| 摘 要： | 光纤通道中端口上电、复位或出现故障时需要经过复杂的状态机转化过程才能恢复到正常状态。该文从最基本最简单的N端口入手,分析了它的状态机工作机制,并利用OPNET仿真平台进行建模,总结了4种基本序列协议的工作过程,从中归纳出重要结论:当N端口处于任何一种状态,若它将接收到的有序集原封不动地发出去,则最多经过6个状态,它能自动恢复到激活状态。此结论可大大简化N端口的设计。

| Abstract: | When FC_ports powered-on,reset or encountering failures,a complex state machine is needed to recover from these abnormal conditions.Starting with an N_port,which is the most basic and common port in FC,the FSM mechanism is analyzed and modeled with OPNET.After studying the processes of four kinds of Primitive Sequence Protocols,an important conclusion can be deduced:Whichever state an N_port may be,if it sends the Ordered Sets just received,it can be changed to the active state automatically after at most six states.This conclusion can simplify the design of N_ports greatly. |
