对OLSRv2草案及其相关规范的研究

优化链路状态路由协议（OLSR）一直是IETF路由区域MANET（移动AdHoc网络）工作组的关注点。最近，IETFMANET论坛通过对OLSRv2的深入研究，公布了3个基础性的规范，即RFC5444（通用化的移动AdHoc网络分组与消息格式）、RFC5497（移动AdHoc网络中的多值时间表示）以及RFC6130（移动AdHoc网络邻域发现协议）。目前OLSRv2草案已进展到第19个版本，将很快成为正式的RFC规范。文中首先叙述了OLSRv2有关的3个基础性RFC规范以及OLSRv2草案对OLSRvl的改进，然后叙述了3种进一步减少泛洪开销的机制。最后，通过OPNET仿真进行了开销总量的对比。

Study on OLSRv2 Draft And Its Related IETF Specifications

The optimized link state routing protocol（OLSR） has been the attracting point of MANET Forum in IETF routing area. Recently, after the extensive research on OLSR, IETF MANET forum has distributed three elementary specifications, i. e. , RFC5444 （Generalized Mobile Ad Hoc Network Packet/Message Format） , RFC5497 （Representing Multi-Value Time in Mobile Ad Hoc Networks） , and RFC6130 （Mo- bile Ad Hoc Network Neighborhood Discovery Protocol）. Now, the newest OLSRv2 draft version is 19, and it will become the formal standards track protocol for the Internet community soon. The three elementa- ry specifications related to OLSRv2 are introduced firstly, and the modification of OLSRv2 draft over OL- SRvl is described secondly. Then, three modification mechanisms to reduce the flooding overhead are de- scribed. In the last. the sum of the flooding overhead is comnared bv OPNET simulation software.
