| Summary | 0003652: inbound quota is enforced, but ignored by sender, leading to connectivity issues | ||||
| Description | In the "test_transport_api_switch" testcases, it seems that the sender sometimes sends at 8kb/s (based on sender's ATS allocation) while the receiver still limits to 1kb/s (not sure why receiver ATS doesn't increase, but obviously that can happen in practice). However, the receivers inbound quota seems to not be communicated (design issue!?), and the receiver then tries to enforce it by throttling reads (if possible, i.e. on TCP). In the test, I've seen this cause sender-throttling of reads by > 35s. The result was then that a "SYN_ACK" was not received in time because of the read-throttle, causing a address switch by ATS to fail (no SYN_ACK within 15s = failure). | ||||

| SVN 35335 defines a quota message and makes sure peers receiving it don't complain. But it is neither generated nor are appropriate actions taken when it is received (yet). | |
| SVN 35357 makes sure that IF a peer gets a quota message, it handles it appropriately and throttles transmission. But we still do not generate those messages. | |
| Should be full implemented in SVN 35362. | |
