As far as we understand, we need TCP header information related to SACK Blocks, ECN, Source Port, SYN flag, ACK Flag, etc for Ack_Filter to work. Since Cake will be deployed at network devices, we're not able to figure out how will be the (higher layer) information accessible. Are we missing out on something that is very obvious?

As far as we understand, we need TCP=20 header information related to SACK Blocks, ECN, Source Port, SYN flag,=20 ACK Flag, etc for Ack_Filter to work.
