Part of this article is reproduced in: http://network.51cto.com/art/200912/168407.htm Before talking about IGMP, it is said that IGMP packets cannot be transmitted outside the LAN (for details, see: http://blog.csdn.net/todd911/article/details/9530633), so how to communicate between routers after hosts in different network segments join multicast groups, do you know which subnet to forward? This is the function of the IP

The little Porter is here again, 51 holidays are over.1. Introduction Broadcast and multicast only apply to UDP because TCP is a connection-oriented protocol (IP address determination) Unicast: The Ethernet frame is only destined for a single destination host, and the destination address indicates a single receive interface. In this mode, any two host communication will not affect th

the data to the kernel can be. Generally, ARP or the route protocol rip should be broadcast.1. 3. Multicasting) Broadcast is a special case of multicast. multicast sends data to a specific host (multicast group, the data broadcast range is smaller (in fact, the broadcast range is not smaller). The

In previous articles, we have explained the content of the IPv6 protocol. We should remember that in IPv6, there are unicast IPv6 routing protocols and IPv6 multicast routing protocols. Now let's take a look at the latter. What content does the IPv6 Multicast Routing Protocol contain? Let's take a look at the following

receive this broadcast data, the network card as long as the MAC address of FF-FF-FF-FF-FF-FF data to the kernel. In general, ARP, or routing protocol RIP, should be advertised in the form of broadcasts.1.3. Multicast (multicast)It can be said that broadcast is a special case of multicasting, multicast is to send data

MulticastUnlike the one-to-one transmission over the network, it is a one-to-many (at least one) point based on UDP/IP point transmission protocol, The multicast router uses the IGMP protocol to check whether the multicast group receiver exists in the network segment connected to each interface, that is, the group memb

"TCP/IP Detailed Volume 1: Protocol" 12th chapter broadcast and multicast---reading notes1. IntroductionBroadcast and multicast are used only for UDP, and they are important for applications that need to transmit messages to multiple recipients simultaneously.Sometimes, a host sends frames to all other hosts on the web, which is the broadcast.Multicast (

the role of multicast and IGMP---------------------------------The so-called multicast, as opposed to unicast and broadcast, refers to the network host will send the data at once to multiple target hosts belonging to the same group. The main use of the IGMP protocol. IGMP is the meaning of Internet Group Management protocol
