Hyper Text Transfer Protocol (HTTP) - alternative ports used for web traffic. See also TCP ports 80, 81, 8080.
Dreambox 8000 also uses port 8081 (TCP/UDP).
If you're not running web services on this ports, keep in mind that some trojans also use it:
W32.Bufei (04.18.2005) - virus with backdoor and keylogger capabilities. Attempts to connect to URLs for remote access on port 8081 every 3 minutes. |

TCP ports use the Transmission Control Protocol. TCP is the most commonly used protocol
on the Internet and any TCP/IP network. Whereas the IP protocol deals only with packets, TCP enables two hosts
to establish a connection and exchange streams of data. TCP guarantees delivery of data
and that packets will be delivered in the same order in which they were sent.
Guaranteed communication/delivery is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol, a communications protocol for the Internet network,
transport, and session layers. Like TCP (Transmission Control Protocol),
UDP is used with IP (the Internet Protocol) and makes possible the transmission of datagrams
from one computer to applications on another computer, but unlike TCP, UDP is connectionless
and does not guarantee reliable communication; it's up to the application that received
the message to process any errors and verify correct delivery. UDP is often used with time-sensitive
applications, such as audio/video streaming, where dropping some packets is preferable to waiting for delayed data.
