3 | 1 | In this phase the existing XMPP libraries will be analyzed and one will be chosen to be used throughout the project. |

5 | 1 | == Library requirements == |
|
6 | 1 | ||
7 | 1 | * Written in Python (C/C++ could also be used, but a wrapper would need to be written) |
|
8 | 1 | * Support for XMPP server (or component, details later) |
|
9 | 1 | * Ability to use it with the current model used by SylkServer |
|
10 | 1 | * Green threads |
|
11 | 1 | * Callback based IO |

13 | 1 | == XMPP server vs XMPP component |
|
14 | 1 | ||
15 | 1 | The XMPP protocol was designed to be extended by entities called "components" which sit on the side of the server. A component is addressed with a DNS subdomain in the following form: |
|
16 | 1 | ||
17 | 1 | {{{ |
|
18 | 1 | component.domain.tld |
|
19 | 1 | }}} |
|
20 | 1 | ||
21 | 1 | This mechanism is defined in [http://xmpp.org/extensions/xep-0114.html XEP-0114]. |
|
22 | 1 | ||
23 | 1 | With this architecture in place deployment of additional features to an existing XMPP server doesn't require to modify it or write a new XMPP server implementation. The SIP-XMPP gateway should preferably be a component to avoid the need for implementing a full XMPP server, which would be very disruptive for existing XMPP installations that would like to benefit from the SIP gateway functionality. |

25 | 1 | == Library evaluation == |
|
26 | 1 | ||
27 | 1 | The following aspects were considered when evaluating a given library: |
|
28 | 1 | ||
29 | 1 | * Met requirements stated above |
|
30 | 1 | * Date of last release (is it actively maintained?) |
|
31 | 1 | * Example use cases |
|
32 | 1 | * Deployments in real-world scenarios |
|
33 | 1 | * Perceived ability to integrate with SylkServer architecture |
