NetPIPE is a protocol independent performance tool that encapsulates
|
||
|
|
the best of ttcp and netperf and visually represents the network
|
||
|
|
performance under a variety of conditions. By taking the end-to-end
|
||
|
|
application view of a network, NetPIPE clearly shows the overhead
|
||
|
|
associated with different protocol layers. Netpipe answers such
|
||
|
|
questions as: how soon will a given data block of size k arrive at its
|
||
|
|
destination? Which network and protocol will transmit size k blocks
|
||
|
|
the fastest? What is a given network's effective maximum throughput
|
||
|
|
and saturation level? Does there exist a block size k for which the
|
||
|
|
throughput is maximized? How much communication overhead is due to the
|
||
|
|
network communication protocol layer(s)? How quickly will a small (< 1
|
||
|
|
kbyte) control message arrive, and which network and protocol are best
|
||
|
|
for this purpose?
