Ethernet

The Path MTU search follows RFC4821 (Packetization Layer Path MTU Discovery).

Step 2Round Trip Time (RTT) Search

Measure of the roundtrip time between the TCP segment sent and the acknowledgment received,

the test has to be done in a network that is not congested to obtain the real round trip delay (not

accounting for network buffer delay).

Step 3Bottleneck Bandwidth (BB) Search

For this step, a Layer2/3 test can be done (RFC2544 or Y.1564) to determine the maximum through-

put rate supported by the network.

Step 4Bandwidth Delay Product Calculation

Based on RTT and BB results, the BDP is computed to estimate the optimal window size that should

be used for testing (Auto mode). User can also specify fixed window size.

Key Metrics:

TCP Bandwidth Delay Product

Transfer Time Ratio

TCP Efficiency

Buffer Delay

TCP Bandwidth Delay Product is the theoretical maximum of data that can be transmitted based on network
delay and throughput rate.

BDP (Bytes) =

Link Bandwidth (bps) x RTT (s)/8

To completely occupy the available bandwidth the Window size must be set to the BDP value.
