The Explicit Congestion Notification (ECN) field consists of two bits that denote the end points of a transfer protocol as ECN-capable, or that ECN is not being used. The possible values of the ECN Capable Transport Codepoint (ECT) are: ect1(1) - Use ECN with ECT(1) setting. ect0(2) - Use ECN with ECT(0) setting (recommended). congestion(3) - Congestion is experienced by router. disabled(4) - Do not use ECN Setting the ECN field to 3 is performed by the router to indicate congestion is experienced. ECN is set separately for cache and transport interfaces. ECN can also be set for HTTP Streamers when HTTP is selected as the cache-fill protocol for VVI.
