|
||||
Project difficulty is listed on a 1 through 5 scale. A 1 would be a project
|
||||
appropriate for a college student with familiarity with C programming, but no
|
||||
experience with the Asterisk code base, or even Asterisk itself. A project with
|
||||
a difficulty of 5 would be something appropriate for a student that already has
|
||||
significant experience with the Asterisk code base.
|
||||
|
||||
1) There are a number of projects that fall into the category of improving and
|
||||
creating new interfaces for developers to interface with Asterisk. To get a
|
||||
bit of an idea for the higher level vision of this effort, see the following
|
||||
wiki page: <http://astridevcon.pbwiki.com/Codename-Pinemango/>.
|
||||
|
||||
Some insight regarding the motivation for this overall effort is captured
|
||||
in this mailing list post, written by Brian Degenhardt.

|
||||
|
||||
Specific project ideas in this area are listed here:
|
||||
|
||||
|
||||
a) Create a generic "data get" layer for Asterisk components to be able to
|
||||
expose data that they maintain. Currently, modules implement specific
|
||||
code to implement CLI commands, manager interface actions, and so forth,
|
||||
while it would be much nicer to have this data available through a common
|
||||
interface. For example, SNMP support has been added to Asterisk but is
|
||||
limited in what it can expose due to the lack of this interface. This
|
||||
project would be to create the infrastructure for this data layer and some
|
||||
uses to prove its functionality. Then, various parts of Asterisk could
|
||||
be converted as time permits. Note that this may end up sharing some code
|
||||
with the "data put" interface in part b.
|
||||

||||

|
||||
|
||||
b) Create a generic "data put" layer for Asterisk components to allow
|
||||
external interfaces to update configuration items, as opposed to having
|
||||
to issue a full configuration reload to account for a single change.
|
||||
This project would involve writing the infrastructure and some basic usage
|
||||
to prove its functionality. Various parts of Asterisk could be converted
|
||||
as time permits. Note that this may end up sharing some code with the
|
||||
"data get" interface in part a.
|
||||
|
||||
Difficulty - 2
|
||||
Mentor - TBD
|
||||
|
||||
c) Improve the performance of cache handling in the event core. The event
|
||||
API in Asterisk provides a generic interface for subscribing to and
|
||||
publishing asynchronous events. It also provides a caching mechanism for
|
||||
events that represent state changes. So, to find out a state, you can
|
||||
pull it out of the event cache. For example, the state of devices as used
|
||||
for presence is handled using this mechanism. The data structures
|
||||
currently used for maintaining the cache are not optimal for performance
|
||||
when the cache gets large. This project would be to write code to
|
||||
benchmark the performance of the caching mechanism, and then implement a
|
||||
new storage mechanism that is more efficient.
|
||||

||||

||||

|
||||
|
||||
d) Develop a method for federating Asterisk servers using distributed events
|
||||
with a transport suitable for communication beyond a LAN. The current
|
||||
event infrastructure includes ways to hook in and distribute events
|
||||
between servers. There is a module which implements this, res_ais, but
|
||||
it is only suitable for federating servers on a high speed LAN. This
|
||||
project would be to implement a new event distribution module using a
|
||||
protocol such as XMPP, or something else if deemed appropriate.
|
||||
|
||||
Difficulty - 2
|
||||
Mentor - TBD
|
||||
|
||||
e) Implement a method that makes it very easy to add synchronous hooks
|
||||
throughout the code base. Hooks are arbitrary callbacks within the
|
||||
internals of asterisk where external components can modify asterisk's
|
||||
behavior. While the dialplan allows applications to control much of the
|
||||
asterisk behavior, hooks allow for business logic to be applied to
|
||||
situations that are not associated with a call (eg: a sip registration
|
||||
hook could allow time-goverened registration period), or for situations
|
||||
that occur during the execution of a diaplan application (eg: codec
|
||||
negotiation hook to apply business logic to codecs proposed in the middle
|
||||
of a Dial command, or a transfer hook to execute business logic when a
|
||||
SIP REINVITE is received).
