1. 背景 当前,CORBA.DCOM.RMI等RPC中间件技术已广泛应用于各个领域.但是面对规模和复杂度都越来越高的分布式系统,这些技术也显示出其局限性:(1)同步通信:客户发出调用后,必须等待服务对象完成处理并返回结果后才能继续执行:(2)客户和服务对象的生命周期紧密耦合:客户进程和服务对象进程 都必须正常运行:如果由于服务对象崩溃或者网络故障导致客户的请求不可达,客户会接收到异常:(3)点对点通信:客户的一次调用只发送给某个单独的目标对象. 面向消息的中间件(Message Oriente…

udp 发送ip段报文接口ip_append_data ip_append_data 函数主要用来udp 套接字以及raw套接字发送报文的接口.在tcp中发送ack 以及rest段的ip_send_unicast_reply也会调用:其主要作用是将收到的大数据报文拆分成多个等于小于MTU的SKB,为网络层实现ip分片做准备. ip_append_data 在udp tcp raw 套接字以及icmp 都有被调用到,因此复制数据时有时只需要复制传输层负载部分:此函数并不传输数据,只是将数据放在大小…
