A packet switch consists of a routing engine(table look-up), a switch scheduler, and a switch fabric. The routing engine looks-up the packet address in a routing table and determines which output port to send the packet. Packet is tagged with port number The switch uses the tag to send the packet to the proper output port Eytan Modiano

要设计选择结构程序,要考虑两个方面的问题:一是 在C语言中如何来表示条件,二是在C语言中实现选择结 构用什么语句。 在C语言中表示条件,一般用关系表达式或逻辑表达 式,实现选择结构用if语句 switch或语句。 4.1关系运算及其表达式 4.2逻辑运算及其表达式 4.3if语句 4.4 switch语句 4.5选择结构程序举例
