说明：  Vxworks下组播路由体系研究与实现.pdf 。在介绍了组播路由基本原理的基础上， 对Vxworks下组播路由体系结构进行了研究，并以DVMRP和PIM 两个协议为例，从总体设计、组播任务、IP协议栈 内核以及组播任务和内核的交互等几个方面给出了它的初步实现。
(Vxworks Multicast Routing System under the Research and Implementation. Pdf. In introducing the basic principles of the multicast routing based on the multicast routing under Vxworks architecture have been studied, and two agreements DVMRP and PIM for example, from the design, mission multicast, IP protocol stack kernel and multicast core mission and several aspects of the interaction is given its preliminary realize.)
