Dense mode 采用推方式传送多播信息,假定所有的网络节点都是接收者,然后再修剪掉向那些不需要多播信息的网络的转发,Flood & Prune 的行为每隔几分钟就要发生一次。 Sparse mode 采用拉方式传送多播信息,除非接收端显式的声明,否则将不会向其发送多播数据。 注意:鉴于Dense mode周期性的Flood行为对网络影响较大,实际的...
dense-mode 多播router之间用的是pim协议,host与多播router之间用的是IGMP协议,dense-mode是router收到multicast traffic之后,首先会检查下进端口的那个multcast source地址是否在IP TALBE上对应那个端口,如果对应,然后就四散到其他端口,如果有些机器不要的,会在收到后发送拒绝信息,然后上游的这个router就会隔一段时间再...
但是映射代理根本就不知道RP在哪里。 问题出来了，咱们来看看Sparse-Dense-Mode是怎么解决了。其实非常简单，如果知道了改组播的RP就使用Sparsemode，如果不知道RP，就使用Densemode。对应224.0.1.39和224.0.1.40多播组处于Densemode。这样既保证了使用Sparsemode的优越性，解决了RP选举时出现的问题。
My question is why is an RP always needed in sparse-dense-mode whether through Auto-RP or statically. It seems like regular client multicast traffic would fall back to dense mode if there wasnt an RP enabled. Although, I know its not considered as efficient, multicast traffic should still ...
The device for realizing the protocol independent multicast in the sparse mode and the dense mode of the invention comprises a multicast public configuration module, a PIM-SM task module, a PIM-DM task module, a multicast routing processing module, and a multicast forwarding module, wherein the...
The 'ip pim sparse-dense mode' command enables PIM to operate in sparse or dense mode, depending on the multicast group. When you enable sparse-dense mode, the interface is treated as dense mode if the multicast group is in dense mode. If the group is in sparse mode, the interface is...
In dense computation the energy only consists of the first two components, and the VDT and IIBLC are gated to eliminate the unnecessary energy. For better comparison, the accelerator energy is normalized to Dense mode. Although VDT and IIBLC induce extra energy, they bring significant ...
sparsity patterns: patterns from $GIT_DIR/info/sparse-checkout used to define the set of files of interest. A warning: It is easy to over-use this term (or the shortened "patterns" term), for two reasons: (1) users in cone mode specify directories rather than patterns (their directories...

RFC 2117 PIM-SM June 1997 2.7 Interoperation with dense mode protocols such as DVMRP In order to interoperate with networks that run dense-mode, {broadcast and prune}, protocols, such as DVMRP, all packets generated within a PIM-SM region must be pulled out to that region's PIM Multicast ...
