2.0 Architecture overview

Skype's innovative collaboration and communications tools are quick to set up. The

platform is primarily formed from Peer-to-Peer (P2P) nodes.

Skype is largely self-managing. You won’t have lots of work managing the bandwidth

conguration or Quality of Service settings. This means that as an administrator, you’ll be

free to get on with everything else you need to do.

Plus we don’t like to overburden you with new administration tools. We use what’s already

installed on your network. With Skype’s Group Policy Editor (supplied with Windows XP

and above) you can manage Skype software conguration and deployment in your Active

Directory environment.

You’ll need just one new tool for Skype account administration – our web-based Skype

Manager.

2.1 The P2P architecture

You'll need a basic understanding of P2P architecture to optimize your network to use

Skype. It's very different to other communications solutions, being a highly distributed

architecture, mostly relying on P2P communications. A small number of servers manage

functions such as authentication through a login server, but not core functions, such as

presence or location.

You’ll see the benets of distribution (as opposed to centralization) in many areas such

as reduced costs, ease of deployment and network resiliency. Deployment is particularly

simple as Skype-enabled computers nd one another through P2P architecture, adapting

to their environments.

2.1.1 Nodes

Skype consists of three types of peer nodes: ordinary nodes, supernodes and relay

nodes. All three are included in the installation package.

Ordinary nodes run the Skype client. They’re the most common, and are what users

normally see when they install and use Skype.

Supernodes are peer nodes that also perform functions such as assisting with searching

for the location of other nodes. These supernodes are not dedicated and come and go.

They are not servers; supernodes are regular user computers that run the Skype client,

but also temporarily perform other functions.

Nodes can only become supernodes if they:
