting, analysis, security investigations, and operational visibility.
Packet Forensics
Packet forensics is the use of packet capture and packet analysis techniques to investigate security incidents, validate timelines, and reconstruct network events.
Packet Loss
Packet loss occurs when network packets fail to reach their intended destination, resulting in degraded application or communication performance.
Packet Replay
Packet replay is the ability to replay historical packet captures using original timestamps to recreate network events and analyze traffic behavior as if it were occurring live.
Packet-Based Observability
Packet-based observability is an observability approach that uses packet analysis and full-fidelity network traffic to provide deeper operational insight than metrics, logs, or flow data alone.
Packet-Level Visibility
Packet-level visibility is the ability to analyze actual network traffic at the packet level to gain detailed insight into how applications, devices, and users communicate across an environment.
Proactive IT
An IT approach focused on identifying and resolving issues before they impact end users.
R
Reactive IT
A traditional model where IT teams respond only after users report problems.
Real User Monitoring (RUM)
Technology that captures actual user interactions to provide insight into real-world performance and experience.
Real-Time Packet Analysis
Real-time packet analysis is the continuous analysis of live network traffic to identify performance degradation, latency, packet loss, and operational anomalies as they occur.
Root Cause Analysis
Root cause analysis is the process of identifying the exact source of a network, application, or performance issue instead of only detecting symptoms or alerts.
Root Cause Analysis (RCA)
The process of identifying the underlying source of an IT issue rather than just addressing symptoms.
S
SaaS (Software as a Service)
