Network Performance Measurement Tool
Many of Symantec's Veritas software products have network dependencies, hence network strength needs to be good enough for the products to perform correctly.
A few products that depend on Network are: Veritas Volume Replicator (VVR), Veritas Netbackup and Veritas Backup Exec.
So the question often comes up "How can I measure how good my network is? Are there any packet losses happening?"
You can use full-fledged Network Management Software which can give you these answers, or else for short tests you can use this utility from AppCritical, called Standalone Sequencer (sas).
When you install and execute this sas utility, you will need to provide the target IP address between which you would like to check your network. This utility generates a XML output which you would need to upload to Support; with the help of that XML, support can provide you back with a report updating how well your network is performing. Please note, this utility doesn't overload your network and doesn't sends any user data, it simply verifies the network with ping/ICMP requests.
