MSS - FreeRTOS

Key Concept: TCP is designed to restrict the size of the segments it sends to a certain maximum limit, to cut down on the likelihood that segments will need to be fragmented for transmission at the IP level.The TCP maximum segment size (MSS) specifies the maximum number of bytes in the TCP segment’s Data field, regardless of any other factors that influence segment size. How MTU and MSS Affect You Network | Network Direction As mentioned earlier, the MSS is like the MTU, but used with TCP at layer 4. Put simply, the MSS is the maximum size that the payload can be, after subtracting space for the IP, TCP, and other headers. So, if the MTU is 1500 bytes, and the IP and TCP headers are 20 bytes each, the MSS is 1460 bytes. tcp - What is the difference between MSS and MTU MSS is Maximum TCP segment size. MTU is used for fragmentation i.e packet larger than MTU is fragmented.But in case of MSS, packet larger than MSS is discarded. MSS is specified during TCP handshake basically in SYN and its value can't be changed after the connection is established. MSS=MTU-40 (IP header (20 bytes) + TCP header (20 bytes)) TCP Throughput Calculator - Tools - SWITCHlan - SWITCH required tcp buffer to reach 100 Mbps with RTT of 80.0 ms >= 976.6 KByte maximum throughput with a TCP window of 64 KByte and RTT of 80.0 ms <= 6.55 Mbit/sec.
