Penubuhan pelayan x01
Pertama, di bahagian pelayan, gunakan soket untuk menerima mesej Setiap kali permintaan soket diterima, soket adalah dibuka. Utas baharu digunakan untuk menguruskan pengedaran dan penerimaan mesej Pada masa yang sama, terdapat pengendali untuk menguruskan semua rangkaian, dengan itu merealisasikan pemprosesan pelbagai fungsi ruang sembang
Penubuhan pelanggan x02
Penubuhan pelanggan adalah lebih mudah daripada pelayan Peranan pelanggan hanya untuk menghantar dan menerima mesej, dan untuk memasukkan aksara tertentu mengikut peraturan tertentu untuk mencapai penggunaan fungsi yang berbeza. Oleh itu, dalam Pada sisi pelanggan, anda hanya perlu menggunakan dua utas, satu dikhaskan untuk menerima mesej, dan satu lagi didedikasikan untuk menghantar mesej
Mengapa tidak menggunakan satu, itu adalah kerana jika anda hanya menggunakan satu, maka Selepas menerima mesej, yang menerima mesej berada dalam keadaan disekat sebelum menghantarnya. Begitu juga untuk menghantar mesej Jika kedua-dua fungsi ini dilaksanakan di satu tempat, ia akan menjadikannya mustahil untuk menghantar atau menerima mesej secara berterusan
