    在第三章中闡述了基於ip的網路通信協議的實現，主要是openbsd中的tcp ip協議棧在psos +上的移植和pppoe 、 ppp 、 smtp 、 imap 、 pop3 、 dns 、 dhcp協議、嵌入式web服務器的實現，然後介紹如何利用rtp rtcp來檢測網路有效帶寬，其中的網路有效帶寬就是在第六章提出的碼率控制演算法中確定目標幀率的依據之一。
  2. Currently, it ' s more and more popular to use linux as an embedded system in developing communication devices. but for some reasons in history, some traditional embedded systems, such as vxworks, psos, are still playing a main role in some large enterprise communication equipments. for an instance, the pdsn is also developed in the vxworks embedded system

    但是由於歷史的原因，在一些大型的企業級別的通訊設備的嵌入式操作系統的開發中，主要還是採用比較成熟的一些嵌入式操作系統，比如vxworks ， psos等等，在本文中提到pdsn設備也是採用的vxworks嵌入式操作系統來開發的，但是linux也越來越顯示出它的優勢。
