Network latency is the amount of time it takes for a packet to travel from its source to its destination, measured in milliseconds1.
High network latency can cause slow performance, packet reordering, and network congestion1.
To resolve network latency issues, the analyst needs to measure and monitor various network metrics, such as latency, jitter, packet loss, throughput, and error rate1.
SNMP (Simple Network Management Protocol) is a protocol that allows network devices to exchange management information and report network statistics2.
SNMP can be used to retrieve network metrics from routers, switches, servers, firewalls, and other network devices2.
SNMP uses a manager-agent model, where the manager is a software application that queries the agents on the network devices, and the agents are software components that respond to the manager’s requests2.
SNMP can also use traps or notifications, where the agents send unsolicited messages to the manager when certain events or thresholds are met2.
SNMP can help the analyst identify the source and extent of network latency, as well as troubleshoot and optimize network performance2.
Link state is a routing protocol that maintains a map of the network topology and calculates the best path to each destination3. It is not a tool for measuring network metrics or resolving network latency issues.
Syslog is a protocol that allows network devices to send log messages to a centralized server for analysis and reporting. It can provide useful information for network troubleshooting, but it is not a tool for measuring network metrics or resolving network latency issues.
QoS (Quality of Service) is a set of techniques that prioritize network traffic based on its type, source, destination, and other criteria. It can help improve network performance and reduce network latency, but it is not a tool for measuring network metrics or resolving network latency issues.
Traffic shaping is a technique that controls the rate and volume of network traffic to optimize bandwidth usage and prevent network congestion. It can help improve network performance and reduce network latency, but it is not a tool for measuring network metrics or resolving network latency issues.
