Endace Latency Monitoring
Endace Latency Monitoring is a unique solution used by organisations to monitor latency between two or more points in their network. The capability is included in every compatible Endace System as part of the Endace Application Suite. Latency measurements are achieved by comparison between precision nanosecond accurate timestamps given to specific packets at either end of a monitored link.
To avoid adding additional traffic to the link, latency measurements are derived using a sophisticated algorithm that identifies unique traffic patterns at both ends of the link. This capability offers the very highest levels of accuracy with zero performance overhead.
Solution Architecture
The Latency Monitoring solution comprises two distinct software components: the Latency Monitoring Agent and the Latency Monitoring Correlator. The agents sit at either end of the target network and the correlator sits separately or in smaller deployments can be co-hosted with one of the agents.
Latency Monitoring Agent
The Latency Monitoring Agent is installed on one or more time-synchronised Endace System, monitoring different points along links of the target network. The Agent is responsible for analysing captured packets, creating a unique identifier for packet content and then sending it, along with a timestamp, to the Correlator.
Latency Monitoring Correlator
The Latency Monitoring Correlator is a central data collection and matching application deployed in a virtual machine environment. It receives information from all deployed Agents, determines when the same packet is observed at more than one location and then calculates the latency between them. The information is stored in the database and then broadcast to recipients as unicast latency feeds, which can then be rendered via a web interface to provide latency metric information, including max, mean, median, and min over time over a set of network links.
