Can MEM monitor real-time service status and performance?
Yes, MEM works hand-in-hand with the latest Ethernet OAM standards advancements to effectively accomplish this task. The IEEE 802.1ag and ITU Y.1731 functionality on Carrier Ethernet network elements provides the ability to monitor the service status and performance in “real time.” The provisioning of the 802.1ag CCM messages per service provides a “heartbeat” between all the endpoints in a service to signal the status of the service. Missing three consecutive heartbeats could indicate the service is down, and an SNMP event would then be generated and sent to the MEM station. Using ITU Y.1731 frame delay or frame delay variation performance monitors allows for tracking of service performance in real time, and thresholds can be set to generate SNMP events if they are exceeded.
