What's driving the desire for larger packets? A single bit error will drop a whole packet. Larger packets will cause more loss. Cables will need to be shorter or bitrates lower to compensate. Byte overhead of packet headers? Are we seeing degradation of packets per second in forwarding due to the increase in IPv6? Are we seeing IPv6 packets with hop-by hop extension headers (which forward on the slow path)? Increasing the packet size will reduce the number of TCP packets as well as the number of TCP ack packets. TCP ACK packets are significantly larger in IPv6 than IPv4. TCP slow start is faster with large MTU. Is this an issue? Are IPv6 packets with extension headers causing performance degradation in firewalls? Thanks, Jakob.
