As an enhancement to the Pingtool, NQA provides multiple test types and more functions.At present, NQA supports ten test types: ICMP echo, DHCP, FTP, HTTP, UDP jitter, SNMP, TCP, UDPecho, voice and DLSw.In an NQA test, the client sends different types of test packets to the peer to detect the availability andthe response time of the peer, helping you know protocol availability and network performance basedon the test results.Supporting the collaboration functionCollaboration is implemented by establishing collaboration objects to monitor the detection results ofthe current test group. If the number of consecutive probe failures reaches a certain limit, NQA’s
