What's about 1456 bytes?


The minimum size of the receiver buffer in packets can be calculated as follows:

`pktsRBufSize = bps / 8 × (RTTsec + latency_sec) / bytePayloadSize`

Can we consider better variables' names here?
pktsRBufSize -> pktsRecvBufSize
bps -> bpsRate
RTTsec -> secRTT
secLatency
bytesPayloadSize


- `bps` is the payload bitrate of the stream in bits per second;
- `RTTsec` is the RTT of the network connection in seconds;
