Trace complete.The first column is the network hop count, and the fourth column is the transmit time.
- More than 18 hops may potentially cause issues.
- Transmit times should be no more than 40-120 ms.
Ping Testing
From a workstation within the campus network (preferably the classroom or lab area where students and instructors use SAM), run the following command from the Windows command line:
Ping -t sam.cengage.com- The round trip times should be less than 120 ms for optimal performance.
- Packet loss should be under 1% for optimal performance.
