''Upload Speed Sense'' Automatically determines the optimal upload speed. This is done by doing a route trace of 10 clients and finding the last common router. This is the router at the ISP that connects to the rest of the internet. This router is regularly pinged. If the ping time increases (becomes slower) the upload speed is slowed down. This automatically makes room for other applications you are running like a bittorrent upload or web browsing. A minimal upload speed can be specified.

== USS ==

Abbreviation: ''USS''

USS works fine for most people to automatically set the best upload speed. It does give some overhead on the internet connection, and can react slowly. Also some ISPs give priority to ICMP traffic to get good pings and this defies the workings of USS. You might try UDP pings in this case.

The latest versions of eMule automatically enable USS if your upload is set to unlimited (which is the default value). This is supposed to increase overall network bandwidth by optimizing everyones upload.

from the official docs:

USS is a function to monitor the ping times of the connection and to automatically adjust eMule's upload according to this ping value. This ensures that the connection never clogs and will try to keep surfing and online gaming fluid. It is recommended to keep the default settings.

* Find best upload limit automatically

Activates USS

* Lowest allowed upload speed

This is the minimum upload USS must keep. Recommended is at least 50% of your upload capacity

* Ping Tolerance (% of lowest ping)

A initial average ping is determined for the connection when eMule starts. USS will not allow a ping increase over the initial ping times the entered multiplier, e.g. an initial ping of 50 ms and 800% ping tolerance will result in a maintained maximum ping of 400 ms.

* Ping Tolerance (ms)

Instead of calculating the maximum allowed ping by a % modifier also a value in milliseconds can be specified. See next setting.

* Method for ping tolerance

Chooses the preferred method for determining the maximum allowed ping. Either the percentage or the millisecond modifier is used.

* Going up / down slowness

These two values describe how fast the upload limit is adjusted to stay within the ping tolerance. Setting wrong values here will collapse the connection. Keep default!

* Maximum number of pings for average

Sets the number of pings needed to calculate the average response time.

		+	*Inititial ttl. In finding the last common router Skip the first n routers. This might be usefule if the providers blocks pings at the internel routers. Test this with the 'tracert' command. Default =0, If you go higher than 8 you have a strange ISP network. max = 20: not recommended. Setting a too high value will cause\n'Network topology has changed.' verbose messages. Loosing the effectiveness of the USS

+USS works fine for most people to automatically set the best upload speed. It adds minimal overhead on the internet connection and can react slowly. It works even better to still set manually max upload value of 90% of your REAL linespeed, and also set a minimum value in the uss setting. USS will decrease the upload if it is used by other applications.
-Some providers give priority to [http://en.wikipedia.org/wiki/Internet_Control_Message_Protocol ICMP traffic] to get good pings, this defies the workings of USS. UDP pings should be used in this cases.
