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

FEC adds
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
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.

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.

Because I use IIS7 to Host WCF and WCF uses multiple channel bindings, the web application in the WCF determines that the msmq binding is enabled.

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
methods, which are called multicast delegates.If you call a multicast delegate, you can call multiple methods sequentially consecutively. For this reason, the signature of the delegate must return void (otherwise, where should the return value be sent?). (When a delegate contains only one method, the declaration of its return type can refer to the encapsulated method, not necessarily void). In fact, if the

There are three communication modes in the current network: unicast, broadcast, and multicast. Among them, multicast occurs at the latest time, but it also has the advantages of unicast and broadcast, it has the most promising future.

On the WWDC17, Apple has brought us a big surprise-its browser kernel WebKit will formally support WEBRTC, and future Apple browsers based on the WebKit kernel, such as the MacOS high Sierra, Safari in IOS 11 Browser and Safari Technology Preview version 32, will be used to WEBRTC technology.
The news has attracted countless webrtc developers, even more so that

The advent of WEBRTC has made it possible for enterprises to quickly develop a full platform-enabled audio and video program. Before WEBRTC, the enterprise wanted to develop a full-platform audio and video program, the difficulty, the workload is very large. After using WEBRTC, some common modules in audio and video programs such as audio and video capture, play
