不同的网络协议都有其存在的必要,每一种协议都有它所主要依赖的操作系统和工作环境。在一个网络上运行得很好的通信协议,在另一个看起来很相似的网络上可能完全不适合。因此,组建网络时通信协议的选择尤为重要。如果可能的话最好只选用一种通信协议,因为每一种协议都要占用系统的内存资源,会影响系统的工作效率,在绝大多数情况下一种协议是完全可以满足连网需求的。 Different network protocols have their own existence, each protocol has its operating system and working environment that it mainly depends on. Communication protocols that work well on one network may not fit well on another network that looks similar. Therefore, the choice of communication protocol when setting up a network is particularly important. If possible, it is best to only use a communication protocol, because each protocol to take up the system’s memory resources, will affect the efficiency of the system, in most cases a protocol is fully meet the networking needs.
