You don't, at all.
The initial value for search_high SHOULD be the largest possible packet that might be supported by the flow. This may be limited by the local interface MTU, by an explicit protocol mechanism such as the TCP MSS option, or by an intrinsic limit such as the size of a protocol length field.
It is a section on "search_high", while your question in your previous mail was on "eff_pmtu":
First, it sets eff_pmtu to 1400B. OK? Where did you get 1400 from?
Note that rest of your mail also contains a lot of misunderstandings on the RFC. But, as you don't read the RFC, collecting them is a waste of time. Read the RFC thoroughly again and again, 10 times a day for 30 days. Then, I may reply your further questions if asked off list. PERIOD. Masataka Ohta
