H3CSE: detailed explanation of multicast forwarding mechanism and h3cse multicast forwarding Different from unicast, the multicast data forwarding path is based on the tree structure. Different from unicast, multicast forwarding needs to check whether the inbound interface of the packet is optimal. All

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

The three terms unicast, multicast, and broadcast unicast (Unicast), multicast (multicast), and broadcast (broadcast) are terms used to describe how network nodes communicate with each other.

224.0.0.0 to 239.255.255.255 these are called multicast addresses.Let me give you a less rigorous example.There are several hosts that have joined the 224.1.1.1 group.192.168.1.1---192.168.1.2---192.168.1.3---such as these three IP addresses joined the group 224.1.1.1Then the multicast source 10.1.1.1---Send information to 224.1.1.1 this group address, the group of the host will receive the

IP multicast traffic requires a special multicast address, the IP multicast address is a group of class D IP addresses ranging from 224.0.0.0 to 239.255.255.255. Many of these addresses are reserved for special purposes. 224.0.0.0 to 224.0.0.255 's address is best not to use because they are mostly kept for special purposes (such as the IGMP protocol).IGMP is the

The terms unicast, multicast, and broadcast are used to describe the communication methods between network nodes. So what exactly do these terms mean? What is the difference ?. 1. unicast: communication between network nodes is like a conversation between people. If a person speaks to another person, the network technology is used to describe "unicast". At this time, information is received and transmitted only between two nodes. Unicast has been wide

I. Classification of communication methodsThere are three communication modes in the current network traffic: unicast, broadcast, and multicast (multicast), where multicasting occurs at the latest, with the advantages of unicast and broadcast. Unicast: Communication between a single host and a single host Broadcast: When a host communicates with all hosts in the network

Why do Android apps use MulticastSocket to listen for multicast? Why do they connect to different routes and run on different mobile phones? Some of them cannot receive multicast messages. ---------------------------!!

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

With the gradual use of IPv6, our integration with the original IPv4 network has become a key issue in the current transitional phase. We will not go into details about multiple types of excessive technologies here. This article will introduce the basics of the multicast translation gateway model for IPv6 multicast. Multicast translation gateway Model The

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

Unicast can only be sent to one receiver, but when sent to multiple receivers, it is not only consuming traffic, but also time consuming, total traffic = The receiver of the traffic per recipient.Broadcast mode is sent to all hosts, the disadvantage of broadcasting is to cause information pollution, a large amount of information will occupy the network bandwidth.Multicast (multicast): Only hosts that join a multic
