Summary | 0003501: proportional ATS allocation shows little stability | ||||
Description | Looking at a running peer, connections to certain other peers go up and down every few seconds (including between two peers known to run SVN HEAD). Also, the amount of bandwidth allocated by ATS for all peers is highly volatile, often changing as fast as the eye can see (in gnunet-peerinfo-gtk), then staying stuck for 1-2s and then again changing rapidly (usually just after a new peer joins or leaves the set, so this might be related to the excessive churn on connections). This is using the proportional ATS solver, not sure if others are better (did not test that yet). Regardless, we somehow need to try to make the bandwidth allocation more stable (and not fluctuate from 5012 to 5013 to 5014 to 5011 within milliseconds) and try to keep connections open longer. Interestingly (positively), the CORE connectivity remains while the transport-level connections go up and down a LOT. | ||||
Steps To Reproduce | Running a couple of peers for a few hours on the normal network. | ||||
Tags | No tags attached. | ||||

Improved with 33974: ATS only notifies about updated bandwidth when there difference is > GNUNET_CONSTANTS_MINIMUM_BANDWIDTH Topology supports connection request backoff |
