Yes, please. |
| 15 |
|
| 16 |
roughly what I can spell out with patience is: |
| 17 |
|
| 18 |
I have borrowed some qos configs elsehwere, applied occam's razor, and |
| 19 |
been satisfied with controlling outbound traffic [using only vanilla |
| 20 |
modules and no user-space]. |
| 21 |
|
| 22 |
wrt to throttling inbound traffic: I have googled, inquired, and seen |
| 23 |
non-vanilla qos modules but have not found an authority with which to |
| 24 |
ask a few very specific questions about ingress. |
| 25 |
|
| 26 |
this means that inbound traffic is not throttled and i just take it easy |
| 27 |
on multithreaded transfers. |
| 28 |
|
| 29 |
goals: |
| 30 |
run 5-10% headroom inbound at all times for voip (and similar realtime |
| 31 |
udp streaming) on broadband, inbound and outbound. This reduces |
| 32 |
upstream packet-queuing which can postpone delivery of voip packets |
| 33 |
|
| 34 |
ideal solutions leading to the goal: |
| 35 |
1) delay TCP packets, never drop. so far I haven't found an *tables |
| 36 |
vanilla kernel module which documents the delay facility of a packet |
| 37 |
class. the collective forum may have covered more ground than I have |
| 38 |
covered |
| 39 |
2) monitor all conntrack'ed tcp windows, delay ACK, and shrink windows |
| 40 |
on large numbers of descriptors in realtime |
| 41 |
3) files of implementation fit the regex /etc/*.d/qos (with package |
| 42 |
deps, but no artifacts) |
| 43 |
4) lock down the reasons why IMQ non-vanilla module/patch is the only |
| 44 |
documented sane inbound qos filter on googled sources and why not to |
| 45 |
treat TUN vanilla module is not an identical facility... |
| 46 |
|
| 47 |
The answer to my unfinished questions may exist in places I haven't |
| 48 |
turned over, however, testing the variations of inbound and outbound qos |
| 49 |
configs is a slow process with alot of phone downtime and advanced |
| 50 |
router side-effects leading to reboots. |
