Document directory Group Management IGMP operation Encapsulation Internet Group Management Protocol (IGMP) is an auxiliary protocol for IP multicast. So what is multicast? "Multicast" is also called "multi-point transmission" (Multicast). A package sent by a host can be received by multiple other qualified hosts

Preface This article is more, the author in order to save time, improve the efficiency of reading, will focus on the more simple implementation of multicast. And around that end, record some of the content in the UNP. 1. Multicast Addresses Ipv4:class D addresses, in the range 224.0.0.0 through 239.255.255.255, is the multicast addresses in IPV4 (Figure A.3). T

I. IGMP definition and classification Igmp:internet Group Management Protocol, the biggest difference from broadcasting is that IGMP allows each network device to decide whether to participate in a particular multicast group. The IP address of IGMP, the range of multicast IP address is 224.0.0.0-239.255.255.255. 224.0.0.1 represents all computers on the subnet, and 224.0.0.2 represents all the routers on th

Gmrp (garp multicast registry protocol, garp multicast registration protocol) is a multicast registration protocol Based on garp, used to maintain multicast registration information in the switch. All vswitches that support gmrp can receive multicast registration information

network can contain up to 254 computers.Class c ip address range: 192.0.0.0-223.255.255.255 [1] (Binary: 11000000 00000000 00000000 00000001-11011111 11111111 11111111 11111110 ).The subnet mask of the class c ip address is 255.255.255.0, and the maximum number of hosts supported by each network is 256-2 = 254Class d ip AddressClass D addresses are used as multicast addresses by IP addresses. Multicast pro

numbers and host numbers of these broadcast addresses are all 1. If the destination subnet mask is 255.255.255.0, the IP address 128.1.255.255 is a broadcast address pointing to all subnets. Iii. MulticastIP multicast mainly sends data to multiple destinations, and the boot guide service can be determined when the diskless workstation starts. The multi-blog address is a Class D address in the following format:　 1 1 1 0 28-bit

Multicast Technology1IntroductionMulticast technology provides an effective way for a sender to transmit data to a group of recipients. 1. During Multicast Transmission, data is sent to the receiver's multicast address, instead of the unicast address of each receiver. The sender only sends one copy of data, copy the data from the source node to the target node. F

Below is my documents: How NLB works Features of the NLB algorithm: In the NLB cluster, each server has its own static IP address, and all servers in the NLB Cluster also have a common IP a

MBMS Technology and Application Analysis To effectively use mobile network resources, the global Organization for Standardization (3GPP) proposed two broadcast services: one is to use the residential broadcast service, which was developed on the GSM system, therefore, only the text-based broadcast service can be provided. The other is the multimedia broadcast multicast service (MBMS: MultimediaBroadcastMulticastService), where one Data Source sends

local IP address, that is, it should be able to bind itself to a port of a network interface. TCP/IP Study Notes (7)-broadcast and multicast, IGMP Protocol 1. unicast, multicast, broadcast 1. Unicast (unicast) Unicast means data transmission to a specific host. For example, an IP packet is sent to a host. At this time, the data link layer is given in the Data header is very specific destination address, fo

Because it is a simple summary, the fields are not described in detail, and the descriptions of individual fields may be inaccurate, for detailed descriptions of each field in V3, refer to the standard documentation of IGMPv3.

Either party can act as the server. Flexible. ?

. These objects consist of two parts: the Session object is responsible for interacting with the ØMQ socket, and the engine object is responsible for communicating with the network. There is only one session object, but there are different engine types for each underlying protocol supported by ØMQ. Therefore, we have TCP engine, IPC (interprocess communication) engine, PGM engine (reliable Multicast protoco

In the previous article, we talked about a lot of IPv6 address-related content and learned the differences between IPv6 addresses and traditional version IP addresses and the meanings of some new content, now let's expand this part of content. Now we will talk about multicast addresses, fields, and some definitions. IPv6 multicast addresses recognize multiple interfaces. Use an appropriate

of users on a shared media. 19. The standard for Fast Ethernet (100 m) is 802.3u. 20. Self-negotiation is completed using a physical chip without dedicated data packets. Send 16 Bi packets. The entire packet is sent at 16 Ms intervals. 21. The speed cannot be completed through negotiation, but the working method may cause problems. One segment is forced to be 10 m full duplex, and the other end is automatically negotiated to be 10 M half duplex. 22. Self-negotiation priority: 100base-tx full du

indeterminate address, which can be assigned to any node.D. Loopback address for testing the connectivity of remote nodesResolution: 25 Reference Answer: A 26 Reference Answer: BDetailed answer: IPV6 address has unicast address, anycast address and multicast address three kinds: (1) Unicast (Unicast) address The unicast address is the identifier for a single network interface . For nodes with multiple interfaces, any one of the unicast address

There are three types of IPv6 addresses: global unicast addresses (public addresses), local links (communications on the same link), and loopback addresses. No addresses are specified, A unique local address (private address) with an Ipv4 address embedded. Anycast: (as long as one of them receives it) Multicast: (each address must receive data) Address Space: Leading bit Address: the range of the first sixteen-digit Group Allocation status: 0000 0000
