IP SLA ICMP ECHO
I referred about icmp echo from ciscopress pages, still couldn't figure out the use of IP SLA ICMP ECHO in troubleshooting. Can anyone select the most appropriate one from the below options?
a. one way jitter measurement
b. packet-loss detection
c. hop-by-hop response time (I think that this is more related to icmp path echo's function)
d. congestion detection
