CSCul65167 - ASR5K ECS Shaping of multiple torrent downloads
Feature Changes
Rule Matching for TCP Out-of-order (OOO) Failure Cases
Charging actions configured under ECS service for limiting P2P traffic throughput was not working as expected. While
troubleshooting, it was found that when a single P2P download is performed, traffic is rate-limited correctly; however,
when multiple downloads are done, rate limiting is not as configured anymore, and traffic starts exceeding the
configured limit.

Previous Behavior: When TCP OOO packets were received and when there was any error in buffering those packets at
ECS due to memory allocation failure, these packets were marked as TCP error packets and rule matching was done
accordingly. TCP error was being set for packets when reordering timeout occurred.
