Abstract

With the advance of multicast technologies, source-specific multicast (SSM) has been introduced as a feasible communication model. In the IPv6 environment, since many kinds of equipment can be connected to the Internet as regular end-nodes and assume multicast communication in general, considering the scalability proposed by SSM is very valuable. Regarding an SSM communication over IPv6, an implementation of Multicast Listener Discovery version 2 (MLDv2) on every end-node is indispensable as well as on every router. One of the most concerning points of MLDv2 is its complexity, therefore it may delay the SSM deployment due to its implementation cost. In view of this fact, having an effective and accurate MLDv2 reference implementation is urged and desired for multicast deployment. In this document, we illustrate MLDv2 host-side implementation, mainly the most complex Multicast Source Filtering (MSF) procedure, applied to 4.4BSD kernel. While presenting the implementation concept, design, and logic, we evaluate the behaviors of our implementation. In addition, a performance investigation is also mentioned.

基于IPv6的特定源组播的MLDv2协议设计、实现和评估

随着组播技术的发展，源特定组播(SSM)作为一种可行的通信模型被引入。在IPv6环境下，由于多种设备可以作为规则的终端节点连接到Internet，并承担一般的组播通信，因此考虑SSM提出的可扩展性是非常有价值的。对于基于IPv6的SSM通信，在每个终端节点和每个路由器上实现多播侦听器发现版本2 (MLDv2)是必不可少的。MLDv2最令人担忧的一点是其复杂性，因此由于其实现成本，它可能会延迟SSM的部署。考虑到这一点，多播部署迫切需要一个有效、准确的MLDv2参考实现。在本文档中，我们演示了MLDv2的主机端实现，主要是最复杂的多播源过滤(MSF)过程，应用于4.4BSD内核。在呈现实现概念、设计和逻辑时，我们评估实现的行为。此外，还提到了性能调查。
