网络小记3(reactor, proactor)

Standard/classic Reactor:

• Step 1) wait for event (Reactor job)
• Step 2) dispatch "Ready-to-Read" event to user handler ( Reactor job)
• Step 3) read data (user handler job)
• Step 4) process data ( user handler job)

Proposed emulated Proactor:

• Step 1) wait for event (Proactor job)
• Step 2) read data (now Proactor job)
• Step 3) dispatch "Read-Completed" event to user handler (Proactor job)
• Step 4) process data (user handler job)
