subtly	7473c93668	UDP Interop. Limit datagrams to 1280bytes. ... We don't have a UDP which specifies any messages that will be 4KB. Aside from being implemented for months and a necessity for encryption and piggy-backing packets, 1280bytes is ideal, and, means this TODO can be completed! Why 1280 bytes? * It's less than the default MTU for most WAN/LAN networks. That means fewer fragmented datagrams (esp on well-connected networks). * Fragmented datagrams and dropped packets suck and add latency while OS waits for a dropped fragment to never arrive (blocking readLoop()) * Most of our packets are < 1280 bytes. * 1280 bytes is minimum datagram size and MTU for IPv6 -- on IPv6, a datagram < 1280bytes will *never* be fragmented. UDP datagrams are dropped. A lot! And fragmented datagrams are worse. If a datagram has a 30% chance of being dropped, then a fragmented datagram has a 60% chance of being dropped. More importantly, we have signed packets and can't do anything with a packet unless we receive the entire datagram because the signature can't be verified. The same is true when we have encrypted packets. So the solution here to picking an ideal buffer size for receiving datagrams is a number under 1400bytes. And the lower-bound value for IPv6 of 1280 bytes make's it a non-decision. On IPv4 most ISPs and 3g/4g/let networks have an MTU just over 1400 -- and *never* over 1500. Never -- that means packets over 1500 (in reality: ~1450) bytes are fragmented. And probably dropped a lot. Just to prove the point, here are pings sending non-fragmented packets over wifi/ISP, and a second set of pings via cell-phone tethering. It's important to note that, if *any* router between my system and the EC2 node has a lower MTU, the message would not go through: On wifi w/normal ISP: localhost:Debug $ ping -D -s 1450 52.6.250.242 PING 52.6.250.242 (52.6.250.242): 1450 data bytes 1458 bytes from 52.6.250.242: icmp_seq=0 ttl=42 time=104.831 ms 1458 bytes from 52.6.250.242: icmp_seq=1 ttl=42 time=119.004 ms ^C --- 52.6.250.242 ping statistics --- 2 packets transmitted, 2 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 104.831/111.918/119.004/7.087 ms localhost:Debug $ ping -D -s 1480 52.6.250.242 PING 52.6.250.242 (52.6.250.242): 1480 data bytes ping: sendto: Message too long ping: sendto: Message too long Request timeout for icmp_seq 0 ping: sendto: Message too long Request timeout for icmp_seq 1 Tethering to O2: localhost:Debug $ ping -D -s 1480 52.6.250.242 PING 52.6.250.242 (52.6.250.242): 1480 data bytes ping: sendto: Message too long ping: sendto: Message too long Request timeout for icmp_seq 0 ^C --- 52.6.250.242 ping statistics --- 2 packets transmitted, 0 packets received, 100.0% packet loss localhost:Debug $ ping -D -s 1450 52.6.250.242 PING 52.6.250.242 (52.6.250.242): 1450 data bytes 1458 bytes from 52.6.250.242: icmp_seq=0 ttl=42 time=107.844 ms 1458 bytes from 52.6.250.242: icmp_seq=1 ttl=42 time=105.127 ms 1458 bytes from 52.6.250.242: icmp_seq=2 ttl=42 time=120.483 ms 1458 bytes from 52.6.250.242: icmp_seq=3 ttl=42 time=102.136 ms	9 years ago
