mirjak commented on this pull request. > -setting ECT codepoints in subsequent packets. Doing so allows the connection to -be resilient to network elements that corrupt ECN codepoints in the IP header or -drop packets with ECT or CE codepoints in the IP header. +#### Validation Outcomes + +If validation fails, then the endpoint stops sending ECN markings in subsequent +IP packets with the expectation that either the network path or the peer does +not support ECN. + +Upon successful validation, an endpoint can continue to set ECT codepoints in +subsequent packets with the expectation that the path is ECN-capable. Network +routing and path elements can change mid-connection however; an endpoint MUST +disable ECN if validation fails at any point in the connection. + +Even if validation fails, an endpoint MAY re-validate ECN on the same path to +the peer at any later time in the connection. Okay, then you should say revalidation but maybe remark actually exactly this, that validation is performed on a per-path basis and has do be performed when a path change is detected. -- You are receiving this because you are subscribed to this thread.
