<p><b>New page</b></p><div>'''TCP over Ethernet:'''<br />
* Assuming no header compression (e.g. not PPP)<br />
* Add 20 Bytes IPv4 header or 40 Bytes IPv6 header (no options)<br />
* Add 20 Bytes TCP header<br />
* Add 12 Bytes optional TCP timestamps<br />
* Max TCP Payload data rates over ethernet are thus:<br />
** (1500-'''40''')/(38+1500) = 94.9285 % IPv4, minimal headers<br />
** (1500-'''52''')/(38+1500) = 94.1482 % IPv4, TCP timestamps<br />
** (1500-'''52''')/(42+1500) = 93.9040 % 802.1q, IPv4, TCP timestamps<br />
** (1500-'''60''')/(38+1500) = 93.6281 % IPv6, minimal headers<br />
** (1500-'''72''')/(38+1500) = 92.8479 % IPv6, TCP timestamps<br />
** (1500-'''72''')/(42+1500) = 92.6070 % 802.1q, IPv6, ICP timestamps<br />
<br />
'''UDP over Ethernet:'''<br />
* Add 20 Bytes IPv4 header or 40 Bytes IPv6 header (no options)<br />
* Add 8 Bytes UDP header<br />
* Max UDP Payload data rates over ethernet are thus:<br />
** (1500-28)/(38+1500) = 95.7087 % IPv4<br />
** (1500-28)/(42+1500) = 95.4604 % 802.1q, IPv4<br />
** (1500-48)/(38+1500) = 94.4083 % IPv6<br />
** (1500-48)/(42+1500) = 94.1634 % 802.1q, IPv6<br />
<br />
N.B. 802.1q describes ethernet traffic behind a router, or in a Vlan. ([http://en.wikipedia.org/wiki/IEEE_802.1Q Wikipedia])<br />
