一般来说UDP的最大数据报大小是65535(IPv4环境下,因为在UDP数据包的首部里,使用16bit的字节标示数据报的长度。所以最大长度就是2^16 - 1 = 65535),但是因为iPhone设置了收发缓冲区的大小9216,导致数据收发出现问题了。(发送数据包太大就是Message too large,接受数据包太大就会对数据截断)。 我尝试找了很多地方...

if a UDP message is too large (exceeding the buffer size or MTU size), the rate at which the message is received is too fast, it can cause Linux to drop packets directly because the cache is full.

SendBunch 的时候会去判断当前 Bunch 的大小是否超出限制。IsBunchTooLarge 会判断是否超出 64K。 if (IsBunchTooLarge(Connection, Bunch)) { Bunch->SetError(); return FPacketIdRange(INDEX_NONE); } 2、考虑合并 有些情况下是可以进行数据合并的,同一个 Channel 通道,可靠性一样,合并后没有超过单个 Bunc...

In the case of UDP, size(Length of the data buffer) is larger than actual on your end. That is the reason you are getting the error: EMSGSIZE (Message too long). You can set the transmit size like 1500bytes of each UDP sent with loop. Up0TrueDown...

(co-written with @neild) Linux has recvmmsg to read multiple UDP packets from the kernel at once. There is no Recvmmsg wrapper func in golang.org/x/sys/unix. That's easy enough to add, but it's not ideal: it means all callers of it would...
If too many messages are created at the same time then due to UDP's nature packets will get lost. An internal timer waits before retry. The maximum size of a message is 2^32-1 bytes, which will probably not fit into RAM anyways. Use with big-data might require a higher protocol laye...
