[jira] Created: (DIRMINA-144) Traffic shaping filter
Traffic shaping filter
----------------------
Key: DIRMINA-144
URL: http://issues.apache.org/jira/browse/DIRMINA-144
Project: Directory MINA
Type: New Feature
Versions: 0.9
Reporter: Niklas Therning
Priority: Minor
MINA now has basic support for suspending/resuming reads and writes on an IoSession for all transport types. We should use this feature to implement a traffic shaping filter which lets the user configure bandwidth limitations. Both globally and for individual sessions. Here are some configuration options I can come to think of:
* Globally specify a maximum data rate for individual sessions (e.g. max 10 kb/s for all sessions).
* Specify a maximum data rate on a per session basis (e.g. max 1 Mb/s for a particular session).
* Specify a maximum upper limit on the bandwidth used by all sessions in total (e.g. all sessions share a total of 10 Mb/s).
* Configure different traffic classes with different limits to allow for high/low priority traffic and partition sessions into these priority classes.
I'm not sure how advanced it would have to be so please share your thoughts. Maybe point 1 and 2 would suffice? I think 3 and 4 add a lot of complexity since they need some kind of scheduling algorithm to provide fairness between sessions.

[jira] Commented: (DIRMINA-144) Traffic shaping filter

Trustin Lee commented on DIRMINA-144:
-------------------------------------
If this filter goes too phat, then we could split it into more than one small filters.
Plus we need a way to limit the maximum number of unprocessed bytes, so too fast network doesn't lead the codec implementation to throw OutOfMemoryError.
