WebThe maximum possible UDP payload is 67 KB, split into 45 IP packets, adding an additional 900 bytes of overhead (IPv4, MTU 1500, minimal 20-byte IP headers). Any UDP packet may be fragmented. But this isn't too important, because losing a fragment has the same effect as losing an unfragmented packet: the entire packet is dropped. Web14 apr. 2024 · One of the biggest challenges with using a TCP and UDP load balancer is passing the client’s IP address. Your business requirements might call for that, but maybe your proxy doesn’t have the information. Of course, there are ways in HTTP to do that quite easily. You just basically inject the X-Forwarded-For header or
A UDP datagram consists of a datagram header followed by a data section (the payload data for the application).
