RealNetworks' (formerly Progressive Networks) RealAudio client-server software system enables Internet and online users equipped with conventional multimedia personal computers and voice-grade telephone lines to browse, select and play back audio or audio-based multimedia content on demand, in real time. This is a real breakthrough compared to typical download times encountered with delivery of audio over conventional online methods with which audio is downloaded at a rate that is five times longer than the actual program.

Realtime Blackhole List (RBL)
Realtime Blackhole List (RBL) is a list of IP addresses whose owners refuse to stop sending spam. The RBL usually lists server IP addresses from ISPs whose customers are responsible for the spam, or from ISPs whose servers are hijacked for spam relay. Companies who subscribe to the RBL will know from which IP addresses to block traffic. Most traffic blocking occurs during the SMTP connection phase. The receiving end will check the RBL for the connecting IP address. If the IP address matches one on the list, then the connection gets dropped before accepting any traffic from the spammer. Some ISPs, though, will choose to blackhole (or ignore) IP packets at their routers. The goal here is to block all IP traffic. The RBL was created by Mail Abuse Prevention System (MAPS) LLC., but there are other entities that keep RBLs besides MAPS. We use lists such as, but not limited to, SpamHaus and SpamCop in the CatchGuard feature offered with some of our mail packages.

Requests for Comments (RFC) document series
The Requests for Comments (RFC) document series is a set of technical and organizational notes about the Internet (originally the ARPANET), starting in 1969. Memos in the RFC series discuss many aspects of computer networking, including protocols, procedures, programs, and concepts. The official specification documents of the Internet Protocol suite that are defined by the Internet Engineering Task Force (IETF) and the Internet Engineering Steering Group (IESG ) are recorded and published as standards track RFCs. As a result, the RFC publication process plays an important role in the Internet standards process. Our company uses these standards to make its engineering decisions, including all rules and settings on our servers.
