現今提升封包可靠度的方式是存在的,有些是從軟體上著手,有
些是從硬體上,例如Dual System 或是Redundancy Network 或是
Fault Tolerant Network。但是相對的必須付出一些成本代價來建構所需要的機制,而這些方式對於某些特殊封包來說,並非是可靠的架構,例如及時性封包。是否有一種方法只需增加軟體端或是硬體端的設施,即可以達到及時性封包可靠度之提升?在本論文所提的具有改善及時性封包可靠度之網路控制器,是利用兩個相同的封包,經由網路上不同的路徑繞行,來把重要的資訊傳送到目的端。這樣可以避免因網路斷線或是網路交換器故障所造成的通信障礙,使得需要及時知道狀況的目的設備,得以免除遺失封包所造成的重大傷害。另外利用雙重封包機制也可以做到Fault Tolerant Network 所具有的偵測網路障礙之特性,來提早告知網路管理者障礙之發生。除此之外,利用本論文所設計之網路控制器,只需要做到網路交換器或是網路橋接器的RNP 連線,即可以建立出RNP 網路拓撲。
Nowadays, the methods of improving the Reliability of network packets are existent. Some start with the software and others with the hardware. For example, like the Dual System, Redundancy or Fault Tolerant Network, etc. However, it costs a lot to construct the required
mechanism, and these methods are not reliable for some special network packets, like the UDP packet. Is there a method to raise the reliability of UDP packet just to increase the software equipments or hardware equipments? The network controller that improves the Reliability of UDP
Packets in this thesis uses the same two packets, and it transfers the two packets into different network paths to the same destination workstation. This mechanism can avoid the network accidents causing by the network wires breaking or the network switch machine turn-off, and the
destination workstation can’t be hurt from the damage of losing the information carried by UDP packets. Moreover, this method can detect the network accidents as the function of the Fault Tolerant Network by using the dual packets, and send signals to alert the network manager
ahead of time. In addition, by using the network controller, network manager or constructor mentioned in this thesis, the RNP topology can be easily built, just by connecting the RNP type wires to the network switches or network bridges.
