The three terms unicast "(Unicast)," Multicast "(multicast), and" broadcast "(broadcast) are terms used to describe how network nodes communicate with each other. So what do these terms mean? What's the difference? 1. Unicast: Communication between network nodes is like a conversation between people. If a person speaks to another person, the term "unicast" is described in terms of network technology, when t

Introduction IP multicast provides a method to send messages to a group of hosts. IP addresses are described in the destination address column of IP datagram. For specific formats and usage, see IP protocol. A group address is also called a Class d ip address. Its range is 224.0.0.0 to 239.255.255. This article mainly describes how to map IP multicast addresses to the corresponding MAC addresses of the rin

Multicast refers to a group of hosts, where one host sends data and other hosts in the group receive the data. First, describe the principles of Multicast: We also regard the vro192.168.192.168.0.1 port as a host, so that four hosts are connected to the vswitch. According to the principle of Ethernet, the switch does not know the existence of the IP address, but only the MAC address. The switch forwards dat

What is multicast?网络中存在3中传播形式，单播，广播，多播。 1. 单播 : 就是1->1 2. 广播 : 1->多(广播域内) 3. 多播 : 1->组(一组ip) 1 2 3 4 5 1 2 3 4 5 Relies on IP protocol implementations首先我们抛出一个问题，要是要你自己在网络中实现这种机制，你会怎么实现呢。哈哈，我的设计大概会是这样。设计思路 : 因为网络是通过ip协议来通信的，那我自然想到是否可以通过某一类标记来标志这种形式就是多播呢，答案肯定是可以的，其实别人也是这样实现的。下面看一张图。 1 2 3 1 2 3 D类IP地址（224.0.0.0到239.255.255.255）标记为多播地址。是吧，别人也这样实现啦。下面

Abstract: multicast communication is a hot network technology. This article describes the basic concepts of IP multicast technology, multicast addressing, Internet Group Management Protocol (IGMP), multicast routing algorithms, and existing multicast routing protocols, and t

In a local area network, administrators often need to send a piece of information to a group of users. If you use a one-to send method, although it is feasible, but too cumbersome, there will often be missed, wrong hair. In order to solve this group communication problem more effectively, a kind of multicast technology (also commonly called multicast communication) is presented, which is based on the IP lay

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

To accomplish useful work, peers in peer-to-peer applications must be able to discover each other and interact with each other. This article provides an implementation of a discovery based on IP multicast. Before a software entity can participate in a direct peer-to-peer interaction with a Peer-to-peer application feature, the entity must discover the appropriate peers to interact with. All available Peer-to-peer architectures provide a solution for

Analysis of Three TCP/IP transmission modes (unicast, broadcast, and Multicast)The Multicast Technology of TCP/IP transmission mode is a type of TCP/IP transmission mode. Before discussing Multicast technology, let's take a look at TCP/IP transmission methods. There are three TCP/IP transmission modes: unicast, broadcast, and

In the project, the Ys Private protocol uses multicast technology, which uses Python to send multicast packets when verifying its security features, and to make a record here. Python has complete support for sockets. Some of the APIs though have a different signature than the POSIX equivalents. It is therefore possible to write multicast servers and clients

The MAC address is divided into two parts, the first 24 bits being the organization's unique identifier (OUI, organizationally unique identifier), and the last 24 bits being assigned by the vendor itself.MAC addresses have uni

I. Data Transmission over an IP Network Multicast technology is one of the three methods of data transmission over an IP network. Before introducing the IP multicast technology, we will give a brief introduction to the unicast, multicast, and broadcast modes of data transmission over an IP network: GroupBroadcast Unicast transmission: Implements point-to-

Introduction In Chapter 1st, we mentioned three IP addresses: unicast address, broadcast address, and multicast address. This chapter introduces broadcast and multicast in more detail.Broadcast and multicast are only used in UDP. They are very important for applications that need to transmit packets to multiple receivers at the same time. TCP is a connection-orie

Class D addresses are used for multicast, which starts with 1110, and the remaining 28 are used to identify multicast addresses (the remaining 28 are non-structured addresses ), MAC addresses starting with 01005e are used to represent MAC multicast addresses, while the remaining 23 are used to identify multicast.
