Output parameters
The following table lists the output parameters of the twping RPC call.
Parameter | Description |
---|---|
sid | Identifier of the session between the client and TWAMP server. |
source | Address of the vRouter from which test packets originate. |
address: IP address or domain name of the source vRouter. | |
port: Port number from which the test packets are sent. | |
round-trip-time | Length of time it takes for the test packets to be sent from the source vRouter (client) plus the length of time it takes for the response packets to be received from the session reflector of the TWAMP server, which can run on a vRouter or third-party system. |
median: Median round-trip time observed during the sampling period. | |
pdv: Packet-delay variation (PDV), measured in milliseconds. | |
error: Calculated error for timing values, measured in milliseconds. | |
min: Minimum round-trip time observed during the sampling period, measured in milliseconds. | |
max: Maximum round-trip time observed during the sampling period, measured in milliseconds. | |
destination | Destination address of the session reflector on the TWAMP server. |
address: IP address or domain name of the reflector. | |
port: Port number to which the test packets are sent. | |
reflect-hops | Number of hops it takes for the response packets to get from the session reflector to the client. |
diff-num-ttl: A count of how many different hop count values were observed during the test. | |
min: Minimum number of hops taken by a test packet. | |
max: Maximum number of hops taken by a test packet. | |
send-time | Wire time for test packets to go from the sender to the reflector. |
median: Median send time observed during the sampling period. | |
pdv: Packet-delay variation (PDV), measured in milliseconds. | |
error: Calculated error for timing values, measured in milliseconds. | |
min: Minimum send time observed during the sampling period, measured in milliseconds. | |
max: Maximum send time observed during the sampling period, measured in milliseconds. | |
reflector-processing-time | Time it takes to process test packets within the reflector. |
min: Minimum amount of time for processing the test packets. | |
max: Maximum amount of time for processing the test packets. | |
packets | |
num-pkts-sent: Number of test packets that were sent. | |
time-of-first: Time at which the first test packet was sent. | |
num-pkts-lost: Number of test packets that were lost. | |
send-duplicates: Number of duplicate test packets received by the reflector. | |
time-of-last: Time at which the last test packet was sent. | |
reflect-duplicates: Number of duplicate test packets received by the sender. | |
reflect-time | Wire time for test packets to get from the reflector back to the sender. |
median: Median reflect time observed during the sampling period. | |
pdv: Packet-delay variation (PDV), measured in milliseconds. | |
error: Calculated error for timing values, measured in milliseconds. | |
min: Minimum reflect time observed during the sampling period, measured in milliseconds. | |
max: Maximum reflect time observed during the sampling period, measured in milliseconds. | |
send-hops | Number of hops it takes for the packets to get from the sender to the reflector. |
diff-num-ttl: A count of how many different hop count values were observed during the test. | |
min: Minimum number of hops taken by a test packet. | |
max: Maximum number of hops taken by a test packet. |
