In

downloading content, uploads are used mainly for web server applications and similar processes where the sending of data is critical. Upstream speeds are also important to users of peer-to-peer software

.

Residential services often have higher downstream rates than upstream, while business services are often symmetric.

Symmetric Digital Subscriber Line (SDSL) and T1

, however, offer identical upstream and downstream rates.

If a node A on the Internet is closer (fewer hops away) to the Internet backbone than a node B, then A is said to be upstream of B or conversely, B is downstream of A. Related to this is the idea of upstream providers. An upstream provider is usually a large ISP that provides Internet access to a local ISP. Hence, the word upstream also refers to the data connection between two ISPs.
