|
|---|---|---|---|
| 2 | |||
| 3 | In this phase the existing XMPP libraries will be analyzed and one will be chosen to be used throughout the project. |
||
| 4 | |||
| 5 | == Library requirements == |
||
| 6 | |||
| 7 | * Written in Python (C/C++ could also be used, but a wrapper would need to be written) |
||
| 8 | * Support for XMPP server (or component, details later) |
||
| 9 | * Ability to use it with the current model used by SylkServer |
||
| 10 | * Green threads |
||
| 11 | * Callback based IO |
||
| 12 | |||
| 13 | == XMPP server vs XMPP component |
||
| 14 | |||
| 15 | 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 | |||
| 17 | {{{ |
||
| 18 | component.domain.tld |
||
| 19 | }}} |
||
| 20 | |||
| 21 | This mechanism is defined in [http://xmpp.org/extensions/xep-0114.html XEP-0114]. |
||
| 22 | |||
| 23 | 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. |
||
| 24 | |||
| 25 | == Library evaluation == |
||
| 26 | |||
| 27 | The following aspects were considered when evaluating a given library: |
||
| 28 | |||
| 29 | * Met requirements stated above |
||
| 30 | * Date of last release (is it actively maintained?) |
||
| 31 | * Example use cases |
||
| 32 | * Deployments in real-world scenarios |
||
| 33 | * Perceived ability to integrate with SylkServer architecture |
