The maximum segment size (MSS) value defined in TCP specifies the maximum length of a TCP packet to be sent without fragmentation. Two devices exchange SYN packets to negotiate the MSS value for a TCP connection to be established. If the size of packets for MAP processing is larger than a link MTU, the packets are fragmented. You can reduce the MSS value in TCP, which prevents a service board from fragmenting packets and helps improve MAP efficiency.
If the size of packets for processing is larger than a link MTU, IPv6 packets are fragmented. You can reduce the MSS value in TCP, which prevents a service board from fragmenting packets and helps improve MAP efficiency.
