Skype Network Administrator’s Guide Skype 3.0 Beta 5

2006-10-31 Document version 2.0 Beta

Overview

The Skype software and services provide people with a new, secure and innovative way to

communicate with other people using the Internet as the medium of transport for messages,

whether through voice calls, text messages or other forms of communication.

Skype is the world’s first decentralized telephony network, but it provides far more

services than just voice calling carried over the public Internet.

By using a compact client program (which is available in versions for several popular

computer platforms) a Skype user is able to send or receive text messages, hold voice calls

and exchange data files with other persons using Skype.

Communications with other on-line Skype users are provided free of charge, while certain

premium services, such as the placing of voice calls to standard telephone numbers, are

available for a modest fee.

Skype communications rely largely on peer-to-peer communications techniques in order to

improve the quality of voice calls and to reduce the latency of data transfers between users.

The term “peer-to-peer,” frequently written as “P2P,” is a class of software applications

that rely on resources located at the network edge, such as the large number of individual

personal computers that are always connected to the Internet, rather than relying on large

and costly centralized computer servers. It’s this aspect of Skype networking that makes it

robust and tolerant of network failures. Skype has no single “critical node” upon which the

service relies for its operation.

Description of Skype Services

The utility of Skype services are found in the voice and video calling, file transfer and

instant messaging facilities that are built into every user Skype software client. Underlying

these services are Skype’s directory, presence management and network traversal

technologies.

Skype provides its users with a variety of communications and related services, including

the following:

• Voice calling other Skype user(s)

• Voice conference calling

• Voice calling to traditional telephone lines (SkypeOut)

• Voice calling from traditional telephone lines (SkypeIn)

• Making video calls

• Chat, providing instant messaging for groups of up to 48 participants

• Cross-platform file transfers

• Directory and presence management

Skype user programs have been built for use on several popular computing platforms,

including, but not limited to, personal computers running Windows XP, Windows 2000 or

Linux, Apple Macintosh computers running Mac OS X and Pocket PCs running Windows

Mobile.
