摘　　要：很多因特网服务的普遍需要是在相同的时间内准确地发送相同的数据到很多的主机。没有IP层的多点传送,组通信的形式将会通过传送数据至每个希望的主机来实现。虽然该方法是简便的,但是它对于发送主机来说是效率极低的。本文引入了一个基于内核的技术,只是使用了最少的附加物至发送操作系统接口,实现高效地促进组通信传送发送操作,文中还说明了该方法的设计和原型实现。A common requirement of many Internet services is to send exactly the same data to a number of hosts at the same time. Without IP-level multicast, this form of group communication is realized by unicasting the data to each desired host. Although this approach is portable and easy to implement, it is extremely inefficient for the sending host. In this paper, we propose a kernel-based technique to officiently facilitate unicast send operations for group communication with only minimal additions to the sending operating system interface and implementation. We present the design and prototype implementation of our approach.
