老師您好,我是二早班的余則緯,關於下圖,想請問為什麼會出現window內全部都是藍色的狀態?我對全部都藍色的理解是「黃色都已ACK,但藍色都還沒寄出」,然而在每ACK一個黃色時不是都會寄出一個藍色,讓這個藍色變黃色嗎?這樣為什麼還會出現全部藍色的情況呢?謝謝!

Hi,
全部都藍色的理解是「黃色都已ACK,變成綠色的了。但藍色都還沒寄出」
你注意看 FSM,收到一個 ACK 之後,並沒有一定要送出一個藍色 Data,這是兩個事件,兩個動作。

了解,不過如果黃色都已經寄出變綠色的話,因為什麼原因才會不將藍色寄出呢?

我也不知道,或許 sender 在忙別的事情。
設計 FSM 的時候,事件發生的先後順序是沒有定義的。
事件在任何時候來(或不來),FSM 都能正常運作下去就可以了。
事件都是 runtime 的時候才知道什麼時候來。
